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 knowing the color of an object even with tinted glasses on






2. Is the result of regeneration of retinal pigment






3. Along the visual pathway is the...






4. The physical intensity of light






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

6. Why do cones see better than rods?






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






8. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






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






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

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






12. Located by the cornea






13. Proposed the perceptual development and optic array






14. The chemical that aids the receptor cells in transduction






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






16. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou






17. 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'






18. 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.






19. Found that infants prefer relatively complex and sensational displays






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






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






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






23. 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






24. Best at seeing fine details






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






26. 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






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






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






29. We see objects because of the light they reflect






30. 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






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






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






33. 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.






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






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






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






37. Comes from the complexity of the sound wave






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






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






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






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






42. Defined the Just Noticeable Difference






43. 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






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






45. 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.






46. 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.






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






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






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






50. humans best hear at
