CORE DEFINITION

Perceptual load theory, from cognitive psychology, holds that when a perceptual task carries high load, irrelevant stimuli are far less likely to be processed, and when load is low, irrelevant information more readily intrudes. The core claim is that attention is a limited resource, so task load determines whether distractors get through. The theory reconciles the early versus late selection debate, and the key limit is that load, not willpower, is the gating variable.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Attention allocation explainer: predicts why a busy task feels focused and an idle one feels distractible. - Raise load, block noise: add difficulty or multi-channel demands when you must resist interference. - Lower load for insight: leave slack and white space when you need divergent ideas.

Attention is a limited resource. A high-load perceptual task consumes it fully, so distracting stimuli are filtered out before they enter processing, whereas low load leaves spare capacity and irrelevant information is processed incidentally and breaks into awareness. Load therefore decides whether selection is early or late.

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.
