Steve Chang is an Assistant Professor of Psychology and Neurobiology. He has been at the forefront of using live social interaction paradigms in rhesus macaques for investigating the neural mechanisms of social decision-making and also examining how social motivation could be improved by neuromodulators both at the behavioral as well as at the level of single neurons. He hypothesizes that our social behaviors are heavily reinforcement-driven. He received Ph.D. from Washington University Neuroscience Program, and completed his postdoctoral work at Duke University. Steve teaches neuroscience-related courses from the Department of Psychology. Steve is happy to chat with anyone interested in psychology and neuroscience. You can reach him at steve.chang@yale.edu.
