Abstract
Two separate experiment using motor responses evaluated the specificity vs. generality of response consistency when the various tasks used the same limb for response. In Exp. I four similar tasks requiring rapid right arm movement were defined and, in Exp. II, Ss had to "hit" a moving target with either a maximal or moderately fast right hand movement. Although the mean intercorrelations among tasks were generally moderate to low (mean r = .85 and .30, respectively for Exp. I and II) the intercorrelations using response consistency scores (the SD of S's responses about his own mean) were lower for Exp. I (mean r = .54) and similar for Exp. II (mean r = .30). These findings provided little support for a notion of a general within-limb factor of motor response consistency.
