11. Can be perceived as two different things depending on how you look at them






12. Is the tendency to complete incomplete figures

14. The feeling that results from physical stimulation






15. Is the tendency to make figures out of symmetrical images






16. Rightly stating that no stimulus exists

22. Correctly sensing a stimulus






23. Refers to the relationship between the meaningful part of a picture and the background






24. Has been called the most important depth cue. Our eyes view objects from two slightly different angles - which allows us to create a 3-dimensional figure






25. Comes from the complexity of the sound wave






26. Saying you detect a stimulus that is not there






27. The clear protective coating on the outside of the eye






28. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green






29. The center of the retina; has the greatest visual acuity






30. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






31. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'

43. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes






44. Found that infants prefer relatively complex and sensational displays






45. Developed the visual cliff to study whether depth perception was innate

49. Is the inability to recognize faces






50. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.
