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

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
