- 45. purity of wavelength
- 47. colored part of the eye, muscle that contracts the pupil
- 48. a perceptual cue in which we group together things that are near one another
- 49. beneath cornea, clear tissue, bends light rays so the retina can focus
- 51. Gradient the closer something is, the more detail one can perceive
- 52. receptor cells, detect color, located in the center of the retina
- 53. sense sense of equilibrium; located in inner ear; deals with motion sickness
- 55. Ground Perception minds have tendencies to organize pictures as separate enitities from the background
- 56. Analysis A step-by-step approach, break down objects by parts and match with templates in the brain to figure them out
- 57. clear, outer covering, protects the interior
- 58. Membrane Piece of skin streched over the entrance of the ear; vibrates to sound; separates the middle from the outer ear, eardrum
- 63. Processing sensory information is sent to the brain via sensory neurons to analyze
- 64. Binocular cues,retina bulges when things get closer
- 67. tiny hairs that receive odor molecules; act as receptors in nose and as filters
- 68. nerve endings sense light pressure
- 70. spectrum wavelengths of light which can be seen by the human eye
- 71. theory/trichromatic theory malfunction of cones which causes colorblindness
- 72. light Comes directly from the source, it has not been broken down into frequencies
- 73. skin sensation warmth, coldness, pain, pressure
- 74. snail shaped part of the ear filled with fluid and small hairs that vibrate to incoming sound
Down
- 1. olfaction; receptors located in mucous membrane
- 2. Constancy perception of the shape of object remains constant despite changes in the visual field
- 3. contains receptor cells, image forms here and attaches to the optic nerve
- 6. Frequency or rate of sound waves
- 8. spot area in each eye where you cannot see because this is where the optic nerve connects to the retina
- 9. Matching Theory look at the whole and match with template in the brain to figure it out
- 12. Processing templates in the brain give meaning to what one is seeing, then the information is sent
- 14. white part of the eye, provides protection and structure
- 18. perception controversial idea that messages below absolute threshold can influence behavior
- 19. detection theory no abolute threshold because thresholds change with a variety of factors like fatigue, attention, etc
- 20. A measure of how loud a sound is
- 23. sense joints, ligaments, muscles; allows bodies to move in space
- 24. colorblindness Difficulty seeing shades of red and green
- 29. deafness deafness due to damage to the bones of the middle ear ; is correctable
- 30. Vision eyes combine to create one visual image
- 32. colorblindness Complete color blindness
- 33. change in curvature of lens to focus eye sight
- 34. nerve smells transfer to this then sent to temporal lobe
- 35. Feature Detector theory Theory that says you need to practice seeing things during a critical period of development (before 2 years of age)
- 36. chasm junction where the two optic nerves cross
- 37. Perspective The farther away something is, the more blurry it looks. The closer it is, the clearer it looks
- 38. Knowing what is close to you and what is farther away based on one object blocking the other
- 39. acuity how accurate is perception
- 40. corpuscle detect deep pressure
- 43. consciously focusing on a limited stimuli
- 44. Membrane part of the cochlea which connects to the auditory nerves and takes information to the temporal lobe

- 50. a perceptual cue in which we group like things together
- 54. Noticeable Difference amount it took for one to notice a change
- 59. deafness not treatable; damage to auditory nerve system; problems with high pitch
