title: The effect of practice on human performance in a preview-constrained motor control task.
abstract: This study examined the effect of short-term practice on the parameters of a linear model involving mean arm movement time as a function of Fitts's index of difficulty (ID) variable and a preview-constraint ID variable. Significant (at the 2% level) interactions were found to exist between practice and the two ID variables indicating that the model parameters associated with these variables are both linear functions of practice time.
