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






2. Failing to detect a present stimulus






3. 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






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






5. The physical intensity of light






6. Found that infants prefer relatively complex and sensational displays






7. The clear protective coating on the outside of the eye






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

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






10. Comes from the complexity of the sound wave






11. Or overlap of objects shows which objects are closer






12. 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.






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






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






15. 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.






16. 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






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






18. 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






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






20. 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






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

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






23. Located by the cornea






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






25. 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






26. 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






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






28. Is the result of regeneration of retinal pigment






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






30. The feeling that results from physical stimulation






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






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






33. We see objects because of the light they reflect






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






35. Defined the Just Noticeable Difference






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






37. 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






38. 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.






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






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






41. Is the tendency to complete incomplete figures






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






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






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






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






46. 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






47. Has monocular and binocular cues






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






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






50. Proposed the opponent color/process theory
