Description: In previous work we did in our lab, we developed a modified trajectory tracking MOT task that did not require identity-location bindings to be formed because probed priorities were presented on entire screen parts (i.e. upper and lower) and not on individual targets. The results further supported findings of Crowe et al. (2019) as it has been found that even in a task that did not require this binding to be formed, better tracking performance was observed in high versus low priority areas of the screen, indicative of unequal attention allocation. These findings were further supported by eye tracking data collected, showing that gaze was allocated preferentially to high versus low priority screen areas, indicating a flexible nature of attentional resource. Exploratory analysis revealed a positive relationship between participants’ error and distance of their eye gaze from the centre, indicating that when participants fixated near the centre, tracking accuracy was improved. The current experiment is aimed at testing between alternative hypotheses concerning the causal link between gaze behaviour and tracking performance. In addition, having established that attention can be unequally divided between top and bottom visual fields, the current experiment aims to investigate whether attention can be unequally divided between left and right visual fields as well as.
