Perception and Production of Statement-Question Intonation in Autism Spectrum Disorder: A Developmental Investigation.
Li Wang, C Philip Beaman, Cunmei Jiang and 1 others
PMID 34355295WHAT IT FOUND
High-functioning individuals with ASD matched controls in identifying, discriminating, and imitating question versus statement intonation.
However, children with ASD had poorer pitch sensitivity. Musical analogues were easier to discriminate than speech for both groups, supporting music as a scaffold.
Key findings
01There were no significant differences between the ASD and control groups in intonation discrimination, identification, or imitation across all age cohorts.
02Children with ASD showed worse pitch direction discrimination thresholds than typically developing children, though this difference was less pronounced in adolescents and adults.
03Both groups performed better at discriminating musical analogues of intonation than natural speech, suggesting shared pitch processing mechanisms.

What it does not show
The sample consisted only of high-functioning individuals with ASD who had age-appropriate language skills, so results may not generalize to those with language impairment or lower cognitive functioning. The study used a cross-sectional design with broad age cohorts, which limits the ability to detect fine-grained developmental changes. The pitch discrimination difference in adults and adolescents received only weak statistical support, making conclusions for these age groups less certain.
Declared interests
The study was funded by the European Research Council.
The easy way to misread this
Do not assume that all individuals with ASD have intact prosody. This study only examined high-functioning speakers with age-appropriate language; those with language impairment or lower cognitive abilities may still show significant deficits.
