Peer interactions in 4/6-month-old infants: From motor development to
Our goal was to explore the potential continuity between motor activity
observed in early social situations and communication development.
Thirteen infants between 4 and 6 months of age were observed in daycare
centers, either on their own or in dyads, and in two postural
conditions: lying on a playmat or seated in bouncers. Infants were found
to modify their posture, movements and gaze behavior in dyadic
situations compared to situations alone. Moreover, the bouncers
facilitated visual interactions while the playmat favored the production
of hand movements. This work highlights the need to analyze multimodal
characteristics of interactions and to add posture variations as a key
variable to better understand how infants develop communicative
intention toward their peers.
