CORE DEFINITION

Despite changes in external stimuli (light, angle, distance), we can still stably recognize the size, color, and shape of objects.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Perceptual stability mechanism. Explains why distant people do not appear smaller—the brain automatically compensates.

Anchor fast decisions

Although the retinal image changes with distance, angle, and lighting, the brain automatically compensates based on depth cues, context, and prior knowledge, maintaining stable perception of object size, shape, and color (size/shape/color constancy). It is the core mechanism of perceptual stability.

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.
