Perception of dialect variation by young adults with high-functioning autism

Area of Science:

• Psycholinguistics
• Neurodevelopmental disorders
• Sociolinguistics

Background:

• Autism spectrum disorder (ASD) is characterized by intact perceptual skills but challenges in social language functions.
• Understanding how individuals with ASD perceive social cues in speech is crucial.

Purpose of the Study:

• To investigate the perception of regional dialects in adults with High-Functioning Autism (HFA).
• To determine if HFA affects the ability to classify dialects and understand associated social stereotypes.

Main Methods:

• Three experiments were conducted with young adults with HFA and a typically developing control group.
• Tasks included regional dialect classification, localness rating, and a language attitudes assessment.

Main Results:

• Participants with HFA performed similarly to controls in classifying dialects and rating localness.
• Individuals with HFA showed reduced ability in differentiating dialects during the language attitudes task.

Conclusions:

• Adults with HFA can utilize indexical speech cues for dialect identification.
• HFA may impact the internalization and application of social stereotypes linked to dialectal variation.
