Sensation

Question 1

Sensation

Answer 1

the brain receives input from the sensory organs on surrounding space

Transduction

Answer 2

transforming cell stimulation into neural impulses

Question 3

Just Noticeable Difference

Answer 7

when someone can just be able tell the difference between two almost identical items

Question 8

Weber’s Law

central point of focus and detail

Question 15

Lens

Answer 15

focuses and flips

Question 16

Cornea

Answer 16

bends light and protects eye

Question 17

Iris

Answer 17

colored muscle and helps dilate or constrict pupil

Question 18

Pupil

Answer 18

opening of eye

Question 19

visual/optic nerve

Answer 19

transmit visual information to thalamus and visual cortex

Question 20

Accommodation

Answer 20

lens can change shape to focus on near or far objects

Question 21

Blind Spot

Answer 21

area in eye with no visual field, no receptor cells where optic nerve leaves eye

Question 22

Young Helmholtz Trichromatic Theory

Answer 22

three different types of receptor cones in eye that respond to different wavelengths, red(long), green(medium), and blue(short)

Question 23

Opponent Process Theory

Answer 23

neural process of receiving colors as opposite; white and black, green and red, and blue and yellow

Question 24

Afterimages

Answer 24

when ganglion cells become overstimulated you see the opposite colors afterward

Question 25

Dichromatism/monochromatism

Answer 25

color blind; when one or two of your cones are missing

Question 26

Occipital lobes

Answer 26

receive visual information

Question 27

Nearsightedness

Answer 27

can focus/see things near but not far

Question 28

Farsightedness

Answer 28

can see/focus on things far but not near

Question 29

Prosopagnosia

Answer 29

face blindness

Question 30

Blindsight

Answer 30

can't see but respond to things like you can see

Question 31

Wavelength

Answer 31

vision- color; hearing- pitch

Question 32

Amplitude

Answer 32

vision- brightness; hearing-loudness

Question 33

Conduction Hearing Loss

Answer 33

when the middle of the ear is not conducting sound to cochlea well

Question 34

Sensorineural Hearing Loss

Answer 34

when the receptor cells aren't sending messages through auditory nerves

Question 35

Place Theory

Answer 35

high frequency pitches; high vibrations are at front of cochlea and low frequencies at the back

Question 36

Frequency Theory

Answer 36

low frequency pitches; sound frequencies send signals at whatever rate the sound is received

Question 37

Volley Principle

Answer 37

medium frequency pitches; one neuron fires and then send to different neuron to fire and send back and forth to each other

Question 38

Sound localization

Answer 38

brain can direct where sound is coming from

Question 39

Olfaction

Answer 39

smell

Question 40

Gustation

Answer 40

taste

Question 41

Thalamus

Answer 41

where all sensory information is sent except for smell

Question 42

Pheromones

Answer 42

a scent that is left for communicating (usually for animals)

Question 43

Gustatory cells

Answer 43

taste receptors, 6 different kinds: sweet, sour, bitter, salty, umami, oleogustus

Question 44

Taste receptors

Answer 44

project hairs into taste buds to taste, and send information to gustatory cortex

Question 45

Supertasters

Answer 45

a lot of little bumps on tongue, has intricate sense of taste

Question 46

Medium Taster

Answer 46

regular amount of bumps, normal sense of taste

Question 47

Non-taster

Answer 47

not a lot of bumps on tongue, cannot taste very many things

Question 48

Hot/Cold sensation

Answer 48

when you have cold and pressure you feel wet and when it goes from cold to hot you feel searing

Question 49

Gate-Control Theory

Answer 49

gate can be opened by small nerve fibers to send pain signals to brain and can be closed by large ones to stop sending signals

Question 50

Phantom Limb Sensation

Answer 50

when you do not have a limb but still get sensations and pain as if it were still on your body

Question 51

Vestibular Sense

Answer 51

ability to sense position of body and be able to balance

Question 52

Semicircular canals

Answer 52

fluid chambers by in inner ear to send messages to cerebellum about body position

Question 53

Kinesthesis

Answer 53

sensing and coordination of individual body parts
