In daily life, humans frequently perform visuospatial tasks together (e.g., visual search) and distribute the labour in such tasks. Previous research has shown that humans prefer a left and right labour division in a joint multiple object tracking (MOT) task. Yet, findings from studies investigating individuals' tracking ability suggest attentional capacities may be more maximally used with a top and bottom labour division. We investigated whether co-actors' labour division preference is

We find that pairs attain a higher performance using a top and bottom labour division and preferred this labour division compared to a left and right division. This preference was unaffected by the seating arrangement. For the landscape display, however, we find that participants no longer attain a higher performance for the top and bottom labour division and accordingly participants' preference for this labour division was greatly reduced as well. Overall, we propose that co-actors are sensitive to changes within their environment which allows them to choose a labour division that maximizes use of their individual attentional capacities.
