- 35. the innermost part of the ear, containing the cochlea, semicircular canals and vestibular sacs
- 36. the dimension of color that is determined by the wavelength of light, what we know as the color names blue, green, and so forth
- 38. perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object
- 41. the amount of energy in a light wave or sound wave, which influences what we pervceive as brightness or loudness, intensity is determined by wave's aplitude (height)
- 42. the minimum difference between two stimuli required for detection 50 percent of the time
- 45. the ability to adjust to changed sensory input, including an artifically displaced or even inverted visual field
- 50. the principle that one sense may influence another, as when the smell of food influences it's taste
- 52. the eye's clear, protective outer layer, covering the iris and pupil
- 55. retinal receptors that are concentrated near the center of the retina and that function in daylight or in well lit conditions. cones detect fine detail and give rise to color sensations
- 57. a device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea
- 58. analysis that begins with the sensory receptors and works up to the brain's integration of sensory information
- 59. our movement sense
- 60. the study of paranormal phenomena, including ESP and psychokinesis
- 61. perception the ability to see objects in three dimensions althought the images that strike the retina are two dimensional, allows us to judge distance
- 62. information processing guided by higher level mental processes as when we construct perceptions drawing on our experiences and expectations
- 63. a depth cue, such as retinal disparity, that depends on the use of two eyes
- 64. process by which our sensory receptors and nervous system receive and represent stimulus energies from our enviroment
- 65. the perceptual tendencry to organize stimuli into coherent groups
Down
- 1. the principle that to be perceived as different, two stimuli must differ by a constant minimum percentage
- 2. the theory that opposing retinal process (red/green,blue/yellow,white/black0 enable color vision.
- 6. conversion of one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells, into neural impusles our brain can interpret
- 7. a coiled, bony fluid filled tube in the inner ear, sound waves traveling through the cochlear fluid trigger nerve impulses
- 9. the adjustable opening in the centrer of the eye through which light enters
- 10. the nerve that carries neural impules from the eye to the brain
- 11. a ring of muscle tissure that forms the colored portion of the eye around the pupil and controls the size of the pupil opening
- 14. hearing loss caused by damage to the cochlea's receptor cells or the auditory nerves; the most common form of hearing loss
- 15. the sense of smell
- 17. in hearing the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense it's pitch
- 18. theory that the retina contains three different types of color receptors-one most sensitive to red, one to green, one to blue, which when stimulated in combination can produce the perception of any color
- 21. perceiving objects as unchanging even as illumination and retinal images change
- 22. the organization of the visual field into objects that stand out from their surroundings
- 24. processing many aspects of a problem simultaneousley
- 25. the number of complete wavelengths that pass a point in a given time
- 27. a labratory device for testing depth perception in infants and young animals
- 28. the study of relationships between the physical charcteristics of stimuli, such as their intensity, and our psychological experience of them
- 29. the activation, often unconciously, of certain associations, thus predisposing one's perception, memory, or response
- 30. a binocular cue for perceiving depth. By comparing retinal images from the two eyes, the brain computes distance-the greater the disparity between the two images the closer the object
- 32. the transparent structure behind the pupil that changes shape to help focus images on the retina
- 33. the focusing of concious awareness on a particular stimulus
- 37. failing to notice changes in the enviroment a form of inattentional blindness
- 39. a mental predispostition to perceive on thing and not another
- 40. a theory predicting how and when we detect the presence of a faint amid background stimultation. assumes there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and alertness
- 43. controversial claim that perception can occur appart from sensory input, includes telapathy, calirvoyance, and precognition
- 44. the light sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information
- 46. a tone's expercinced highness or lowness, depends on frequency
- 47. the point at which the optic nerve leaves the eye creating a "blind" spot ecause no receptor cells are located there
- 48. the process of organizing and interpreting sensory information, enaling us tot recognize meaniful objects and events
- 49. retinal receptors that detect black, white, and gray, and are sensitive to movement, necessary for peripheral and twilight vision when cones don't respond
- 51. the process by which the eye's lens changes shape to focus near or far objects on the retina
- 53. an organized whole. Gestalt psychologists emphasized our tendencry to integrate pieces of information into meaningful wholes
- 54. the distance from the peak of one light or sound wave to the peak of the next
- 56. in hearing the theory that links the ptich we hear with the place where the cochlea's membrane is stimulated
