Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Refers to how we see texture or fine detail differently from different distances






2. How we organize or experience sensations






3. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses






4. Failing to detect a present stimulus






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






6. 1. Reception 2. Sensory Transduction 3. Neural Pathways






7. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






8. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.






9. Asserts that perception and cognition are largely innate






10. Electrical impulses travel down these to the brain - where the information is understood






11. Is composed of photons and waves measured by brightness and wavelengths






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






13. The eyes are connected to the cerebral cortex by...






14. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






15. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision






16. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.






17. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.






18. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






19. Famous for the theory of color blindness






20. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






21. Found that infants prefer relatively complex and sensational displays






22. 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






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






24. The tendency to perceive a smooth motion. This explains why motion is perceived when there is none - often by the use of flashing lights or rapidly shown still-fram pictures - such as in the perception of cartoons. This is apparent motion






25. Is the inability to recognize faces






26. The physical intensity of light






27. Located by the cornea






28. We see objects because of the light they reflect






29. 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.






30. The optic nerve is made up of...






31. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina






32. Takes place when receptors for a particular sense detect a stimulus.






33. Is the tendency to complete incomplete figures






34. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle






35. Is the minimum amount of stimuli that can be detected 50% of the time






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






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






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






39. Refers to the entire span that can be perceived or detected by the eye at a given moment.






40. 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'






41. Curces are graphical representations of a subject'S sensitivity to a stimulus






42. Rods and cones on the retina that are responsible for sensory transduction.






43. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.

44. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






45. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation

46. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina






47. Is the tendency to see what is easiest or logical to see






48. Saying you detect a stimulus that is not there






49. Defined the Just Noticeable Difference






50. All the things a person sees trains them to perceive
