Finding: Using hierarchical modeling to account for measurement error, researchers found that proactive and reactive cognitive control are only weakly correlated, supporting the Dual Mechanisms of Control framework's prediction of semi-independent control systems.
Why it matters: This demonstrates methodological approaches for measuring individual differences in cognitive control mechanisms that influence decision-making and goal-directed behavior.
Method: Applied hierarchical modeling to a large Stroop task dataset to simultaneously estimate measurement error and individual covariation, providing disattenuated correlation estimates with proper uncertainty quantification.
Jargon: Proactive control = anticipatory cognitive control engaged before stimulus onset; Reactive control = cognitive control triggered by stimulus/response features; DMC = Dual Mechanisms of Control framework.
