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.

However, the novice also edits based on importance. This suggests that although the processes active at retrieval are somewhat influential see hypothesis onethe processes active during encoding do not affect what is recalled.
The information recalled with the other perspective is interpreted as an indication of retrieval effects.
The expert provides 2. Participants then heard a story which was based on 72 points, previously rated by a group of people based on their importance to a potential house-buyer leaky roof, damp basement or a burglar 10speed bike, colour TV.

aanderson Encoding is manipulated between subjects. The group who kept the same schema did not recall as many ideas in the second testing.
The context condition is a replication of the procedure used in Anderson and Pichert which manipulates retrieval within subjects. Evidence in cognitive psychology suggests that the processes are not independent. The product information was presented as though it was being seen in a bicycle shop.

Editing provides evidence of the influence of the processes active at retrieval the retrieval explanation. There were four different types of bicycles mentioned in the story that fall into two general usage contexts; image related and functional.
Idea andersln unrelated to those in the story are not included in this analysis. Anderson and Pichert found that when subjects were given a perspective at encoding and then given a new perspective at the time of the second recall, they remembered 7.
Alternatively, research in cognitive psychology emphasizes the interaction between encoding andersoon retrieval as critical in determining what information is recalled Craik and Lockhart ; Tulving ; Tulving and Anc Familiarity was measured on a ten point scale anchored with novice and expert. Discuss the use of compliance Tulving, Endel and Donald M.
Consequently, this study replicates pichret results reported by Anderson and Pichert Schema theory provides the theoretical basis for the studies reported below. Terminology in the story was not technical, any less familiar terms were explained in nontechnical language. Anderson and Pichert demonstrate support of the retrieval hypothesis.
The experience measure was a self report measure of how often the subject rides a bicycle as indicated on a ten point scale anchored with never and very often.
Anderson and Pichert ()
Half of the pichdrt were asked to read the story for the point of view of a house-buyer and the other half from the point of view of a burglar. The participants heard a story that was based on 72 points. Schema theory does not show how schemas are required. 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 andd compared to experts.
Define strengths of schema theory: They were asked to recall all of the information again. Following the first recall task subjects spent five minutes working at the Surface Development Test French, Ekstrom and Price which requires that subjects mentally “fold” a two-dimensional figure to match a three-dimensional representation.
IB Guides why fail? They are going anderso for a new bike. Examine one evolutionary expla They are also concerned for their safety on the street. They were asked to think back to the original story with the following context in mind, they were then provided with the functional usage context. Larter”The Novice and the Expert: Only experts and novices are used in this analysis, this is discussed in the Measure of Expertise section. At the time of the first recall, subjects in the no context condition were given the image related usage context, while subjects in the context condition were instructed ahd think back to the original story about the bicycle shop.
The retrieval hypothesis proposes that the schema influences processes responsible for the retrieval of the information. The first hypothesis states that experts edit andersonn than novices. The measures were standardized and summed anerson the criterion for knowledge class. To investigate if schema processing influences both encoding and retrieval.
Schema processing has an influence andefson the encoding and retrieval stage, as new schema influenced recall at the retrieval stage. In the no context condition subjects are provided usage contexts at retrieval only. With the data collected in this study it is impossible to determine whether the schema guides the search through memory or conducts the reconstruction of the original information.
However, if any of the information was incorrect, credit was not given. Participants were shown a clock with roman numerals and asked anx draw from memory.
Conversely, if information is encoded with a specific schema which assigns importance on the basis of that schema, and retrieved with a different specific schema, then changing the assignment of importance will be difficult.
Define weaknesses of schema theory: The processes do not act independently, there is evidence of an interaction between encoding and retrieval processes.
The finding that both novices and experts edit important information demonstrates that the processes active at retrieval influence what is recalled. Explain the formation of stere Participants performed a distraction task for 12 minutes, before recall was tested. The 178 will edit more if allowed to encode information with a general context, than if provided a specific context.
