Question 0

Stimulus has two dimensions

Answer 0

Qualitative and quantitative dimensions

Question 1

Sensory coding

Answer 1

Process by which the receptors convey such a range of information to the brain

Question 2

Qualitative dimension

Answer 2

Is coded and expressed by which neurons are firing

Question 3

Neurons firing in the occipital lobe

Answer 3

Indicates that the sensory information is light

Question 4

Neurons firing in the temporal lobe

Answer 4

Indicate that the sensory stimulus is sound

Question 5

Cornea

Answer 5

Protective layer on the outside of the eye

Question 6

Lens

Answer 6

Under the cornea

Curvature of the lens changes to accommodate for distance A.k.a. accommodations

Question 7

Retina

Answer 7

Back of the eye
Serves as the screen onto which the proximal stimulus is projected
Covered with receptors known as rods and cones

Question 8

Rods

Answer 8

Located on the periphery of the retina are sensitive in lowlight

Question 9

Foeva

Answer 9

Center of the retina

Question 10

Cones

Answer 10

Concentrated in the center of the retina are sensitive to bright light and color vision

Question 11

Hue

Answer 11

Wavelengths of light

Question 12

Pitch

Answer 12

Wavelengths of frequency of sound

Question 13

Physical characteristic of amplitude

Answer 13

Perceive as brightness for light and loudness for sound

Question 14

Physical trait of complexity

Answer 14

Known saturation when dealing with light and timbre when referring to sound

Question 15

Sensory neurons respond to differing environmental stimuli

Answer 15

By altering their firing rate and the regularity of their firing pattern

Question 16

Single cell recording

Answer 16

Technique by which the firing rate and pattern of a single preceptor so can be measured in response to varying sensory input

Question 17

Visual sensation

Answer 17

Occurs when the eye receives light input from the outside world

Question 18

Distal stimulus

Answer 18

The object as it exists in the environment is known as

Question 19

Proximal stimulus

Answer 19

The image of that object on the retina

Question 20

Bipolar and amacrine cells

Answer 20

After light stimulates the receptors, this information passes through these where some low-level information processing may occur

Question 21

Optic nerves

Answer 21

Stimulation travels to the ganglion cells of this after the bipolar and amacrine cells

Question 22

Optic chiasma

Answer 22

Where the optic nerves cross

Send half of the information from each visual field to the opposite side of the brain

Question 23

Serial processing

Answer 23

Occurs when the brain computes information step-by-step in a methodical and linear matter

Question 24

Parallel processing

Answer 24

Happens when the brain computes multiple pieces of information simultaneously

Question 25

Feature detector neurons

Answer 25

“See” different parts of the pattern, such as a line set at a specific angle to the background

Question 26

Convergence

Answer 26

Information becomes more complex as it travels through the sensory system

Question 27

Once lines and colors have been sensed, the information travels through two pathways

Answer 27

The dorsal stream and the ventral stream

Question 28

Ventral stream

Answer 28

The what pathway that connects to the prefrontal cortex, allowing a person to recognize an object

Question 29

Dorsal stream

Answer 29

The where pathway that integrates visual information with the other senses through a connection to the somatosensory cortex at the top of the brain

Question 30

Young-Helmholtz or trichromatic theory

Answer 30

The cones in the retina of the eyes are activated by light waves associated with blue, red, and green
See all colors by mixing these three

Question 31

Opponent process theory

Answer 31

Cells within the Salamis respond to a opponent pairs of receptor sets
Black/white
Red/green
Blue/yellow
If one color of the set is activated, the other is essentially turned off

Question 32

Color blindness

Answer 32

Responds to the opponent process theory

Most color blindness occurs in males, which provides strong evidence that this is a sex linked genetic condition

Question 33

Dichromats

Answer 33

People who cannot distinguish along the red/green or blue/yellow continuums

Question 34

Monochromats

Answer 34

See only and shades of black and white
