Abstract
Although goal pursuit is related to both functioning of the brain's reward circuits and psychological factors, the literatures surrounding these concepts have often been separate. Here, we use the psychological construct of regulatory focus to investigate individual differences in neural response to reward. Regulatory focus theory proposes two motivational orientations for personal goal pursuit: (1) promotion, associated with sensitivity to potential gain, and (2) prevention, associated with sensitivity to potential loss. The monetary incentive delay task was used to manipulate reward circuit function, along with instructional framing corresponding to promotion and prevention in a within-subject design. We observed that the more promotion oriented an individual was, the lower their ventral striatum response to gain cues. Follow-up analyses revealed that greater promotion orientation was associated with decreased ventral striatum response even to no-value cues, suggesting that promotion orientation may be associated with relatively hypoactive reward system function. The findings are also likely to represent an interaction between the cognitive and motivational characteristics of the promotion system with the task demands. Prevention orientation did not correlate with ventral striatum response to gain cues, supporting the discriminant validity of regulatory focus theory. The results highlight a dynamic association between individual differences in self-regulation and reward system function.

Rachel Alison Adcock
Dr. Adcock received her undergraduate degree in psychology from Emory University and her MD and PhD in Neurobiology from Yale University. She completed her psychiatry residency training at Langley Porter Psychiatric Institute at UC-San Francisco and did neurosciences research as a postdoctoral fellow at UC-SF, the San Francisco VA Medical Center, and Stanford before joining the Duke faculty in 2007. Her work has been funded by NIDA, NIMH, NSF and Alfred P. Sloan and Klingenstein Fellowships in the Neurosciences, and the Brain & Behavior Research Foundation, and honored by NARSAD awards, the 2012 National Academy of Sciences Seymour Benzer Lectureship, and the 2015 ABAI BF Skinner Lectureship. The overall goals of her research program are to understand how brain systems for motivation support learning and to use mechanistic understanding of how behavior changes biology to meet the challenge of developing new therapies appropriate for early interventions for mental illness.

Timothy J. Strauman
Professor Strauman's research focuses on the psychological and neurobiological processes that enable self-regulation, conceptualized in terms of a cognitive/motivational perspective, as well as the relation between self-regulation and affect. Particular areas of emphasis include: (1) conceptualizing self-regulation in terms of brain/behavior motivational systems; (2) the role of self-regulatory cognitive processes in vulnerability to depression and other disorders; (3) the impact of treatments for depression, such as psychotherapy and medication, on self-regulatory function and dysfunction in depression; (4) how normative and non-normative socialization patterns influence the development of self-regulatory systems; (5) the contributory roles of self-regulation, affect, and psychopathology in determining immunologically-mediated susceptibility to illness; (6) development of novel multi-component treatments for depression targeting self-regulatory dysfunction; (7) utilization of brain imaging techniques to test hypotheses concerning self-regulation, including the nature and function of hypothetical regulatory systems and characterizing the breakdowns in self-regulation that lead to and accompany depression.
