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






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






3. 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






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






5. The chemical that aids the receptor cells in transduction






6. Famous for the theory of color blindness






7. Rightly stating that no stimulus exists






8. Has monocular and binocular cues






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






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






11. Is the tendency to complete incomplete figures






12. 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

13. Along the visual pathway is the...






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






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






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






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






18. Proposed the perceptual development and optic array






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






20. 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






21. Is the result of regeneration of retinal pigment






22. Or overlap of objects shows which objects are closer






23. 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






24. Comes from the complexity of the sound wave






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






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






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






28. Is the inability to recognize faces






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






30. 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.






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






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






33. 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






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






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






36. 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.






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






38. 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






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






40. 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'






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






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






43. The physical intensity of light






44. 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.






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






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






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

48. Failing to detect a present stimulus






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