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.

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






2. humans best hear at






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






4. 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






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






6. 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.






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






8. Comes from the complexity of the sound wave






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






10. Asserts that perception and cognition are largely innate






11. Why do cones see better than rods?






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

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






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






15. The feeling that results from physical stimulation






16. Proposed the perceptual development and optic array






17. Is the inability to recognize faces






18. 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






19. Famous for the theory of color blindness






20. 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






21. 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.






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






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






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






25. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






26. Best at seeing fine details






27. Defined the Just Noticeable Difference






28. Has monocular and binocular cues






29. 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.






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






31. Rightly stating that no stimulus exists






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






33. 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






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






35. Saying you detect a stimulus that is not there






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






37. The physical intensity of light






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






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






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






41. How we organize or experience sensations






42. 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






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






44. Or overlap of objects shows which objects are closer






45. Is the tendency to complete incomplete figures






46. 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






47. 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.






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






49. He tendency to group together items that are near each other






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