Our laboratory studies how humans exert control
over their thoughts and behavior, and how this control can break down. Cognitive
control is a central aspect of many higher-level functions, such as attention
and working memory. Further, the loss of cognitive control is a major component
of many neuropsychiatric diseases, such as schizophrenia. The ultimate goal
of our research is to contribute to an understanding of how cognitive control
emerges in the brain, in terms of the interactions between neural processing
elements, and without recourse to "homunculus"-type explanations.
Further, we wish to understand the role that loss of cognitive control plays
in neuropsychiatric disorders, and what underlying pathophysiology gives
rise to such control deficits. To achieve these goals, we use computational
modeling and convergent cognitive neuroscience methods. Descriptions of our current and recent research is listed below.
