CORE DEFINITION

In exemplar theory, people classify and recognise new stimuli not by applying abstract rules but by comparing them with concrete instances stored in memory and grouping them with the nearest exemplar. Its claim is that experts judge quickly and accurately because they have accumulated a large library of labelled examples, whereas novices, having few exemplars, must fall back on rules.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Recall first: when facing a new situation, retrieve similar remembered examples before reasoning from rules. - Similarity check: compare key features to decide the closest match. - Library building: deliberately accumulate labelled exemplars with outcome feedback.

Anchor fast decisions

Classification proceeds by similarity to stored concrete instances, so judgement speed and accuracy scale with the size and quality of the exemplar library. A novice lacks examples and must substitute slow rules; an expert matches immediately.

The Forgetting Curve

The Forgetting Curve is a curve used to describe the rate of forgetting in long-term memory. It was first proposed by psychologist Hermann Ebbinghaus based on his experiments conducted from 1880 to 1885. In these experiments, Ebbinghaus used meaningless letter combinations. By memorizing these combinations and checking the forgetting rate after a series of time intervals, he obtained this curve. Therefore, this curve is also called the Ebbinghaus Forgetting Curve.

Baader-Meinhof Phenomenon

The frequency illusion (also known as the Baader–Meinhof phenomenon or Red Car Theory) is a cognitive bias in which a person notices a specific concept, word, or product more frequently after recently becoming aware of it. The name "Baader–Meinhof phenomenon" was coined in 1994 by Terry Mullen in a …
