  1. THE STIMULUS PERSPECTIVE    The
  2. Empiricist and Gestalt theories
  3. assume that the stimulus the
  4. eye receives is inadequate,
  5. ambiguous, or impoverished 
  6. and thus cannot provide an
  7. adequate explanation of our
  8. perceptions. However,
  9. researchers working in the
  10. psychophysical tradition, the
  11. third major theoretical
  12. perspective, argue that all the
  13. information necessary to
  14. explain our perceptions is
  15. present in the environment,
  16. waiting to be picked up by the
  17. moving eye of the observer. For
  18. each type of perceptionΓÇöΓÇô
  19. whether it be of color, shape,
  20. size, depth, motion, or 
  21. whatever elseΓÇöΓÇôthere is a unique
  22. stimulus or type of stimulus
  23. information. Thus there is no
  24. need to postulate such
  25. mechanisms as unconscious
  26. inference or spontaneous
  27. neural interaction to explain
  28. perception.
