A study published in the Journal of Child Psychology and Psychiatry evaluated the effectiveness of a parent-led early language program compared to a motor skills program in preschool age children. The primary goal was to assess whether the oral language program would prompt advances in early language and reading skills relative to children who were in the motor skills program. Children were randomly assigned to either the oral language or motor skills programs. The two programs were delivered by parents at the same intensity: 20-minute sessions, 5 days each week for 30 weeks.
