Irony Comprehension in Children With Cochlear Implants: The Role of Language Competence, Theory of Mind, and Prosody Recognition

Purpose Aims of this research were (a) to investigate higher order linguistic and cognitive skills of Italian children with cochlear implants (CIs); (b) to correlate them with the comprehension of irony, which has never been systematically studied in this population; and (c) to identify the factors that facilitate the development of this competence. Method We tested 28 Italian children with CI (mean chronological age = 101 [ SD = 25.60] months, age range: 60–144 months), and two control groups of normal-hearing (NH) peers matched for chronological age and for hearing age, on a series of tests assessing their cognitive abilities (nonverbal intelligence and theory of mind), linguistic skills (morphosyntax and prosody recognition), and irony comprehension. Results Despite having grammatical abilities in line with the group of NH children matched for hearing age, children with CI lag behind both groups of NH peers on the recognition of emotions through prosody and on the comprehension of ironic stories, even if these two abilities were not related. Conclusions This is the first study that targeted irony comprehension in children with CI, and we found that this competence, which is crucial for maintaining good social relationships with peers, is impaired in this population. In line with other studies, we found a correlation between this ability and advanced theory of mind skills, but at the same time, a deeper investigation is needed, to account for the high variability of performance in children with CI.

Qualitative Differences in Attribution of Mental States to Other People in Autism and Schizophrenia: What are the Tools for Differential Diagnosis?

The differential diagnosis between schizophrenia spectrum disorders (SSD) and autism spectrum disorders (ASD) remains an important clinical question, because they have overlap in clinical diagnosis. This study explored the differences between ASD (n = 44) and SSD patients (n = 59), compared to typically developing peers (n = 63), in completing an advanced Theory of Mind (ToM) task. The outcome found several differences between groups. The SSD patients showed greater difficulty in understanding social scenarios, while ASD individuals understood the stories, but did not correctly identify the protagonist’s intention. The interesting aspect of the results is that some ToM stories are more informative about the mentalistic reasoning of the two clinical groups, namely, the stories that investigate pretend, persuasion, double bluff and ironic joke constructs.
