|
Indicates the outcome or results of performing a motor skill.
e.g. how far, how fast, how many degrees of elbow flexion, kinematics, etc... |
performance outcome measures
|
|
|
Indicates the performance of specific aspects of the motor control system; how the nervous/muscular systems are operating or the limb/joint movement.
e.g. force, eeg, emg, kinetics, etc... |
performance production measures
|
|
|
Interval of time between the onset of a stimulus and the initiation of a response; does not include the movement related to the action.
Bell, buzzer, gun...usually a lag time. |
Reaction time
|
|
|
one signal, one response
|
simple reaction time
|
|
|
More than one signal, each signal has a specific response.
|
choice reaction time
|
|
|
More than one signal, only one response.
|
discrimination reaction time
|
|
|
Time between stimulus and onset of muscle activity, indicates perceptual/cognitive decision making capacity.
|
premotor time
|
|
|
time from increased muscle activity to the beginning of observable movement.
|
motor time
|
|
|
Interval of time between the initiation of movement and the completion of movement.
Movement time begins when response time ends. |
movement time
|
|
|
reaction time+movement time=
|
response time

|
human performance
|
|
|
training of reaction time or movement time does not aid in the ________ of the other.
|
improvement
|
|
|
Allow for the evaluation of performance accuracy.
Indicates the possible causes of performance problems. |
error measures
|
|
|
Lack in acquiring the basic movement pattern needed to perform the skill.
|
problems associated with consistency
|
|
|
Person had acquired the movement pattern, but having difficulty adapting to the specific demands of the situation.
|
bias problems
|
|
|
Absolute difference between the actual performance and the goal.
All the scattered patterns. |
absolute error (AE)
error measure to asses accuracy. |
|
|
Index of a person's tendency to be directionally biased.
+ or -, overshoot or undershoot goal. Specific bias. |
constant error (CE)
error measure to assess accuracy. |
|
|
Indicates performance consistency.
Calculate standard deviations of the CE scores for the series of trials. |
variable error (VE)
error measure to assess accuracy. |
|
