Relating to the process of perception; concerning how sensory information is organized, interpreted, and consciously experienced. Involves the mental processing of sensory input.
From Latin 'perceptus' (perceived, understood) from 'percipere' (to seize completely, understand) composed of 'per-' (thoroughly) and 'capere' (to take, seize) plus '-al.'
