Hypothesized top-down and bottom-up mechanisms of control within conflict-rich
environments were examined by presenting participants with a Stroop task in which specific …

Neural mechanisms of cognitive control are hypothesized to support flexible, goal-directed
behavior by representing task-relevant information in order to guide thought and action. The …

Given the information overload often imparted to human cognitive-processing systems,
suppression of irrelevant and distracting information is essential for successful behavior …

Two experiments examined the relations among working memory capacity (WMC),
congruency-sequence effects, proportion-congruency effects, and the color-word Stroop …

Introduction: Attention-deficit hyperactivity disorder (ADHD) is one of the most frequent
neurodevelopmental disorders in children and tends to persist into adulthood. Evidence …

The idea that adaptation to stimulus or response conflict can operate over different time
scales takes a prominent position in various theories and models of cognitive control. The …

Current models of cognitive control assume gradual adjustment of processing selectivity to
the strength of conflict evoked by distractor stimuli. Using a flanker task, we varied conflict …

There has been accumulating evidence that cognitive control can be adaptively regulated by
monitoring for processing conflict as an index of online control demands. However, it is not …

In this study, we leveraged the high temporal resolution of EEG to examine the neural
mechanisms underlying the flexible regulation of cognitive control that unfolds over different …

Sequential modulation of congruency effects in conflict tasks indicates that cognitive control
quickly adapts to changing task demands. We investigated in four experiments how this …
