Sensory Contribution (Chapter 5) Flashcards
what is visual search?
scanning the environment to see relevant cues
what is quiet eye research?
the final fixation on a target before before initiation if the movement
what is a sensory conflict?
when there is a blockage/break between your vision and proprioception.
ex: closing eyes to raise certain finger
what is focal vision?
voluntary, conscious and front central vision area
affected by light
what is ambient vision?
subconscious, helps spatial localization and orientation, central and peripheral fields
not affected by light
what is proprioception?
continuous flow of sensory info recieved from all receptors that communicates info about body position and movement
what are golgi tendons?
where tendons attach to muscle, communicates how much tension is used.
what are muscle splindles?
located between muscle fibres in the belly of a muscle
tells how much and how fast muscle length is changing
what are joint kinesthetic receptors?
within a joint structure, provides information on if action is too slow, too fast, or wrong direction
what is vestibular apparatus?
collection of receptors in the inner ear, communicates on balance and posture
what are afferent (sensory) pathways?
carries signal to brain
what are efferent (motor) pathways?
sends signals to muscles to move
what is a monosynaptic reflex?
only one synapse (motor neuron) triggered
what is a polysynaptic reflex?
more than one synapse (interneuron) is triggered
ex: hot stove, move more muscles
what is/ the function of the cerebrum/cerebral cortex- sensory area?
sensory area interprets information from sensory receptors
ex: touch, pressure, temperature
what is/ the function of the cerebrum/cerebral cortex motor area?
coordinate and initiate voluntary movements of muscles fine motor, and decides order and degree of muscles to contract
what is/ the function of the cerebrum/cerebral cortex associated areas?
analysis and interpertation of sensory information, new sensory inputs are associated with the past
what is the function of the cerebellum?
monitors intended movement with actual movement taking place.
compares can error detect and correct.
what is the function of basal ganglia?
initiation, control anf monitor intensity of subconscious movement
ex: swinging arms when walking
what are 3 memory systems?
1) sensory memory
2) working memory
3) long term memory
what are the 2 functions of working memory?
1) phonological loop
2) visuospatial sketchpad
what is phonological loop?
short term storage of written and spoken
what is visuospatial sketchpad?
tempory storage of spatial and visual
