Some (but not all) Pragmatic Inferences are Difficult for Autistic Children

Area of Science:

• Developmental Psychology
• Linguistics
• Neuroscience

Background:

• Autism is often linked to pragmatic language difficulties, particularly with figurative language like metaphors.
• Previous research on scalar implicatures in autism yielded mixed results, questioning general pragmatic deficits.

Purpose of the Study:

• To investigate pragmatic inference abilities in autistic children using novel tasks for both scalar implicatures and metaphors.
• To address methodological limitations in prior studies concerning language demands and task design.

Main Methods:

• Compared autistic children (N=23) with neurotypical children (N=237) using tablet-based tasks.
• Assessed comprehension of scalar implicatures and metaphors, analyzing accuracy and response times.

Main Results:

• Autistic children performed worse on scalar implicature tasks compared to neurotypical peers.
• Autistic children demonstrated similar metaphor comprehension to neurotypical children.
• Differences were consistent across accuracy and response time measures.

Conclusions:

• The findings challenge the notion of a uniform pragmatic deficit in autism.
• A distinction between guided versus spontaneous pragmatic processes may explain the observed pattern.
• This highlights the complexity of pragmatic challenges faced by autistic individuals.
