Question

Quizplus · Accepted Answer

Compression is the term used to describe the phenomenon where a doubling of stimulus intensity results in less than a doubling of subjective magnitude. This is because our perception of stimulus intensity does not increase linearly with physical intensity, but rather logarithmically. As a result, as the physical intensity of a stimulus increases, the perceived difference between successive increments in intensity decreases, leading to compression of subjective magnitude.
