Developmental Milestones: Sign Language Acquisition and Motor Development.

Bonvillian, John D.; And Others

Child Development, v54 n6 p1435-45 Dec 1983

Studied across a 16-month period, young children of deaf parents showed accelerated early language development, on the average producing their first recognizable sign at 8.5 months, their tenth sign at 13.2 months, and their first sign combination at 17.0 months. Findings are inconsistent with previously reported patterns of synchrony between motor and language development. (Author/RH)
