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






2. Correctly sensing a stimulus






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






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






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






7. Along the visual pathway is the...






8. Defined the Just Noticeable Difference






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






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






11. Proposed the opponent color/process theory






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






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






14. humans best hear at






15. 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

16. Located by the cornea






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






18. Why do cones see better than rods?






19. 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






20. 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.






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






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






23. 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.






24. 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






25. Saying you detect a stimulus that is not there






26. The feeling that results from physical stimulation






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






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






29. 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






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






31. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear






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






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






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






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






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






37. Is the tendency to complete incomplete figures






38. 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.






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






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






41. Famous for the theory of color blindness






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






43. Or overlap of objects shows which objects are closer






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






46. 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






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






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






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. 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'
