Linguistic construction of social roles in children’s graded readers: a corpus-based study of authority and solidarity

This corpus-based study investigates the linguistic construction of social roles in children’s graded readers through a systematic analysis of 85,000 tokens across five proficiency levels (L1–L5) from the Little Fox English learning platform. Employing Systemic Functional Linguistics and Language Socialisation Theory as our theoretical framework, we examine three critical dimensions of social role representation: (1) the evolution of authority relationships from directive control to negotiated interaction, (2) the development of peer interaction strategies from physical to verbal negotiation, and (3) the progression of anthropomorphism from action-based to psychologically complex characterisation. The mixed-methods approach combines quantitative corpus analysis with qualitative discourse analysis to track the developmental trajectories of key linguistic features including imperatives, mental state verbs, politeness markers, and conflict resolution strategies. The results demonstrate a systematic calibration of linguistic complexity to children’s developing social cognition, with particularly significant transitions occurring between L2–L3 (emergence of perspective-taking) and L4–L5 (development of meta-cognitive abilities). These findings have important implications for understanding how educational materials can scaffold both linguistic and social development in age-appropriate ways.
