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. 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

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






3. The chemical that aids the receptor cells in transduction






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






5. Is the result of regeneration of retinal pigment






6. Asserts that perception and cognition are largely innate






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






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






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






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






11. Famous for the theory of color blindness






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






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






14. 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






15. How we organize or experience sensations






16. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright






17. 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






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






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






20. 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






21. Comes from the complexity of the sound wave






22. Or overlap of objects shows which objects are closer






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






24. 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






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






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






27. Is the inability to recognize faces






28. Has monocular and binocular cues






29. Proposed the opponent color/process theory






30. Defined the Just Noticeable Difference






31. 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.






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






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

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






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






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






37. The physical intensity of light






38. 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






39. Located by the cornea






40. We see objects because of the light they reflect






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






42. Why do cones see better than rods?






43. 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.






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






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






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






47. Best at seeing fine details






48. Saying you detect a stimulus that is not there






49. After the optic chasm - information travels to 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.
