percept:  [1] A mental impression of something perceived by the senses,
viewed as the basic component in the formation of concepts.


 [2] A percept is the resultant of perceiving. It is the representation of an external event that affected the senses and which - by perceptual processing - caused the activation of a certain category in the mind, i.e., the percept.


 [3] What the perceiver sees or hears as a result of stimulation, as opposed to the physical reality of the stimulation. The percept may be considered the "object" of study in perceptual psychology.


"When you drop a pebble into a pond, it makes a ripple. At first the ripple is only small,
but eventually it grows to cross the whole pond."
