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. 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






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






3. 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

4. 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.






5. Has monocular and binocular cues






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






7. We see objects because of the light they reflect






8. Asserts that perception and cognition are largely innate






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






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






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






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






13. Is the tendency to complete incomplete figures






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






15. Defined the Just Noticeable Difference






16. Famous for the theory of color blindness






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






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






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






20. 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






21. 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.






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






23. The chemical that aids the receptor cells in transduction






24. 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.






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






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






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






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






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






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






31. Found that infants prefer relatively complex and sensational displays






32. How we organize or experience sensations






33. Is the inability to recognize faces






34. Knowing that an elephant is large no matter how it might appear






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






36. Can be perceived as two different things depending on how you look at them






37. Located by the cornea






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






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






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






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






42. Proposed the perceptual development and optic array






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






44. Failing to detect a present stimulus






45. 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






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. Comes from the complexity of the sound wave






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






49. Why do cones see better than rods?






50. Rightly stating that no stimulus exists
