The Measurement Of Motor Performance (Perceptual Motor Learning And Control Chapter 2)

Front 1

Performance Outcome Measures

Back 1

Motor skill performance measure that Measures outcome of performing a motor skill (how far, fast)

Front 2

Performance Production Measures

Back 2

"" Measures performance of specific aspect of motor system during performance of an action, technique (kinematics, force, EEG, EMG)

Front 3

Chronometry

Back 3

Timing and duration of cognitive operations in planning (RT, preMT, MT, etc)

Front 4

Reaction Time

Back 4

Interval between signal and initiation of response (beginning of movement)

Front 5

Movement Time

Back 5

Interval between initiation of movement and completion of movement

Front 6

Pre-Motor Time

Back 6

Interval between signal and EMG activity in performer (reception, interpretation sensory signal, plan, convey)

Front 7

Motor Time

Back 7

Interval between 1st change in EMG until movement begins.

Front 8

Response Time

Back 8

Reaction time and Movement Time together.

Front 9

Reaction Time Measures

Back 9

1. Simple (1 stimulus, 1 response) 2. Discrimination (multiple stimuli, 1 requires response) 3. Choice (multiple stimuli, each w/ difference response

Front 10

Response Outcome Measures

Back 10

1. Absolute Error 2. Constant Error 3. Variable Error 4. Total Error

Front 11

Absolute Error

Back 11

Absolute difference between performance on each trial and the goal (general idea of accuracy)

Front 12

Constant Error

Back 12

Takes directional bias into account (signed deviation), less accurate when applied to groups

Front 13

Variable error

Back 13

Represents consistency through standard deviation.

Front 14

Total Error

Back 14

Used to measure error in continuous skills to find how far participant was from the goal over time. (RMSE error)

Front 15

Performance Production Measures: Physiological Measures

Back 15

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)

Front 16

Kinematic Measures

Back 16

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

Front 17

Kinetic Measures

Back 17

PET, fMRI, TMS
