What is it about?
Tasks that induce intereference between different responses are commonly used to investigate cognitive control, i. e. the cognitive state controlling the weighting of task-relevant to task-irrelevant information. Previous research suggested that in these tasks cognitive control decays over course of 3-5 seconds. In this study, we show that cognitive control is temporally stable as long participants are incentivized by the task structure to rely on pure control strategies in contrast to relying on memory for stimulus-response combinations.

Why is it important?
Research on the maintenance of cognitive control is important to advance existing theories, since these usually incorporate temporal aspects of control adaptations on a very abstract level which is helpful for experimental work, but does not reflect the temporal uncertainties in real life situations.

Congruency Sequence Effects, the measure of cognitive control, in RTs (left panel) and error rates (right panel) separately for a task design incetivizing to use pure control strategies (blue) and a design that allows to use memory strategies (red) with the preceding time intervals on the x-axis. The dashed lines represent aggregated regression models with averaged intercepts and regression coefficients. Error bars indicate the 95% within confidence interval of the Congruency Sequence Effects.
