Sensation & Perception Part 3

Question 1

Located in the visual cortex of the brain

Answer 1

Feature Detectors

Question 2

Nerve cells that selectively response to specific visual features, like movement, shape, or angle

Answer 2

Feature Detectors

Question 3

The basis for visual information processing

Answer 3

Feature Detectors

Question 4

Information processing in which several aspects of a stimulus, like light or sound are processed at the same time

Answer 4

Parallel Processing

Question 5

Three Color Theory

Answer 5

Young-Helmholtz Trichromatic Theory

Question 6

Retina contains what 3 color receptors

Answer 6

Red, Green, Blue-Sensitive

Question 7

When you have less short wave cones which is why you see red, yellow, and green better than blue

Answer 7

Color Blindness

Question 8

Color vision depends on pairs of opposing retinal processing in the brain

Answer 8

Opponent Processing Theory

Question 9

In the Opponent Processing Theory, match the colors
Red:
Blue:
Black

Answer 9

Green
Yellow
White

Question 10

Perception that familiar objects have consistent color despite changes in illumination that shift the wavelengths they reflect

Answer 10

Color Constancy

Question 11

Sense of hearing

Answer 11

Audition

Question 12

Sound that is determined by its frequency or number of complete wavelengths that can pass a point in time

Answer 12

Pitch

Question 13

Directly related to wavelength

Answer 13

Frequency

Question 14

The longer the waves, they produce what type of picth?

Answer 14

Lower Pitch

Question 15

The shorter the waves, the produce what type of pitch?

Answer 15

Higher Pitch

Question 16

Affects loudness meaning how much pressure is being forced through air

Answer 16

Amplitude

Question 17

Measured in decibels (dB)

Answer 17

Amplitude

Question 18

Number of wavelength cycles in a unit of time

Answer 18

Frequency

Question 19

Measured by hertz (Hz)

Answer 19

Frequency

Question 20

Funky shaped outer ear

Answer 20

Pinna

Question 21

Used to catch sound and direct it into the ear

Answer 21

Auditory Canal

Question 22

Also called the eardrum

Answer 22

Tympanic Membrane

Question 23

Vibrates when sound hits it

Answer 23

Tympanic Membrane

Question 24

Chamber between the eardrum and cochlea containing the ossicles of the three bones

Answer 24

Middle Ear

Question 25

Name the 3 bones:

Answer 25

1. Hammer
2. Anvil
3. Stirrup

Question 26

Contains the semicircular canals and the cochlea, which includes the recpetors and transducer sound energy into neural impulses

Answer 26

Inner Ear

Question 27

Contains vestibular sac, making the inner ear also important in balance

Answer 27

Inner Ear

Question 28

Coiled, bony, fluid-filled tube of the inner ear where the transduction of sound waves into neural impulses occur (snail shape)

Answer 28

Cochlea

Question 29

Inner surface of the cochlea that resonates the different sounds in different locations

Answer 29

Basilar Membrane

Question 30

Called hair cells, covers the basilar membrane

Answer 30

Organ of Corti

Question 31

When the fluid of the cochlea moves, the hair cells move to send signals to the basilar membrane and on to the auditory nerve

Answer 31

Organ of Corti

Question 32

States we hear different pitches because sound waves of various frequencies trigger activity at different places on the cochlea’s basilar membrane

Answer 32

Place Theory

Question 33

Maintains that the place of maximum vibration along the cochlea’s membrane is the basis of pitch disrimination

Answer 33

Place Theory

Question 34

Presume that the rate/frequency of nerve impulse in the auditory nerve matches the frequency of a tone, which gives us pitch

Answer 34

Frequency Theory
