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. Saying you detect a stimulus that is not there






2. 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






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






4. 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.






5. 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






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






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






8. Has monocular and binocular cues






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






10. The physical intensity of light






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






12. 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'






13. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.






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






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






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

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






18. We see objects because of the light they reflect






19. 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






20. Located by the cornea






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






22. Failing to detect a present stimulus






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

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






25. 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






26. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear






27. Is the inability to recognize faces






28. Comes from the complexity of the sound wave






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






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






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






32. How we organize or experience sensations






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






34. Asserts that perception and cognition are largely innate






35. Found that infants prefer relatively complex and sensational displays






36. humans best hear at






37. 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.






38. 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.






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






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






41. Or overlap of objects shows which objects are closer






42. 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






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






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






45. The feeling that results from physical stimulation






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






47. Correctly sensing a stimulus






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






49. 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.






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