Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White;…

The objectives were to characterize behavioral signs of autism spectrum disorder (ASD) in younger siblings of diagnosed children (high-risk; HR) and examine classification features of the Autism Observation Scale for Infants (AOSI). Participants (501 HR and 180 low-risk [LR]) were assessed between 6 and 18 months using the AOSI and at age 3 for…

Talbott, Meagan R.; Young, Gregory S.; Munson, Jeff; Estes, Annette; Vismara, Laurie A.; Rogers, Sally J. – Child Development, 2020
In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication…

Gangi, Devon N.; Boterberg, Sofie; Schwichtenberg, Amy J.; Solis, Erika; Young, Gregory S.; Iosif, Ana-Maria; Ozonoff, Sally – Child Development, 2021
Two independent cohorts (N = 155, N = 126) of infants at high and low risk for autism spectrum disorder (ASD) were followed prospectively between 6 and 36 months of age, when n = 46 were diagnosed with ASD. Gaze to adult faces was coded--during a developmental assessment (Cohort 1) or a play interaction (Cohort 2). Across both cohorts, most…

Edgin, Jamie O.; Tooley, Ursula; Demara, Bianca; Nyhuis, Casandra; Anand, Payal; Spanò, Goffredina – Child Development, 2015
Recent evidence has suggested that sleep may facilitate language learning. This study examined variation in language ability in 29 toddlers with Down syndrome (DS) in relation to levels of sleep disruption. Toddlers with DS and poor sleep (66%, n = 19) showed greater deficits on parent-reported and objective measures of language, including…

Gliga, Teodora; Elsabbagh, Mayada; Hudry, Kristelle; Charman, Tony; Johnson, Mark H. – Child Development, 2012
This study investigated gaze-following abilities as a prerequisite for word learning, in a population expected to manifest a wide range of social and communicative skills--children with a family history of autism. Fifty-three 3-year-olds with or without a family history of autism took part in a televised word-learning task. Using an eye-tracker to…

Developmental Trajectories in Children with and without Autism Spectrum Disorders: The First 3 Years
Landa, Rebecca J.; Gross, Alden L.; Stuart, Elizabeth A.; Faherty, Ashley – Child Development, 2013
Retrospective studies indicate 2 major classes of autism spectrum disorder (ASD) onset: early and later, after a period of relatively healthy development. This prospective, longitudinal study examined social, language, and motor trajectories in 235 children with and without a sibling with autism, ages 6-36 months. Children were grouped as: ASD…

Webb, Sara Jane; Jones, Emily J. H.; Merkle, Kristen; Venema, Kaitlin; Greenson, Jessica; Murias, Michael; Dawson, Geraldine – Child Development, 2011
Individuals with autism spectrum disorder (ASD) show differences in face processing abilities from early in development. To examine whether these differences reflect an atypical versus delayed developmental trajectory, neural responses to familiar and unfamiliar faces in twenty-four 18- to 47-month-old children with ASD were compared with…

Swensen, Lauren D.; Kelley, Elizabeth; Fein, Deborah; Naigles, Letitia R. – Child Development, 2007
Two language acquisition processes (comprehension preceding production of word order, the noun bias) were examined in 2- and 3-year-old children (n=10) with autistic spectrum disorder and in typically developing 21-month-olds (n=13). Intermodal preferential looking was used to assess comprehension of subject-verb-object word order and the tendency…

Peer reviewedBaron-Cohen, Simon; And Others – Child Development, 1997
Two studies of toddlers and children with autism, mentally handicapped children, and normal toddlers examined whether autistic toddlers used Speaker's Direction of Gaze (SDG) strategy or less powerful Listener's Direction of Gaze (LDG) strategy to learn a word for a novel object. Results suggest autistic toddlers are insensitive to speaker's gaze…
