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. The part of the world that triggers a particular neuron

2. Proposed the perceptual development and optic array

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

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

5. Asserts that perception and cognition are largely innate

6. Also known as color - is the dominant wavelength of light

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

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

9. 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.

10. 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

11. Has monocular and binocular cues

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

13. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc

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

15. Why do cones see better than rods?

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

17. Comes from the complexity of the sound wave

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

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

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

21. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright

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

23. Saying you detect a stimulus that is not there

24. Is the result of regeneration of retinal pigment

25. How we organize or experience sensations

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

27. Is the tendency to complete incomplete figures

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

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

30. 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

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

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

33. Failing to detect a present stimulus

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

35. 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.

36. The feeling that results from physical stimulation

37. 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'

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

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

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

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

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

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

44. Proposed the opponent color/process theory

45. Or overlap of objects shows which objects are closer

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

47. 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.

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

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

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