  1. Perception
    The processes that organize information in the sensory image and interpret it as having been produced by properties of objects or events in the external, three-dimensional world.
  2. Sensation
    The process by which stimulation of a sensory receptor gives rise to neutral impulses that result in an experience, or awareness, of conditions inside or outside the body.
  3. Perceptual organization
    The processes that put sensory information together to give the perception of a coherent scene over the whole visual field.
  4. Identification and recognition
    Two ways of attaching meaning to percepts.
  5. Distal stimulus
    In the processes of perception, the physical object in the world, as contrasted with the proximal stimulus, the optical image on the retina.
  6. Proximal stimulus
    The optical image on the retina; contrasted with the distal stimulus, the physical object in the world.
  7. Psychophysics
    The study of teh correspondence between physical simulation and psychological experience.
  8. Absolute threshold
    The minimum amount of physical energy needed to produce a reliable sensory experience; operationally defined as the stimulus level at which a sensory signal is detected half the time.
  9. Psychometric function
    A graph that plots the percentage of detections of a stimulus (on the vertical axis) for each stimulus intensity (on the horizon axis).
  10. Sensory adaption
    A phenomenon in which receptor cells lose their power to respond after a period of unchanged stimulation; allows a more rapid reaction to new sources of information.
