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






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






3. 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'






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






5. Why do cones see better than rods?






6. Has monocular and binocular cues






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






8. Proposed the opponent color/process theory






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






10. We see objects because of the light they reflect






11. Is the tendency to complete incomplete figures






12. 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






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






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






15. Best at seeing fine details






16. Comes from the complexity of the sound wave






17. 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






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






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






20. Along the visual pathway is the...






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






22. The physical intensity of light






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

24. 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






25. Is the tendency to create a whole or detailed figure based on our expectations rather than what is seen






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






27. Found that infants prefer relatively complex and sensational displays






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






29. Saying you detect a stimulus that is not there






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






31. He tendency to group together items that are near each other






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






33. 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.






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






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






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






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






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






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






40. humans best hear at






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






42. Applies to all senses but only to a limited range of intensities. The law states that a stimulus needs to be increased by a constant fraction of its original value in order to be noticeably different

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






44. 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.






45. 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.






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






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






48. 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






49. Is the result of regeneration of retinal pigment






50. Famous for the theory of color blindness
