Individual differences in multi-task response strategies.

This paper presents the results of two experiments examining individual differences in multiple-task performance. In the first experiment, the subjects were classified according to the response strategy they used to perform two discrete tasks. The subjects then performed three different task combinations on four successive days. A multivariate analysis of variance revealed significant between-strategy group differences in multiple-, but not single-, task performance. The second experiment was designed to determine if the results of the first experiment reflected between-group differences in information processing. The analyses indicated that one strategy group processed multiple-task information significantly more poorly than the other two groups.
