Talk Title: A network supporting social influences in human decision-making
Abstract: Most human decision-making takes place in a social context, which could influence individual decisions. Using a novel probabilistic reversal learning task in a social setup, we observed opposite effects of social influence on choice and confidence. People succumb to the group when confronted with dissenting information whereas increase their confidence when observing confirming information. Using computational modeling and functional neuroimaging of goal-directed learning, we were able to separate normative influence leading to changes in choice behavior and informational influence resulting in changes in value computations, and identified their unique neural representations. The subsequent valuation was accommodated by both reward prediction error and social prediction error. Moreover, we established an interaction of two brain networks related to processing reward and social information, which modulates behavioral adjustment.
MRI Users Workshops are monthly informal gatherings for users who are interested in getting to know each other and talking science. The workshop is open to all, and students and postdocs are particularly encouraged to attend.
Workshops typically include a short presentation of work (15-25 minutes) with an extended discussion at the end. The presentations will be live-streamed and recorded in collaboration with the OnNeuro platform, check it out here! Refreshments are provided!
Workshops take place on the third Friday of each month at 1:00pm, in the Psychology Building, Room 217. To receive meeting details and related MRI announcements, please complete a request form and specify that you would like to be added to the CCBBI mailing list.
