Role of sentence-final particles and prosody in irony comprehension in Cantonese-speaking children with and without Autism Spectrum Disorders

Abstract

English-speaking children with Autism Spectrum Disorders (ASD) are less capable of using prosodic cues such as intonation for irony comprehension. Prosodic cues, in particular intonation, in Cantonese are relatively restricted while sentence-final particles (SFPs) may be used for this pragmatic function. This study investigated the use of prosodic cues and SFPs in irony comprehension in Cantonese-speaking children with and without ASD. Thirteen children with ASD (8;3–12;9) were language-matched with 13 typically developing (TD) peers. By manipulating prosodic cues and SFPs, 16 stories with an ironic remark were constructed. Participants had to judge the speaker's belief and intention. Both groups performed similarly well in judging the speaker's belief. For the speaker's intention, the TD group relied more on SFPs. The ASD group performed significantly poorer and did not rely on either cue. SFPs may play a salient role in Cantonese irony comprehension. The differences between the two groups were discussed by considering the literature on theory of mind.
