{"pk":28112,"title":"Neural Coupling Between Infants and Adults Supports Successful Communication","subtitle":null,"abstract":"Infancy is the foundational period for learning from adults, and the dynamics of the social environment have long beenproposed as central to childrens development. Here we reveal a novel, naturalistic approach for studying live interactionsbetween infants and adults. Using functional near-infrared spectroscopy (fNIRS), we simultaneously and continuouslymeasured the brains of infants (9-15 months) and an adult while they communicated and played with each other in realtime. We found that time-locked neural synchrony within dyads was significantly greater when they interacted witheach other than with control individuals. In addition, we found that both infant and adult brains continuously trackedthe moment-to-moment fluctuations of mutual gaze and infant emotion with high temporal precision. This investigationmarks a new means of understanding how the brains and behaviors of infants both shape and reflect those of their caregiversduring real-life communication.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0k6109w8","frozenauthors":[{"first_name":"Elise","middle_name":"","last_name":"Piazza","name_suffix":"","institution":"Princeton","department":""},{"first_name":"Liat","middle_name":"","last_name":"Hasenfratz","name_suffix":"","institution":"Princeton","department":""},{"first_name":"Uri","middle_name":"","last_name":"Hasson","name_suffix":"","institution":"Princeton","department":""},{"first_name":"Casey","middle_name":"","last_name":"Lew-Williams","name_suffix":"","institution":"Princeton","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/28112/galley/17772/download/"}]}
