This $550,000 project grant awarded by the National Science Foundation (NSF) Social, Behavioral, and Economic Sciences (SBE) program (CFDA 47.075) aims to develop a psychological and neural model of conflict resolution. The research will combine behavioral methods, computational modeling, neuroimaging, and non-invasive brain stimulation to interrogate the time course and neural mechanisms underlying how individuals resolve conflicts between automatic impulses and goal-directed behavior. The project has four key research aims: 1) validating the response preparation model using physiological data, 2) comparing the model against prior sequential sampling models, 3) assessing the causal role of lateral prefrontal cortex in conflict resolution using fMRI and TMS, and 4) evaluating the generality of the conflict resolution mechanism across tasks. The project also plans to involve undergraduate students, including those from underrepresented groups, in the research. The award reflects NSF's mission to advance fundamental scientific understanding and have broader societal impacts. No subawards are planned under this grant, which has an ultimate completion date of May 31, 2027.
