visual tracking & pointing movements
Multiple object tracking (MOT) and goal directed movements are based on attentional processes. Previous studies have shown that MOT influences aiming movements, although it was the result of loading working memory rather than attention. This study focused on the instant effect of attentive tracking on pointing performance. We measured the precision of the pointing movements that were performed to the targets of a MOT task just after the tracking period when all the objects were in motion. The results demonstrated that higher number of objects in MOT decreased pointing precision. We also manipulated the relation between number of targets and the density of MOT display which affected MOT accuracy and not the pointing precision.
