Research Interests: basic motivational and cognitive
processes, the disruption of these processes in psychopathology,
and the role of these processes in effective interventions
Dr. Hawk is a clinical psychologist. His research takes a translational approach, examining the role of basic cognitive and motivational processes in psychopathology and its treatment. His current funded work focuses on cigarette smoking and on ADHD. Pre-Cessation Effects of Bupropion on Smoking (NCI) tests an extinction hypothesis for the efficacy of bupropion within the framework of small clinical trial. Inhibitory Control and Clinical Response in ADHD (NIMH) examines the degree to which changes in putative core processes in ADHD (e.g., inhibitory control, sustained attention, delay-related impulsivity) explain individual differences in clinical response to stimulant medication. Both studies seek to understand the basic cognitive, learning, and motivational processes that mediate the clinical efficacy of pharmacologic interventions. Dr. Hawk is a co-investigator on three additional on-going projects: Motivation in Context: Risk for Early Substance Use (NIDA), Problem Behavior, Peers, and Motivational Aspects of Temperament in Substance Use (NIDA), and Impulsivity and Emotion Dysregulation in Borderline Personality Disorder (NIMH). Dr. Hawk's work takes a biobehavioral perspective, incorporating psychophysiological, behavioral, and subjective methods.
