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. 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.






2. Is the inability to recognize faces






3. 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.






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






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






6. 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.






7. 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






8. Correctly sensing a stimulus






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






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






11. Saying you detect a stimulus that is not there






12. Proposed the perceptual development and optic array






13. 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






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. The feeling that results from physical stimulation






16. 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.






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






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






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






20. Failing to detect a present stimulus






21. 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






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






23. The chemical that aids the receptor cells in transduction






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






25. We see objects because of the light they reflect






26. 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'






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






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






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






30. Asserts that perception and cognition are largely innate






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






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






33. Best at seeing fine details






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






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






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






37. Or overlap of objects shows which objects are closer






38. Defined the Just Noticeable Difference






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






40. Found that infants prefer relatively complex and sensational displays






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






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






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






44. 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.






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






46. 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.






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






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

49. 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






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