Abstract : In the study examined, subjects (Ss) were required to perform a continuous two-dimensional tracking task whose criteria included RMS Error in both dimensions as well as the number of times the Ss manipulated the control stick in either dimension. Occasionally, one of two other discrete tasks (i.e., a tactical assessment task and a communications task) occurred. Performance on the discrete tasks included accuracy of responses as well as response time for both correct and incorrect responses. Over a period of time, this provided potential data about percent of correct, incorrect, and missed responses as well as median times for both correct and incorrect responses. Thus, several criteria were available for each of the three tasks. The tracking data analyzed in this study were limited to only those data which occurred during and immediately after the occurrence of either type of discrete task. This approach was taken because, in the absence of a second actual task, the tracking task was the only one which Ss had to actively perform, although Ss were responsible for monitoring if a new target had appeared which required their assessment.
