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

2. Is the tendency to complete incomplete figures






3. Best at seeing fine details






4. Asserts that perception and cognition are largely innate






5. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.






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






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






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






9. 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.






10. 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






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






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






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






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






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






16. 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.






17. Has monocular and binocular cues






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






19. Failing to detect a present stimulus






20. 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'






21. Located by the cornea






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

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






24. The feeling that results from physical stimulation






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






26. humans best hear at






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






28. 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.






29. 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.






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






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






32. 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






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






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






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






36. How we organize or experience sensations






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






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






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






40. 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

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






42. Comes from the complexity of the sound wave






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






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






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






46. Proposed the perceptual development and optic array






47. Is the result of regeneration of retinal pigment






48. The physical intensity of light






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






50. Is the inability to recognize faces
