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






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






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






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

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






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






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






8. How we organize or experience sensations






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






10. 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






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






12. 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.






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






14. 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






15. 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






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






17. Saying you detect a stimulus that is not there






18. Proposed the perceptual development and optic array






19. Along the visual pathway is the...






20. 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






21. Or overlap of objects shows which objects are closer






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






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






24. Is the result of regeneration of retinal pigment






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






26. Is the inability to recognize faces






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






28. 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






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






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






32. Rightly stating that no stimulus exists






33. Has monocular and binocular cues






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






35. Curces are graphical representations of a subject'S sensitivity to a stimulus






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






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






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






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






40. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.






41. Is the tendency to complete incomplete figures






42. 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.






43. The chemical that aids the receptor cells in transduction






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






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






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






47. Defined the Just Noticeable Difference






48. 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






49. 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.






50. Famous for the theory of color blindness
