Dual Task Performance

Even dissimilar tasks interfere with one another when done together. We used visual search to examine the underlying cause of such interference. In many models, visual search is a process of biased competition controlled by a template describing the target to be sought. When the display is processed, matching against this template guides attention to the target. We show that increasing template complexity increased interference with a dissimilar concurrent task, story memory. This result was independent of reaction time: Increases in template complexity were associated with no increase in search time in Experiment 1 and with a decrease in search time in Experiment 2. The results show that the dual-task demands of visual search reflect the complexity of the template used in task control, and that this factor can be isolated from other sources of difficulty.

Dual Task Performance

This study aimed to examine how workload and automation aid type affected operators’ trust in automation, attention allocation and dual-task performance. With a simulated surveillance task, participants monitored the picture steaming from an unmanned ground vehicle (UGV) while planning the paths of two unmanned aerial vehicles (UAVs). The analysis of experimental results indicated that workload affected operators’ attention allocation and dual-task performance, but not their trust in automation. As workload increased, attention allocation on the automated task decreased and on the concurrent task increased. Moreover, an increasing workload led to longer response time for the automated task. For the concurrent task, higher workload harmed task performance accuracy but resulting in shorter response time.
