CHAPTER 4!

Question 1

How do our senses relate to psychology

Answer 1

It is the way we take in information

Question 2

What are SENSATIONS

Answer 2

the stimulation of the sense organs

Question 3

What are our 5 senses

Answer 3

Vision, hearing, smelling, touching

Question 4

What is perception

Answer 4

Processing information, selection organization, and interpretation of sensory input.

Question 5

Light waves vary in….

Answer 5

Amplitude and wavelength

Question 6

The eye has two main purposes

Answer 6

-provide a house for neural tissue that receives light
-Channel light into the retina

Question 7

Retina

Answer 7

Neural tissue that lines the back of your eye and absorbs light to process images to send visual images to the brain

Question 8

Cornea

Answer 8

Clear think part of the eye, a transparent window where light enters

Question 9

Lens

Answer 9

Its job is to focus the image onto the retina

Question 10

Iris

Answer 10

Colored ring, and a muscle that adjusts the pupil

Question 11

pupil

Answer 11

Adjust how much light is coming in

Question 12

The sequence of where lights pass

Answer 12

Light passes through CORNEA first then the PUPIL then the LENS and then falls on the RETINA (objects flipped on the retina)

Question 13

Nearsightedness

Answer 13

Can see clearly in close range but everything behind is blurry

Question 14

Farsightedness

Answer 14

Can see clearly from afar but not near.

Question 15

The retina contains two types of receptors…

Answer 15

Rods and cones

Question 16

Rods

Answer 16

allow you to see at night

Question 17

cones

Answer 17

sensitive to daylight vision, and color

Question 18

How does visual information get to the brain?

Answer 18

Axon, Optic nerve, Thalamus relays to the occipital lobe.

Question 19

Reversible Image

Answer 19

A reversible image is a visual that can be seen in two or more ways, like the Rubin vase (vase or faces) or the duck-rabbit illusion. It shows how perception depends on mental interpretation.

Question 20

Phi Phenomenon

Answer 20

Capturing/ tricking the eye into the illusion of movement when there isnt.

Question 21

Figure and Ground

Answer 21

The figure is what you focus on, and the ground is the background, like a vase or faces in the Rubin vase illusion.

Question 22

Two types of cues are used to make judgments of distance

Answer 22

Binocular Cues: Depth cues that require both eyes, like retinal disparity and convergence, help us perceive depth and distance.

Monocular Cues: Depth cues that only need one eye, like size, texture, and linear perspective, help us judge distance.

Question 23

EXTRA CREDIT QUESTION

Answer 23

Remember Leonardo Da Vinci

Question 24

Stimulus for the auditory system is

Answer 24

SOUNDWAVES, which are actually vibrations of molecules

Question 25

With light, characteristics of sound interact in sound perception and are characterized by...

Answer 25

Wave length (pitch), Amplitude (volume loudness), Purity

Question 26

External ear

Answer 26

Pinna, top cartridge part to collect sound waves (like a funnel)

Question 27

Middle ear

Answer 27

Anvil, hammer, stirrup

Question 28

Inner ear

Answer 28

Cochlea, filled with fluid, sound waves bounce off and collect that information to the temporal lobe.

Question 29

Taste

Answer 29

gustatory system: chemical substances that dissolve in our saliva

Question 30

Smell

Answer 30

The olfactory system, where chemical substances are dissolved in the mucus of the nose.

Question 31

Touch

Answer 31

Mechanical and thermal energy that is applied to the skin, is relayed to the spinal collum and brain stem

Question 32

How are pain signals blocked

Answer 32

A spinal "gate" controls pain signals, blocking or allowing them to reach the brain based on factors like attention or emotions. (epidural)

Question 33

Sensory deprivation

Answer 33

Gradual decline in sensitivity to prolonged stimulation (earings, watches, rings)
