Sensation and perception

Question 1

Tendency to pay less attention to a source of stimulation that is non-changing

Answer 1

sensory adaptation

Question 2

Smallest amount of stimulus that can be detected at least 50% of the time

Answer 2

absolute threshold

Question 3

suggests we have different color channels in which activation of one color in each pair inhibits the other color

Answer 3

opponent process theory

Question 4

Sensitive to dim light and excel at seeing in dim lighting

Answer 4

rods

Question 5

Area of retina where vision is clearest. Contains only cones

Answer 5

fovea

Question 6

Opening to allow light into the eye

Answer 6

pupil

Question 7

crosses info closest to the nose over to the opposite hemisphere of the brain

Answer 7

optic chiasm

Question 8

Smallest detectable difference between two stimuli that can be detected at least 50% of the time

Answer 8

difference threshold

Question 9

Infant vision

Answer 9

see everything adults see but with less detail, therefore prefer more contrast

Question 10

bundle of axons at the back of the eye carrying visual info to the brain. Blind spot

Answer 10

optic nerve

Question 11

shortened eyeballs interfere with vision for close up objects

Answer 11

faresightedness

Question 12

Taking in info and using previous knowledge, expectations, etc. to process

Answer 12

Top-down

Question 13

explains colorblindness

Answer 13

trichromatic theory

Question 14

Studying the relationship between stimuli and perception of those stimuli

Answer 14

Psychophysics

Question 15

The stronger the baseline stimulus, the bigger the change needed to notice a difference

Answer 15

weber’s law

Question 16

Muscle that controls the pupil

Answer 16

iris

Question 17

surface of cornea is uneven leading to blurry vision

Answer 17

astigmatism

Question 18

Taking in info as is and processing

Answer 18

Bottom-up

Question 19

rely on both eyes

Answer 19

binocular depth cues

Question 20

suggests there are 3 types of cones that respond to short (blue), medium (green), and long (red) wavelengths of light

Answer 20

trichromatic theory

Question 21

Track processed light takes

Answer 21

optic nerve, optic chiasm, optic tracts, thalamus, and occipital lobe

Question 22

explains after images

Answer 22

opponent process theory

Question 23

The actual intensity of the stimulus and the individual observer’s criteria for deciding whether the stimulus occurred

Answer 23

signal detection

Question 24

built in tendencies to organize sensory information in certain ways

Answer 24

gestalt psychology

Question 25

Bends light to begin forming an image on the retina

Answer 25

cornea

Question 26

rely on one eye

Answer 26

monocular depth cues

Question 27

L and R eyes transmit different information for near objects

Answer 27

Retinal disparity. Binocular depth cue

Question 28

Translating sensory info into neural signals or messages

Answer 28

transduction

Question 29

monocular depth cues

Answer 29

linear perspective, texture, shading/highlighting, occlusion, relative size

Question 30

carry visual info from the optic chiasm to the thalamus, hypothalamus, and midbrian

Answer 30

optic tracts

Question 31

Network of specialized photoreceptors that process light

Answer 31

retina

Question 32

cultural differences with vision

Answer 32

muller-lyer less common in African and Filipino. Americans look at figure and Chinese look at figure and ground evenly

Question 33

Detect color, operate under normal daylight conditions, and allow us to focus on fine detail

Answer 33

cones

Question 34

Parallel lines look different sizes bc of other lines in the picture but theyre really the same size

Answer 34

ponzo illusion

Question 35

elongated eyeballs interfere with vision for distant objects

Answer 35

nearsightedness

Question 36

We develop a perception for what lines are larger based on a picture even though they’re the same. Deals with architecture

lens
