Previous reports suggested delayed or reduced canonical babbling in infants later diagnosed with autism, but the story may be complicated. We present a prospective study on 44 infants later diagnosed with autism spectrum disorder compared with 127 infants later identified as typically developing who were followed longitudinally with day-long recordings from 0 to 13 months. Eight 5-min segments from each of their recordings were coded for canonical and noncanonical syllables. The results confirmed many reports that canonical babbling is a robust feature of human vocal development in the first year of life, with small overall mean differences in canonical babbling rates between the autism spectrum disorder and typically developing groups beginning around 9?months, primarily in males. Our findings highlight the importance of considering sex differences in vocal communication as part of the early detection and diagnosis of autism when determining the need for communication supports to maximize outcomes. Lay Abstract Our study examined how babies develop their ability to talk to help identify early signs of autism. We looked at babies' production of babbling with mature syllables across the first year of life. Babies usually start producing mature babbling at 7 months of age before they say their first words. Some studies have suggested that babies who are later diagnosed with autism produce this kind of babbling less frequently in their first year of life, but other studies have shown complicated outcomes. In this new study, we followed 44 autistic babies and compared them to 127 typically developing babies. We recorded the babies once every month, all day long, from the time that they were born until they were around 13?months old. Then, we studied their mature babbling from segments of these recordings. We found that the rate at which babies used mature babbling was lower in boys with autism, and higher in girls with autism, compared to babies without autism. This research helps us understand how babies with autism learn to talk. It also raises important questions about differences between boys and girls with autism. Our study can help us improve how scientists and clinicians can identify autism earlier, which could lead to better communication supports for autistic children and their families.

Foundations of Vocal Category Development in Autistic Infants / Pumpki Lei SU in Journal of Autism and Developmental Disorders, 55-3 (March 2025)

Kimbrough OLLER, Auteur Article en page(s) : p.862-872 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The present study compared the infant?s tendency in the first year of life to produce clusters of particular vocal types (squeals, vocants, and growls) in typically developing (TD) and autistic infants. Vocal clustering provides evidence of vocal category formation and may establish a foundation for speech development. Specifically, we compared the extent of vocal clustering across outcome groups and age groups. We also examined the associations between the extent of vocal clustering and later outcomes at 2 years within the autistic group. Randomly selected 5-min segments (27,153 5-min segments total) from 1293 all-day home recordings from 103 TD infants and 44 autistic infants across the first year were humancoded (about 9.75 h of data coded per infant on average) to derive vocal clustering patterns. Fisher?s exact tests were used to compare the occurrence of squeals versus vocants, as well as growls versus vocants, across coded segments. Infants in both groups demonstrated clear clustering patterns of squeals and growls across all age groups. The extent of vocal clustering in the autistic group did not correlate significantly with later language, repetitive behavior, or autism severity outcomes. These findings highlight the robustness of the systematic production of vocal categories across the first year of life. The similarity of the clustering patterns in the TD and autistic groups suggests that vocal category formation through active infant vocal exploration is a robust feature of early speech development.

Sensorimotor Behavior in Individuals With Autism Spectrum Disorder and Their Unaffected Biological Parents / Erin K. BOJANEK in Autism Research, 18-3 (March 2025)

We tested the familiality of sensorimotor impairments in autism across multiple motor behaviors and effector systems and in relation to parental broader autism phenotypic (BAP) characteristics. Fifty-seven autistic individuals (probands), 109 parents, and 89 neurotypical control participants completed tests of manual motor and oculomotor control. Sensorimotor tests varied in their involvement of rapid, feedforward control and sustained, sensory feedback control processes. Subgroup analyses compared families with at least one parent showing BAP traits (BAP+) and those in which neither parent showed BAP traits (BAP?). Results show that probands with BAP? parents (BAP? probands) showed atypical control of rapid oculomotor behaviors, while BAP+ probands showed impairments of sustained manual motor and oculomotor behaviors compared to controls. BAP? parents showed impaired rapid oculomotor and sustained manual motor abilities relative to BAP+ parents and controls. Rapid oculomotor behaviors were highly intercorrelated among probands and their biological parents. These findings indicate that rapid oculomotor behaviors are selectively impacted in BAP? probands and their parents and may reflect a familial likelihood for autism independent of parental autistic traits. In contrast, sustained sensorimotor behaviors were affected in BAP+ probands and BAP? parents, suggesting separate familial pathways associated with autism. Finally, atypical saccade dynamics may serve as strong endophenotypes for autism. These findings provide new evidence that rapid and sustained sensorimotor alterations represent strong but separate familial pathways of inherited likelihood for autism.
