Is it up to language? Pragmatic competence in Croatian preschool children with autism and typical development

ObjectivesThe relationship between structural language ability and pragmatics is not fully understood, in either individuals with autism or those with typical development (TD). Despite the well-established understanding that core deficits in autism lie in pragmatics, specific pragmatic behaviours that distinguish autistic children (AC) from their TD peers are not sufficiently described. The aims of this study were as follows: to investigate the differences in language abilities and pragmatic competence between AC and those with TD; to examine the relationship between language comprehension/production and pragmatic competence in both groups; and to identify the items of pragmatic composite that are most discriminative in detecting AC.MethodsThe participants in this study were preschool-aged children with TD (N = 45; mean age 65.5 months) and AC with average nonverbal IQ scores (N = 32; mean age 72.9 months). Language production and comprehension abilities were assessed using the New Reynell Developmental Language Scales (4th edition), and pragmatic competence was measured using the Children's Communication Checklist (CCC).ResultsFor all language and pragmatic variables, AC performed worse than those with TD. Pragmatic competencies did not correlate with structural language skills in either group, except for a correlation between language production and coherence in the TD. Finally, certain pragmatic behaviours common to many AC and rarely found in children with TD were identified as potential distinguishing features between the two groups.ConclusionsThis study underscores the importance of incorporating pragmatic assessments alongside traditional language evaluations and suggests that interventions should target pragmatic competence specifically, especially in preschool AC.
