Performance Outcome Measures
|
Motor skill performance measure that Measures outcome of performing a motor skill (how far, fast)
|
|
Performance Production Measures
|
"" Measures performance of specific aspect of motor system during performance of an action, technique (kinematics, force, EEG, EMG)
|
|
Chronometry
|
Timing and duration of cognitive operations in planning (RT, preMT, MT, etc)
|
|
Reaction Time
|
Interval between signal and initiation of response (beginning of movement)
|
|
Movement Time
|
Interval between initiation of movement and completion of movement
|
|
Pre-Motor Time
|
Interval between signal and EMG activity in performer (reception, interpretation sensory signal, plan, convey)
|
|
Motor Time
|
Interval between 1st change in EMG until movement begins.
|
|
Response Time
|
Reaction time and Movement Time together.
|
|
Reaction Time Measures
|
1. Simple (1 stimulus, 1 response) 2. Discrimination (multiple stimuli, 1 requires response) 3. Choice (multiple stimuli, each w/ difference response
|
|
Response Outcome Measures
|
1. Absolute Error 2. Constant Error 3. Variable Error 4. Total Error
|
|
Absolute Error
|
Absolute difference between performance on each trial and the goal (general idea of accuracy)
|
|
Constant Error
|
Takes directional bias into account (signed deviation), less accurate when applied to groups
|
|
Variable error
|
Represents consistency through standard deviation.
|
|
Total Error
|
Used to measure error in continuous skills to find how far participant was from the goal over time. (RMSE error)
|
|
Performance Production Measures: Physiological Measures
|
1.Kinematic measures (quality of motion w/ respect to time, but not force 2. Kinetic Measures (describe forces that produce displacement in parts of body during movement)
|
|
Kinematic Measures
|
1. displacement (spatial position of part of body in movement) 2. velocity (direction/magnitude of movement) 3. acceleration (rate at which velocity changes) EMG measures muscle activity of agonist/antagonist during movement
|
|
Kinetic Measures
|
PET, fMRI, TMS
