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. Along the visual pathway is the...






2. 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.






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






4. 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






5. Why do cones see better than rods?






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






7. 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.






8. Failing to detect a present stimulus






9. Found that infants prefer relatively complex and sensational displays






10. Saying you detect a stimulus that is not there






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






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






13. Proposed the opponent color/process theory






14. The physical intensity of light






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






16. 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






17. The optic nerve is made up of...






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






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






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






21. Has monocular and binocular cues






22. Best at seeing fine details






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






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






25. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.






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






27. Defined the Just Noticeable Difference






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






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






30. We see objects because of the light they reflect






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






32. The chemical that aids the receptor cells in transduction






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






34. 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

35. 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






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






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






38. Located by the cornea






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






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






41. 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






42. How we organize or experience sensations






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






44. Rightly stating that no stimulus exists






45. 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






46. 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






47. humans best hear at






48. Is the inability to recognize faces






49. Asserts that perception and cognition are largely innate






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