Part 1 - How reliable is Eyewitness testimony?

The Reconstructive nature of memory - Schemas and Stereotypes

The reconstructive nature of memory is related to the schema theory. A schema is a package of memory that is organized and developed throughout our lives. Schemas are stored in long term memory.

They found out that most people put the same main aspects in their schemas.

Like schemas, stereotypes influence memory. He argued that schemas affect the retrieval process rather than the initial storage, but a study by Cohen (1981) suggested that schemas and stereotypes are important at both stages of memory: initial storage and retrieval.

The language used in questioning eyewitnesses may alter what they remember.

Loftus and Palmer (1975) showed their participants a series of projector slides of a multiple car accident. The participants then answered specific questions. It was found out that the information implicit in the question affected memory, even though the questions apparently only differed
