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. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






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






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






6. Has monocular and binocular cues






7. Failing to detect a present stimulus






8. 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.






9. Is knowing the color of an object even with tinted glasses on






10. 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






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






12. 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






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






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






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






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






17. Along the visual pathway is the...






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






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






20. 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.






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






22. 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






23. Why do cones see better than rods?






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






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






26. The chemical that aids the receptor cells in transduction






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






28. Proposed the perceptual development and optic array






29. Saying you detect a stimulus that is not there






30. Refers to the entire span that can be perceived or detected by the eye at a given moment.






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






32. Has been called the most important depth cue. Our eyes view objects from two slightly different angles - which allows us to create a 3-dimensional figure






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






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






35. 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.






36. 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.






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






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






39. Located by the cornea






40. 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.






41. 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.






42. Comes from the complexity of the sound wave






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






44. Asserts that perception and cognition are largely innate






45. 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






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






47. Is the tendency to complete incomplete figures






48. 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.






49. 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






50. 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.
