- 21. constructs perceptions from this sensory input by drawing on your experience and expectations
- 27. the innermost part of the ear containing the cochlea, semicircular canals, and vestibular sacs
- 29. the activation of certain associations thus predisposing one's perception of memory or response
- 32. retinal receptors that detect black and white, and are sensitive to movement, found in retina's outer regions
- 33. the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch
- 34. a coiled, bony, fluid-filled tube in the inner ear that travels sound waves through its fluid to trigger nerve impulses
- 35. to separate faces from their backgrounds; perceiving any object as distinct from its surroundings
- 37. the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated
- 39. an organized whole. our tendency to integrate pieces of information into meaningful wholes
- 41. the eye's clear protective outer layer, where light enters and then bends to provide focus
- 43. the ability to adjust to changed sensory input
- 45. The process when our sensory receptors and nervous system receive and represent stimulus from our environment
- 47. the sense or act of hearing
- 48. the amount of energy in a light/sound wave; Intensity is determined by the wave's amplitude
- 50. the influence of bodily sensations, gestures, and other states on cognitive preferences and judgments
- 51. the minimum stimulus energy needed to detect a particular stimulus 50% of the time
- 52. a tone's experienced highness or lowness; depends on the frequency
- 54. our system for sensing the position and movement of individual body parts
- 56. the point when the optic nerve leaves the eye because no receptor cells are located in that spot
- 58. a test of depth perception in infants and young animals
- 59. an illusion of movement created when two or more adjacent lights blink on and off in quick succession
- 60. the study of relationships between the physical characteristics of stimuli and our psychological experience of them
- 61. perceiving objects as unchanging even as retinal images change; such as consistent color, brightness, shape, and size
- 62. our sense of body movement and position that enables our sense of balance
- 63. a less common hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea
- 66. a theory predicting how and when we will detect faint stimulus amid background stimulus
Down
- 1. the sense of smell
- 2. the study of paranormal phenomena (including ESP and psychokinesis)
- 4. the perceptual tendency to organize stimuli into coherent groups
- 5. the process when the eyes lens changes shape to focus near or far objects on the retina
- 7. conversion of one form of energy to another; converting stimulus energies into neural impulses our brain can interpret
- 8. retinal receptor cells that function in daylight or in well-lit conditions. The cones detect fine detail and give rise to color sensations.
- 10. a device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea
- 11. transparent structure behind the pupil that changes shape to focus images on the retina
- 12. processing many aspects of a problem simultaneously
- 16. claim that perception can occur apart from sensory input (includes telepathy, clairvoyance, and precognition)
- 20. nerve cells in the brain's visual cortex that respond to specific features of the stimulus such as shape, angle, or movement
- 22. the ability to see objects in three dimensions although the images strike the retina as two dimensional
- 23. failing to see visible objects when our attention is directed elsewhere
- 24. the principle that two different stimuli must differ by a constant minimum percentage
- 25. a depth cue -such as retinal disparity- that depends on the use of two eyes
- 26. perceiving familiar objects as having consistent color, even if changing illumination alters wavelengths reflected by the object
- 28. the process of organizing and interpreting sensory information, enabling us to recognize objects and events
- 30. diminished sensitivity as a consequence of constant stimulation
- 31. a small adjustable opening in the center of the eye where light enters
- 36. multilayer tissue on the eye's inner surface, contains rods and cones and layers of neurons that process visual info
- 38. the focusing of conscious awareness of a particular stimulus
- 40. hearing loss caused by damage to the cochleas receptor cells or auditory nerves
- 42. the theory that the retina contains three different types of color receptors; red, green, and blue; which when combined can produce the perception of any color
- 44. a binocular for perceiving depth; our two eyes show the same image from different angles, and the brain computes the distance between them
- 46. the chamber between the eardrum and cochlea containing three tiny bones that concentrate the vibrations of the eardrum on the cochleas oval window
- 49. processing that starts at your sensory receptors and works up to higher levels of processing
- 53. the nerve that carries neural impulses from the eye to the brain

- 57. the number of complete wavelengths that pass a point in a given time
- 64. A colored muscle that dilates or constricts in response to light intensity
- 65. the dimension of color determined by the wavelength of light
