CORE DEFINITION

A cognitive strategy that groups individual items into meaningful higher-order units, allowing a fixed number of working memory slots to hold far more information. Miller's finding that working memory holds roughly seven items, plus or minus two, describes slots rather than content, so a chunk can carry many elements. The key qualification is that the grouping must be meaningful: arbitrary grouping adds load rather than reducing it. Expertise consists largely of possessing many domain-specific chunks in long-term memory.

SCAFFOLDING EFFECT

Reduce cognitive load

- Item recognition: identify the scattered pieces that must be held or processed. - Meaningful grouping: combine items by pattern, category, or existing schema. - Chunk growth: enlarge and complicate the chunks as familiarity increases.

Working memory is limited by the number of units it can hold rather than by the amount of information each unit contains. Grouping elements into a single meaningful unit therefore increases the total information retained without exceeding the slot limit. Meaning matters because the grouping must be retrievable: an arbitrary bundle has to be reconstructed each time, whereas a familiar pattern is recalled as one item.

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 …
