Chapter 5 The Perceiving Mind: Sensation and Perception

Question 1

Absolute Threshold

Answer 1

The smallest amount of stimulus that can be detected.

Question 2

Audition

Answer 2

The sense of hearing.

Question 3

Auditory Nerve

Answer 3

The nerve carrying sound information from the cochlea to the brain.

Question 4

Basilar Membrane

Answer 4

Membrane in the cochlea on which the organ of Corti is located.

Question 5

Binocular Cues

Answer 5

A depth cue that requires the use of both eyes

Question 6

Bottom-Up Processing

Answer 6

Perception based on building simple input into more complex perceptions

Question 7

Cochlea

Answer 7

The structure in the inner ear that contains auditory receptors.

Question 8

Cones

Answer 8

A photoreceptor in the retina that processes color and fine detail.

Question 9

Cornea

Answer 9

The clear surface at the front of the eye that begins the process of directing light to the retina.

Question 10

Depth Perception

Answer 10

The ability to use the two-dimensional image projected on the retina to perceive three dimensions

Question 11

Difference Threshold

Answer 11

The smallest detectable difference between two stimuli.

Question 12

Fovea

Answer 12

An area of the retina that is specialized for highly detailed vision.

Question 13

Gate Theory

Answer 13

The theory that suggests that input from touch fibers competes with input from pain receptors, possibly preventing pain messages from reaching the brain.

Question 14

Gustation

Answer 14

Question 15

Iris

Answer 15

The brightly colored circular muscle surrounding the pupil of the eye.

Question 16

Lens

Answer 16

The clear structure behind the pupil that bends light toward the retina.

Question 17

Monocular Cues

Answer 17

A depth cue that requires the use of only one eye

Question 18

Olfaction

Answer 18

Question 19

Olfactory Bulbs

Answer 19

One of two structures below the frontal lobes of the brain that receive input from the olfactory receptors in the nose.

Question 20

Olfactory Nerve

Answer 20

A nerve carrying olfactory information from the olfactory receptors to the olfactory bulbs.

Question 21

Opponent Process Theory

Answer 21

A theory of color vision that suggests we have a red-green color channel and a blue-yellow color channel in which activation of one color in each pair inhibits the other color

Question 22

Optic Nerve

Answer 22

The nerve exiting the retina of the eye.

Question 23

Optic Tracts

Answer 23

Nerve pathways traveling from the optic chiasm to the thalamus, hypothalamus, and midbrain.

Question 24

Organ of Corti

Answer 24

A structure located on the basilar membrane that contains auditory receptors.

Question 25

Papillae

Answer 25

Small bumps on the tongue that contain taste buds.

Question 26

Perception

Answer 26

The process of interpreting sensory information.
