Definitions:

Temporal Cortex

Part of the cerebral cortex involved in processing auditory information and encoding memory.

Unconscious Inference

A process postulated by Hermann von Helmholtz to explain certain perceptual phenomena such as size constancy. For example, an object is perceived to be at a certain distance and this is unconsciously taken into account in assessing its retinal image size, with the result that size constancy is maintained.

Size Constancy

The perceptual understanding that an object's size remains the same despite changes in the distance from which it is observed.

Perceptual Constancy

The brain's ability to recognize that an object's characteristics remain the same despite changes in the sensory input, such as distance or lighting.
