Effects of environmental stimulation on infant vocalizations and orofacial dynamics at the onset of canonical babbling
MP Harold, SM Barlow�- Infant Behavior and Development, 2013 - Elsevier
The vocalizations and jaw kinematics of 30 infants aged 6–8 months were recorded using a
Motion Analysis System and audiovisual technologies. This study represents the first attempt
to determine the effect of play environment on infants' rate of vocalization and jaw
movement. Four play conditions were compared: watching videos, social contingent
reinforcement and vocal modeling with an adult, playing alone with small toys, and playing
alone with large toys. The fewest vocalizations and spontaneous movement were observed�…
