Sensory and perception are often confused or used interchangeably by. Perceptual adaptation is the process in which we take in that sensory information and our minds fill in the blanks with memories. In a recent series of experiments, McGann was interested in looking at cognitive processing at the earliest stages of perception at the level of sensory neurons themselves. Sensory adaptation is the process of filtering out, or getting used to, certain sensory information that our brains deem to be irrelevant. Visual perception Perception obtained through the sense of vision. McGann, a professor of psychology at Rutgers University, uses the olfactory system as a model to investigate neural processing of sensory stimuli. The effect is then of extremely short duration (less than 200 ms). exposure of 40 ms duration masked by another stimulus), unconsciously arouse perception. subliminal) may, in rare circumstances (e.g. Subliminal perception Stimuli below the threshold of sensation (i.e. Loss of light perception represents blindness. It is affected by context (figureground) and intensity, duration. (LP) Term used to indicate a barely seeing eye that can just see light but not the form of objects. Typically, perception includes recognizing features and relationships among features.

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. 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. Most important is the existence on the two retinae of different images of the same object (called binocular disparity or retinal disparity). Many factors contribute to depth perception. Our ability to judge the latter is much more precise than for the former.

Thus one recognizes the shape, colour, location and differentiation of an object from its background. The mental process of recognizing and interpreting an object through one or more of the senses stimulated by a physical object.
