Adaptive automation may help balance system autonomy with human interaction in supervisory control environments. Recent results have demonstrated a benefit of performance-based adaptive automation in a multiple unmanned aerial vehicle simulation. However, these findings may instead reflect an attentional benefit from having the task autonomy level change. A betweensubjects experimental design was employed to test this possibility. In one group task autonomy level changed with task performance; in the other group levels changed as a function of time elapsed. The results indicated that performance did not significantly differ between the two groups. However, there were significantly more autonomy level changes in the performance-based adaptive automation group. A follow-on study utilizing a yoked-subject design is recommended.
