perception

The reception, selection, organization and interpretation of sensory data. Perception is greatly influenced by previous experience and the stored data accumulated from such experience.

perception 

The mental process of recognizing and interpreting an object through one or more of the senses stimulated by a physical object. Thus one recognizes the shape, colour, location and differentiation of an object from its background. See sensation; visual integration.
anorthoscopic perception See anorthoscope.
binocular perception Perception obtained through simultaneous use of both eyes.
contour perception See contour.
depth perception Perception of the distance of an object from the observer (absolute distance) or of the distance between two objects (relative distance). Our ability to judge the latter is much more precise than for the former. Many factors contribute to depth perception. Most important is the existence on the two retinae of different images of the same object (called binocular disparity or retinal disparity). There are also many other contributing factors, such as the characteristics of the stimulus (called cues), binocular parallax and, to a smaller extent, the muscular proprioceptive information due to the efforts of accommodation and convergence. Depth perception is more precise in binocular vision but is possible in monocular vision using the following cues: interposition (superposition), relative position, relative size, linear perspective, textural gradient, aerial perspective, light and shade, shadow and motion parallax (Fig. P6). Syn. spatial vision. See stereoscopic visual acuity; visual binocular cliff cell; moon illusion; aerial perspective; linear perspective; relief; Ames room; leaf room; stereopsis.
dermo-optical perception See extrasensory perception.
extrasensory perception Perception obtained by means other than through the ordinary senses as, for example, telepathy (mind reading) or reading by moving a finger over a printed text (dermo-optical perception).
light p . (LP) Term used to indicate a barely seeing eye that can just see light but not the form of objects. Loss of light perception represents blindness.
subliminal perception Stimuli below the threshold of sensation (i.e. subliminal) may, in rare circumstances (e.g. exposure of 40 ms duration masked by another stimulus), unconsciously arouse perception. The effect is then of extremely short duration (less than 200 ms).
visual perception Perception obtained through the sense of vision.
