dual-task competition

a phenomenon observed in experimental techniques examining dual-task performance, in which participants are asked to perform two tasks (e.g., speeded reaction time and mental arithmetic) simultaneously. Such tasks require effort (see effortfulness) and tend to compete against each other (see resource competition), resulting in increased error rates and longer reaction time. The decrease in performance is often taken as an index of conscious, voluntary, and attentional capacity limits (see central limited capacity).
