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






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






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






4. 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






5. 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.






6. Found that infants prefer relatively complex and sensational displays






7. How we organize or experience sensations






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






9. 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'






10. Famous for the theory of color blindness






11. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance






12. The chemical that aids the receptor cells in transduction






13. 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


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






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






16. 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






17. Located by the cornea






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






19. Best at seeing fine details






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


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






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






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






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






25. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision






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






27. 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






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






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






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






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






32. The physical intensity of light






33. 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.






34. Has monocular and binocular cues






35. 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.






36. 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






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






38. 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.






39. 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






40. Saying you detect a stimulus that is not there






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






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






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






44. The feeling that results from physical stimulation






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






46. 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.






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






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






49. 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






50. Failing to detect a present stimulus
