Psychology of Perception:

The psychology of perception is a subfield of psychology that aims to understand and explain how humans and other animals receive information about the outside world through perception and through various cognitive processes....

One cannot hope to understand the psychological aspects of perception without knowing how the physical aspects work. Sensory information from the environment, such as light or sound, must interact with the sensory organs in order for perception to be possible at all.
