Sensations

Question 0

Bottom-up processing

Answer 0

Processing of information from sensory organs

Forming images from eyes

Question 1

Sensation

Answer 1

How we receive information about the world around us

Sights sounds touch

Question 2

Perception

Answer 2

Our complete analysis of information recieved

Perception that you are looking at the sky

Question 3

Top-down processing

Answer 3

Interprets information using past experiences and your expectations

Knowing from the past that what you are looking at is a ball

Question 4

Absolute threshold

Answer 4

The minimum amount of stimulation needed to detect a certain stimulus.

The maker of perfume uses this to add or not add certain fragrances and how much.

Question 5

Difference threshold

Answer 5

The least amount of change that a person can detect.

How long it takes for you to detect the light changing when dimming lights very slowly

Question 6

Signal detection theory

Answer 6

Formulas or principles that predict how we will detect faint stimulus, and background stimulus.

Thinking you saw a bird when it was an inanimate object

Question 7

Sensory adaptation

Answer 7

Failing to notice a constant and unchanging stimulus

Getting used to cold water and not noticing it

Question 8

Selective attention

Answer 8

Focusing on one stimulus and ignore everything else

Getting so caught up in a book that all other sights and sounds disappear

Question 9

Electromagnetic therapy

Answer 9

Way light enters the eyes and present electromagnetic radiation in environment

The visible light spectrum

Question 10

Hue

Answer 10

Color of light determined by wave length and light energy

Red or orange colors

Question 11

Cornea

Answer 11

Clear curved bulge on the front of the eye

Bends light waves

Question 12

Iris

Answer 12

The colored tissue behind the cornea

Regulates size of pupil

Question 13

Pupil

Answer 13

Center of the iris, controls amount of light entering the eye

Small to let less light in like when in bright sunlight, and large to let more in like when in the dark

Question 14

Lens

Answer 14

Transparent structure behind the eye, changes thickness to focus on image

Question 15

Retina

Answer 15

Processing center at the back of the eye

The film of the camera

Question 16

Receptor cells

Answer 16

Change light energy into nerve impulses for the brain to interpret

Interpreter for a foreign speaking person

Question 17

Rods

Answer 17

Detect only black and white and shades of gray

Respond only in dim light and like a night vision

Question 18

Cones

Answer 18

Detect sharp detail and colors, cluster in the center of the retina

Like the hd effect

Question 19

Fovea

Answer 19

Center of retina, where vision is the best

Where the cones cluster

Question 20

Bipolar cells

Answer 20

Cells that form the middle layer in retina

A review that is taken up to be looked at and passed used later

Question 21

Ganglion cells

Answer 21

Top layer of cells in retina that transmit information from bipolar cells through their axons.

Telephone wire

Question 22

Optic nerve

Answer 22

Nerve that sends information from eye to occipital lobe in brain

Telephone wire

Question 23

Blind spot

Answer 23

Where the optic nerve exits the eye due to no cones or rods

Like on a car

Question 24

Trichromatic theory

Answer 24

Cones tuned to detect blue, red, and green light and that different levels of stimulus create many different combinations of these three colors to create many more different colors from the original three Like when mixing colors to make more

Question 25

Opponent process theory

Answer 25

Color is processed in opposite pairs like black and white pair, and light that stimulates one half hides or reduces the other half. Like only seeing one half of the moon and the other being dark

Question 26

Pitch

Answer 26

The highness or lowness of a sound depending on the frequency Like singing

Question 27

Hertz

Answer 27

Number of sound wave peaks per second, or frequency, of a sound wave Like when glass shatters from singing

Question 28

Decibel

Answer 28

A measure of the hight of a sound wave which determines loudness of sound A whisper has low decibel and a fire truck siren has high decibels

Question 29

Auditory canal

Answer 29

Opening sound waves travel into ear for processing Metal, unprocessed being put on conveyor belt

Question 30

Eardrum

Answer 30

Tissue barrier at end of auditory canal transfers sound vibration from air to three tiny bones Like a drum

Question 31

Ossicles

Answer 31

Three tiny bones that transfers sound waves from eardrum to cochlea Like structures that hold up buildings

Question 32

Cochlea

Answer 32

Snail shaped, bony, fluid filled structure in ear where sound waves are changed to neural impulses Like a balloon

Question 33

Oval window

Answer 33

On surface of cochlea receives sound vibrations from three tiny bones Like the canvas on drum

Question 34

Hair cells

Answer 34

Receptor cells located in cochlea and change sound waves to neural impulses Similar to the strings

Question 35

Auditory nerve

Answer 35

Nerve that carries sound information from ears to temporal lobe of the brain The strings on a violin

Question 36

Olfactory cells

Answer 36

Chemical receptor cells for smell, located in nasal passages Vacuum

Question 37

Kinesthetic senses

Answer 37

System for sensing position and movement of individual body parts Like the balancer on phone

Question 38

Vestibular senses

Answer 38

System for sensing body orientation and balance Like the balance on the phone
