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. 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






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






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






4. The physical intensity of light






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






6. 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.






7. We see objects because of the light they reflect






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






9. Along the visual pathway is the...






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






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






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






13. Saying you detect a stimulus that is not there






14. 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






15. Famous for the theory of color blindness






16. Proposed the perceptual development and optic array






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






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






19. humans best hear at






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






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






22. The feeling that results from physical stimulation






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






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

25. Located by the cornea






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






27. Is the inability to recognize faces






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

29. Best at seeing fine details






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






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






32. Gives us clues about how far away an object is if we know about how big the object should be






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






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






35. 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.






36. 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






37. Failing to detect a present stimulus






38. 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

39. Or overlap of objects shows which objects are closer






40. 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






41. Found that infants prefer relatively complex and sensational displays






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






43. The chemical that aids the receptor cells in transduction






44. Asserts that perception and cognition are largely innate






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






46. Proposed the opponent color/process theory






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 make figures out of symmetrical images






49. Why do cones see better than rods?






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