1

Sensation

raw data we recieve from our senses

New cards
2

Perception

process of interpreting the information we recieve from our senses

New cards
3

Gestalt psychology

Field of psychology that looks at human mind and behavior as a whole.

New cards
4

Gestalt principles

Figure and Ground

Continuation

Closure

Similarity

Proximity

Symmetry

New cards
5

Figure and Ground

Tendency of our visual system to place some objects into focus and others in the background

New cards
6

Continuation

Tendency of our visual system to percieve objects in smooth patterns, even if they are separate objects

New cards
7

Closure

Tendency of our visual system to automatically fill in the gaps and see whole objects, even when they are not complete.

New cards
8

Similarity

When objects look similar, we group them together and characterize them as one thing.

New cards
9

Proximity

Principle that when we see objects that are close together, we group them together.

New cards
10

Symmetry

When separate objects are organized around a center, we will perceive them as one object.

New cards
11

Depth perception

Ability to see relative distance of objects in our visual field.

New cards
12

Binocular cues

Information recieved from both eyes that help inform the brain about how far an object is from a person.

New cards
13

Monocular cues

Information about the distance of an object that is obtained with only one eye.

New cards
14

Relative size

Objects that are closer to us appear larger, while objects that are farther away appear smaller.

New cards
15

Interposition

When objects are blocked by other objects they’re farther away, but if the object is blocking another object, it’s closer.

New cards
16

Relative height cue

Objects that are higher appear to be farther away, while objects that are lower appear to be closer

New cards
17

Shading and contour

An object that has more detail appears to be closer, and an object that has less detail seems to be farther.

New cards
18

Linear perspective

When parallel lines appear to converge at a point in the distance, this helps us understand our positioning and depth.

New cards
19

Motion parallax

Objects closer to you appear to be moving faster, while objects farther away seem to be moving slower.

New cards
20

Signal detection theory

Predicts if you will percieve a weak signal

New cards
21

Absolute threshold

Weakest signal that alerts the senses.

New cards
22

Sensory Adaptation

When a stimulus is prolonged, our body’s are no longer conscious to it.

New cards
23

Habituation

When a stimulus is repeated continuously, it begins to lose it’s effect

New cards
24

Difference threshold

Minimum amount of change between two stimuli to be percieved as different

New cards
25

Weber Fechner

To notice a difference in stimuli, the stimuli must change by a constant percent, not a constant amount.

New cards
26

Size constancy

The tendency of the brain to perceive objects as the same size

New cards
27

Color constancy

The tendency of the brain to perceive objects as the same color

New cards
28

Shape constancy

The tendency of the brain to perceive objects as the same shape, even if its moving

New cards
29

Lightness constancy

The perception of blackness, whiteness and grayness of an object

New cards
30

Perceptual Set

A predisposition to perceive things a certain way.

New cards
31

Schema

A collection of basic knowledge that guides the perception of situation

New cards
32

Sclera

White tissue that forms the eye, outside layer

New cards
33

Cornea

Transparent, protects eye, allows light to bend and focuses vision

New cards
34

Aqueous humor

Made up of water and salt, helps maintain pressure in the eye and provides nourishment

New cards
35

Iris

Ring shaped membrane behind cornea - determines eye color and controls how much light enters the eye by contracting or expanding

New cards
36

Pupil

Dark part of eye, hole that light goes through.

New cards
37

Lens

Allows for eye to change focus, curved on both ends

New cards
38

Vitreous Humor

Clear gel like fluid in the vitreous cavity, between lens and retina

New cards
39

Retina

Located in the back of the eye, made up of photoreceptors that convert light into neural impulses.

New cards
40

Choroid

Supports cells in the eye by providing oxygen from blood vessels

New cards
41

Optic Nerve

Neural impulses travel through this to the brain to provide vision

New cards
42

rods

perceive black and white

New cards
43

cones

perceive color

New cards
44

Astigmatism

Occurs if the cornea is irregularly shaped and could impact one’s ability to focus

New cards
45

Cataracts

Lens of the eye becomes cloudy, so vision becomes blurry

New cards
46

Trichromatic Theory

Different wavelengths of light stimulate combinations of three different color receptors - red, green and blue

New cards
47

Opponent Processing Theory

States that information from cones is sent to ganglion cells, activates 3 color pairings - red-green, blue-yellow, black-white

New cards
48

Achromatism

Condition where you can only see black, white, and gray

New cards
49

Dichromatism

Type of color blindness where one is missing one of the three cone pigments

New cards
50

Synesthesia

Medical condition where stimulation of one sense also elicits another sense to fire.

New cards
51

Top-Down Processing

Using prior knowledge to interpret information you are perceiving

New cards
52

Bottom-Up Processing

When you interpret information that is unfamiliar by examining it as is

New cards
53

Kinesthesis

The sensory information that allows us to control our movements through our sensory receptors in the muscles and joints of the body

New cards
54

Proprioceptors

Sensory receptors in our body that are sensitive to our body’s movements and positions

New cards
55

Vestibular sense

Our sense of balance that is enabled by the vestibular canals of the ear

New cards
56

Sensory interaction

How our senses interact to help us perceive the world
