Abstract
Webster (1988) described a means of using scattergrams to represent th e manual and nonmanual data from dual-task laterality experiments in a composite analysis. We used Webster's method and the conventional app roach (i.e., separate analyses) to analyze the results of an experimen t in which 40 right-handed adults performed a verbal and a manual task concurrently. Whereas separate analyses yielded dissimilar outcomes f or the two tasks, the scattergram analysis showed that overall interfe rence was greater when the right hand performed the manual task than w hen the left hand performed the manual task. Advantages of the scatter gram method for analyzing dual-task data are discussed.
