GRE Psychology: Perception Sensation

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. 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






2. Is the tendency to complete incomplete figures






3. Or overlap of objects shows which objects are closer






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






5. 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'






6. Comes from the complexity of the sound wave






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






8. 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






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






10. 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






11. 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






12. Best at seeing fine details






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






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






15. Famous for the theory of color blindness






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






17. 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.






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. 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.






20. The chemical that aids the receptor cells in transduction






21. 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






22. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance






23. Asserts that perception and cognition are largely innate






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






25. Found that infants prefer relatively complex and sensational displays






26. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






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






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






29. 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.






30. 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






31. Why do cones see better than rods?






32. Has monocular and binocular cues






33. 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






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






35. Is the result of regeneration of retinal pigment






36. Along the visual pathway is the...






37. Is the inability to recognize faces






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






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






40. 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.






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






42. The feeling that results from physical stimulation






43. How we organize or experience sensations






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






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






46. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl






47. Proposed the perceptual development and optic array






48. 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


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






50. Rightly stating that no stimulus exists
