{"pk":26296,"title":"Measuring the Causal Dynamics of Facial Interactionwith Convergent Cross Mapping","subtitle":null,"abstract":"The nature of the dynamics of nonverbal interactions is of con-siderable interest to the study of human communication andfuture human-computer interaction. Facial expressions consti-tute an important source of nonverbal social signals. Whereasmost studies have focused on the facial expressions of iso-lated individuals, the aim of this study is to explore the cou-pling dynamics of facial expressions in social dyadic interac-tions. Using a special experimental set-up, the frontal facialdynamics of pairs of socially interacting persons were mea-sured and analyzed simultaneously. We introduce the use ofconvergent cross mapping, a method originating from dynam-ical systems theory, to assess the causal coupling of the dyadicfacial-expression dynamics. The results reveal the presence ofbidirectional causal couplings of the facial dynamics. We con-clude that convergent cross mapping yields encouraging resultsin establishing evidence for causal behavioral interactions.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"mimicry; convergent cross mapping; facial ex-pressions"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/08p997t9","frozenauthors":[{"first_name":"Eric","middle_name":"","last_name":"Postma","name_suffix":"","institution":"Tilburg University","department":""},{"first_name":"Marie","middle_name":"","last_name":"Postma-Nilsenova","name_suffix":"","institution":"Tilburg University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2016-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26296/galley/15932/download/"}]}
