body senses and perception Flashcards
what is kinesthesis?
feedback about the muscle and joint positions
receptors for this kinesthetic sense are?
nerve endings in muscles, joints and tendons
what does the vestibular system provide?
information related to the sense of balance or spatial orientation
what are the three semicircular canals that contain receptors for head movement?
left/right, backwards/forwards and up/down
what are vestibular sacs?
respond to body position, indicate upright or at an angle
what is bottom-up processing?
relatively automatic analysis of individual elements of stimulus which are combined into a unified whole
(typically relates to basic stimuli properties)
what is top-down processing?
modulating role of existing knowledge, concepts, ideas, expectations that affect how things are perceived and interpreted
(putting the pieces together and interpreting the meaning of them)
what are the two primary roles for attention?
focusing and filtering
what is inattentional blindness?
situations in which we fail to notice things that are right in front of us
what is change blindness?
situations in which we fail to notice what may be considered relatively obvious changes
many gestalt laws of perceptual organization predict how we perceive stimuli, what four factors does this include?
similarity, proximity, closure and continuity
what is similarity?
grouping by feature
what is proximity?
grouping by closeness
what is closure?
close/open edges, boundaries
what is continuity?
elements linked to form a continuous line
