Movement ResponseMovement Response
Reaction time and movement time used together to determine whether movement is being planned in advance or during execution
Practical Implication?
Performance ErrorsPerformance Errors
Absolute Error - measures the overall amount of error in performance
X1 + X2| + |X3| + …/ # trials
(without regard to sign)
Performance ErrorsPerformance Errors
Variable Error - represents the degree of consistency or variability associated with a performance
(X1) + (X2) + (X3) + …/ # trials
consider sign
Performance ErrorsPerformance Errors
Constant error - measures level of bias in performance - considers amount and direction of error
CE - (CE) /# trials# trials
