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 part of the world that triggers a particular neuron






2. 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






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






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






5. How we organize or experience sensations






6. Rightly stating that no stimulus exists






7. The physical intensity of light






8. Best at seeing fine details






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






10. 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.






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






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






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

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






15. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.






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






17. 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






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






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






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






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






22. 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






23. Failing to detect a present stimulus






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






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






26. Asserts that perception and cognition are largely innate






27. The chemical that aids the receptor cells in transduction






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






29. 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.






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






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






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






33. humans best hear at






34. Comes from the complexity of the sound wave






35. 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.






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






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

38. Found that infants prefer relatively complex and sensational displays






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






40. Proposed the opponent color/process theory






41. Correctly sensing a stimulus






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






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






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






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






47. 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






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






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






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