Sensory Contribution (Chapter 5)

Question 1

what is visual search?

Answer 1

scanning the environment to see relevant cues

Question 2

what is quiet eye research?

Answer 2

the final fixation on a target before before initiation if the movement

Question 3

what is a sensory conflict?

Answer 3

when there is a blockage/break between your vision and proprioception.

ex: closing eyes to raise certain finger

Question 4

what is focal vision?

Answer 4

voluntary, conscious and front central vision area

affected by light

Question 5

what is ambient vision?

Answer 5

subconscious, helps spatial localization and orientation, central and peripheral fields

not affected by light

Question 6

what is proprioception?

Answer 6

continuous flow of sensory info recieved from all receptors that communicates info about body position and movement

Question 7

what are golgi tendons?

Answer 7

where tendons attach to muscle, communicates how much tension is used.

Question 8

what are muscle splindles?

Answer 8

located between muscle fibres in the belly of a muscle

tells how much and how fast muscle length is changing

Question 9

what are joint kinesthetic receptors?

Answer 9

within a joint structure, provides information on if action is too slow, too fast, or wrong direction

Question 10

what is vestibular apparatus?

Answer 10

collection of receptors in the inner ear, communicates on balance and posture

Question 11

what are afferent (sensory) pathways?

Answer 11

carries signal to brain

Question 12

what are efferent (motor) pathways?

Answer 12

sends signals to muscles to move

Question 13

what is a monosynaptic reflex?

Answer 13

only one synapse (motor neuron) triggered

Question 14

what is a polysynaptic reflex?

Answer 14

more than one synapse (interneuron) is triggered

ex: hot stove, move more muscles

Question 15

what is/ the function of the cerebrum/cerebral cortex- sensory area?

Answer 15

sensory area interprets information from sensory receptors

ex: touch, pressure, temperature

Question 16

what is/ the function of the cerebrum/cerebral cortex motor area?

Answer 16

coordinate and initiate voluntary movements of muscles fine motor, and decides order and degree of muscles to contract

Question 17

what is/ the function of the cerebrum/cerebral cortex associated areas?

Answer 17

analysis and interpertation of sensory information, new sensory inputs are associated with the past

Question 18

what is the function of the cerebellum?

Answer 18

monitors intended movement with actual movement taking place.

compares can error detect and correct.

Question 19

what is the function of basal ganglia?

Answer 19

initiation, control anf monitor intensity of subconscious movement

ex: swinging arms when walking

Question 20

what are 3 memory systems?

Answer 20

1) sensory memory
2) working memory
3) long term memory

Question 21

what are the 2 functions of working memory?

Answer 21

1) phonological loop
2) visuospatial sketchpad

Question 22

what is phonological loop?

Answer 22

short term storage of written and spoken

Question 23

what is visuospatial sketchpad?

Answer 23

tempory storage of spatial and visual
