TERM 1
sensation
DEFINITION 1
process by which our sensory receptors and nervous system
receive and present stimulus energy from our environment
TERM 2
perception
DEFINITION 2
Perception is the process of attaining awareness or
understanding of the environment by organizing and
interpreting sensory information.
TERM 3
bottom-up processing
DEFINITION 3
analysis that begins with the sensory receptors and works up
to the brains integration of sensory information
TERM 4

sensation

process by which our sensory receptors and nervous system receive and present stimulus energy from our environment TERM 2

perception

DEFINITION 2 Perception is the process of attaining awareness or understanding of the environment by organizing and interpreting sensory information. TERM 3

bottom-up processing

DEFINITION 3 analysis that begins with the sensory receptors and works up to the brains integration of sensory information TERM 4

top-down processing

DEFINITION 4 information processing guided by higher level mental processes as when we construct perceptions drawing on our experience and expectations TERM 5

absolute threshold

DEFINITION 5 minimum stimulation needed to detect a particular stimulus 50% of the time

difference threshold

the smallest detectable difference between two stimuli required for detection 50% of the time-just noticeable difference TERM 7

signal detection theory

DEFINITION 7 predicts how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise)- assumes that there is no single absolute threshold-detection depends partly on person'sexperience, expectations, motivation, and level of fatigueAKA AIRPORT SECURITY DETECTOR TERM 8

subliminal perception and persuasion

DEFINITION 8 below ones absolute threshold for conscious awareness TERM 9

Weber's law

DEFINITION 9 two stimuli must differ by a constant minimum percentage (rather than a constant amount) to be perceived as different- one pound plus one pound is more noticeable than one pound plus one thousand pounds TERM 10

sensory adaptation

DEFINITION 10 diminished sensitivity that happens when we become "used to" a constant stimulus

fovea

The fovea centralis, also generally known as the fovea, is a part of the eye, located in the center of the macula region of the retina. TERM 17

accommodation

DEFINITION 17 what the lens of the eyeball does/changes TERM 18

rods

DEFINITION 18 120 million in the eyeperipheral reinadetect BLACK AND WHITE GRAYtwilight or low light TERM 19

cones

DEFINITION 19 ned more light, higher absolute threshold6 million in the eyenear the center of the retina (fovea)fine detail and color visiondaylight or well-light conditions TERM 20

optic nerve

DEFINITION 20 nerves that carries neural impulses from eye to brain

blind spot

A blind spot, also known as a scotoma, is an obscuration of the visual field. TERM 22

feature detectors

DEFINITION 22 nerve cells in the brain that respond to specific features- shape-angle-movementILLUSIONS TERM 23

parallel processing

DEFINITION 23 Parallel processing is the ability to carry out multiple operations or tasks simultaneously. -VISION CAN MULI TASK WITHOUT REALLY REALIZING TERM 24

Young-Helmholz Trichromatic theory

DEFINITION 24 Proposed that the eye detects 3 primary colors of light: RED BLUE AND GREEN all others can be derived by combining these three TERM 25

opponent-process theory

DEFINITION 25 theory of color vision that suggests colors compete assumes that the visual system treats pairs of colors as opposing or antagonistic. Opponent- process cells are inhibited by a color, and have a burst of activity when it is removed-FLAGS

place theory

the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated TERM 32

frequency theory

DEFINITION 32 the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense is pitch TERM 33

conduction hearing loss

DEFINITION 33 damage to the ossicles (hammer anvil stirrup) or eardrum TERM 34

sensorineural hearing loss

DEFINITION 34 hearing loss caused by damage to the cochlea's receptors cells (basilar membrane) or to the auditory nerve TERM 35

gate control theory

DEFINITION 35 theory that the spinal cord contains a neurological "gate" that blocks pain signals or allows them to pass on to the brain-"gate" opened by the activity of pain signals traveling up small nerve fibers-"gate" closed by activity in larger fibers or by info entering the brain

neuromatrix theory of pain

theory that the matrix of neurons in the brain is capable of generating pain (and other sensations) in the absence of signals from sensory nerves phantom limb sensation TERM 37

sensory

interaction

DEFINITION 37 principal that one sense may influence anotherSMELL OF FOOD INFLUENCING TASTEWHEN YOU HAVE A COLD YOU CANT TASTE TERM 38

gustation

DEFINITION 38 Taste TERM 39

olfaction

DEFINITION 39 smell TERM 40

olfactory bulb

DEFINITION 40 processes smell
