Legend:
Mean vowel durations (top three panels) and transition durations (bottom three panels) for the three subject groups for the three CV types. Error bars indicate plus one standard deviation. Open bars show individual means for fast-rate productions; cross-hatched bars show individual means for normal-rate productions. Dotted lines show group means for fast-rate productions; solid lines show group means for normal-rate productions. Children with phonological disorders (rank-ordered by age) are shown in the left third of each panel, age-matched controls are shown in the middle third of each panel, and adults are shown in the right third of each panel. No data are shown at the normal rate for the oldest child with a phonological disorder because he produced no noise-free productions at this rate.
