Procedure: The participants were given one schema at the encoding stage and one schema at the retrieval stage, to see if they were influenced. In a later study, Anderson and Pichert () presented evidence for the effect of reader perspective on retrieval processes. Subjects who shifted to the alternate. Key Study: Anderson and Pichert () Aim: To investigate if schema processing influences both encoding and retrievalMethod: Highly controlled l.

Anderson and Pichert 1978
Terminology in the story was not technical, any less familiar terms were znd in nontechnical language. Subjects were then told that people can sometimes remember information that they thought they had forgotten if they were given a new perspective with which to think about the information.
However, when editing is considered, it appears that a general context at encoding is more facilitating for the expert. The editing performance of the novice does not vary between conditions.
Anderson and Pichert ()
Knowledge can be represented as hierarchical, with highly inclusive concepts subsuming more specific information. The hypothesis is supported if the expert includes more idea units in the second recall which were not in the first recall than does the novice. The expert will better be able to provide information important to the situation if allowed to encode with a general schema, than if asked to use different specific schema.
A further study demonstrating schematic influence is by French and Richards Human Learning and Memory, 7, They have been to one meeting, and they like the people in the club very much, but they noticed that everyone has a trendy, stylish bike. Examine one evolutionary expla French and Richards explained this result in terms of schematic knowledge of roman numerals affecting memory retrieval. Therefore, it does not explain how new information is organised in early life E.

The product information was presented as though it was being seen in a bicycle shop. Reading time varied between 1. There were four different types of bicycles mentioned in the story that fall into two general usage contexts; image related and functional. Participants’ schema of an office influenced their memory of it.

The results of a series of studies examining chess experts by Chase and Simon caused a shift in focus from the differences in search strategies as a source of expertise to the differences in the quantity, content and organization of localized knowledge. They are mental representations of categories from our knowledge, beliefs and expectations about particular aspects of the world such as people, objects, events, and situations. The first hypothesis states that experts edit more than novices.
Consequently, the expert will have a more comprehensive schema for the domain when compared to the novice. This supports the retrieval hypothesis. Anderson, Pichert and Shirey offer three mechanisms responsible for this effect. This supports the first portion of hypothesis two. The best study guides. There is no difference in the editing performance of the novice between encoding and retrieval conditions. The subjective measure of expertise was taken as an indication of the amount of information the subject held with respect to bicycles on a ten point scale anchored with novice and expert.
There are four dependent variables.
The information recalled with the first perspective is interpreted as an indication of encoding effects. The designation of importance occurs at retrieval, this is clear because the edited information is important to the second retrieval context, and not to the first retrieval context.
Support for the encoding hypothesis is offered by Chiesi, Spilich and Voss They did not recall the wine and picnic basket that were in the office. Explain how biological factors Each idea unit was rated on a five point scale anchored with not at all important and very important.
The processes do not act independently, there is evidence of an interaction between encoding and retrieval processes. Thus, less information will be recalled Cowley Unit 2 – Cognitive psychology Other.
The information edited by the expert will be important to the second retrieval context. They are going shopping for a new bike. In summary, there are three ways that schemas may affect the encoding of information; by directing attention, by providing a scaffolding and by encouraging inferential elaboration.
The difference in editing between context and no context conditions supports the interaction hypothesis in the case of the expert. Evidence in cognitive psychology suggests that the processes are not independent.
There is also evidence of an interaction between the encoding and retrieval; encoding specificity for example. Strength of schema theory — there is many types of research evidence to support it.
