Unit 2 – Cognitive psychology Other. This suggests that encoding will be facilitated with a more elaborate knowledge structure which contains more specific information. The second hypothesis states that the edited idea units provided by the experts will be important to the second retrieval cue.

The results indicated that schema processing has some effect at retrieval and encoding, because the new schema could only have influenced recall at the retrieval stage. Though the usage contexts were straight forward, and the product category is not completely unfamiliar to most students, novices are certainly less able to identify the important aspects of product information when compared to experts.

1987 the role of situation This is consistent with the work of Chiesi, Spilich and Voss The researchers found that the group of participants in the changed schema group were able to recall 7 percent more points on the second test than on the first one. If the information is then retrieved with a specific schema shopping for a trendy bike or shopping for a durable bikethe retrieved information will differ depending on what is important for a trendy bike in one instance, and what is important for a durable bike in picuert other.

Availability oichert the appropriate specific information will improve assimilation of incoming information Ausubel ; Ausubel, Robbins and Blake That they do not need anything fancy, just something durable and reliable. The study presented in this paper demonstrates that experts recall different information in different situations and the information edited by experts for a new situation is important to the that context.

Encoding, retrieval and their interaction must be considered when studying recall. The clock was left in full view of the participants and just had to draw it.

The remaining 14 idea units were irrelevant to either of the two usage contexts.

But the theory requires further research and refinements to overcome its limitations and uncover its unclear aspects. Define strengths of schema anddrson Evaluate schema theory with reference to research studies. The participants were given one schema at the encoding stage and one schema at the retrieval stage, to see if they were influenced by the last schema when they had to recall the information.

The provision of a context at encoding does not facilitate the influence of the retrieval process demonstrated by editingthis suggests that an encoding context may interfere with retrieval for the expert.

Cognition and Emotion CE1: Examine one interaction betwee They are going shopping for a new bike. There are four dependent variables. In one condition subjects encode with a context, picherf the other condition they do not.

To investigate if schema processing influences both encoding and retrieval. Consumers with different levels of prior knowledge, and therefore different degrees of elaboration in these knowledge structures, will be differentially influenced by the processes active at both encoding and retrieval.

Summary of evaluation of schema theory: As there is no evidence of the encoding explanation, there can be no evidence of an interaction between encoding and retrieval. They were asked to write down as much as they could remember from the office. The design does not annd manipulate encoding, and therefore does not test for the effects of the processes active at encoding.

There are also three ways that schemas affect retrieval; by supporting an orderly search, by aiding in the reconstruction of missing information and by providing rules for editing.

Variation in the magnitude of the influence of the retrieval processes as a result of a manipulation of the encoding condition evidences an interaction between encoding and retrieval. The difference between these consumers is the degree of product knowledge or expertise. Information we already know affects the way we interpret new information and events and how we store it in our memory.

Recovering Forgotten Information: a Study in Consumer Expertise by Elizabeth J. Cowley

Participants read a story from the perspective of either a burglar or potential home buyer. Schema theory explains how new information is categorised according to existing knowledge. Implicit in the paradigms used in the study of either the retrieval or the encoding processes, is the assumption that the processes are independent.

But it does not account for completely new information that cannot link with existing knowledge. However, when editing is considered, it appears that a general context at encoding is more facilitating for the expert.

For the expert, more elaborate schema allows them to use their prior knowledge to more deeply encode information, and to access the information later with a rich network of cues. Spiro and Mark C. The expert edits based on the importance of the information.
