The development of the coordination of the upper lip and lower lip was investigated in children ages four, seven, and ten. Strain gauge transduction techniques were employed to monitor lip movement during the production of selected disyllables. Significant changes in lip coordination were observed between the ages of seven and ten. Results are discussed in light of current understanding of neuromuscular maturation.
