Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

We examined adult behavioral skills training (BST) for home-based therapeutic support staff (TSS) using a naturalistic developmental behavioral intervention (NDBI) with young children with Autism Spectrum Disorder (ASD) derived from Project ImPACT. We taught three TSS to use interactive strategies with online modules, in-vivo training, and ongoing…

Approximately 30% of autistic children are considered minimally verbal. The field lacks an efficient and reliable measure of communicative capacity among minimally verbal autistic children. Improved methods are needed to determine which children are at greatest risk for minimally verbal outcomes to better target interventions. Here, we present the…

Background and Aims: Individuals with fragile X syndrome (FXS) characteristically struggle with language and communication throughout the life course, but there is limited research on the development of communication before 24 months. The purpose of this study is to describe the early communication of infants and toddlers with FXS using the…

Robust evidence supports the efficacy of early autism intervention. Despite broad consensus that earlier intervention leads to better outcomes, evidence for this has been limited to correlational studies. This study examined timing effects of the Early Social Interaction (ESI) model, a parent-implemented intervention, using a complete crossover…

This study investigated the feasibility of recruiting and assessing infants with prodromal autism characteristics in the first year of life via telehealth. Participants included 41 infants (Mage = 10.51 months, 51.2% female, 80.5% White) whose parents had concerns about social communication delays or autism. All infants met concerns criteria on a…

Background and Aims: The purpose of this exploratory study was to expand existing literature on prelinguistic vocalizations by reporting results of the first home-based longitudinal study examining a wide variety of behaviors and characteristics, including early vocalizations, across infants at low and elevated risk of autism spectrum disorder…
