Abstract
Two dual-task experiments were designed to assess interference patterns between concurrent serial temporal production and memory updating tasks. Experiment 1 involved updating the value of a 3-digit sequence and Experiment 2 involved updating the value of a letter in the alphabet. Both experiments revealed a strong bidirectional interference effect between the timing and updating tasks. Compared with single-task conditions, dual-task conditions were associated with (a) longer and more variable temporal productions, and (b) less accurate memory updating judgments. In addition, greater numbers of updating operations led to progressively longer and/or more variable timing responses and progressively inaccurate updating responses. The results suggest that timing and updating depend on a common set of executive attentional resources.
