Definitions:

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.

Neural Synchrony

The simultaneous firing of neurons in different parts of the brain, which is believed to be crucial for various cognitive functions, including attention and perception.
