In sensation, the transforming of stimulus energies into neural impulses the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment the principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount) the process of organizing and interpreting sensory information; enabling us to recognize meaningful objects and events information processing guided by higher-level mental process, as when we construct perceptions drawing out our experience and expectation the processing of several aspects of a problem simultaneously; the brain's natural mode of information processing for many functions, including vision. Contrast with the step-by-step (serial) processing of most computers and of conscious problem solving analysis that begins with the sense receptors and works up to the brain's integration of sensory information diminished sensitivity as a consequence of constant stimulation
