In this article, the authors discuss and examine how to develop time sharing using a dual motor task and its effects. They state that when one is required to perform two tasks at the same time (time sharing), an individual may experience difficulty in expressing one or both of the tasks. This phenomenon, known as interference, has been studied using a dual task paradigm (Abernathy,1988). In 1991, Whithall used a dynamic pattern perspective to interpret time sharing in a dual task paradigm, when she examined the effect of a concurrent verbal cognition on locomotor skills. She predicted that the emergence of a particular behavior pattern of the coordination variables, a self-organizing process, would not require attentional mediation and would be unaffected by concurrent cognitive task. On the other hand, the internally regulated task demands of speed or force were more actively controlled by the performer and, therefore, would be affected in the dual task condition.
