Document Summary
Perception conscious experience that results from stimulation of the senses. Begins with stimuli in the environment and ends with the behavioural responses/conscious experiences of perceiving, recognizing, and taking action.

When perception or recognition leads to action, that action could change perception and recognition.

Perception identified with complex processes that involve higher-order mechanisms such as interpretation and memory that involve activity in the brain. Sensation involves detecting elementary properties of a stimulus and perception involves the higher brain functions involved in interpreting events and objects. Distal and proximal stimuli (steps 1 and 2) Stimuli in the environment reach receptors in the eye.
