GRE Psychology: Perception Sensation

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. Rightly stating that no stimulus exists






2. Or overlap of objects shows which objects are closer






3. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.






4. Factors into why we see what we expect to see






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






6. Located by the cornea






7. Has monocular and binocular cues






8. Saying you detect a stimulus that is not there






9. Along the visual pathway is the...






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






11. Famous for the theory of color blindness






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






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






14. 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.






15. Defined the Just Noticeable Difference






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






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






18. Is the inability to recognize faces






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






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






21. Why do cones see better than rods?






22. Comes from the complexity of the sound wave






23. The part of the world that triggers a particular neuron






24. Failing to detect a present stimulus






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






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






27. The physical intensity of light






28. 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'






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






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






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






32. The feeling that results from physical stimulation






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






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






35. Is the result of regeneration of retinal pigment






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






37. 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






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

39. 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






40. We see objects because of the light they reflect






41. 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.






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






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






44. 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.






45. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






46. Best at seeing fine details






47. 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.






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






49. Is the tendency to complete incomplete figures






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