How does memory work?
Memory can be defined as: - the capacity to encode, store and retrieve information.There are many theories of memory that explain how we receive information, process it and store it. Some theories focus on the different types of memory stores, such as; sensory short-term and long-term, and others focus on where the different types of memories are stored, such as; imagery, procedural and declarative.It can be difficult to study where our memories are stored in the brain, as we can’t always see it. However, advances in technology (PET, MRI scans) have allowed us over to see which parts of the brain are active during memory recall tasks.
Cognitive Approach
Bartletts’ War of the Ghosts
One night two young men from Egulacwent down to the river to hunt seals, and while they were there it became foggy and calm. Then they heard war-cries, and they thought: "Maybe this is a war-party". They escaped to the shore, and hid behind a log. Now canoes came up, and they heard the noise of paddles, and saw one canoe coming up to them. There were five men m the canoe, and they said: "What do you think? We wish to take you along. We are going up the river to make war on the people". One of the young men said: "I have no arrows". "Arrows are in the canoe", they said. "I will not go along. I might be killed. My relatives do not know where I have gone. But you", he said, turning to the other, "may go with them." So one of the young men went, but the other returned home. And the warriors went on up the river to a town on the other side of Kalama. The people came down to the water, and they began to fight, and manywere killed. But presently the young man heard one of the warriors say: "Quick, let us go home:that Indian has been hit". Now he thought: "Oh, they are ghosts". He did not feel sick, but they said he had been shot. So the canoes went back to Egulac, and the young man went ashore to his house, and made a fire. And he told everybody and said: " Behold I accompanied the ghosts, and we went to fight. Many of our fellows were killed, and many of those who attacked us were killed. They said I was hit, and I did not feel sick". He told it all, and then he became quiet. When the sun rose he fell down. Something black came out of his
mouth. His face became contorted. The people jumped up and cried. He was dead.

EXPERIMENT 2
6. Procedure for experiment 2
The second experiment was to provide additional insights into the origin of the different speed estimates. In particular they wanted to find out if the participant’s memories really had been distorted by the verbal label . A similar procedure was used whereby 150 student participants viewed a short (one minute) film which contained a 4 second scene of a multiple car accident, and were then questioned about it. There were three conditions and the independent variable was manipulated by the wording of the question. 50 of the participants were asked 'How fast were the cars going when they hit each other?’ 50 of the participants were asked 'How fast were the cars going when they smashed into each other?' 50 of the participants were not interrogated about the speed of the vehicles. One week later, the participants returned and, without viewing the film again, they answered a series of questions about the accident. The critical question was 'Did you see any broken glass?' The critical question was part of a longer series of questions and was placed in a random position on each participants question paper. There was in fact no broken glass in the film.

6. Results for experiment 2
RESPONSE BIAS FACTORS MEMORY DISTORTION
The memory of how fast the cars were travelling could have been distorted by the verbal label which had been used to characterise the intensity of the crash.
The participant is not sure of the exact speed and therefore adjusts his or her estimate to fit in with the expectations of the questioner. (This is also an example of a demand characteristic)
Note that the researchers were not interested in the response to this
question. Rather, the researchers were attempting to find out if the wording of the
question would distort the participants’ memory of the car crash.
The participants who were not asked about the speed of the vehicles were the control group. A control group is used by researchers as a comparison. The control group experiences all the same conditions of the study in the same way as the experimental group or groups with the exception of the independent variable. Therefore by comparing the results of the experimental groups and control group the effects of the independent variable can be observed.

development of Autism?

Symptoms in all these areas appear before 36 months of age and some people with autism have additional cognitive difficulties and many are intellectually impaired. Some people with autism have exceptional gifts, termed islets of ability, in one particular area, such as music or art. In most cases autism is a life-long condition, although the patterns of difficulties may change or become less severe as children grow up.
The term autism is now used as a general term to describe a wide spectrum of disorders from Asperger syndrome at one end through to individuals showing severe forms of autism at the other extreme.

THEORY OF MIND√
√

Previous research: Describe the Sally Anne Test
Why would this test be inappropriate for adults with autism?
The exact cause of autism is as yet not known but most research shows that genetic factors are important. It is also evident from research that autism may be associated with a variety of conditions affecting brain development which occur before, during, or very soon after birth. Interestingly the authors of this study note that earlier research had found that parents of children with Asperger syndrome do worse on the eye task described in this research than matched controls suggesting that theory of mind deficiencies are in fact inherited.

On the day of the final battle, which will decide the outcome of the war, there is a heavy fog over the mountains where the fighting is about to occur. Low-lying clouds hang above the soldiers. By the end of the day the Blue army have won. Q: Why did the Blue army win?

Autistic subjects were compared to two groups of adults, one who were 'normal' and one who had [?] The
[?]in this study was the three different groups of subjects, while the [?] was performance on an advanced test of theory of mind (eyes task). The independent variable varied naturally and was not manipulated so the method used
was a [?] The eyes task consisted of magazine photographs of [?] different faces and each photo was shown
for [?] seconds. Subjects were asked to choose between two mental state terms printed under each photo. Subjects in the two
clinical groups were also tested using Happe's strange [?]. This was to check for [?] validity meaning that the two measures should produce similar results.The results from the eyes task show that subjects with tourette's syndrome did not differ
from normal subjects but both control groups performed significantly [?] than the group with autism. Subjects with autism were
[?] impaired on the Happe's strange stories task compared to the control groups. It was concluded that the core deficit involved in autism is the lack of an advanced theory of mind.

How were the chimps reared and exposed to the lexigrams?Kanzi was first exposed to the use of symbols, gestures and human speech at the age of 6 months as he watched the interactions between his mother (Matata) and her keepers. Kanzi remained with Matata constantly until he was two and a half years old, and during that time attempts were made to teach Matata symbols. Importantly, no attempts were made to teach Kanzi symbols directly. Although Kanzi was allowed to observe Matata’s training sessions, he was generally kept otherwise occupied as he tended to distract Matata’s attention. Beginning at one and a half years of age Kanzi did show an interest in symbols. For example he would light keys sporadically and then run towards the vending devise suggesting that he had learned that touching symbols caused this devise to dispense food. Although Kanzi did not engage in any behaviours that suggested that he knew that specific symbols were associated with specific foods Kanzi also spontaneously began to use the chase lexigram to initiate chase games. This behaviour appeared shortly after he spontaneously began to use a gesture (hand clapping) for the same purpose. Kanzi was separated from his mother Matata at two and a half years so that she could take part in a breeding programme. When she returned four months later Kanzi had developed a preference for human company even though he was allowed to be with his mother as much as he liked. Kanzi’s sister Mulika was born nine months later and Kanzi enjoyed spending time with her. At four months of age Mulika developed an eye infection and was taken away for treatment. When she

Cognitive Approach
returned she also chose to stay with human companions most of the time. Mulika did not have the opportunity to observe Matata during symbol training but she did observe Kanzi using symbols.
The rearing environment of Kanzi and Mulika was similar to that of Sherman and Austin following their separation from Matata. For example, they were with people who use the visual symbol system around them throughout the day for a wide variety of communication and a number of the same teachers have worked with all 5 animals (Sherman, Austin, Matata, Kanzi and Mulika).
What were three differences between the chimps in terms of their environments and exposure to the lexigrams?1.2.3.
Mind-map the key descriptions of Mind-map the key descriptions ofthe naturalistic outdoor environment. the indoor environment.
Instead of formal training, people modelled symbol
use during their communications with each other
and around Kanzi and Mulika. During all daily activities (playing, eating, resting, travelling in woods, etc.) people commented on their activities
both verbally and visually by pointing to an appropriate lexigram on a keyboard. For example, if
they were engaged in a tickling bout, the teacher
would comment "(teacher's name) tickle Kanzi"
No formal training was ever attempted with Kanzi and Mulika
and food was never made contingent on symbol acquisition
because they could (a) use symbols without specific training, (b) identify
symbols regardless of location, (c)
did not tend to confuse symbols for similar items (such as apple, orange
and banana), and (d)

Tests used to demonstrate symbol understanding:Kanzi and Mulika were tested informally, in everyday situations. For example, If Kanzi was playing with some keys he may have been asked what they were. Importantly though, such tests were not used as drills, nor were they associated with rewards. Furthermore, these informal tests were only used with lexigrams that Kanzi and Mulika knew.
Kanzi & Mulika were also tested using a series of formal tests:

Formal tests:
Even though the formal tests were novel to Kanzi and Mulika they did well on these tests from the start. They seemed to understand that the experimenters were not communicating about something that was going to happen as they touched a symbol but rather were posing a specific question. Kanzi's and Mulika's could select lexigrams in response to the spoken English word, select photographs in response to the spoken English word, and select photographs when shown lexigrams.
- At the time these tests were given to Mulika, it was thought that she knew only a few lexigrams well enough to accurately select them out of context in a formal test. However, her test results quickly revealed that her capacities had been underestimated and illustrated that she knew 42 symbols, a number of which she had not yet used herself.
- Kanzi did have some difficulties when the word was produced by a synthesiser although even the researchers found it difficult understanding some of these words.
Cognitive Approach
- When Sherman and Austin were tested they were initially confused because they anticipated that, when they identified an object, they would then get the object (e.g. a banana).
- Sherman and Austin were able to select the correct photograph when shown the lexigram; however, their performance dropped to chance when they were asked to select the correct photograph in response to a spoken English word.
- They also seemed not to like these trials and attempted to avoid them by requesting to go elsewhere; and at times, they refused to respond. Both Sherman and Austin repeatedly scratched themselves over their entire bodies (a behaviour that signals frustration in chimpanzees) during English trials, but not at all during lexigram trials.

General observations of symbol usage:
K & M were able to make generalisations beyond the specific meaning of the symbol, e.g. Kanzi used ‘tomato’ to refer to other small red fruit.
Kanzi used symbols in different ways depending on the situation, e.g. ‘juice’ was used as a food name and for tree house – where juice was usually kept.
Kanzi took the lexigram by himself to go off and practice and would cover himself with a blanket.
