Schema Theory (Lvl3)

Possible slots in schemas

May be filled with unchangeable information

May contain generalizations

May not be constantly filled

Schemas can mesh together and may interlink to form one great big mindmap of information

Schemas are often generalizations and may contain many stereotypes about what a person sees

Schemas are not constant and are constantly changing and adapting

Assimilation

The use of a previously generated schema in a new situation and context

Accomodation

When new information is added to old schemas so the information is rearranged

Aim

To investigate whether or not shemas affect both encoding and retrieval

Design

Independent groups

Procedure

Participants were given one schema at the retrieval stage and another at the encoding stage.
Participants were initailly told a story about two boys who skip school and go to one of their houses because it is empty on Thursdays. The house was isolated and under-kept. The story contained 72 memory points.

Half of the participants were instructed to read the story as burglars, the other half as prospective buyers. Participants were distracted for 17 minutes adn then either changed perspective or kept the same one.

Results

Participants in the changed schema group recalled 7% more points on the second recall test compared to the first.

Evaluation

The results of the experiment indicate that schema processing must have some effect at retrieval as well as at encoding, because the new schema could only have influenced recall at the retrieval stage.

Organizes knowledge into subcategories

Facilitates our ability to freely recall information

Simplifies our understanding of our surroundings

Allows us to predict how people will react and what to expect

Aim

To investigate the effects of an individual's schema on recall

Design

Repeated measures

Participants

English males that did not know Native American folklore

Procedure

Participants were asked to read a Native American folk story. They were then asked to recall the story at various intervals of time after having read it.

Results

After recalling the story many times, the story had been significantly shortened

Vocabulary that was unfamiliar to the non-natives was changed to something they could more easily recall (e.g. canoe to boat)

Evaluation

Particioants changed the story and adapted it to fit into their schemas. This demonstrated that cognitive memory is affected by what we already know.

Aim

To investigate how an individual's schemas affect their memory of office items

Method

Participants were asked to wait in an office for 35 seconds. After they left, they were asked to recall what they had seen in the office

Results

Items that would normally be in an office were easily recalled, but objects less common in an office were not remembered. Some participants falsley recalled seeing somehting in the office that might normally be there, but was not.

Strengths

Supports the theory that memory is reconstructive

Explains various cognitive processes

Weaknesses

The theory is vague and underdeveloped

Does not explain the formation of schemas

A network of knowledge that gives us expectations of how the world works
