Applications are invited for a postdoctoral fellowship working on a collaborative project with Dr. Joe Kable (in the Department of Psychology) and Dr. Ted Brodkin (in the Department of Psychiatry) at the University of Pennsylvania. The project seeks to examine the neural and genetic bases of individual differences in social preferences, and particularly those leading to excessive selfishness, using parallel assays across humans and mice. The postdoctoral fellow will most likely focus on behavioral and neuroimaging studies in humans, and therefore previous experience with fMRI and/or decision-making research is preferable but not necessary. Applicants interested in work bridging across species would also be welcome. The ideal candidate will have a Ph.D. in neuroscience, psychology or related field, strong computational skills, and a strong record of previous research. Penn offers an outstanding research environment, and this position provides an exciting opportunity to work in a collaborative team science environment. The initial appointment would be for two years. Start date is flexible. Inquiries or applications should be directed to Joe Kable (firstname.lastname@example.org). Applicants should include a cover letter describing their research interests and career plans, CV, and contact information for three references.
Research in the Kable Lab seeks to understand how people make decisions, and to trace out the psychological and neural mechanisms of choice. We employ an interdisciplinary approach to tackle these questions, drawing on methods and ideas from social and cognitive neuroscience, experimental economics, and personality psychology. We aim to draw links across these different levels of analysis, and to build explanations of decision-making that account for both people's choices and the neural mechanisms underlying those choices.
One of our goals is to understand the mechanisms underlying changes in people's preferences. Recently, we have used fMRI to show that the subjective value people place on different rewards is represented in a common neural currency -- a "utility"-like neural signal. We are now examining how neural value signals change when people change their decisions for different reasons (e.g., heuristics and biases, preferences evolving over time, education, or social influence).
Another goal is to understand the different sources of individual differences in decision making. Recently, we have reported dramatic differences across individuals in impulsivity, which are associated with how certain brain regions are active during decision-making. We aim to explore the extent to which differences in decision-making are stable and trait-like as opposed to context-dependent, and to analyze the psychological, genetic, and neural sources of these differences.
