Social Cognition and Social Responsiveness in 10-month-old Infants

In this study, we investigated relations between infants' understanding of intentional actions and measures of social responsiveness during a transitional period, 9- to 11-months. Infants (N = 52) were tested in visual habituation paradigms tapping their understanding of the relation between a person and the object of her attention. Measures of social responsiveness included orienting to the target of another's attention, point production, and supported joint attention in parent---child play. Infants' responses to the habituation events were related to their social responsiveness. Distinct factors for understanding actions and social responsiveness as relational were revealed. Infants who produced object-directed points were more likely to understand pointing as relational, and infants who engaged in high amounts of shared attention were more likely to understand gaze. Infants' tendency to orient in response to an adult's gaze shifts and points was unrelated to their understanding of gaze and pointing. These findings elucidate the ways in which social cognition and social responsiveness, although distinct, are related in development.
