Sensory Adaptation

Captions available

The idea

Sensory adaptation is the reduced response of receptors to an unchanging stimulus over continued exposure.

In practice

A strong smell on entering a room becomes unnoticeable within minutes while the molecules remain present.

Where people slip

Adaptation is not habituation. One is receptor-level and automatic; the other is learned and central.
