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. 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






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






3. 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


4. Saying you detect a stimulus that is not there






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






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






8. The optic nerve is made up of...






9. Knowing that an elephant is large no matter how it might appear






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






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






12. 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.






13. 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






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






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






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






18. Comes from the complexity of the sound wave






19. Can be perceived as two different things depending on how you look at them






20. 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






21. 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






22. The feeling that results from physical stimulation






23. Proposed the opponent color/process theory






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






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






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






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






28. Failing to detect a present stimulus






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






30. 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.






31. 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.






32. 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.






33. 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.






34. Is the tendency to complete incomplete figures






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






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






37. Is the inability to recognize faces






38. Best at seeing fine details






39. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






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


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






42. We see objects because of the light they reflect






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






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






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






46. 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






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






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






49. 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






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