This project characterizes the development of early social interactions in a longitudinal sample of mothers and their infants. To do this we track the interaction in as a temporal configuration of multimodal, multiparty components, coding a total of 14 dimensions at each frame. Our final goal is to develop methods which we can use to systematically document regularities in the way attention gets organized longitudinally in a large sample of mother-infant dyads. Coding systematically at this scale allows us to ground a developmental account of early social interaction. For this project, we developed 1) ways to reduce the labor intensity of coding frame-by-frame multidimensional data over the entire sample and 2)ways of quantifying complex configural regularities across our sample. © ACM 2010.
