AbstractRecasting is the adult rephrasing of a child's immediately preceding utterance. It has been shown to have outstanding effects on promoting language development in autistic children. This study used lag sequential analysis to explore the impact of mothers' conversational styles on the communicative behavior of autistic children when using recasting. This study recruited 30 Chinese autistic children (aged 3–6 years) and their mothers. The utterances of the children and their mothers during 30‐min interactions were transcribed, coded, and analyzed. The mothers' conversational styles were determined by the percentages of child‐dominant, mother‐dominant, and equality styles. The results indicated that mothers' conversational styles were predominantly child‐dominant, differing from the expected mother‐dominant style that is typical in Eastern cultures and traditions. However, some mothers still demonstrated a significant proportion of mother‐dominant style in their conversation, while some exhibited a considerable amount of equality style. Moreover, mothers with a mainly child‐dominant style and minimal use of mother‐dominant and equality styles used recasting after the child's response, triggering the child to initiate new topics. Mothers with a child‐dominant style combined with prominent mother‐dominant features implemented untargeted self‐recasting, the children did not respond significantly. Mothers with a child‐dominant style combined with prominent equality features used recasting after the children responded, initiated, or expanded the conversation, which often facilitated the child's expansion of the conversation. These findings provide suggestions for designing parent‐mediated early language interventions for autistic children.
