Rather than being persistently driven by cues and stimuli in the external world, people are capable of guiding their thoughts and actions independently, according to their internally-held goals. This ability, which has been called executive control, is so central to the human condition that we sometimes take for granted the capability to act according to our goals under any circumstances. Of course, we know that this is untrue in general, and that it is more untrue for some people than for others.

Executive control is an essential aspect of human behavior, yet it is quite fragile. Beyond obvious clinical disorders such as attention-deficit/hyperactivity disorder (ADHD), intrinsic limitations in executive control likely give rise to aspects of individual differences and situational influences on behavioral performance. My research has utilized an approach combining experimental manipulations and functional magnetic resonance imaging (fMRI) to isolate the neural mechanisms underlying critical executive functions, and to relate those functions to variation within and between individuals.

These executive control mechanisms may be important sources of variance in:
