The role of schema in behaviour and/or cognition.

## Learning objectives

- The role of schema in behaviour and/or cognition.

## Core concept

A schema is a mental framework of prior knowledge that organises information and guides how we act, interpret and remember. In behaviour, schemas work as scripts — expected sequences (a visit to the doctor, a restaurant) that tell us what to do and expect. In cognition, the same frameworks make processing efficient by filling gaps with what usually happens, but that gap-filling distorts memory: we recall schema-consistent details that were never there and overlook inconsistent ones. So memory is partly reconstructive, shaped by what we already know.

## Key studies

IB Psychology answers must be supported by named studies. Learn these to cite as evidence:

**Bower, Black, and Turner (1979)** — Recalling a text about a routine event, people added script-consistent details that were not in the original passage. — *Shows schemas as scripts — guiding behavioural expectations and inserting information during recall.*

**Brewer and Treyens (1981)** — After briefly waiting in an office, people recalled schema-consistent items better and 'remembered' expected items (e.g. books) that were absent. — *Demonstrates schema-driven reconstruction of memory — prior frameworks shape what is remembered.*

## Evaluation (AO3)

**Strength — explains efficiency and error together** — One idea accounts for both fast, gap-filling understanding of everyday situations and predictable memory distortions, and it has broad reach across behaviour and cognition.

**Limitation — vague construct** — 'Schema' is hard to define and measure precisely, so the theory describes the effects better than it specifies the mechanism that produces them.

## Scope

> **note**
>
> Schema's role across behaviour and memory is the focus. The theory body is COG_8; decision-making models are COG_6; culturally specific schemas/memory strategies are LC_8.

## Common pitfalls

- **Wrong:** Using schema theory to answer a 'thinking and decision-making' question, or confusing schema processing with Piaget's assimilation.
  - Why it fails: A frequently penalised misconception in IB Psychology exams.
  - Correct: Schema theory is about how prior knowledge organises encoding/reconstruction of memory and guides behaviour — it is not the dual-processing model of decision-making, and schema processing is not the same as assimilation.
