25
Q

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.

A

Retina

26
Q

The process by which the eye’s lens changes shape to focus near or far objects on the retina.

A

Accomodation

27
Q

Retinal receptors that detect black, white and gray; necessary for peripheral and twilight vision, when cones don’t respond.

A

Rods

28
Q

The retinal receptor cells that are concentrated in the center of the retina and function in daylight or well-lit conditions. Detect fine detail and give rise to color sensations.

A

Cones

29
Q

The nerve that carries neural impulses from the eye to the brain.

A

Optic Nerve

30
Q

The point at which the optic nerve leaves the eye, creating a _______ because no receptor cells are located there.

A

Blind Spot

31
Q

The central focal point in the retina, around which the eye’s cones cluster.

A

Fovea

32
Q

Nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement.

A

Feature detectors

33
Q

The processing of many aspects of a problem simultaneously; the brain’s neural mode of information processing for many functions, including vision. Contrasts with the step-by-step (serial) processing of most computers and of conscious problem solving.

A

Parallel Processing

34
Q

The theory that the retina contains 3 different color receptors–one sensitive to red, one to green, and one to blue–which, when stimulated in combination, can produce the perception of other colors.

A

Young- Helmholtz Trichromatic Theory

35
Q

The theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision.

A

Opponent- Processing Theory

36
Q

An organized whole. ______ psychologists emphasized our tendency to integrate pieces of information into meaningful wholes.

A

Gestalt

37
Q

The organization of the visual field into objects that stand out from there surroundings.

A

Figure- Ground

38
Q

The perceptual tendency to organize stimuli into coherent groups.

A

Grouping

39
Q

The ability to see objects in 3-D even though the images that strike the retina are 2 dimensional. Allows us to judge distance.

A

Depth Perception

40
Q

A laboratory device used for testing depth perception in infants and young animals.

A

Visual Cliff

41
Q

Depth clues, like retinal disparity, that depend on the use of two eyes.

A

Binocular clues

42
Q

A binocular clue for perceiving depth: by comparing images from the retinas in two eyes, the brain computes distance; the greater the disparity (difference) between the two images, the closer the objects.

A

Retinal Disparity

43
Q

Depth cues, such as interposition and linear perspective, available to either eye alone.

A

Monocular Cues

44
Q

An illusion of movement created when two or more adjacent lines blink on and off in quick succession.

A

Phi Phenomenon

45
Q

Perceiving objects as unchanging (having consistent shapes, size, brightness, and color) even as illumination and retinal images change.

A

Perceptual Constancy

46
Q

Perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object.

A

Color Constancy

47
Q

In vision, the ability to adjust to an artificially displaced or even inverted visual field.

A

Perceptual Adaptation

48
Q

The sense or act of hearing.

A

Audition

49
Q

The number of complete wavelengths that pass a point in a given time (for example, per second).

A

Frequency

50
Q

A tone’s experienced highness or lowness; depends on frequency

A

Pitch

51
Q

The chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochlea’s oval window.

A

Middle Ear

52
Q

a coiled, bony, fluid-filled tube in the inner ear; sound waves traveling through the cochlear fluid trigger nerve impulses.

A

Cochlea

53
Q

The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs.

A

Inner Ear

54
Q

Hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerves.

A

Sensorineural Hearing Loss

55
Q

Hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea.

A

Conduction Hearing Loss

56
Q

A device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea.

A

Cochlear Implant

57
Q

In hearing, the theory that links the pitch we hear with the place where the cochlea’s membrane is stimulated.

A

Place Theory

58
Q

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 its pitch.

A

Frequency Theory

59
Q

The theory that the spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain. The “gate” is opened by the activity of pain signals traveling up small nerve fibers and is closed by activity in larger fibers or by information coming from the brain.

A

Gate-Control Theory

60
Q

A system for sensing the position and movement of individual body parts.

A

Kinesthesia

61
Q

The sense of body movement and position, including the sense of balance.

A

Vestibular Sense

62
Q

The principle that one sense may influence another, as when the smell of food influences its taste.

A

Sensory Interaction

63
Q

In psychological science, the influence of bodily sensations, gestures, and other states on cognitive preferences and judgements.
