Abstract

We examined the effect of a central tracking task on visual target processing efficiency in a combined target detection/manual tracking paradigm. Participants performed a redundant-target task by itself, and concurrently with the tracking task. A measure of workload capacity gauged target processing efficiency. Processing was less efficient than predicted by a standard parallel race model under both levels of task load. However, data suggested no difference in processing efficiency between the single- and dual-task conditions. Our findings provide further evidence that processing capacity for peripheral visual targets is consistently limited but robust against changes to concurrent task load.
