INTRODUCTION

English translation pending.

CORE DEFINITION

Developed by Jean Piaget and elaborated by later cognitive psychologists such as Frederic Bartlett and David Rumelhart. A schema is an organized knowledge structure that represents what a person expects about a category, situation, or sequence of events. Schemas guide attention, fill gaps during comprehension, and speed retrieval, but they also cause people to remember what fits the schema rather than what was actually present. Piaget described development as assimilation of new information into existing schemas and accommodation when a schema must be revised.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Prior activation: surface what the learner already expects before presenting new material. - Expectation audit: check which parts of your reading come from the text and which from the schema. - Revision trigger: treat contradictory evidence as a signal to accommodate rather than to force-fit.

Anchor fast decisions

A schema supplies a template with slots, so incoming information is matched against expectations rather than processed from scratch. Matching is fast and cheap, which is why experts recognize patterns instantly, but the same shortcut fills missing details with defaults and quietly reshapes ambiguous input. The result is comprehension that is efficient and partly self-confirming.
