GRE Psychology: Perception Sensation

Subjects : gre, psychology
  • 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. Comes from the complexity of the sound wave

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

3. Involves both innate/sensory and is partially learned/conceptual

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

5. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.

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

7. 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.

8. How we organize or experience sensations

9. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.

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

11. Refers to how we see texture or fine detail differently from different distances

12. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information

13. Has monocular and binocular cues

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

15. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance

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

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

18. Rightly stating that no stimulus exists

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

20. After the optic chasm - information travels to the...

21. 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'

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

23. Objects that have been drawn and can be perceived but are geometrically impossible

24. 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.

25. Best at seeing fine details

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

27. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.

28. The feeling that results from physical stimulation

29. Or overlap of objects shows which objects are closer

30. Consists of one optic nerve connection each eye to the brain.

31. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl

32. Asserts that perception and cognition are largely innate

33. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz

34. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.

35. 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

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

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

38. 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

39. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward

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

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

42. Is the tendency to complete incomplete figures

43. The physical intensity of a sound wave largely determines loudness

44. humans best hear at

45. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear

46. Along the visual pathway is the...

47. Defined the Just Noticeable Difference

48. Gives us clues about how far away an object is if we know about how big the object should be

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

50. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou
