The average proportion of verbs that late talkers knew. The group average proportion of verbs known (.108) is indicated by a horizontal line; proportions range from 0.073 (ditransitive verbs) to 0.117 (result verbs). Given that late talkers know fewer verbs than typically developing children, the y-axis differs from that in Figure 1. Error bars indicate standard errors of child means.
