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. Has monocular and binocular cues






2. 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






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






4. 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

5. 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.






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






7. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle






8. How we organize or experience sensations






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






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






11. Is the inability to recognize faces






12. Correctly sensing a stimulus






13. Asserts that perception and cognition are largely innate






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






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






16. 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






17. 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'






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






19. 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






20. Famous for the theory of color blindness






21. 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






22. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision






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






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






25. Saying you detect a stimulus that is not there






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






27. humans best hear at






28. 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






29. 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






30. Along the visual pathway is the...






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






32. 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.






33. Comes from the complexity of the sound wave






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

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






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






38. Is the tendency to complete incomplete figures






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

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






49. 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






50. 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.
