The Real-Time Comprehension of Idioms by Typical Children, Children with Specific Language Impairment and Children with Autism

Matthew Walenski and Tracy Love

Objective: We examined on-line auditory idiom comprehension in typically developing (TD) children, children with specific language impairment (SLI), and children with autism. Theories of idiom processing in adults agree on a reliance on lexical/semantic memory for these forms, but differ in their specifics. The Lexical Representation hypothesis claims that literal and non-literal meanings are activated in parallel. The Configuration hypothesis claims that a non-literal meaning will take precedence, such that a literal meaning may not be activated at all.
Method: Children aged 6–16 years listened to sentences containing idioms for a cross-modal priming task. The idioms were ambiguous between an idiomatic and a literal meaning. We looked at priming for both meanings at the offset of the idiom.
Results: TD children (n=14) and children with SLI (n=7) primed for the idiomatic but not literal meaning of the idiom. Children with autism (n=5) instead primed for the literal but not idiomatic meaning.
Conclusions: TD children showed an adult-like pattern, consistent with predictions of the Configuration Hypothesis. Children with SLI showed the typical pattern, whereas the atypical pattern observed for children with autism may reflect a particular deficit with complex material in semantic memory.
