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.

Cross-modal generalization of receptive and expressive vocabulary in children with autism spectrum disorder / Pumpki L. SU in Autism & Developmental Language Impairments, 4 (January-December 2019)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 4 (January-December 2019) Titre : Cross-modal generalization of receptive and expressive vocabulary in children with autism spectrum disorder Type de document : texte imprimé Auteurs : Pumpki L. SU, Auteur ; George CASTLE, Auteur ; Stephen M. CAMARATA, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background and aimsWord learning is an area that poses a particular challenge to children with autism spectrum disorder. A unique challenge for this population is generalization of learned skills across new learning contexts. In clinical settings, a common assumption in teaching vocabulary for children with autism spectrum disorder is that learning in one modality will generalize incidentally to untreated modalities, but very few studies have evaluated the validity of this assumption. The purpose of this study was to investigate receptive and expressive word acquisition and cross-modal generalization in children with autism spectrum disorder.MethodsA single-case parallel treatments design was used to compare word learning and cross-modal generalization in children with autism spectrum disorder. Ten children with autism spectrum disorder were taught unfamiliar vocabulary words in a combined storybook and play intervention. For each child, half of the target words were trained expressively and the other half were trained receptively by random assignment. No direct cross-modal instruction was delivered. A series of probe sessions were completed to assess participants? within-modal learning and cross-modal generalization of vocabulary learning.ResultsAll children learned target words in both receptive and expressive conditions, as evidenced by an average of 80% accuracy across three trials at the end of each intervention. Overall, cross-modal generalization was higher for the expressive-to-receptive direction than for the receptive-to expressive direction. Nine out of ten children demonstrated successful cross-modal generalization on the expressive-to-receptive probes and only three children demonstrated successful cross-modal generalization on the receptive-to-expressive probes. Large variability was observed with regard to number of intervention sessions needed to reach mastery criterion and there were individual patterns of word learning.ConclusionContrary to the assumption that vocabulary learning will be ?automatically? generalized across modalities, results from this study indicate that cross-modal generalization at the word level is not automatic nor consistent in children with autism spectrum disorder, particularly in the receptive-to-expressive direction.ImplicationsThe finding that more children demonstrated expressive-to-receptive generalization than the opposite direction suggests that targeting expressive vocabulary first with the goal of incidentally increasing receptive vocabulary may be more efficient than starting with the receptive modality. Additionally, the finding that not all children demonstrated successful expressive-to-receptive cross-modal generalization indicates that teaching vocabulary in the expressive modality exclusively does not guarantee receptive understanding in this population. We recommend that practitioners periodically monitor children s vocabulary learning in both modalities or set an explicit generalization goal to ensure complete learning of trained words.

We reviewed sample size, number of participants, participant age, and male/female representation. Our analysis yielded relatively few studies with non/minimally verbal children with ASD focusing on verbal expressive communication. Further, we found large inconsistencies in measures used, definitions of "nonverbal" and "minimally verbal", and ages targeted. Guidelines are suggested to create a more uniform assessment protocol with systematic descriptions of early communication learners as a foundational step for understanding the heterogeneity in this group and replicating research findings for this subgroup of children with ASD.

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.

The role of early social motivation in explaining variability in functional language in toddlers with autism spectrum disorder / Pumpki L. SU in Autism, 25-1 (January 2021)  

Public ISBD [article]  inAutism > 25-1 (January 2021) . - p.244-257 Titre : The role of early social motivation in explaining variability in functional language in toddlers with autism spectrum disorder Type de document : texte imprimé Auteurs : Pumpki L.

YODER, Auteur Article en page(s) : p.244-257 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  behavioral measurement  communication and language  development  pre-school children  social cognition and social behavior Index. décimale : PER Périodiques Résumé : About one-third of children with autism spectrum disorder never develop the language that they need in different day-to-day situations. Identifying potential factors that can predict later language development is crucial to understanding why some children with autism spectrum disorder successfully develop language while others do not. This study sought to investigate one of the understudied predictors of language development, social motivation, and to test theories for why this association may occur. Testing the theories requires that we measure children's ability to deliberately and directly communicate with others (i.e. intentional communication) and children's language understanding between the measures of social motivation and later expressive language. We tested 87 children with autism spectrum disorder, aged 14-31 months, at four times over 24 months. We found that children with relatively stronger social motivation had relatively better language use 2 years later. This positive link was partly due to a child's ability to produce intentional communication and to understand language. Although we did not measure parents' talking to their children, a theory that inspired this study suggests that children who use frequent intentional communication probably motivate others to talk with them frequently, which facilitates children's language understanding which leads to the development of expressive language. This theory, if confirmed to be true, can provide guidance for parents who want to help their children learn to talk. Parents could look for intentional communication from their children and respond by talking to their children. Effective intervention on both parent and child targets will likely enhance treatment efficacy. Future work is needed to test these ideas.
