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. Refers to the entire span that can be perceived or detected by the eye at a given moment.






2. Failing to detect a present stimulus






3. 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.






4. 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






5. 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






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






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






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






9. Found that infants prefer relatively complex and sensational displays






10. 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.






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






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






13. Proposed the opponent color/process theory






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






15. Comes from the complexity of the sound wave






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






17. The physical intensity of light






18. The feeling that results from physical stimulation






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






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






21. The chemical that aids the receptor cells in transduction






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






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






24. 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






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






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






27. 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






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






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






30. 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.






31. 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






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






33. Rightly stating that no stimulus exists






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






35. 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






36. Defined the Just Noticeable Difference






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






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






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






40. 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

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

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. 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






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






45. 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.






46. 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'






47. 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.






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






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






50. Or overlap of objects shows which objects are closer
