Description

The Dual Mechanisms of Cognitive Control Project

The Dual Mechanisms of Cognitive Control (DMCC) project provides a rigorous experimental test of a theoretical framework positing two key modes of control ¬– proactive and reactive – that may reflect domain-general dimensions of individual variation. This framework is currently being evaluated through an on-going, larger-scale fMRI neuroimaging study (target N=200), as well as through an on-line behavioral study (multiple waves of testing, each with N > 100). Both feature a multi-session protocol, composed of a novel cognitive control task battery, plus comprehensive, individual differences assessment. I’ll provide an overview of the study design & protocol, current and planned analytic approaches, and methodological development, along with initial behavioral, psychometric, and neuroimaging findings. In the interest of encouraging shared engagement by the scientific community, DMCC data will be made fully public at study completion; a partial dataset has already been released.
