Queen Victoria (181-101) was the first English monarch to see her name given to the period of her reign whilst still living. The Victorian Age was characterised by rapid change and developments in nearly every sphere - from advances in medical, scientific and technological knowledge to changes in population growth and location. Over time, this rapid transformation deeply affected the countrys mood an age that began with a confidence and optimism leading to economic boom and prosperity eventually gave way to uncertainty and doubt regarding Britains place in the world. Today we associate the nineteenth century with the great change in English literature in particular the area of poetry. Victorian poetry as it’s most commonly referred to, was very much concerned with contemporary social problems. Change rather than stability came to be accepted for the first time as normal in the nature of human outlook. Victorian poetry can be classified as Early (187-51), Mid(1851-70) and late(1870-101) saw the progress in poetic style from the Romantic Era to the Modernist Era, it also saw the rise of the popular form of poetry referred to as the Sonnet.

Some of the most famous poets of the Victorian era include;

ɨ Ralph Waldo Emerson (180-8)

ɨ Elizabeth Barrett Browning (1806-61)

As mentioned previously the Victorian Era was a period in British history where much change occurred not only socially, economically or politically but attitudes and values towards different aspects of society also changed. Therefore attitudes can be described as Victorian if they reflect the values also expressed during this period. One such example is the attitude towards health. Health occupied the Victorian mind more than -- religion, or politics, or improvement, or Darwinism. In the name of health, Victorians flocked to the seaside, tramped about in the Alps, dieted, took pills, sweated themselves in Turkish baths, and adopted different systems of medicines to reflect this. For the sake of health, they invented, revived, or imported a multitude of athletic recreations, and England became, in Sir Charles Tennysons words, the worlds game master. Literary critics thought of health when they read a new book of poems; social theorists thought of Health when they envisioned an ideal society.

This attitude towards health is also strongly expressed in today’s society and we therefore can say that we hold a very ‘Victorian’ view on health and well being. In today’s society many other Victoria views are seen to be somewhat conservative, however when these views were made public they sparked much controversy and changed the face of British society.

“The sun never sets on the British Empire,”

Rudyard Kipling

Recessional serves as a warning against England’s precarious position in trade and against the complacency setting in to the British Empire. Kipling warns about England’s Dominion where Australia and Canada act as its poles. He expresses his fear about the possibility of England loosing all its pomp of yesterday and loosing all control over the colonies, he does this by comparing Britain to the great trade cities of Nineveh and Trye and how they disappeared, later becoming ruins. He also points out the idea of blinding power and ignorance on the British empire’s behalf, believing that this could lead to it’s downfall;

“ If, drunk with sight of power, we loose”

Finally the poem contains a strong warning to the British not to exploit other races;

“ Such boastings as the Gentiles use, Or lesser breeds without the Law”.

In terms of the major techniques used by Kipling to present his view ,one must make reference to the rhyme scheme employed by Kipling and the enhancement this has on the poem’s flow. The use of the rhyme scheme ‘aabbcc’ enhances the effect of the poem and reinforces the prey ‘like’ flow to the text. Also the fact that the last two lines of each stanza make significant religious reference reinforces the idea of the poem’s prey like structure;

“Lord of Hosts, be with us yet,

Lest we forget- lest we forget!”

In relation to the prey like structure of the poem the very title, ‘Recessional’ carries great religious weight, referring to the piece of music played or sung at the closure of a religious service and alludes the reader to the idea that the British Empire’s rule is coming to an end. In terms of another technique used, the very language alludes the reader to the power of the British Empire and the power that God holds;

“Who’s awful Hand we hold”,

“ Judge of the nations, spare us yet,”

“Our Far Flung battleline.”

Finally Rudyard Kipling’s perspective of the British Empire and the date in which the poem was written explain of the perceivable downfalls in the nations past, present and future.

“Loss of faith”

By Matthew Arnold

The poem ‘Dover Beach’ explains of the ‘loss of faith’ within the church during the Victorian era, and does so by using the ocean and the tide to represent this ‘loss of faith’. It is through Arnold’s use of imagery, language and presentation of issues the reader is automatically forced to react somewhat sympathetically but also forced to realise a hidden message ‘behind the words’.

In terms of imagery the most meaningful image is that of the sea, hence the title. Throughout the poem, the sea is used as an image and a metaphor. At first, it is beautiful to look at in the moonlight, then it begins to make hostile sounds grating roar, tremulous cadence that evoke the general feelings of sadness. In the third stanza, the sea is turned into a metaphoric Sea of Faith, a symbol for a time when religion could still be experienced without the doubts brought about by the progress of science, in particular the introduction of Darwinism. It is behind this image, Arnold presents the concept of religion withdrawing itself from the human mind and leaving only darkness, and in turn causes the reader to contemplate the effect science had on religion throughout the Victorian era.

The use of language throughout the poem also has a strong impact on the reader and adds to the poem’s already dramatic tone. With the use of phrases like “human misery”, and “ naked shingles of the world”, Arnold alludes the reader to the fact that without religion the world is somewhat ‘naked’ and expresses a general feeling of misery. Finally the language used in the 4th stanza lines five and six sums up what Arnold perceives the world to become, and raises the question that if these basic human values do not exist, what remains? Along with Arnold’s use of language, his poetic treatment also enhances the effect of the poem. The use of repetition, in particular ‘is’ reinforces the loss and darkness felt by Arnold himself. As for rhyme, there is no apparent rhyme scheme, except in the fourth stanza where a rhyme scheme of abbacddcc can be detected, along with seven lines of iambic pentameter.

Finally the poem uses the concepts mentioned previously to force the reader to assess religion and it’s value but also gives an insight into the role religion played during the Victorian era and the mixed feelings expressed. Best of all the poem leaves the reader with the idea that if the bottom has fallen out of everything the only thing left to do is be ‘true to each other’.

“a sombre idealism”

by Lord Alfred Tennyson

Tennysons poem Ulysses is very much a reflection on the life of the heroic character Ulysses, his dangers past and now his growing tiredness of having to stay home and ‘grow old with the rest’. The poem uses a very unique way of expressing the feelings of Ulysses, instead of making use of comparison the poem uses a method of discussion, thereby capturing the reader’s interest and offering explanation.

“ Free hearts, free foreheads- you and I are old”.

The poem very much presents the age old saying of ‘live life to the full’ and does so by pointing out the fact that even though many battles have been fought and many adventures had there is still challenges to complete,

“Tis not too late to seek a newer world.”

Finally the poem combines past, present and future to reflect on life and it’s challenges and at the same time uses strong phrases such as “ made weak by time and fate, but strong in will,” to convey a meaning and purpose to the reader. However the poems greatest downfall is the expectation of the readers background knowledge of Ulysses and other ancient myths.

Much of the poetry produced during and after the Victorian era was very much related to the social, economic and political changes occurring. For instance middle class liberalism was a very powerful movement throughout the Victorian era and was brought about by poets such as Thomas Carlyle, J.S. Mill, Matthew Arnold, John Ruskin, and Walter Pater in the aim of modifying liberal assumptions about human nature, economics, and social organisation. Also the advances in science became widely spread in much of the work produced throughout the Victorian era and writers like Lyell, Wallace, and Darwin introduced the belief that when science advances, so does human society. Along with the new dominance of science comes anxiety over the loss of the older, religious outlook. It was poets like Matthew Arnold who expressed the fact that many British citizens found it hard to maintain their Christian beliefs.

Finally the most distinguishable characteristics of works, in particular poetry, throughout the Victorian poetry was their expression of human thought and emotion. They achieved this through reflecting on issues effecting much of British society and expressing the views of not merely the upper class but the middle and lower classes.

The inter-relationship between the health of the economy and interest rates is an incredibly important and often discussed topic. And recently in Australia the link between these and the housing sector has been heavily scrutinised. Penm et al. (14, p. 41) have even suggested �housing activity is a leading indicator of general economic activity”. In the Australian economy, the housing market is booming, some believe out of control. Whether or not the boom is sustainable is a topic which has serious consequences for the growth or contraction of the economy, and where opinions differ wildly.

The housing market has been experiencing a new high recently. Lenders lent a record $ billion in March to people buying, building or refinancing their homes (Colebatch 00). This increase in demand for housing has pushed up the cost for some first homebuyers to a prohibitive level. The prices for housing are experiencing 0 per cent to 5 per cent annual growth (Dempster 00). This likely to be the effect of a shift in demand for housing and building, exceeding any shift made to supply in response. As the diagram (Pindyck & Rubinfeld 001, p. 6) shows, the shift of the aggregate demand curve from D1 to D outweighs the shift in supply made in response (S1 to S). This results in increased quantity (Q1 to Q), but also increased price (P1 to P).

Quantity demanded has increased over a large number of housing markets at once because this is a �hot” period for residential real estate markets (which experience �hot” and �cold” periods). A hot period is one where �average selling times are short, the volume of transactions is higher than the norm and prices are rising’ (Krainer 1, p.14). Many are predicting that this demand will not last and that �the residential construction boom is likely to peter out”(Statistics of Australia’s Economy 1-004 00). At these prices, first home buyers account for just over 15 per cent of loans for the year to March, which is close to an all-time low (Colebatch 00). Also, there is oversupply in some areas, especially high-density unit markets in Sydney and Melbourne (Wade 00). This is because oversupply leads to a reduction in prices, since there are more providers on the market (S1 to S) without corresponding demand. The competition for buyers sends the prices down (P1 to P).

But a review of the building industry, conducted by Robert Meller and Jason Tyrrell of

Cheap Custom Essays on Housing, Interest rates and the Australian economy

BIS-Shrapnel, has predicted demand in the building industry will be sustained (Wade 00), as well as suggesting interest rates on home loans could reach 10% by 006 (Teese 00, p. 6). While the authors of the review concede, There is now substantial risk that the looming oversupply will see a sharp and protracted correction” (What is the housing market doing? 00), they feel the oversupply and soaring prices will result only in a lull over this year. Both residential and non-residential building commencements will move into a fully fledged boom over the two years to 005-06, driven by strong economic growth, as well as increasing underlying demand in both sectors, the report says.

The rationale behind this is that the Australian economy is growing out of the trough in the business cycle it experienced in 000-001. It is expected to grow in 004 along with an anticipated global recovery and increased output from farms (Statistics of Australia’s Economy 1-004 00). BIS Shrapnels forecast is for strong economic growth over the next three years, sending the unemployment rate below 5 per cent. �This will create labour shortages that will push wages higher and increase inflation. In turn, the Reserve will jack up interest rates aggressively”, the report says. Here, the relationship between the state of the economy and interest rates is expressed explicitly.

The effect of a recovering economy will be both workers and producers will expect aggregate demand to increase, triggering an increase in prices. To maintain the same real wage level, workers demand wage increases, changing aggregate supply. This results in the price level rising again in the next period. This is a continuing positive rate of inflation (Crompton et al. 00, p. 74-75).

At point A, workers and firms expect the price level to be 100, shown in the supply curve SRAS100. Workers and firms expect aggregate demand to shift to D, making the price level 1. Workers then demand wage increases to maintain their real wage, shifting aggregate supply to SRAS1. The price level rises again in the next period, resulting in an ongoing inflation rate (Crompton et al. 00, p. 74).

The Reserve Bank of Australia aims to keep the inflation rate of the economy within two to three per cent. The BIS-Shrapnel review proposes that in the middle of 006 inflation will need to be controlled, as it gets too high. One of the methods of controlling inflation available to the Reserve Bank of Australia is to increase interest rates. Because interest rate increases making borrowing money more expensive, the measure lessens spending in the economy. This acts to limit the increase of aggregate demand in the economy. As Alan Thornhill (00, p. 17) says �household consumption could retreat quite quickly”.

Interest rate rises do reduce the rate of inflation, but with a reduction in demand comes a reduction in output, and so increased unemployment as production is cut and workers are no longer needed. If the economy slows and you get rising unemployment, many people will have great difficulty servicing mortgages,” the review says (Wade 00).

The review predicts that at 10% interest rate level, the level of new building will fall 0% in the two years between 005-006 and 007-008 (Wade 00). Demand for building decreases when interest rates rise for several reasons. Firstly, the cost of borrowing money increases, so buying or building a house is less affordable. Also, businesses are producing less after the rate rise, so there is less of a need to purchase plant and capital, including buildings. So, the relationship here between interest rates and investment, including housing, is obvious.

This diagram shows the effect of raising interest rates on the economy. Workers and firms expect aggregate demand to increase to D. They negotiate increased wages, which shift aggregate supply to SRAS140, based on this. But the price rise that results is higher than the Reserve Bank of Australia’s target. So, the RBA increases interest rates, moving aggregate demand back to D (Crompton et al. 00, p. 76). The price level is reduced, but so is output, and unemployment increases.

With fewer employment opportunities in the community and home buyers with variable interest loans paying higher interest there is �some severe pain” to be �felt in the community” (Wade 00).

It is obvious how inter-dependent the state of the economy, interest rates and the housing market are. The level of activity in the economy, or even the performance of one sector such as housing, are leading factors in any change of interest rates by the Reserve Bank of Australia. Any changes in interest rates can act to inflate of deflate the economy, and also an individual sector like housing. And deflation of an important sector such as housing can be the cause of �significant general economic fallout” (Thornhill 00, p. 17). It is also now obvious why the state of the housing market, or any attempts to influence the economy through monetary or fiscal policy, are so keenly watched and debated.

Cognitive Psychology

Week 1 � Lecture 1

Cognition � matching the world to internal representations

- language and word recognition

Write my Essay on Cogntive Psychology for me

essay writing service

- pattern recognition

- visual imagery

- memory

we will focus on memory

- problems � when cognitive processes go wrong

brain damage


amnesia � viral infections, car accidents, severe alcoholism, old age (alzeihemers) � they don’t lose knowledge of the world, but once it has gone beyond immediate awareness you cant recognize/remember what has actually happened to you.

Memory is relevant to clinical psychology

False memories - how they occur and how to distinguish b/w false and true beliefs

Transfer appropriate processing - if you match retrieval process in memory tests to the way in which you learn.

Cognition Process

Conscious and subconscious processes

· Conscious � reminders we give ourselves to remember events

· Unconscious � no conscious insight of how processes work, cant study by introspection � no conscious awareness.

How to study cognition

· experimental psychology, accuracy or reaction time in normal subjects.

· At the mind level � brain function - neuroscience done on animals � but not much done on cognition.

· Studying brains in action in humans à functional brain imaging � what aspects of brain activated in certain tasks

· Cognitive neuropsychology � look at those with brain damage in specific areas � localized brain damage which affects cognitive processes in one area, but not others i.e long or short term memory � is their overlap in processes??

· Computer processing � Wont cover

Week 1 - Lecture


1. Definition of memory

- Result of learning

i.e modification of behaviour and/or knowledge through experience.

Complicated by ,,4

. Stage of memory � stages of processing

· Encoding (acquisition) - study phase (phases of experiments on memory)

· Storage (retention) � distractor phase

· Retrieval � test phase

Encoding � learn material - at a party and processed info. Not deliberate study

Storage � before you try and access memory it must be retained in this intervening period

Test phase � trying to remember what happened

Overall memory performance depends on all stages and interactions b/w them.

How could memory fail??

- could happen independently at any of these stages

- fail to encode

- not stored

- test � retrieval � couldn’t find right cue

- it is much more complicated than this

. Examples of memory -many different things are referred to as memory

· Recall a list of words

· Recognize a familiar face (retrieving)

· Remembering your 4th bday

· Remember a phone number long enough to dial it

· Remember the name of an object (word finding difficulty)

· Skills

· Lean to ride a bike/ learn to read

· Remember what you have to do tomorrow (prospective memory) remember you have to buy bread on way home from work - wont cover this type of memory

4. forms of memory (retrospective) - already happened - these examples are al related but not the same cognitive phenomena. They are functionally independent but not completely independent (some) at mind level. Systems of memory also independent at brain level.

Schacter and Tulving (14) - memory systems

a) short term/long term memory - Peterson and Peterson; Baddeley 160’s and 70’s

- primarily based on duration

- info retained transiently or permanently

tasks repeat immediately (STM)

memory span (STM)

recall after week delay (LTM)

b) episodic/semantic/procedural - Squire; Tulving 70’s and 80’s

- primarily based on type of info stored

- personal events (episodes) episodic v general knowledge (semantic) v skills (procedural)

tasks recall studied paragraph or film

identify famous faces

reading inverted text

c) Explicit/implicit memory - Schacter, Jacoby 80’s and 0’s

- based on conscious/non conscious nature of retrieval

- information recollected “explicit” vs expressed on behavioral measures “implicit”

tasks recall, cued recall, recognition

priming on stem completion (first word that comes to mind)

CAL _________

Priming as decrease in RT’s in lexical decision or naming à present something on screen either real or nonsense words and measure speed taken to make decision whether real or nonsense. If it comes up again after a delay � we are quicker (this is an index of implicit memory � even though you may not remember whether that word was shown twice or not) independent of conscious recollection. EXPLICIT v IMPLICIT

Not based on type of info

d) overlap in distinctions

· different distinctions within memory are not mutually exclusive

· eg. You can have explicit retrieval of info from semantic memory etc

· semantic - generalized piece of info

· priming - picture of prince Charles - then picture of princess Diana - quicker to say she is a royal over a politician - primed by prince Charles in previous trial (implicit)

· prosopagnosia � inability to recognize faces - brain damage, localized disability or could be developmental.

· If gave a picture of prince Charles � wouldn’t be able to give name. don’t have explicit consciousness but do have unconscious ability (implicit)

· Many combinations of these distinctions

· ST, explicit � conscious measure

· ST, implicit � priming effect

· We cant have conscious recollection of procedural memory � ie. Riding bike

5. forms v psychological systems

- different storage??

- Or different methods of access to common storage system??

- Neurological basis of distinctions??

Yes there is evidence of neuro basis to these distinctions but info being stored (explicit/implicit) is not in different forms - single storage system but brain systems which allow access either directly (conscious) or indirectly (unconscious)

6. This course

- what is memory/ how do we remember complex questions � must define type of memory you are interested in.

- consider each form independently

- NOW � we will focus on explicit memory and memory for episodes (transient) and divide this up into - transient (ST) and enduring(LT)

Week � Lecture 1

Short term memory / working memory

Evidence for short term/long term distinction

1. limited memory span

- present series of digit to subject

- increase by one each times

- ask them to repeat back to you

- “span” = no of items that gives perfect recall (in correct order) 50% of the time � either half of subjects tested or half of trials on individual subjects

- where does subject fail? At what point do they fail


Work out last one you get correct �the test doesn’t continue once you have failed

There becomes a point where you cannot recall

Drop out b/w 6-8 digits

Capacity of STM seems to be around 6-8

- Miller (156) 7 +/- - reason for calling it a magic number was that this same number came out as memory span for almost all subjects for a whole range of stimulus classes - binary, decimal, letters of alphabet etc. 1 syllable English words.

- Keeping them verbally active

- Capacity of short term memory was 7 “things”

- Span of 5- items with binary digits, decimal digits, letters of alphabet or English words.

- Span based on number of “chunks” eg 145 v 186 - history effect � might use strategy of 145 end of war and you remember that as a meaningful chunk rather than disconnected digits

- Span for letters is

o 6 if selected at random

o Consenant-Vowel-Consanteant syllables � if organized in this way, they are pronounceable and can use this as a strategy to remember

o 50 in meaningful sentence - can repeat back a large number of letters if it is in a meaningful sentence..

- i.e perceptual and recognition systems identify familiar units (chunks) and STM holds 7 +/- of these

· Its about chunks � earlier perceptual recognition, semantic processing affects ability of span

· We do have a limited memory span � verbal rehersal, before they disappear

· Traces are transient, different from long term processes � where we have encoding that is not difficult, it is just done

· What is a thing???????? A letter is one letter, but words have many letters � CHUNKS

. Recency Effect

- - lists of unrelated words

- Postman and Phillips (165), Glanzer and Cunitz (166/)

· given a random list of words, asked to remember a lot of those (about 0)

· pushed beyond memory span � impossible to repeat all back, cant keep them in STM

· immediately told to report words back in any order that you like

· plotting accuracy - serial position curve

· on x axis � serial position � where original item appeared

· words presented first remembered well

· words in middle remembered pretty badly (-7) 15% recalled correctly

· words presented at the end are remembered increasingly well � last item almost ceiling levels (80%)

· Recency effect - those presented last � retrieval from (working memory) short term memory. People spit out last words first, they are active in working memory, those other words have been pushed out, they cant remain active, others replace them..

· Primacy effect � those presented first �why are first ones learned better??

· Primacy effect probably due to proactive interference � as you have to learn more in a list, it becomes harder to learn each successive one as the previous one interferes� this is a property of long term memory, not important as a distinction b/w STM and LTM

· Most retrieval for words presented previously is from LTM, working memory is better for recall than long term memory

· Limited short term memory store

· i.e limited STM sore which is Dumped” first in recall of list; will most often contain last few words

- order of recall last first

· people write down the STM memory words first.

· This is reasonable good evidence from STM component separate from LTM

Double Dissociation in SPC (serial position curve) components

(a) brief filled delay �

· manipulation introduced - give list of words, then told 7 and asked to count back out loud � this is used to stop us keeping those last few words in working memory.

· This will get rid of recency effect, but if only a relatively short delay, this shouldn’t affect performance on long term memory task. The lower two graphs have done this.

· Do this for 15 seconds or 0 seconds � recency effect disappears but doesn’t get rid of long term effect, if subject not given another task, then you do not lose recency effect � we are able to keep them active by rehearsing them. The 0 second delay is the same as for 15.

· when you aid in filled delay, performance doesn’t drop to zero � it is at level of items retained in short term memory, memory accuracy is a sum of two components those recalled from LTM, and items recalled from STM

· By using a manipulation you can alter short term memory but leave LTM the same

· no recency effect, LT value delay

(b) Glazner (17)

· showed recency unaffected by word frequency, recency was unaffected, but influenced earlier part of serial position curve. word frequency, including low frequency words, presentation rate effect long term memory, age of participants effects long term memory but not recency part of curve, divided attention (doing tasks at once) has a big effect on ltm, but has little effect on stm.

· There are functionally distinct forms

· At the level of the mind, they are distinct

· There is a double association that you can demonstrate

· What about at brain level????????? YES!!

· Looked at through brain damage to different areas of brain

· Areas which affect long term memory and areas that affect only short term memory

Lecture , Week

. Neuropsychology


e.g HM (Milner, 166) - patient called HM - late 0’s, 156, given brain surgery for epilepsy to stop epilepsy, it worked helping epilepsy, but couldn’t retain anything in LTM

- trouble with Long term memory

- could remember pre trauma events and knowledge

- never heard of president Kennedy

- cant retain any info in long term memory

- he can implicitly, but not explicitly

- he has been tested over and over, never recognizes testers

- cant learn new material

- normal span � perfectly intact working memory

- one on one interaction OK sentence to sentence � can carry on normal conversation as long as his attention isn’t distracted. Must be about neutral things, as soon as he is distracted, you will have to reintroduce self if you go out of room for 5 mins.

- cant transfer info to long term memory

Baddeley and Warrington (170)

Serial position curves for amnesiacs � normal recency effect, poor LTM

è have STM ok but cant add to LTM

è copy of this on handout

è learn 0 words � show normal memory for those words at end of list

è in HM shows high recency effect but cannot remember those items presented more than 4 trials ago (almost zero)

STM damaged patients

- Shallice and Warrington (170) - patient KF

- Digit span of only - digits

- LT learning normal � asked to learn list of 0 words, and recall 0 mins later, this was normal

- Serial position curve shows opposite pattern to amnesia � early part normal but severely reduced recency effect � looked more like filled delay

- Have LTM ok but damaged STM

Together - Double Dissociation at brain level

This adds a lot to evidence for physically and functionally distinct systems - STM and LTM


1. methodological - a ST task testing over short delays will be tapping both short term and long term memory

- sum of STM and LTM to give total performance (serial position curves) � small contribution from LTM

- need to distinguish tasks from memory forms tasks are assumed to tap � not a one to one correspondence, it is easier to get a solely LTM memory task, but difficult for STM

. Theoretical - most active info is in STM for processing

- we are paying attention to these things the most, they come from current perception but may also come from LTM

- this info can be retrieved from LTM as well as from current perception

- i.e STM = “working memory”

Limited Duration or capacity??


- trace decay (naturally) , interference (next item pushing out previous item) or both??

i.e 1. limit on time because need to re-rehearse item before it decays � we need to rerehearse before it decays - decays before you have time to get back to rehearse

or . limit on number of slots to be filled each new item pushes out old one??

- storage spaces are limited, can think of 7 items at once, once the 8th item is added, one has to fall out of slot,

Or a combination or both????

Previously said “limit” but didn’t distinguish possible causes.

ANSWER Time limit/Trace decay - not a fixed number of slots


but - exact span depends on articulation rate

- Baddeley, Thomson and Buchanan (175)

o Span task � 5 items 1-5 syllables long - wit, sum, harm, bag, top VS university, opportunity, aluminum, constitutional, auditorium

o Recalled decreased as number of syllables increased

o Also measured reading speed for lists

o For all lists got same answer no recalled/reading rate = seconds of words

o if it takes you longer to say a word out loud, it will also take longer for subvocal articulation.

o Number of words you can accurately recall corresponds to number of words you could subvocally rehearse in seconds

o Span is the number of words than can be rehearsed in seconds

o Is it duration not number of syllables?? YES � Baddeley

Must test in native language

Conclusion limit on short term memory is not slots but an indirect result of trace decay of each item you are trying to remember � they begin to decay unless you can rehearse.

We get capacity limitation (interference) because of duration limitation.

Is rehearsal necessarily phonological (hear) � in normals for verbal stimulus, YES, but can rehearse visual info (mental rotation on text)

What if born deaf?

Don’t have the phonological system, don’t know what words sound like

Kilkham (1) - PHD thesis - deaf native signers

Looked at memory span related to how long it took you to sign the word in sign language � not articulation rate of equivalent spoken word

Span was normal, but how long it took to rehearse words in sign language

· Normal system - but all about how long it took to sign words

· Signers internally rehearse without phonology

· Suggests a number of potential “rehearsal loops” of limited duration/capacity

· Different loops deal with different types of information

Why do we have a short term memory system??

Week , Lecture 1

What is STM not for??

Two views

1. Atkinson and shiffrin (168) idea - WRONG

- in order to remember permanently, must go through STS to get into LTS

- more rehearsal = more likely to transfer (better LTM), need to actively rehearse to transfer into long term memory

- functional role of short term memory was very dull, only used as a portal to long term memory, didn’t have its own function

- underlying assumption � saving info to long term memory is very difficult

- model of rship b/w short term and long term memory - key idea

è functional role only to keep (some) info around long enough to be saved permanently in LTM.

- “modal” model � also often called modal model

- “rise and fall of STM” = rise and fall of this model, not of STM


- sensory register � very brief � 100’s of milliseconds


- Don’t have to go through STM to get to LTM (neuropsychology -patient KF, digit span of -, but normal long term memory, can cause brain damage that knocks out STM but doesn’t affect LTM, this wouldn’t occur if the A&S model was correct )

- We can keep far more info in LTM that we can actively rehearse in STM

- Simple rehearsal = poor LTM, it helps to some extent, but not really.

- LTM improved more by processing for meaning than for rote rehearsal

- Natural learning is learning for meaning � eg incidental learning, having a coffee with friend and remembering that conversation

- Intentional learning is trying to learn.

What is STM actually for??

NOT for strengthening trace via rehearsal so that info can reach LTM

1. Working memory

- limited capacity system

- incoming stimuli and info from LTM meet there - she finally left that jerk � current info with info from LTM

- info from whatever source is in WM is currently most active

current stimuli à sensory perception processing è WM


neural mechanisms take a little while to consolidate LTM

don’t need to go through STM

- can retrieve info from LTM and rehearse it and make it active � arrow back to LTM

- FUNCTION - “working” in that processes info as well as holding it

a) storage and computation � thinking, reasoning about material

b) subcomponents in WM � a collection of limited capacity “stores”

this makes it extremely useful.

- Need to keep stuff active long enough and to integrate it with LTM

a) storage and computation

- if WM does both, does each function interfere with each other??

· Posner and Rossman (165) computation with storage or recall of a set of digits

- gave ss 8 digits to learn 8 4 4 5 1

- after various delays recall first digits

- we are trying to rehearse these to store them and keep them active

- in the delay you are asked to do mini reasoning tasks some simple some difficult

1. recording � write down last two digits you heard over and over - easy

. add � sum the last two and write down over and over � not just storing but processing the sum of + 1 � slightly more difficult

. backward � count by ’s from last pair

4. classification � most difficult � classify them as grater than 50 or less than 50

- then recall first three digits at delays, ss presumably rehearsing theses

- the harder the computation task, the poorer the recall

· Baddeley (186) showed the opposite of the above

o Storage interferes with reasoning

o Does performance on reasoning task gets worse as you have to rehearse more digits in working memory

Ss rehearse digits out loud on graph referred to as “concurrent load” � how many digits told to rehearse - 61616161 or 674674674674

- REASONING TASK - statements True/False

eg. A follows B - BA (True)

or B is not preceded by A - AB (False)

- measured how accurately you could do it and also your reaction time

- reasoning time increased with size of concurrent digit load

(BUT not catastrophic - why??? Even with 8 digits you were still able to do it, it just took a little longer.

Take home message storage interferes with computation and vice versa

- evidence for working memory � not just storage, it is actively working on it

Increasing digits didn’t increase error rate, it is still in front of you, you can go back and check

It was the time taken that was affected by the concurrent digit load

b) subcomponents in WM

interference is not always found b/w storage and reasoning

eg. Halford, Bain and Mayberry (18)

- concurrent load only weakly affects performance on algebra problems

- different type of reasoning task didn’t have much of an affect.

- given a load of digits (b/w ,4,6)

- then had to solve x + 6 = in head, whilst recalling digits

explanation for this

Anderson, Reder and Lebiere (15) -

- for many people algebra problems can be imagined being done visually

- maybe one occurring in verbal rehearsal loop and one in visuospatial sketch pad, and because using different components of the system, they don’t interfere. Doing algebra on visual blackboard in mind

- added condition where substitution required � so there couldn’t be complete independence of processing

ax + b = - need to work out what x equals and told that a = 1st digit of concurrent load and b = nd digit of concurrent load

once you required this substitution � the amount of storage and the performance on reasoning task did interfere with each other again

latency � time taken to solve algebra problem

- without substitution � no effect of concurrent load

- with substitution � got large effect

- get interference b/w storage and computation only to extent that tasks forced to use same processing system

- weak null effects of interference found when tasks can be done by different WM sub systems


· Verbal rehearsal loop - phonological loop - verbal rehearsal of concurrent load

· Visuo-spatial sketchpad - used for algebra problems, when no substitution

· Central executive - can transfer info from b/w these loops, this is more conscious � this is a vague notion.

Week , Lecture

What is STM for (CONT)

. integrating info spread over time

eg. Language processing

retaining info long enough to

- integrate words into sentences

- integrate key sentence ideas in text

a) Use in single sentence processing

- cognitive neuropsychology approach

- patient TB (Baddeley and Wilson, 188) - has STM memory problem, arose from epilepsy

- very smart man - professional mathematician, memory problem after epilepsy

- some LTM problems, but learning list of words was normal

- very severe STM damage � digit span 1-

- problems in real word comprehension

- if Baddeley correct this STM problem should lead to problems in language processing

- doesn’t have trouble with meaning of single words

- ok on short simple sentences

- but in real world comprehension he has a bit of difficulty, he misunderstands what they have meant.

- when tested experimentally - if due to problems in STM, his understanding of sentences should be fine, if they are very short and simple syntactically , so no difficult in integrating

simple true or false decisions - he was quite good at this

“bishops are made in factories”

“slippers are sold in pairs”

this is greater than his digit span � so maybe he couldn’t do, but when processing sentences you make an ongoing consolidation process - “bishops are made” is one concept, this is why he can do it.

When it became more difficult

so poor he became distressed with verbose sentences

“it is commonly believed and with justification that slippers belong to the category of objects that are bought in pairs

- couldn’t tell us whether this was true or false

these were the two extremes but we was tested over sentences of 1-10 words

comprehension fell from 100% è 0% with 10 words

- within sentences of a particular length, they changed the grammatically difficulty of the syntax. He performed worse on those sentences requiring higher memory load

“The boy the dog chases is big”

- the boy is big � but these arrived at different times, need to integrate after a time delay

è STM used to help with long and/or syntactically complex sentences.

- we only looked at this in terms of patients, but this is the same for normals.

- good piece of writing � simple, well structured sentences, well integrated

b) used in text comprehension

- Danmen and Carpenter (180)

- measured “reading span” � measures capacity in working memory. The max no of sentence-final words that the subject can recall.

- read sentences for meaning as well as for knowing they must remember the sentence final word they know they will be tested on comprehension � memory tests

- given a number of sentences, this is more difficult than digit span.

- some are very good � it is good at separating people .

- looked at effect of individual differences in “reading span” - some people in normal range are better or worse than others.

(NB realistic measure of WM ability)

- ss then asked to read paragraph of text with referent (WAYNE), read some intervening sentences (GUFF IN THE MIDDLE � I like girls blah blah blah) , then a pronoun

- the task was to say who/what the pronoun referred to � he/she/it, who or what was the referent - see handout

- manipulation was to vary the number of intervening sentences

- general prediction � if WM involved in both � then performance will get worse as person has shorter reading span, and more intervening sentences. If good reading span can cope with more intervening sentences than those with poor reading span.

- ss with higher spans showed best comprehension, with least fall off with more intervening sentences

- do these individual differences in reading span go on to correlate with peoples ability to understand text or say a conversation - yes this is what they found

à YES, we use WM in text comprehension as well as the reading of single sentences out loud as often they are quite long.

We use it for many other functions

Conclusion - What is STM for??

Ø working memory

storage and computation

- why? For interpretation of stimuli spread out over time eg info that doesn’t arrive all at once. (eg. Lanagauge; reflecting on past events/thoughts- make it active again in WM)

Ø Where integrating of distinct bits of info required

Ø The “hub of cognition” � extremely important

- but we have only talked about conscious cognition - one view is that working memory is consciousness

long term memory and short term memory � processes, components and functions may be different, as they are independent.

Week 4, Lecture 1 - 1/8

Long term explicit memory

- two general approaches

1. how much is remembered versus forgotten (quantity when correct) � what factors effect how to remember

. what is remembered (true? False?; types of errors) - its more than this, often we remember something that is incorrect, false memories

1. How much is remembered?

Observable memory performance is influenced by encoding AND storage AND retrieval

Encoding (aka study, learning) � how can we help ourselves remember info


- does practicing more help??? At encoding stage we are holding storage and retrieval constant


- recall of paired-associates [words that don’t naturally go together, but have been paired in context of experiment] (eg. Dog bike) given the first word as a cue, and then asked to recall, bike, when given the word dog.

Results of this as a function of amt of practice (power function) - Anderson (181)

- as practice trials increase less errors are made. � fewer forgetting errors

- if you know material better, you will be able to produce it more rapidly

- paired-associates as a function of spacing of practice

- Keppel (164) - 8 times one day or twice per day for 4 days

results better with distributed practice than massed.

- see graph - interesting results also varied the retention interval � straight away up to a week later. As you increase delay, memory get worse, generally this is what they found.

If you tested immediately after, it didn’t matter if you learnt it either massed or distributed, in fact massed practice was best immediately. 1 day delay, massed practice plummeted. After 7 days, could barely recall anything. Distributed practice stayed at very high levels of remembering across the week.

- theoretical interpretation practice makes stored trace stronger in LTM, perhaps massed practice, doesn’t make the practice sessions distinct.

Divided attention

If you do two tasks in the study phase, learning ability is detrimentally affected.

Single task � learn a list of words, in study phase, they are given a distractor task

or dual task paradigm

Murdock (165) � primary task learn spoken word list. Reason being � secondary task was a visually presented task cant do two visual tasks. Simultaneously they were asked to sort cards Varied attention demands in the card sorting procedure in easy attention demand just turn cards over, or more difficult attention demands sort cards into ,4, 8 categories say divide into living non living things, 4 categories etc.

- as you took more attention away from primary task being able to remember was impaired significantly

- memory worse with divided attention.

Levels of processing/elaboration

- all about semantic processing and active semantic processing

- Lab for LOP (level of processing) (Craik and Lockhart, 17) � refers to whether you process the info for meaning or not for meaning (ie, for some other reason) learning by rote � is not learning for meaning. Learning the alphabet - is learning for rote. Times tables also learnt by rote, rather than meaning

non-semantic � does dog rhyme with boat?

Semantic � is dog linked to puppy? - process for meaning

- LOE (level of elaboration)

- everything being studied in the study phase is for meaning, but how deeply is it being studied for meaning??

eg. Bobrow and Bower (16)

dog bike ---- WORST

vs the dog chased the bike ----BETTER

vs make up your own sentence

linking dog with bike ----BEST i.e a generation effect - sentence constructed by you, rather than by experimenter, your generation of sentence helps you remember.

è if you provide meaning yourself, you will remember better

why is this?? Storage and retrieval phase are held constant

- Anderson and Reder (17) idea of LOP/LOE increase memory because trace left by meaningful encoding provide ss with more retrieval routes. - an active retrieval phase, the more richly it is encoded, the more hooks you have to come back to.

i.e an effect of encoding because certain forms of encoding make retrieval easier; not because they make the stored trace stronger. You are getting a richer trace, which is easier to retrieve later on.

Organization of material

- Bower, Clark, Lesgold and Winzenz (16)

wanted to investigate how memory was affected by type of semantic structure you provided to subjects in order to help them learn info in the first place.

Tested memory under circumstances

- hierarchal semantic structure to help aid memory - recalled 7/11 words


- random order - recalled only 1/11

for examples


metals and stones

common metals

rare metals etc

precious stones

rare stones etc

can use structure to help you

when semantic structure is provided in study phase, they recalled 7/11 words

remembering structure provides us with cues to remember specific material.

Intention to learn

(counterintuitive result!!)

no effect of intention per se.

- eg hyde and Jenkins (17)

- level of processing study

- ss rated words for pleasantness � high LOP or

- whether they had e’s or g’s in the world - low LOP

- half ss in each condition warned of a memory test (intentional learning) half not (incidental learning)

- effect of LOP but not intention

à apparent effect of intention arises because intention makes us more likely to use strategies above.

Ø does it matter if you try to learn the material or not?

Ø No effect of intention per se.

Ø Intention means you use other strategies to try and remember.

Week 4, Lecture 14/8

Conclusions from encoding

Practical all else being equal, study should be with full attention, (self) elaborated and distributed over time .

Theoretical likely that many effects of encoding are not on trace strength, but on ease of retrieval (i.e content of retrieval)

Retention (aka storage)

- not a great deal we can do in the storage phase

Forgetting function

- the longer the delay, the more likely you are to forget, but what is the shape of this forgetting function?

- Krueger (1) paired associate recall.

- performance fell very rapidly after first week or so, after this it was slower decay � power function � shape of curve.

Interval in days � power function

- Squire (18) probability of recognizing name of a tv show as a function of time (no of years since its cancellation)

- given real tv show names or name of false tv show that have never existed, had to distinguish b/w the two

- found a power function in shape, rapid decay after first few years of delay, after 6 years only recognize 60% and after this it really evened out. 50% is chance, because you can guess if a real show or not, so still better than chance after 15 years. Higher level of processing in this experiment. Seen the show etc etc.

interval in years � power function

- Linton (18) � studied rates of forgetting everyday events. Interval in years - linear function

- everyday she wrote down a particular event that occurred in her life that day � dramatic or dull depending on the day, but something particular to that day

- after a period of 6 years she went back and got someone to pull out cards from those years and then asked them to invent events, and she had to say what had occurred and hadn’t occurred. After first 6 years fairly linear decay pattern. 50% is chance. There is hardly a surprise � the longer the delay, the worse memory performance gets.

What if you learn material more strongly in the first place? Do you lost it more slowly? With the same amt of study test delay

Degree of learning and forgetting rate

Slamecka and McElree (18) � extra trial of practice on sentences. Delays up to 5 days

Got subjects to learn sentences for later memory test

Got either

study trials


4 study trials

- better at remembering if you have 4 trials

- did you show slower decay if you had learnt it 4 times versus times? - no over the 5 days there wasn’t a difference for trials versus 4 trials, two lines are parallel, even though you learnt material better, the rate of decay is exactly the same for 4 trials and trials, losing info at same rate!!

Wixted and Ebbeson (11)

- looked at memory for single words

- to increase strength of trace - gave you longer or shorter exposure time to words, only go through list once, but see word for either 1 sec or 5 sec duration. Dealys up to 40 seconds

- still lose info at same rate, you are better at recalling for 5 sec study, but you are losing information at the same rate, when you take logs of number recalled. The lines are parallel.

But this is just rote repetition � do you get more resistance to forgetting with semantic/elaborated study??


We not only have delay but we have interference b/w study and test phase.

- retroactive � interference of new learning on old

- there is an interference effect

- retro � in the past - learned a piece of info - old � then you are presented with interfering or new info which may interfere with old. Having learnt a second thing interferes with the retrieval of the first

paired associates

see graph

A-B�A-D A-B�C-B A-B--rest

Much worse worse Best

- general finding with paired-associate learning interference worst when given potential confusion

- interference with old knowledge

e.g Bradshaw and Anderson (18)

- learnt old fact about Mozart (tested) - first thing you learnt about mozart


1. by itself � no interference (control)

. with conceptually unrelated facts to his trip to Paris - (worse) -makes memory worse

. with conceptually related facts to his trip to Paris (better) � makes memory better, even better than the control condition

è new material can interfere or enhance - depending on whether or not it can be integrated with the old

Conclusions from retention

All else being equal, performance better if delay shorter and intervening material either very distinct from target or able to be integrated with it.

Practical implications - not a lot we can do about this.

Week 5, Lecture 1 - 0/8

Retrieval - type of test

Standard tests of memory in experimental setting

Ø Recognition cued recall free recall (see text)

Ø Free recall � not given any cues

Ø Cued recall - given clues to help remember

Ø Recognition - different ways

Old/new recognition � study 0 items - in test phase presented with 60 items, half old, half new and need to say if old or new

Two alternative forced choice - study 0 items - presented in pairs one in pair will be old one new, forced choice.

The more cues given, the more assistance, the more likely you will be to be able to retrieve info.

Nature of distractors - recognition tests

Ø In recognition, get worse as distractors are more similar to (less distinct from) the target.

Ø In recognition memory � as distractor items are more similar to target, memory gets worse.

Ø Eg. Learn list of words � all man made objects � distractors were all animals. This would be easier � as you would know that all in study phase were not animals � how well you can reject items is also important.

Ø Is the same true for phonetic memory? Not really � long term memory � is more hingent on meaning. We remember meaning more than form in explicit long term memory.

Ø Similarity in meaning presents problems rather than similarity in form

Ø Line ups - examples - recognition memory test, asked to identify perpetrator. - this is notoriously inaccurate, better if you don’t know how many distractors there will be. Pressure to choose one.. one coming up at a time, is better. Choosing one perpetrator is easier or more difficult depending on the nature of the distractors

Ø Cross race deficit - better at remembering faces of people of your own race. White Americans definitely show deficit for recognition of black Americans.

Ø Classic example person reported they had been attacked by black man in Britain � not enough black people for lineup - they ended up presenting 1 black man (who they suspected) and 5 white policeman with black painted faces.

Ø Important in a practical sense also!!

Encoding specificity (tulving, 17)

Extent to what happens in retrieval phase matches what happens in the study phase

If it matches � then memory is better than if it mismatches

- match in external cues b/w study and test improves memory, if they mismatch this reduces memory

- external cue = associated word � something paired with target word � something in outside world

study phase trying to remember CALENDAR, but it is paired with mother.

Test phase recall word that started with CAL

Tested under situations, with different cues

Mother - CAL



Memory is better when the cue is repeated b/w study and test phase.

- external cue = environmental context Godden and Baddeley (175) � more practical

divers underwater or on land, at study test.

Best memory when either studied on land and tested on land, or learned underwater and tested underwater

Memory much poorer when there was a mismatch - land/water - water/land

Mckone and French � not quite as extreme as the diving example, if you don’t manipulate it as strongly, the effects aren’t as great.

Looked at environmental context effects either outside or inside.

Chifley library � inside

Hancock � outside

Same pattern for outside vs inside on ANU campus

- told people that she was looking at effects of mild exercise on memory and also poor budget, and honors students weren’t able to have access to labs

see handout -

cued recall test

if study inside - memory better if tested inside

if study outside � memory better if tested outside

what environment you were in when you learned information, and when you need to retrieve info improves memory if conducted in the same place.

Transfer appropriate processing

- referring to match b/w retrieval and encoding enhances memory

- but focus on internal processing done by subject, rather than the external environment

- emphasis on processing!!

- not match in external cues per se that enhances memory, but these are effective because produce match in type of internal processing done by the subject. Emotions physiological state etc.

mood dependent memory eg people recall more negative events from their life when they are depressed than when they are not.

- same for drunk vs sober.

- e.g our lab - Semantic -S Rhyming -S

but - S-R = R-R

manipulated type of processing person did rather than external cues

see handout

memory is better in same same than different

levels of processing and study test match � transfer appropriate processing

semantic study phase advantage is reduced if the retrieval test is a rhyming cue.

Not exactly the same cue at study and test

Doglog, frog - not repaired with log in test phase - repaired with frog

Dog puppy, hound

External cues were different, but the same type of processing was induced b/w study and test - study for meaning or for phonetics

Instead induces same types of processing � semantic or perceptual

Is encoding specificity really attributable to transfer appropriate processing (internal state of processing)

- bjork and Richardson-Klavehn (18) perhaps ss mentally recreate original context (eg imagining yourself underwater?? conscious

- no evidence that this doesn’t occur, but…

- may help but Mckone and French (001) found 0/8 ss used this strategy spontaneously - this didn’t occur consciously

- this is not an explanation for why context effects occur,

- it may help.

Week 5, Lecture � 1/8

Conclusions about retrieval

- all else being equal try to generate a cue that access distinctive nature of event and match test processing to study processing

- information may be in there even if you can’t retrieve it in a given test

take home message study test match enhances memory this provides evidence for the fact that info may be in there even if you cant retrieve it at the time of the test

methodological problems with concluding “no” memory � this doesn’t mean it hasn’t been encoded or stored � there could be something with retrieval of person

is failure to perform about failure to encode or inability to retrieve

theoretical is everything still there?? But we just cant retrieve it.. we don’t have the right retrieval cues.

Overall Conclusions

- real world memory take interference and substantial delay for granted � having other events happens is taken for granted, there are some things we can do to improve memory

how to improve memory???

- best to semantically elaborate material at study � give meaning, integrate it with what you already know, space your study, match retrieval context to study, generate distinctive cues at test.

Memory accuracy in relation to standard memory disorders


- general point - nobody’s memory is perfect

- we will look at damage to brain

- head injury - car accident etc - not progressive disorders - but we look at sharp injury or events.

Temporary Disorders

Symptoms of these types of disorders

Theoretically is there a storage deficit? Or did they learn it and cannot retrieve it? This is good to be able to test for temporary disorders

Mild head injury

- temporary loss of past memories when person wakes up

amnesia � problem with memory

retrograde amnesia � problem with past memories - forgetting events that occurred prior to injury, could remember them before injury, but cant since injury

anterograde amnesia - fail to learn or retrieve new information, trying to learn things for the first time after injury cant be done

- this is in respect to when injury occurred - old/new info � before/after injury

mild injuries (knock you out for a couple of hours )

- person has forgotten events for some time before injury - cant remember injury or things that happened on the day of injury, or even info that happened in the couple of days prior.

- the worse the injury � the more time into the past the memory problems last

- unconscious for two weeks - may be quite permanent

- unconscious for hours - going to be less permanent

- length of coma � tends to be a good indicator of the severity of problems that will be associated with memory

islands of memory returning - remember certain things - but cant connect - isn’t placed properly in time.

If mild (an hour) - perhaps after a few days will remember everything except for like 0 seconds or so before injury. - e.g can never remember accident itself

è This is known as retreating retrograde amnesia

this indicates that this is retrieval deficit, rather than a storage deficit.

Amnesia is not due to damage to storage, but damage to ability to retrieve for a short time

Very rare disorder - transient global amnesia (TGA)

Become an amnesic for like 4 hours/8 hours etc

PERHAPS -Vascular problem in brain - mini stroke � temporary blockage of blood etc.

This symptoms for TGA are the same as for PGA (permanent) but in TGA they resolve


- severe retrograde amnesia � may forget last 10 years of life, can remember up to certain period, eg may forget that you are married but don’t forget childhood

- anterograde amnesia - inability to learn info

tricky to do tests on TGA � as they are in this state for a short period of time.

Three different types of test

- paired associates

- recall story

- recall diagram � draw it

paired associates - in learning new material


11 patients during TGA

same subjects a month after TGA had gone away (learning new set of words

control subjects

all matched to clinical patients

nothing intrinsically wrong after TGA episode

terrible problems learning material during TGA episode

recalling a story experiment

given a mark for each core idea of story remembered

delayed condition - filled delay � control 4/8

TGA after � 4/8

TGA during - close to zero

Immediate - during tga its almost as good as controls and after TGA

Diagram copy/recall - test of learning visual material

Problem with memory processes, not just lanaguge processing or visually processing.

TGA terrible at delay

Working memory component is fine

Adding new info to LT memory and retrieving it is the problem??

After episode they go back to normal - severe AA during episode

How do we test for RA??

Public events and personal events (standardized)

Don’t really have to compare to controls, we can compare them to themselves which provides some nice data.

Week 6, Lecture 1 � 7/8

Properties of transient global amnesia

Retrograde amnesia � forgetting of material that was known prior to head injury

Memory for public events who had been president of US

Memory for personal events marriage, graduation etc

TGA � can compare subject while in amnesic state to same subjects performance after TGA has resolved.


Once TGA had resolved that could report 15 events (40% of these events they could recall during amnesic episode

Graded retrograde amnesia � they are worse for the most recent things when in amnesic state(ie last two years)

Summary performance of TGA for retrograde amnesia

- temporally grade retrograde amnsiea � older memories are more intact during amnesic episode, working memory is still intact. We remember older memories better than more recent ones

after much better retrival of that same information.

Retrograde demonstrates deficit in retrieval, not damage in traces themselves

It stops access to them, but not a deficit in storage

- but also a deficit in new learning � memory for events within the TGA period never returns; suggest that it was never encoded/stored. Things learnt during TGA episode is never recalled. (although this is only tested with explicit memory tests)

- defintley a retrieval deficit

- may also be a storage/encoding deficit.

Note so far these TGA patients (Which are hard to get hold of) have only been tested with explicit memory tests - what about implicit?? Perhaps it can only be recalled unconsciously. This has never been examined, for normal amnesia this is the case.


People assume its something to do with a mini stoke, blockage of blood flow, doesn’t predict future stroke. It is a bit of a mystery.

Permanent organic disorders

(1) classic amnesic disorders

aka � “global amnesia” - problems with all domains of memory � personal events, public events, pictures, memory for words etc

general symptoms

almost always include anterograde amnesia (AA) � learning new stuff

sometimes include AA and RA - looks exactly like symptoms for TGA but permanent

- very rarely, RA occurs alone � cant remember past life, but can learn new stuff

can hold conversation about something neutral

but if the conversation involves retrieval from long term memory they struggle

causes stokes, head injury, encephalitis, anoxia (cardiac arrest, lack of oxygen), surgery, dementia (alzeihemers), Korsakov syndrome (alcohol abuse) � most common cause

which brain regions are affected - medial temporal lobe (particularly hippocampus) and diencephalic structures (thalamus, hypothalamus)

- in pure cases, all other non-memory functions intact

- patient HM. Surgery for epilepsy in 15 - has awareness of deficit. Describes life “like waking up from a dream…everyday is alone in itself, whatever joy I’ve had and whatever sorrow I’ve had” - it is strange to have awareness of problem

- Jimmie G (Sacks, 185) - Korsakov syndrome

was in US navy until 165, perfectly competent. Heavy drinker. Developed occasional memory problems in the late 60’s, but “able to cope”. Had no insight into his problems. In late 170, “blew his top” became delirious and excited, admitted to hospital. (last - weeks) patients confabulate a lot.

- seen by Sacks in 175 4 yrs old � had memory problems for 4 years since onset of Korsakov syndrome. This delirious state resolves, but now become aware he has forgotten parts of previous life and cant retain new information. In Korsakov syndrome other areas of brains affected, but the sever amnesia is the most striking symptom of the syndrome

- social skills intact

- if it has dropped out of working memory its not there anymore

Formal testing of amnesics

- short term/working memory intact

- long term memory deficit

- for those with RA (most do), temporally graded (eg lost last 0 yrs, but childhood memory normal) often it is quite gradual progression

- For AA, apparently cant learn anything new. In dense amnesics this deficit very severe - eg complete failure to learn animal-name association in 4 weeks of practice (Cath Haslam) - tested sever amnesics and tried to get them to learn novel associations - very rare animals - tried to train them to explicitly produce name when shown the picture, they showed pretty much zero ability to do this

- HOWEVER this is only true if conscious recollection required i.e explict memory

if try to retrive ifo implicitly, you can show that they have perfectly normal memory

- preservation of some aspects of LTM

- they have implict memory intact and skill learning intact

skill learning (procedural)

· HM learned pursuit rotor (manual tracking of moving target)

· Could learn a manual control task at the same level as normals, took him a little longer to learn, but learnt at the same level as normal

· ALSO Learned mirror drawing at same rate as normals

Week 6, Lecture - 8/8

Normal memory test - learn words of pictures, then do a variety of tests (explicit � recall, cued, old/new � amnesic performance here is poor) but then test this implicitly � repetition priming

Implicit memory intact repetition priming. Graf, Mandler and Squire (184)

Studied word list. Amnesic memory poor in three explicit tests, but normal in stem completion (CAL _______ with first word that comes to mind) à this is an important instruction “first word that comes to mind” use stopwatch to really make them thinking of first word.


- very poor at free recall

- cued recall � also very poor (cued is easier than free recall

- recognition memory test � old new - easier again � amnesics again are severely impaired at this.

- critical new test - used a test called stem completion

è test of implicit retrieval

è can add new info to LTM that can be retrieved implicitly

è memory performance for amnesics for implicit retrieval is perfectly normal

take home message can add new info to LTM for amnesics

problems with amnesics are severe, but are limited in scope - only problems with LT explicit memory

Theoretical implications

1. problems are only with LT explicit memory implicit and working memory intact

. severe AA suggests encoding/storage deficit BUT implicit tests show have been able to store new info è an explicit retrieval deficit

. again, are all memory failures retrieval deficits? Is every event that has ever happened to us actually stored? And we just cant retrieve it when we need to, this is a big call, but it could infact but true. The Korsakov Jimmie � has a very brilliant recollection of being 1, better than a normal 4 yearold, it became uncovered

Practical severe amnesics are very impaired in their day to day life, potentially if you could show this info was infact stored, it is a matter of finding out how to get it out…

Rehabilitation of memory disorders

- no success in rehabilitating lost explicit memory as a general ability (ie unable to reestablish conscious recollection

- how to help the helper - the carer � as often those with amnesia have no awareness of problems

- need to work on residual memory abilities eg. Skill based learning; or to improve use of diaries. You can learn explicitly via practice, but if you move amnesic to a new hospital and need to train them to get to the new kitchen - this is often not successful, they cant do it when trainer is not present, the learning they have achieved in very specific it doesn’t generalize very well

- often not successful

- training generalizes poorly (find room ok with trainer present, but not alone)

- forget to look at diary

Why cant they do this? To improve their everyday life??

- ONE REASON � without explcit memory we have difficulty learning from our mistakes. We can consciously remember when something we did last time led to the wrong conclusion. Tend to strengthen previous erroneous response

- Errorless learning Baddeley and Wilson (14)

- train patient to learn something, so that they never make a mistake

- suggested implicit learning intact, leads to repeating same error

- how do we achive this

è don’t let an error ever occur

è give complete answer at first and gradually fade out cues

è also called method of fading cues

every morning I must look at my diary

every morning I must look at my ______

every morning I must look ________


è this is hard work


“Accuracy/distortion” focus on LTM

if we do produce a memory, is it necessarily accurate, it is a distortion more often than a complete fabrication. Back to talking about conscious recollection. There is a heap of evidence that when you are confident etc, then this does not necessarily mean that this is exactly what happened

(1) context/schema/gist effects � memory you produce depends on context it was placed or based on some sort of schema (plan or list of standard things you expect to happen in a given circumstance)

- Bartlett (1) reconstructive memory - war of the ghosts story - asked oxford undergraduates � native American tribe story about religious beliefs etc. read them them story, later told them to retell sotry back to them, people tended to report back information that was more inline with their beliefs or the beliefs they held about what native Americans believed (stereotypes)

- Pompi and Lachman (167) � repeating back a story that you had heard, found a lot of recognition errors, thematic errors in prose recognition “chief resident jones” è no mention of the word doctor or surgeon they often said surgeon was explcitily stated and although it was implied it wasn’t actually said. Also “ugly growth too large for removal” this was interpreted as cancer by subjects. Don’t remember exact copy of what occured

- our lab

remember meaning not form

example of distortion from context

Week 7 - Lecture 1

False Memory

Accuracy/distortion focus on LTM

If we do produce a memory is it necessarily accurate?

() source monitoring - actually heard word? Or imagined it being said?

- Unconscious plagiarism

- forgetting who told you the gossip

Johnson, Foley (188)

Expt1 ss heard some words said by experimenter and imagined themselves saying the words

è good at discriminating whether they had heard word or imagined word

è not very many source monitoring errors when you are imagining yourself saying the words

expt ss heard the same words (1/) by experimenter and imagined the experimenter saying the other half of the words

è very poor heard/imagined discrimination at test

è source monitoring effects, confusion in source when you imagine experimenter saying words

è internal vs external

More recent source monitoring experiments

à Rodiger - looked at discrimination b/w imagining self doing something and actually doing something.

à Delay is often quite lengthy in source monitoring experiments

à They were brought back a week later and showed complete confusion

à 60% false memories, thought they had done what theyhad only imagined themselves doing

à equally likely � as many false responses as correct responses

7. Eyewitness Testimony (also in text book)

Misinformation paradigm ( phases) expt 174

1. video or slides of events � imagined crime, car accident etc, attention grabbing event, which mimics you being there

. given verbal description of event or asked questions in verbal form regarding event � which contains conflicting info or leading questions � some of which disagrees with the original event.

. then take a memory test of originianl event

can you overcome this “false info” given in stage to reproduce correct event occurecnes from stage 1.

Loftus and Palmer (174) - misinformation paradigm

- saw film of car accident

- after video had to estimate speed when cars (CONTACT, HIT, BUMPED COLLIDDED OR SMASHED) into each other.

- Neutral condition � how fast when ACCIDENT occurred?

- Not neutral conditions

o Contacted � not fast

o Hit � a bit faster

o Bumped

o Collided � faster

o Smashed - FAST

When asked to rate speed è if given leading question these estimates were higher with FASTER VERBS

All saw the same accident, the way question was asked ifluenced their response.

1 week later - did you see broken glass at the accident??


Those who had been given leading verb SMASHED � were much more likely to report broken glass

Memory is inaccurate but can also be distorted by subsequent events.

4. crimes and eyewitness testimony

see text

how reliable is eyewitness testimony in

- lineups

- crime situation � courtroom

- juries

juries/courtroom take eyewitness testimony as very powerful � this is not a good idea, memory fails!!

Perhaps these experiments are too dull

Perhaps the event needs to be more emotional, to take all of attention è and hence they will be easier to remember, more accurate.

5. flash bulb memories

- where were you when president kennedy was shot?

- Princess dianas death

- Port artur massacre

- Sept 11

Emotional response in these events (for all people) is very strong

But also look at personal events � such as car accidents or rape.

core components

1. very high level of emotional response to event

. months/years later still know where you were and can “see event” highly confident of what happened in that event

Brown Kulik (177) proposed flashbulb memories have special status

- they are an exact detailed copy (i.e accurate)

- they are resistant to forgetting

they hypothesized

ss highly confident è cant doubt a flashbulb memory, however this doesn’t mean you remember it correctly just because you are confident


We realy on anecdotal stories

Don Thompson rape case - confusion of identity of assiliant with face on tv at the same time. Identified Don Thompson as rapist, but she had tv on at time of raping and he was being interviewed by the BBC � she confused source in her own mind.

Space Shuttle challenger esplosion (186)

McCloskey et al (188)

Immediate description of events (-7 days after) and then a re test after a month delay

1. do people describe it as a flash bulb memory? YES

. do we lose info and false memories occur after months - see handout of questions asked

McCloskey et al (188)

Immediate description � correct

Almost all report as flashbulb events and are highly confident - months later (6.1/7 confidence)

Definitely a flash bulb memory

· but several reports were quite inconsistent from -7 days to months

· see handout table

· particularly if more detail is assessed

· testing for REAL detail is assessed

· story on handout

à even though memory looked good for general

à when looking at detail errors seem to be occurring as stories conflict with one another

Regan Assination attempt

- tested 5 yrs and 5 yrs months after event

- even original memory might be different to at 5 years - interested in changes

- for inaccurate detail produced in first test, belief increased in second test

inaccurate and inconsistent � b/w 5 yrs / 5 yrs months

memory is becoming more specific - but more consistent and inaccurate

flashbulb memories can still result in false memories not necessarily accurate in detail
