Definitions:

Parallel Processing

The ability of the brain to simultaneously process incoming stimuli of differing quality, a concept crucial to understanding how humans can perform multiple tasks at once.

Perceptual Constancy

The brain's ability to perceive objects as unchanging despite changes in sensory input, such as changes in illumination, angle of viewing, or distance.

Proximal Stimuli

The stimuli that interact with sensory receptors, directly influencing perception.

Distal Stimuli

Objects or events in the external world that provide information to the sensory organs, leading to perception.
