Abstract
PURPOSE
Stories told by autistic narrators often contain relatively frequent use of ambiguous references. However, it remains unclear whether this ambiguity is driven by ambiguous character establishment (e.g., "Once upon a time, she/the girl…") and/or ambiguous cohesion (e.g., "Two girls lived in a castle. She/The girl…"). In this study, we directly compared rates of each type of ambiguity within and between narratives told by autistic and non-autistic children, to determine which type of ambiguity is relatively more common in narratives told by autistic children.
METHOD
Thirty-three 10- to 17-year-old autistic participants (n = 17) and non-autistic peers (n = 16), who were not statistically different in age, standardized language scores, and IQ scores (p > .8 for all), watched two short animated videos alone and then described the videos' events to two listeners who were openly unfamiliar with the videos. We transcribed video recordings of narratives and coded all referential noun phrases (NPs) as either clear or ambiguous. We further categorized ambiguous NPs as either ineffective introduction or ineffective cohesion.
RESULTS
Autistic children produced significantly higher rates of ambiguous establishment than non-autistic peers, whereas between-group comparisons' rates of ambiguous cohesion were not statistically significant.
CONCLUSIONS
Older children on the autism spectrum show differences in the way they introduce characters, selecting NP types that are only appropriate when their listener is already familiar with the referent. In contrast, once they have introduced characters, they show cohesive skills that are comparable to those of non-autistic peers. Findings support theories arguing that autistic children show differences in their application of social pragmatic principles (listener/context-specific pragmatic rules), whereas their use of linguistic pragmatics (context-independent rules) is similar to that of non-autistic peers.
