Peter received his Ph.D. in Psychology from New York University in Elizabeth Phelps' lab. He did postdoctoral training with Antonio Rangel at Caltech, and then with Nathaniel Daw and Elizabeth Phelps at NYU. In his work, he enjoys integrating the perspectives and methods associated with different fields, including cognitive psychology, cognitive neuroscience, and microeconomics, to understand how we assess value, how we use value to guide behavior, and the ways that emotion is integrated into those processes.
Chelsey is the Lab Manager and Research Assistant, splitting their time between the Sokol-Hessner and AACT Labs. They graduated from Stanford University with a B.A. in Psychology working with Professors Hyowon Gweon and Jamil Zaki in the Social Learning Lab and Stanford Social Neuroscience Lab. They researched how people learn about and make decisions regarding other’s preferences, and how motivation to affiliate influences perceptions of shared preferences. They are generally interested in the ways we engage with the social world, how one’s perceptions are influenced by their social interactions, and the potential clinical applications of such research.
Hayley received her Master's degree in Psychology from New York University researching the relationship between sleep related problems and behavioral functioning, affective development, and cognitive processing in children with Autism Spectrum Disorder. Her research interests primarily involve the development of the brain mechanisms underlying self-regulation and decision-making across adolescence and into adulthood.
Hayley started as a full time as a graduate student in Fall 2017.
