Abstract

We investigated the simultaneous influence of expectation and experience on metacontrol, which we define as the instantiation of context-specific control states. These states could entail heightened control states in preparation for frequent task switching or lowered control states for task repetition. Specifically, we examined whether “expectations” regarding future control demands prompt proactive metacontrol, while “experiences” with items associated with specific control demands facilitate reactive metacontrol. In Experiment 1, we utilized EEG with a high temporal resolution to differentiate between brain activities associated with proactive and reactive metacontrol. We successfully observed cue-locked and image-locked ERP patterns associated with proactive and reactive metacontrol, respectively, supporting concurrent instantiation of two metacontrol modes. In Experiment 2, we focused on individual differences to investigate the modulatory role of working memory capacity (WMC) in the concurrent instantiation of two metacontrol modes. Our findings revealed that individuals with higher WMC exhibited enhanced proactive metacontrol, indicated by smaller response time variability (RTV). Additionally, individuals with higher WMC showed a lower tendency to rely on reactive metacontrol, indicated by a smaller item-specific switch probability (ISSP) effect. In conclusion, our results suggest that proactive and reactive metacontrol can coexist, but their interplay is influenced by individuals’ WMC. Higher WMC promotes the use of proactive metacontrol while attenuating reliance on reactive metacontrol. This study provides insights into the interplay between proactive and reactive metacontrol and highlights the impact of WMC on their concurrent instantiation.

The datasets are shared on Open Science Framework https://osf.io/q3ayh/?view_only=a26d8bb0b80c42ec8686e4e2687e7c0e.

Notes

  1. The criteria for excluding participants matched those of Experiment 2 but deviated from our preregistration protocol.

  2. We applied a less strict high-pass filter than what was preregistered (0.1 Hz instead of 0.5 Hz) after learning that high-pass filters can cause significant amplitude reduction in slow components when the cutoff exceeds approximately 0.1 Hz (Kappenman & Luck 2010).

  3. While we preregistered to investigate ERP differences between item types for assessing reactive metacontrol, we subsequently recognized that a more appropriate approach would be to analyze and report the cost of switching between item types (similar to what has been done for RT/accuracy).

  4. We adopted more flexible exclusion criteria relying on the mean and standard deviation of the current datasets, rather than using absolute cutoff criteria as stated in the preregistration. Additionally, two experiments were preregistered, but Experiment 2 described in the preregistration was not conducted.

  5. This deviated from the preregistration protocol, which originally intended to incorporate WMC as a categorical variable.

  6. The use of RTV was not preregistered.

  7. We furthermore reported the correlation between individuals' RTV and their mean RT as well as cost of switching. RTV showed a moderate correlation with cost of switching (Pearson’s r = .15, t(181) = 2.10, p = 0.037, after excluding 4 outliers) but not with mean RT (Pearson’s r = −.06, t(171) = −0.74, p = .461), after excluding 14 outliers.
