Does teaching theory of mind have an effect on the ability to develop conversation in children with autism?

The team worked with children on the spectrum. They taught classic theory-of-mind tasks like the false-belief test. The goal was to see if passing these tasks later helped kids chat more.

There was no control group. Staff simply measured each child’s conversation before and after the lessons.

Kids learned to pass the tests, but their real talk stayed flat. They did not use more feeling words or longer turns. The program had zero effect on everyday conversation.

Ohan et al. (2015) followed toddlers for seven years. Half of those first labeled low-functioning spoke in full sentences by age nine. Their gains came from natural growth and early ABA hours, not from mind-reading lessons. The new data extend the 1997 null finding by showing that time and good teaching, not theory-of-mind drills, drive later chat.

Aydin et al. (2025) looks like a clash. Brain stimulation lifted social-communication scores after four weeks, while the 1997 lessons did nothing. The gap is in the method: tDCS works on basic brain arousal, not on abstract rules about beliefs. Different paths, different outcomes.

Zheng et al. (2020) echoes the same empty result. Robot-led joint-attention training also failed to budge group-level social skills. Together, the two null studies warn that isolated social-cognition drills rarely transfer to real talk.

Skip stand-alone theory-of-mind lessons. Spend the minutes on functional ABA goals instead: mand training, peer play, and intraverbal fill-ins. Those skills show parents and funders real change during conversation.
