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






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






3. 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.






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






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






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






7. The chemical that aids the receptor cells in transduction






8. Consists of one optic nerve connection each eye to the brain.






9. Defined the Just Noticeable Difference






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






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






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






13. Or overlap of objects shows which objects are closer






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






15. 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.






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. Is the result of regeneration of retinal pigment






18. 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.






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

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






21. Is the tendency to complete incomplete figures






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






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






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






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






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






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






28. How we organize or experience sensations






29. 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






30. We see objects because of the light they reflect






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






32. 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.






33. Asserts that perception and cognition are largely innate






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






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






36. 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

37. Failing to detect a present stimulus






38. Correctly sensing a stimulus






39. 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.






40. Is the inability to recognize faces






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






42. 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.






43. 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






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






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






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






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






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






49. humans best hear at






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