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






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






3. Rightly stating that no stimulus exists






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






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






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






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






8. 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.






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






10. 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.






11. 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






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






13. Found that infants prefer relatively complex and sensational displays






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






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






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






17. 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.






18. 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






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






20. We see objects because of the light they reflect






21. 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






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






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






24. The physical intensity of light






25. Located by the cornea






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






27. 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






28. Best at seeing fine details






29. Correctly sensing a stimulus






30. 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






31. 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






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

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






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






35. Defined the Just Noticeable Difference






36. 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






37. 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

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






39. Has monocular and binocular cues






40. Is the tendency to complete incomplete figures






41. humans best hear at






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






43. 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.






44. Proposed the perceptual development and optic array






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






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






47. The feeling that results from physical stimulation






48. Asserts that perception and cognition are largely innate






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






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