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






2. 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'






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


4. Is the tendency to complete incomplete figures






5. Famous for the theory of color blindness






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






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






8. Defined the Just Noticeable Difference






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






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






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






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






13. humans best hear at






14. 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.






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






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


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






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






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






20. 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.






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






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






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






24. 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






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






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






27. 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.






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






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






30. Proposed the opponent color/process theory






31. The chemical that aids the receptor cells in transduction






32. 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.






33. 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.






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






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






36. 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






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






38. Is the result of regeneration of retinal pigment






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






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






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






42. Correctly sensing a stimulus






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






44. 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






45. 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






46. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.






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






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. Along the visual pathway is the...






50. 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.
