We studied gesture and language production in 21 Mandarin-speaking late talkers at 24 months of age and compared them with 28 age-matched typically developing children to determine their gestural and cross-modal communicative abilities. Spontaneous cross-modal data were collected during naturalistic mother-child interactions. Results from the Words and Sentences survey of the MCDI-T showed that late talkers had underdeveloped vocabulary and grammatical complexity. Nonetheless, their gestural competence was intact and comparable to that of typically developing children. Both groups demonstrated similar patterns in using declarative pointing, imperative pointing, showing, giving, representational, and conventional gestures to achieve communicative goals. Among these, declarative pointing was the most common for establishing joint attention and sharing interests or information with the addressee. Although late talkers were capable of reinforcing, clarifying, and supplementing speech with gestures, they did so less frequently than their typically developing peers. In sum, late talkers used gestures effectively to support communication; however, they showed limitations in integrating varied information for cross-modal communication.
