“…For instance, parents of ER infants without ASD may interact with their children in a unique way that promotes language development, regardless of their SES. Previous work has shown that ER infants receive different communicative inputs from their parents, such as increased gesture use, attention bids, and follow‐in commenting, all of which may strengthen infants' language skills (Talbott et al, 2015; Wan et al, 2019; Woolard et al, 2022). Another possibility is that ER‐no ASD infants have certain traits that support language development, making them less vulnerable to the impacts of SES.…”

Early predictors of language skills at 3 years of age vary based on diagnostic outcome: A baby siblings research consortium study

While previous work has identified the early predictors of language skills in infants at elevated familial risk (ER) and low familial risk (LR) for autism spectrum disorder (ASD), no studies to date have explored whether these predictors vary based on diagnostic outcome of ASD or no ASD. The present study used a large, multisite dataset to examine associations between a set of commonly studied predictor variables (infant gesture abilities, fine motor skills, nonverbal cognition, and maternal education level), measured at 12 months, and language skills, measured at 3 years, across three diagnostic outcome groups-infants with ASD ("ASD"), ER infants without ASD ("ER-no ASD"), and LR infants without ASD ("LR-no ASD"). Findings revealed that the predictors of language skills differed across groups, as gesture abilities were positively associated with language skills in the ER-no ASD group but negatively associated with language skills in the ASD group. Furthermore, maternal education level was positively associated with language skills in the ASD and LR-no ASD groups only. Variability in these early predictors may help explain why language skills are heterogeneous across the autism spectrum, and, with further study, may help clinicians identify those in need of additional and/or specialized intervention services that support language development.Lay Summary: The present study identified predictors of language skills in infants with and without autism spectrum disorder (ASD). Maternal education level and 12-month gesture abilities predicted 3-year language skills in infants with ASD. Measuring these predictors early in life may help identify infants and families in need of additional and/or specialized intervention services that support language development.

“…When engaging with infants, caregivers naturally use the distinctive speaking style of infant-directed speech (IDS), which is characterized by acoustic features of heightened pitch, exaggerated pitch contours, slower tempo, increased rhythmicity, and increased temporal and pitch variability compared to adult-directed speech (Falk & Kello, 2017;Ferguson, 1964;Fernald, 1991;Katz et al, 1996;Papoušek, 1992;Stern et al, 1982;Trehub et al, 1993;Wang et al, 2018). These features of IDS capture and modulate infant attention and arousal to facilitate social interaction and learning (e.g., such as by using duration, intensity, and pitch accents to accentuate important linguistic information) (Räsänen et al, 2018;Senju & Csibra, 2008;Singh et al, 2009;Thiessen et al, 2005;Woolard et al, 2021).…”

“…For instance, caregivers of infants who are later diagnosed with ASD don't wane their use of IDS as quickly as parents of TD infants (Cohen et al, 2013) suggesting parents continue to use this exaggerated prosodic style of speech to engage and regulate interactions. At the same time, infants at elevated risk for ASD demonstrate reduced attention to IDS compared to their peers (Droucker et al, 2013;Quigley et al, 2016;Watson et al, 2012;Woolard et al, 2021) and preferences for IDS are associated with children's social communicative behaviors and receptive language skills Paul et al, 2007).…”

Timing is critical to successful social interactions. This study investigated temporal structure of vocal interactions longitudinally in parent-child dyads of typically developing (TD) infants (n=49; 9-18 months; 48% male; 81.6% white) and toddlers with ASD (n=23; 27.2±5.0 months; 91.3% male; 65.2% White). Acoustic hierarchical temporal structure (HTS; event clustering across multiple time scales), which reflects temporal complexity and variability, was measured in free play interactions using Allan Factor. Child expressive language significantly predicted HTS (ß=-0.2) longitudinally across TD infants: greater dyadic HTS was associated with lower child language. ASD dyads exhibited greater HTS than nonverbal matched (d=0.41) and expressive language matched TD dyads (d=0.28). Results provide a new window into how language development and social attunement shape parent-child interaction dynamics.

Successful interactions involve conversational partners' flexibly adapting the timing of their behaviors. We measured the temporal patterns of vocalizations in parent-child interactions of typically developing (TD) and autistic infants/toddlers. While language growth made vocal interaction timing more flexible for TD child-parent dyads, it did not for autistic child-parent dyads who exhibited increased clustering of vocal interactions. Both language and social reciprocity play a role in the timing structure and flexibility of smooth interactions.
