Abstract: In a dual-task paradigm, two tasks are performed concomitantly, and their performance is assessed relative to the performance of each task individually. The decline in performance that occurs during dual performance has been attributed to the limits on a construct referred to as attention (Wickens, 1980). Nideffer (1976) described attention as "the ability to direct our senses and thought processes to particular objects, thoughts, and feelings" (p. 340). Three major groups of theories attempt to explain the mechanism behind this decline in performance. The structural theories suggest that a fixed limit to attentional capacity results in a "bottleneck" in human information processing (e.g., Broadbent, 1958; Keele, 1973; Kerr, 1973; Welford, 1952). The capacity theories suggest that the available attentional capacity (or pool) can be allocated in a graded quantity between separate tasks until the limit on this capacity has been reached (e.g., Kahneman, 1973; Knowles, 1963). The multiple resource theories suggest there are several "pools" of attentional resources, each of which has its own capacity and is designed for certain types of information processing (e.g., Allport, Antonis, & Reynolds, 1972; Navon & Gopher, 1979; Wickens, 1980).
