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






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






3. Along the visual pathway is the...






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






5. The chemical that aids the receptor cells in transduction






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






7. 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.






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






9. Is the result of regeneration of retinal pigment






10. Why do cones see better than rods?






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






12. Found that infants prefer relatively complex and sensational displays






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






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






15. How we organize or experience sensations






16. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'






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






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






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






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






21. 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.






22. 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.






23. 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






24. 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






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






26. Proposed the perceptual development and optic array






27. The physical intensity of light






28. Famous for the theory of color blindness






29. Has monocular and binocular cues






30. 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

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






32. The feeling that results from physical stimulation






33. 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






34. 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






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






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






37. 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.






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






39. Proposed the opponent color/process theory






40. Located by the cornea






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






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