Sensation
|
The sense organ's detection of external stimulus, their response, and the transmission of these responses to the brain
|
|
Perception
|
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 |
|
Perception pathway
|
Has sensory receptors, connecting neuron transmit information to the brain= thalamus
Thalamus sends information to the primary sensory cortex where impulse is interpreted |
|
Sensory receptors
|
Specialize receptor sounds that detect specific physical or chemical stimulation; past the resulting impulses to connecting neurons
|
|
sensory thresholds: absolute threshold
|
The minimum intensity of stimulation that occurs before you express a sensation.
1. stimuli correctly detected percent of the time |
|
Signal detection theory(STD)
|
Detection of a faint stimulus requires a judgment based on a subjective interpretation of ambiguous information.
For possible judgments: see graph |
|
bottom up-processing
|
Perception based on physical features of the stimulus.
EX) listening to music, seeing hearing, or experiencing something |
|
top– Down processing
|
How knowledge, expectations, or past experiences shake that interpretation of sensory information.
1. thinking based on past experiences and expectations EX) chopped |
|
audition
|
The sense of sound
|
|
pupil
|
Determine how much light enters eye; People size depends upon iris
|
|
Retina
|
Contains sensory receptors for light
|
|
Rods |
Sensory cells that respond to low levels of illimination; resulting in black-and-white perception
|
|
cones
|
Sensory cells that respond to higher levels of illumination; resulting color vision and detail
|
|
Vestibular sense
|
Perception of bounds determined by receptors in the inner ear, sense of balance
|
|
Pain is what?
|
Adaptive
|
|
fast fibers
|
Sharp, fast pain; useful for immediate production
|
|
slow fibers
|
Chronic, doll, study pain; useful for recuperation
