In this project, we aim to further the understanding of processes involved in executive functions, essential for complex cognition and behavior. We are presently exploring the Dual Mechanisms of Control model, which distinguishes between proactive and reactive control processes. Proactive control involves sustained activation of task goals or context to enable the avoidance of conflicting information. Reactive control involves the more immediate resolution of conflicting information when it presents itself, with little advanced warning. We are investigating the relative age-related differences in these types of control within a variety of contexts such as classic cognitive tasks (switching, inhibition), fine motor (fingering) and gross motor (postural control) tasks.
