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






2. 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.






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






4. Correctly sensing a stimulus






5. 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






6. We see objects because of the light they reflect






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






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






9. 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






10. 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






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






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






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






14. Failing to detect a present stimulus






15. 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.






16. Is the inability to recognize faces






17. 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






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






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






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






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






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






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






24. Famous for the theory of color blindness






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






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

27. Factors into why we see what we expect to see






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






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






30. Is the result of regeneration of retinal pigment






31. The feeling that results from physical stimulation






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






33. Defined the Just Noticeable Difference






34. Has monocular and binocular cues






35. The chemical that aids the receptor cells in transduction






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






37. 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






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






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






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






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






42. 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






43. 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






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






45. Comes from the complexity of the sound wave






46. How we organize or experience sensations






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






48. 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






49. Along the visual pathway is the...






50. Or overlap of objects shows which objects are closer
