Outcome measures - ANS what happened in terms of physical action, outcome of the
movement
outcome measurement - ANS magnitude
success rate
amount of error
secondary task performance
speed
accuracy
process characteristics - ANS how you achieve a movement
process measures - ANS fine vs large and uncontrolled movement
precision
variability in movement

,movement kinematics
muscle activity
brain activity
error scores - ANS give information about the accuracy, bias, and consistency of a
performance
constant error - ANS how far away from the target, and in which direction
tells us about bias
absolute error - ANS absolute value of the distance from the target
tells us about accuracy
Variable error - ANS consistency around your own average score
tells us about consistency
total error (RMSE) - ANS consistency around the target
tells us about consistency
Vision - ANS dominant source of sensory input for motor control
interaction and perception
McGurk effect - ANS things you see can influence what you hear
ex. Ba - Fa

, Two streams hypothesis - ANS visual information is processed in two separate streams, dorsal
and ventral
Dorsal stream - ANS vision for action
damage causes optic ataxia
Ventral stream - ANS vision for perception
damage causes visual agnosia
Optic ataxia - ANS inability to use vision to guide movements
Visual agnosia - ANS inability to recognize presented objects, but still able to interact with
them
Joint receptors - ANS give information about tension
when at end of ROM - protective mechanism
max flexion / extension
skin receptors - ANS heavy pressure
vibration
light touch
skin stretch
Muscle spindles - ANS changes in length of muscle fiber
