Q

The adjustable opening in the center of the eye through which light enters

A

Pupil

29
Q

A ring of muscle tissue that forms the colored portion of they eye around the pupil and controls the size of a pupil opening

A

Iris

30
Q

The transparent structure behind the pupil that changes shape to help focus images on the retina

A

Lens

31
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

32
Q

The process by which the eyes lens changes shape to focus near or far objects on the retina

A

Accommodation

33
Q

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

A

Rods

34
Q

Retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well-lit conditions. They detect fine detail and give rise to color sensation.

A

Cones

35
Q

The nerve that carries neural impulses form the eye to the brain

A

Optic nerve

36
Q

The point at which the optic nerve leaves the eye, creating a “blind” spot because no receptor cells are located there

A

Blind spot

37
Q

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

A

Fovea

38
Q

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

A

Feature detectors

39
Q

The processing of many aspects of a problem simultaneously; the brains natural 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

40
Q

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

A

Gestalt

41
Q

The organization of the visual field into objects (the figures) that stand out from their surroundings (the ground).

A

Figure-ground

42
Q

The perceptual tendency to organize stimuli into coherent groups

A

Grouping

43
Q

The ability to see objects in three dimensions although the images that strike the retina are two-dimensional; allows for us to judge distance

A

Depth perception

44
Q

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

A

Visual cliff

45
Q

Depth cues, such as retinal disparity, that depend on the use of two eyes

A

Binocular cues

46
Q

A binocular cue for perceiving depth; by comparing images from the retinas in the two eyes, the brain computes distance- the greater the disparity (difference) between the two images, the closer it is

A

Retinal disparity

47
Q

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

A

Monocular cues

48
Q

An illusion of movement created when two or more adjacent lights blink on and off in quick sessions

A

Phi phenomenon

49
Q

Perceiving objects as unchanging (having constant shapes, sizes, brightness, and color) even as illumination and retinal images change

A

Perceptual constancy

50
Q

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

A

Color constancy

51

Q

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

A

Place theory

62
Q

In hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of the tone, thus enabling us to sense its pitch

A

Frequency theory

63
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 op[ned 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
