Two are better than one: Infant language learning from video improves in the presence of peers

Studies show that young children learn new phonemes and words from humans significantly better than from machines. However, it is not clear why learning from video is ineffective or what might be done to improve learning from a screen. The present study, conducted with 9-month-old infants, utilized a manipulation-touch screen video-which allowed infants to control presentations of foreign-language video clips. We tested the hypothesis that infant learning from a screen would be enhanced in the presence of a peer, as opposed to learning alone. Brain measures of phonetic learning and detailed analyses of interaction during learning confirm the hypothesis that social partners enhance learning, even from screens.
