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. The clear protective coating on the outside of the eye






2. Proposed the opponent color/process theory






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






5. Failing to detect a present stimulus






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






7. How we organize or experience sensations






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






9. Or overlap of objects shows which objects are closer






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






11. 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.






12. Correctly sensing a stimulus






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






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






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






16. 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






17. Defined the Just Noticeable Difference






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






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






20. Is the tendency to complete incomplete figures






21. 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






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






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






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






25. 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






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






27. The physical intensity of light






28. Asserts that perception and cognition are largely innate






29. Located by the cornea






30. We see objects because of the light they reflect






31. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.






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






33. 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






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






35. Is the result of regeneration of retinal pigment






36. 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.






37. Comes from the complexity of the sound wave






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






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






40. 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.






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






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






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






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






45. Best at seeing fine details






46. Proposed the perceptual development and optic array






47. 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.






48. The feeling that results from physical stimulation






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

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