The limited nature of mans attentional processes is a fundamental principle that underlies any general theory of human performance or human information processing. However, psychologists have been unable to settle upon a precise definition of the term attention. One approach that can be taken toward clarifying ambiguity in the meaning of attention is to study mans behavior in a time sharing paradigm, one in which attention must be shared between the performance of two or more tasks. The purpose of the current research was to examine these time-sharing effects in a manual tracking paradigm, employing the fine-grained analysis provided by the techniques of feedback control theory.
