unit 20 and 21 week 10 Flashcards
reflex response is called
a reflex arc
what are the neurons that send info from sensors to cns
afferent neurons
what neurons send signal from cns to the body
efferent neruons
what happens in the case of a blink reflex
rods and cones are sensors and the muscles that control the eyelids are where the efferent neurons signal
what happens when the tendon in the quad muscle is tapped
muscle is streched and muscle spindles respond to the stretch with an increase in AP
- this goes to the spine
- efferent signal back to muscle axons
- muscle contracts
what causes the reflex/muscle contraction
the increase in the number of ap in afferent axons
causes motor neurons to fire ap and excite and contract stretched muscle
describe the legs in the patellar reflex test
crossed
what is the consensual light reflex
hold a hand or book in front of face and shine light on one half
what is the determination of eye preference test
card with a hole and see which eye is dominant for finding a coin
what tests are used for the motor skills experiment
pretraining and post training tests
What is the plotting of the test informtaion called
performance curve or learning curve
learning/performance is greatly enhanced by
feedback/knowledge of results
knowledge of results test describe
blindfolded and must move the slider 10 cm to the right
how many trails in the knowledge of results test with no info
10
how many trials where they are told if too long short or correct
10
when is the subject correct
slider in within 0.5 cm of 10.cm
last 10 trails?
subject is told the excact distance they are from 10.cm
last step
repeat 10 trails with no info
what do we do with the results
graph a magnitude of error vs number of trails
describe transfer of learning
a habit already exstablished has an influence on the relearning or performance of a second habit
transfer of learning can be
positive or negative or both
what is bilateral transfer of skill
transfer can occur if skill is learned in one hand then attempted in the other
- aka a transfer of skill from one side of the body to another (cross-transfer or bilateral trans)
Mirror star trace apparatus
- trail 1 use non perfered hand to try draw star clock wise in the mirror
- always in contact with plate
1-trial
what other details of star procedure
must be done fast and we record errors
total score = error x2
what happens on the next step with the next hand
use preferred hand and do 10 trails
what happens at trail 12
do the non dominant hand again
