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. Why do cones see better than rods?






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






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






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






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






6. Rightly stating that no stimulus exists






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






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






9. 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.






10. humans best hear at






11. Or overlap of objects shows which objects are closer






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






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






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






15. The physical intensity of light






16. 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.






17. Proposed the opponent color/process theory






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






19. 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.






20. Is the tendency to complete incomplete figures






21. 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.






22. 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






23. 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






24. Found that infants prefer relatively complex and sensational displays






25. Is the tendency to make figures out of symmetrical images






26. The chemical that aids the receptor cells in transduction






27. 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






28. Best at seeing fine details






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






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






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






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






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






34. 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






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






36. Failing to detect a present stimulus






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






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

39. Refers to the relationship between the meaningful part of a picture and the background






40. Comes from the complexity of the sound wave






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






42. 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






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






44. Along the visual pathway is the...






45. 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






46. 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






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






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






49. Saying you detect a stimulus that is not there






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