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






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






3. Is the tendency to complete incomplete figures






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






5. Failing to detect a present stimulus






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






7. 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.






8. Asserts that perception and cognition are largely innate






9. Correctly sensing a stimulus






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






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






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






13. Has monocular and binocular cues






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






15. Along the visual pathway is the...






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






17. 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.






18. 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






19. 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






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






21. Found that infants prefer relatively complex and sensational displays






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






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






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






25. 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.






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






27. Or overlap of objects shows which objects are closer






28. Rods and cones on the retina that are responsible for sensory transduction.






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






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






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






32. 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.






33. humans best hear at






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






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






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






37. Comes from the complexity of the sound wave






38. All the things a person sees trains them to perceive






39. 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.






40. Saying you detect a stimulus that is not there






41. The feeling that results from physical stimulation






42. 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






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






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






45. 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






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






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






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






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






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