Sensation To Perception

Front 1

Sensation

Back 1

The sense organ's detection of external stimulus, their response, and the transmission of these responses to the brain

Front 2

Perception

Back 2

The brains processing organization and interpretation of sensory signal; results in internal representations of the stimuli that forms and conscious experience of the world.

See example on paper

Front 3

Perception pathway

Back 3

Has sensory receptors, connecting neuron transmit information to the brain= thalamus

Thalamus sends information to the primary sensory cortex where impulse is interpreted

Front 4

Sensory receptors

Back 4

Specialize receptor sounds that detect specific physical or chemical stimulation; past the resulting impulses to connecting neurons

Front 5

sensory thresholds: absolute threshold

Back 5

The minimum intensity of stimulation that occurs before you express a sensation.

1. stimuli correctly detected percent of the time

Front 6

Signal detection theory(STD)

Back 6

Detection of a faint stimulus requires a judgment based on a subjective interpretation of ambiguous information.

For possible judgments: see graph

Front 7

bottom up-processing

Back 7

Perception based on physical features of the stimulus.

EX) listening to music, seeing hearing, or experiencing something

Front 8

top– Down processing

Back 8

How knowledge, expectations, or past experiences shake that interpretation of sensory information.

1. thinking based on past experiences and expectations

EX) chopped

Front 9

audition

Back 9

The sense of sound

Front 10

pupil

Back 10

Determine how much light enters eye; People size depends upon iris

Front 11

Retina

Back 11

Contains sensory receptors for light

Front 12

Rods

Back 12

Sensory cells that respond to low levels of illimination; resulting in black-and-white perception

Front 13

cones

Back 13

Sensory cells that respond to higher levels of illumination; resulting color vision and detail

Front 14

Vestibular sense

Back 14

Perception of bounds determined by receptors in the inner ear, sense of balance

Front 15

Pain is what?

Back 15

Adaptive

Front 16

fast fibers

Back 16

Sharp, fast pain; useful for immediate production

Front 17

slow fibers

Back 17

Chronic, doll, study pain; useful for recuperation
