Schemas are mental structures that help organize and simplify our knowledge of the world. They come from the Greek word "skhema" and were first studied by Frederic Bartlett in 1932 as part of constructive memory. Schemas are used to categorize information visually based on stereotypes of age, race, gender, and more. An activity had participants look at images of an office and a car collision then write down what they remembered to analyze how schemas influence memory. People tend to remember details that fit their schemas and sometimes fabricate details that belong in the theme.
