some information about PERCEPTION.

1. PERCEPTION
The ability to see, hear, or become aware
of something through the senses.

2. • Perception is the organization, identification, and
interpretation of sensory information in order to represent
and understand the environment.
• All perception involves signals in the nervous system,
which in turn result from physical or chemical stimulation
of the sense organs.
• For example, vision involves light striking the retina of the
eye, smell is mediated by odor molecules, and hearing
involves pressure waves. Perception is not the passive
receipt of these signals, but is shaped by learning,
memory, expectation, and attention.
