{"pk":25842,"title":"Linking Joint Attention with Hand-Eye Coordination – A Sensorimotor Approach to\nUnderstanding Child-Parent Social Interaction","subtitle":null,"abstract":"An understanding of human collaboration requires a level of\nanalysis that concentrates on sensorimotor behaviors in which the\nbehaviors of social partners continually adjust to and influence\neach other. A suite of individual differences in partners’ ability to\nboth read the social cues of others and to send effective behavioral\ncues to others create dyad differences in joint attention and joint\naction. The present paper shows that infant and dyad differences\nin hand-eye coordination predict dyad differences in joint\nattention. In the study reported here, 51 toddlers and their parents\nwore head-mounted eye-trackers as they played together with\nobjects. This method allowed us to track the gaze direction of\neach participant to determine when they attended to the same\nobject. We found that physically active toddlers align their\nlooking behavior with their parent, and achieve a high proportion\nof time spent jointly attending to the same object in toy play.\nHowever, joint attention bouts in toy play don’t depend on gaze\nfollowing but rather on the coordination of gaze with hand actions\non objects. Both infants and parents attend to their partner’s\nobject manipulations and in so doing fixate the object visually\nattended by their partner. Thus, the present results provide\nevidence for another pathway to joint attention – hand following\ninstead of gaze following. Moreover, dyad differences in joint\nattention are associated with dyad differences in hand following,\nand specifically parents’ and infants’ manual activities on objects\nand the within- and between-partner coordination of hands and\neyes during parent-infant interactions. In particular, infants’\nmanual actions on objects play a critical role in organizing parentinfant\njoint attention to an object.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Joint Attention"},{"word":"eye tracking"},{"word":"perception and action"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/4bg2k1x1","frozenauthors":[{"first_name":"Chen","middle_name":"","last_name":"Yu","name_suffix":"","institution":"Indiana University","department":""},{"first_name":"Linda","middle_name":"B","last_name":"Smith","name_suffix":"","institution":"Indiana University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2015-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/25842/galley/15466/download/"}]}
