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.

1. 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.






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






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






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






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






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






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






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






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






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






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






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






13. 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

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






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






16. 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






17. Best at seeing fine details






18. Located by the cornea






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






20. 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






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

22. 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






23. Proposed the opponent color/process theory






24. 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






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






26. Saying you detect a stimulus that is not there






27. 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.






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






29. 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






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






31. We see objects because of the light they reflect






32. 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.






33. Defined the Just Noticeable Difference






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






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






36. Asserts that perception and cognition are largely innate






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






38. 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






39. Has monocular and binocular cues






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






41. Famous for the theory of color blindness






42. The feeling that results from physical stimulation






43. Along the visual pathway is the...






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






45. Found that infants prefer relatively complex and sensational displays






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






47. Is the result of regeneration of retinal pigment






48. 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.






49. Comes from the complexity of the sound wave






50. Why do cones see better than rods?
