Glanzer and Cunitz showed that when participants are presented with a list of words, they tend to remember the first few and last few words and are more likely to forget those in the middle of the list, i. Information passes from store to store in a linear way. Cognitive processes include perception, attention, language, memory and thinking. This was the original H. Episodic memory is a part of the long-term memory responsible for storing information about events i. However, their procedural memory appears to be largely unaffected.

The witness is asked to describe the scene in a different chronological order e. The phonological loop plays a key role in the development of reading. One group did this on the beach and the other group underwater. This was the first study to use MRI to look at the damage to H. In this situation, retrieval cues are absent and the likely result is cue-dependent forgetting.

They can recall skills they have already learned e. Triangulating evidence The cases of Clive Wearing and H. Forgetting is greatest when context and state are very different at encoding and retrieval.

Each store has its own characteristics in terms of encoding, capacity and duration. With the study guides and notes written by fellow students, you are guaranteed to be properly prepared for your exams.

If any information is not important then it decays or disappears. The effects are stronger when the participants are in a positive mood than a negative mood.

KF – Shallice and Warrington – Unit 2 – Cognitive psychology – Stuvia

Words early on in the list were put into long term memory primacy effect because the person has time to rehearse the word, and words from the end went into short term memory recency effect. Although any Level 3 command term could be asked, we’ll concentrate on the one given in the learning objective, so the question is Examine one interaction between cognition and physiology in terms of behaviour 22 You will need to plan an essay which will be about sides of A4 long, including a detailed focus on the command term.


However, a visual task and a verbal task would use different components and so could be performed with minimum errors. There are three main ways in which information can be encoded changed: Contextualising how the topic in question relates to broader debates and approaches in Psychology. And, they didn’t make any more errors in the verbal reasoning tasks as the number of digits increased.

Chandler stated that students who study similar subjects at the same time often experience interference.

KF – Shallice and Warrington 1974

For example, the Working Model of Memory proposed by Baddeley and Hitch showed that short term memory is more than just one simple unitary store and comprises different components e.

Are there any new insights that you can gain through looking at all of the results holistically? Context – external cues in the environment, e. Everything you need to know warrngton selling on Stuvia. Recall in Reverse Order The witness is asked to describe the scene in a different chronological order e. Duration refers to the period of time information can last in the memory stores.

The incident took place on a major thoroughfare in mid-afternoon.

Evidence for the distinction between declarative and procedural memory has come from research on patients with amnesia. A further problem with the study was the use of students as participants.


What students say about Stuvia. Which ones does the case criticise? Retrieval failure is where information is available in long term memory but cannot be recalled because of the absence of appropriate cues.

The main criterion is that benefits must outweigh costs. One weakness of this study was that there was an extraneous variable. A final criticism is that police personnel have to be trained and this can be expensive and time consuming. Shallce, their procedural memory appears to be largely unaffected. What relationships can you see between the three studies above?

The recall of the control group was more accurate than that of the experimental group. Although proactive and retroactive interference are reliable and robust effects, there are a number of problems with interference theory as an explanation of forgetting.

Following an operation to cure him of epilepsy, H. A different casw term requires a different style of essay, so you need to tailor what you write to the question. If a weapon is used to threaten a victim, their attention is likely to focus on it. Cognitive processes include perception, attention, language, memory and thinking.
