Teaching gestural signs to infants to advance child development: A review of the evidence
University of Ottawa
University of Waterloo Should parents be encouraged to teach their hearing infants to communicate using gestural signs? Does signing in infancy advance child behaviour and development as claimed by many commercially available products for parents? To answer these questions, a review was undertaken to evaluate currently available research studies that examined the effectiveness of prelingual signing for normally developing, hearing infants. Databases, reference lists and the Internet were searched for relevant documents using a pre-determined search protocol. Seventeen reports met the reviews inclusion criteria and were retrieved and evaluated. The review failed to support claims that signing facilitates language development, due to insufficiencies in scientific methods and to equivocal results.
