Infant and Toddler Oral and Manual Motor Skills Predict Later Speech Fluency in Autism

Journal of Child Psychology and Psychiatry, Gernsbacher, Sauer et al


Infant and toddler oral-motor and manual-motor skills inter-correlated significantly, distinguished autistic children from typically developing children, and distinguished autistic children whose current-day speech was minimally fluent, moderately fluent, and highly fluent. These results were corroborated by analysis of historical home video and verified with current-day assessment.
