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






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






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

4. 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.






5. Failing to detect a present stimulus






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






7. 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.






8. 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.






9. Along the visual pathway is the...






10. 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






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






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






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






14. 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






15. Found that infants prefer relatively complex and sensational displays






16. Is the inability to recognize faces






17. 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.






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






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






20. Is the minimum amount of stimuli that can be detected 50% of the time






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

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






23. Knowing that an elephant is large no matter how it might appear






24. 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.






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






26. 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.






27. Has monocular and binocular cues






28. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina






29. Is the result of regeneration of retinal pigment






30. Asserts that perception and cognition are largely innate






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






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






33. Comes from the complexity of the sound wave






34. 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'






35. Saying you detect a stimulus that is not there






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






37. We see objects because of the light they reflect






38. 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






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






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






41. 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.






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






43. The chemical that aids the receptor cells in transduction






44. 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






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






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






47. Famous for the theory of color blindness






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






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






50. 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
