Flashcards in Chapter 5 Part Two Deck (31):
1

Blind Spot

Where the optic nerve leaves the eye
No receptors

2

Fovea

Point of central focus - cluster of cones

3

Feature Detectors

Nerve cells that detect specific features such as shape, angle, or movement

4

Parallel Processing

Simultaneously processing several aspects of a problem or image
Allows us to multitask

5

Young-Helmholtz Trichromatic (three-color) Theory

Blue, red, green produces every color

6

Opponent-Process Theory

Opposing colors yellow/blue, white/black, red/green

7

Color Constancy

Difference in illumination still makes the color constant, but appear different

8

Audition

Sense or act of hearing

9

Frequency

Amplitude/loudness

10

Pitch

High and low sounds
Depends on frequency

11

Middle Ear

Amplifies sound

12

Cochlea

Coiled, fluid filled tube, triggers neural impulses

13

Inner Ear

Transduction of sound

14

Basilar Membrane

Where cilia are located

15

Place Theory

Link pitch(high) to place

16

Frequency Theory

Rate of impulses/matching cochlea/matches frequency in tone(low)

17

Conduction Hearing Loss

Damage to mechanical system that conducts waves

18

Sensorineural Hearing Loss

Damage to receptor cells (nerve deafness)
Cochlear implants can help

19

Cochlear Implant

Device that converts sounds
For sensorineural hearing loss

20

Gate-Control Theory

Spinal cord blocks pain and allows signals through

21

McGurk Effect

Auditory component of one sound is paired with the visual component of another sound, leading to the perception of a third sound.

22

Sensory Interaction

One sense may influence another - smell and taste

23

Sensory Compensation

When one sense is lost, other senses may be enhanced
Ex) blind musician may have perfect pitch

24

Kinesthesis

System for sensing position and movement of body parts

25

Vestibular Sense

Sense of movement and balance

26

Bipolar Cells

Specialized sensory neurons for the transmission of special senses
Activates the ganglion cells

27

Ganglion Cells

Receives visual info from photoreceptors
Activated by bipolar cells

28

Olfaction

Experiencing Sense of smell

29

Synesthesia

Where senses become joined/interact
Ex) hearing a sound and seeing a color

30

Cilia

Tiny hair cells lining the cochlea
Trigger sound waves are transduced into neural impulses

31

Optic Nerve

Nerve that carries impulses to the brain from the eyes
