Conversational Topic Shifts and Topic Maintenance in Autistic and Neurotypical Children.

The study included 43 autistic and 46 neurotypical children, which is a modest sample and may not represent the broader autistic population. The autistic group had 38 male and 5 female participants, so sex differences could not be analysed. Neurotypical children did not receive standardized language or cognitive tests because of school time constraints, so the groups were not strictly matched on these abilities. Most conversations with autistic children lasted 30 minutes, while conversations with neurotypical children averaged 22 minutes, so response counts may be affected by conversation length. The study examined experimenter-child conversations, not child-child or familiar-partner conversations, so it may not show how topic shifts work in peer interaction. The adult rating task used a small number of items per participant, so the naturalness groupings may need replication. All children were Spanish-speaking, so the study does not show whether the same pattern occurs in other languages or cultures.

The authors declared no conflicts of interest. The study was partially funded by MICIU/AEI, ERDF/EU, the Basque Government, a predoctoral grant from the Basque Government, and an FNRS-F.R.S. WelChange grant.

Do not read the lower naturalness ratings as proof that topic shifts cause negative peer impressions. The study did not test peer reactions or an intervention. It found that autistic children maintained topics similarly but shifted topics more often.
