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. 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.






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






3. 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'






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






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






6. 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






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


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






9. 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






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






11. Found that infants prefer relatively complex and sensational displays






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


13. Defined the Just Noticeable Difference






14. 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.






15. The feeling that results from physical stimulation






16. 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.






17. Best at seeing fine details






18. Along the visual pathway is the...






19. Or overlap of objects shows which objects are closer






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






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






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






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






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






25. Famous for the theory of color blindness






26. Comes from the complexity of the sound wave






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






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






29. 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






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






31. Has monocular and binocular cues






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






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






34. Asserts that perception and cognition are largely innate






35. Is the minimum amount of stimuli that can be detected 50% of the time






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






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






38. 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.






39. 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.






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






41. 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.






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






43. How we organize or experience sensations






44. We see objects because of the light they reflect






45. Is the inability to recognize faces






46. The chemical that aids the receptor cells in transduction






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






48. 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






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






50. 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
