I use a combination of studies of human behavior, eye tracking, human functional magnetic resonance imaging (fMRI), and electroencephalography (EEG) to investigate the behavioral consequences and neural mechanisms associated with attentional and cognitive control.
- Do individuals harness previous learning to adapt the flexibility of goal-directed attention? A critical component of human cognition is the ability to flexibly shift the focus of attention, switch tasks (e.g. multitasking), and update the contents of working memory. Does an individual’s readiness to shift, known as cognitive flexibility, vary according to their previous experiences? To what degree does this flexibility extend across areas of cognitive control (e.g. visual attention, task-switching, and working memory updating)? What are the neural mechanisms involved in the acquisition and implementation of cognitive flexibility?

- How does learning influence the involuntary deployment of attention? Do reward-associated items distract us more than non-rewarding items? Do our previous experiences influence where attention is deployed from moment to moment, even when these experiences conflict with our goals? In recent studies, I have tested whether reward-based attentional priority relies on reinforcement learning and have explored differences in reward-based attentional capture among children with ADHD and their typically-developing peers.
