Thermoreceptor

Info regarding temp is processed by _______ cell in the skin

2

illusions

Visual__________occur because stimuli in the environment consistently produce errors in our perception

3

disparity

The difference between the images in the two eyes or the ________ is the binocular cue the brain uses to determine the depth or distance of an object

4

Weber's law

What law of psycho-physics states that two stimuli must differ by a constant minimum percentage (rather than a constant amount) to be perceived as different?

5

Sensation is the initial activation of the sense organs

perception is the processing of the information from those organs in the brain

6

movement

The perception that a stationary object is moving is called apparent__________

7

Pain

is the sensation that warns us of damage to our bodies

8

protects the lens of the eye

Cornea does

9

The smallest change in stimulation needed in order to discriminate one stimulus from another

The difference theshold is

10

kinesthetic

senses provide informaiton about movement, posture and orientation

11

Depth

perception is the ability to perceive objects 3-dimensionally

12

nose

is an active instrument and we actively sniff when we are trying to track the source of an object of interest

13

perception

the sorting out, interpretation, analysis and integration of stimuli by the sense organs and the brain is called_______

14

sclera

is the white, outer part of the eye that helps to maintain the shape of the eye and to protect it from injury

15

Gestalt perspective

includes the principle that the whole is different from the sun of its parts

16

Cones

are receptor cells contained in the retina and are useful in color perception, particularly in bright light conditions

17

vestibular

sense provides information about balance and movement

18

thermoreceptor

information regarding temp is processed by ____________cells in the skin

19

Visual cortex

processes sensory information from the eyes in the occipital lob of the brain

20

familiar size, linear perspective, and texure gradient

are monocular cues that help with depth perception

21

Light

is a form od electromagnetic energy that can be described in terms of wavelengths

22

Size, shape and color

3 types of perceptual constancy

23

Sensation, perception

Specialized receptor cells inthe sense organs detect stimuli from the environment. This is called ______________. The brain then gives meaning to the stimuli, which is called ____________

24

Apparent movement

the perception that a stationary object is moving

25

pupils

adjust the amount of light reaching the retina

26

opponent-process

theory of color vision outlines how receptor cells for color vision are linked in pairs

27

Top-down processing

begins with the higher levels of the brain

28

bottom-up processing

processing that is initiated by sensory information about the external environment

29

Shading

is the monocular cue that involves changes in perception due to the position of the light and the position of the viewer

30

Trichromatic

the presence of "afterimages" cannot be explained by the ________ theory of color vision

31

Rods

are important in low light

32

Sensory receptors

take information from the environment, creating local electrical currents. The receptors trigger action potentials in sensory neurons, which carry the information to the central nervous system

33

trichromatic

theory of color vision outlines three types of cones that work together to form color vision

34

Warm and cold

are two types of thermoreceptors

35

Bottom-up

processing that commences with sensory receptors registering environmental information and spending it to the brain for analysis and interpretation is known as
