Unit 4: Sensation And Perception

Front 1

What are the properties of light?

Back 1

Wavelength (color/hue), intensity(brightness), and purity (saturation)

Front 2

What is "Wave Length"?

Back 2

The distance between two consecutive crests or troughs of a wave

Front 3

Which colors represent the longest and shortest wavelengths?

Back 3

Red-longest, Violet-shortest

Front 4

What is "Amplitude"?

Back 4

The height of a wave

Front 5

What is the "Trichromat" Theory?

Back 5

Created by Young Helmholtz- states that the

three cones correspond to red, blue and green-other colors perceived through mixing signals of cones

Front 6

How do sensations become perceptions?

Back 6

Transduction of external stimuli sent to brain, which makes sense of it all!

Front 7

In what lobe are faces percieved in?

Back 7

The right temperal lobe

Front 8

What is the relation betw. sight, sound, and vestibular sense?

Back 8

Eyes detect changes in body posture and vestibular imbalance (in ears) provide info to keep us right side up!

Front 9

How do sight and taste differ from sight and sound?

Back 9

Chemical molecules, not physical energy

Front 10

What is the formal word for taste buds?

Back 10

Fungiform Papallia

Front 11

Where are taste buds located?

Back 11

In Papillae-Tongue, throat, soft palate, chemical receptors, parietal lobe

Front 12

What is a "Volatile Substance"?

Back 12

Chemical molecules released into air at room temp

Front 13

What is the Olfactory Bulb in the Nose?

Back 13

receptor cells covered in mucus that dissolve molecules into electric signals and send to bulb

Front 14

What is the "Olfactory Nerve"?

Back 14

Transmits neural impulses to amygdala and hippocampus

Front 15

What are "Pheromones"?

Back 15

Chemical communicators system that affects behavior of others

Front 16

What are "Skin Senses"?

Back 16

sense of touch emcompasses pressure, pain, and temp(cold/warm)

Front 17

Where are receptors located?

Back 17

middle layer of skin

Front 18

What is the "Two Point Threshold"?

Back 18

Smallest distance betw. two points before person identifies two sources of stimulation as one (toothpick demo)

Front 19

What is the "Gate Theory"?

Back 19

Signal must travel through gate in spinal cord to recieve pain

Front 20

What is the Phantom Limb Pain?

Back 20

Pain coming from an amputated limb caused by memory or nerves in the stump

Front 21

What is the Ganzfield Effect?

Back 21

caused by exposure to unstructured environment

Front 22

Characteristics of Extra-Sensory Perception?

Back 22

a mental perception of events through means other than senses (telepathy, clairvoyance, precognition, Zener cards)

Front 23

Characteristics of Psychokinesis?

Back 23

Influence of mind over physical matter(static, catching arrow in mid air, living miracle(heal you!))

Front 24

Where are sense receptors located for vision?

Back 24

Retina(rods and cones)

Front 25

Where are sense receptors located for audition?

Back 25

cochlea, basillar membrane(organ of the corti)

Front 26

Where are sense receptors located for olfaction?

Back 26

nasal membrane

Front 27

Where are sense receptors located for gustation?

Back 27

Taste buds

Front 28

Where are sense receptors located for skin?

Back 28

hair follicles or free nerve endings

Front 29

Where are sense receptors located for vestibular?

Back 29

Semi Circular Canals

Front 30

Where are sense receptors located for kinesthetic?

Back 30

in muscles, joints, tendents
