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






2. Has monocular and binocular cues






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






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






5. Failing to detect a present stimulus






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






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






8. 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






9. We see objects because of the light they reflect






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






11. 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






12. Asserts that perception and cognition are largely innate






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






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






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






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






17. Is the tendency to complete incomplete figures






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






19. Correctly sensing a stimulus






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






21. 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






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






23. 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.






24. 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






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






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






27. Is the inability to recognize faces






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

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






30. Why do cones see better than rods?






31. Saying you detect a stimulus that is not there






32. 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.






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






34. He tendency to group together items that are near each other






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






36. How we organize or experience sensations






37. 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.






38. 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.






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






40. Or overlap of objects shows which objects are closer






41. Famous for the theory of color blindness






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






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






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






45. Best at seeing fine details






46. Proposed the perceptual development and optic array






47. Defined the Just Noticeable Difference






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






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






50. 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
