Research

Executive systems and their involvement in personality and mental illness; Event-related potentials

Research Synopsis

The brain’s information processing capacity is a limited resource. Allocating a limited-capacity resource is an economic problem. My research uses human event-related potentials to study how neural motivation systems, particularly the reward system, use economic principles, e.g. expected value, to optimize information processing. We also study how motivation system biases may be related to personality and how system dysfunction may be associated with mental illness.
