| Abstract: | The dual mechanisms of control (DMC) framework makes a distinction between proactive and reactive cognitive control processes. The results of a recent study suggest that the latter may be accompanied by a wider distribution of theta activity in the human brain than the former. The present study aimed to put that possibility to the test. The Add-n task, a digit transformation task, was used in an attempt to elicit proactive and reactive cognitive control processes in 37 individuals whilst their brain activity was being recorded by means of electroencephalography (EEG). Theta activity was found to be most pronounced at electrode FCz in all task conditions. Partial support was found for the notion that relatively challenging tasks and task conditions induce higher levels of frontal-midline theta activity than relatively unchallenging ones. Unlike expected, the results did not corroborate the idea that reactive cognitive control processes are accompanied by a wider distribution of theta activity in the human brain than proactive cognitive control processes. The attempted manipulation of the participants’ cognitive control strategies may not have been effective, however, so no definitive conclusions can be drawn. |
