When do Children with Autism Spectrum Disorder Take Common Ground into Account During Communication?

"Sure I'll help-I've just been sitting around doing nothing at school all day": Cognitive flexibility and child irony interpretation

Successful peer relations in older children depend on proficiency with banter, which in turn frequently involves verbal irony. Individual differences in successful irony interpretation have traditionally been attributed to theory of mind. Our premise was that the key factor might in fact be cognitive flexibility, that is, the ability to switch between different perspectives (here, on the same utterance). We also wished to extend the focus of previous irony studies, which have almost exclusively examined simple irony, where the literal meaning conflicts with observable physical evidence (e.g., "Great day for a picnic" when viewing a downpour). Therefore, we also examined how children interpreted more complex irony, where listeners must consider at a deeper level the common ground shared with the speakers (e.g., general knowledge/cultural common ground or information about the particular speaker). In Study 1, we found that for 6- to 8-year-olds, both cognitive flexibility and theory of mind contributed unique variance to simple irony interpretation while statistically controlling for nonverbal reasoning and structural language standardized scores. Neither inhibitory control, nor working memory, nor general knowledge correlated with irony interpretation. The 6- to 8-year-olds were at floor for complex irony. In Study 2, we found that cognitive flexibility contributed unique variance to how 10- to 12-year-olds interpreted complex irony while controlling for nonverbal reasoning, structural language, and specific knowledge required. We are the first to examine the relationship with cognitive flexibility and conclude that it must be taken into account when investigating the relationship between theory of mind and irony interpretation.

Toward a Definition of the Linguistic Profile of Children With Autism Spectrum Disorder

The current investigation assessed linguistic and narrative abilities in a cohort of children with Autism Spectrum Disorder (ASD). The linguistic assessment was performed with both traditional tests and a multilevel procedure for discourse analysis. The results showed difficulties at different stages of message planning, organization, and microlinguistic processing (i.e., lexical selection and grammatical processing). Their macrolinguistic impairments were likely related to more general difficulties in the prelinguistic conceptual phase of message planning and mental model generation. Such weaknesses included a difficulty in the non-verbal conceptualization of the story and the generation of an internal representation of the addressee's mental model.
