Inferential talk between teachers and children across play types: a categorization based on the play continuum.

Verbal interactions between teachers and children play a significant role in child development. This study systematically examined the linguistic features and bidirectional dynamics of inferential talk in teacher-child dyads across three play contexts-free play, guided play, and teacher-directed play-based on 54 Chinese preschool play activities categorized according to the play continuum framework. Participants were 41 teachers and up to 637 children from their classroom aged 3-6. By employing a four-level coding scheme of abstraction (i.e., a literal-to-inferential discourse continuum from Level 1 to Level 4), the study revealed significant differences in the level of inferencing in teacher-child language across different play types. Moreover, a significant alignment was found between the level of children's responses and teachers' initiating utterances, as well as between teachers' responses and children's initiations. Each play context displayed distinct bidirectional dynamics: free play was characterized by low-level reciprocity, guided play by matched-level engagement, and teacher-directed play by progressive scaffolding that elevated cognitive complexity. These findings affirm that play types situated along the play continuum modulate cognitive tension through differential distributions of control. The study offers empirical linguistic evidence to support the optimization of multimodal play practices and the enhancement of dialogic quality in early childhood educational settings.
