Social communication in children with autism: the relationship between theory of mind and discourse development.
Autistic kids naturally get better at keeping a chat on topic within one year, and you don’t need to wait for false-belief mastery to start pragmatic language work.
01Research in Context
What this study did
The team tracked 20 autistic children for one full year. They tested theory-of-mind skills and recorded free-play conversations at the start and end.
Each child chatted with the same adult while playing with toys. The researchers counted how often the child kept the topic going.
What they found
Every child got better at staying on topic. The average gain was large enough to show up on the stats test.
Theory-of-mind scores and topic skills moved together at each time point. Yet early theory-of-mind scores did not predict who would improve most.
How this fits with other research
Chiu et al. (2023) looked at the kids and saw the opposite pattern. In that study, strong early theory-of-mind scores forecast better social play two years later. The clash is useful: the 2023 paper used parent reports of real-life social acts, while the 2005 paper used lab chat codes. Different yardsticks, different answers.
Naito et al. (2004) also found no link between sentence understanding and false-belief scores in preschoolers. That match supports the idea that language form and social-cognition can develop on separate tracks.
Begeer et al. (2015) showed that short theory-of-mind lessons help kids pass false-belief tests, but the gains stay on the test. Taken together, the three studies tell us: teaching theory-of-mind is easy, seeing it transfer to daily talk is hard.
Why it matters
You can relax about chasing higher theory-of-mind scores as a gatekeeper for conversation goals. Keep running pragmatic language groups even if false-belief tests are flat. Measure progress with real back-and-forth chats, not mental-state quizzes. Pick toys or topics the child already loves and track how many turns they stay on subject. A simple count beats a fancy test for showing growth.

03Original abstract
This longitudinal study investigated the developmental trajectory of discourse skills and theory of mind in 57 children with autism. Children were tested at two time points spaced 1 year apart. Each year they provided a natural language sample while interacting with one parent, and were given standardized vocabulary measures and a developmentally sequenced battery of theory of mind tasks. The language samples were coded for conversational skills, specifically the child's use of topic-related contingent utterances. Children with autism made significant gains over 1 year in the ability to maintain a topic of discourse. Hierarchical regression analyses demonstrated that theory of mind skills contributed unique variance to individual differences in contingent discourse ability and vice versa, when measured concurrently; however, they did not predict longitudinal changes. The findings offer some empirical support for the hypothesis that theory of mind is linked to communicative competence in children with autism.
