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 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






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






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






4. 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.






5. Best at seeing fine details






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






7. Electrical impulses travel down these to the brain - where the information is understood






8. humans best hear at






9. 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






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






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






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






13. Is the result of regeneration of retinal pigment






14. 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.






15. 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






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






17. 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






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

19. 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






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






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






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






23. Failing to detect a present stimulus






24. Correctly sensing a stimulus






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






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






27. Proposed the perceptual development and optic array






28. Located by the cornea






29. 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






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






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






32. Defined the Just Noticeable Difference






33. Rightly stating that no stimulus exists






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






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






36. The feeling that results from physical stimulation






37. Is the tendency to complete incomplete figures






38. How we organize or experience sensations






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






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






41. 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






42. 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.






43. 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






44. Along the visual pathway is the...






45. The chemical that aids the receptor cells in transduction






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

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






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






49. Developed the visual cliff to study whether depth perception was innate






50. 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
