Abstract
Visual working memory (VWM) is a highly limited cognitive system. Thus, protecting task-relevant information against external interference is essential for the efficient use of this limited resource. Prior research suggests that regularities in temporal structure can enhance VWM function against interference via anticipatory mechanisms. In a set of two dual-task experiments, we investigated whether the temporal predictability of interference-task onset mitigates the detrimental impact of interference on colour VWM performance. Under conditions of increased cognitive load (Experiment 2), temporal predictability seemed to enhance general VWM performance—an effect absent under less cognitively demanding conditions (Experiment 1). Contrary to our hypothesis, however, temporal expectancy of interference onset did not aid VWM protection, across both experiments. Our findings suggest that VWM benefits of predictable temporal structures emerge only under conditions of increased cognitive load, but temporal predictability does not seem to be implicated in the protection of colour VWM representation against interference.
