Coordinated social communication in toddlers with and without autism spectrum disorder during a home observation

Verbal Responsiveness in Parents of Toddlers With and Without Autism During a Home Observation

This study examined patterns of verbal responsiveness in parents of toddlers (Mage = 20 months) later identified with autism (n = 121), developmental delay (n = 46), or typical development (n = 44) during an hourlong home observation. Parent verbal responsiveness (PVR) was compared using MANOVA across groups and by child expressive language phase. Multiple regression analyses controlling for child age and maternal education were employed to examine the extent to which PVR predicted variance in concurrent child social communication and prospective language skills. Parents provided synchronous responses approximately 90% of the time. Parents of children with autism and developmental delay used smaller proportions of responses that added linguistic information (i.e., expansions and follow-in directives for language) than those of children with typical development. Parents of children in the preverbal phase were more likely, on average, to affirm their children's acts of intentional communication or provide a follow-in directive for action that did not necessitate a verbal response than to expand or elicit language. Regression results indicated that parental use of expansions and follow-in directives for language made significant contributions to child language outcomes. The patterns we observed may reflect parents' attunement to their child's developmental level. Responsiveness to a child's focus of attention is vital in the earlier stages of language learning; however, results point to the potential importance of parental expansions and follow-in directives for promoting language development across groups in this sample. Directions for intervention research targeting PVR and language skills in toddlers with autism and developmental delays are discussed.

Infants who develop autism show smaller inventories of deictic and symbolic gestures at 12 months of age

Gestures are an important social communication skill that infants and toddlers use to convey their thoughts, ideas, and intentions. Research suggests that early gesture use has important downstream impacts on developmental processes, such as language learning. However, autistic children are more likely to have challenges in their gestural development. The current study expands upon previous literature on the differences in gesture use between young autistic and non-autistic toddlers by collecting data using a parent-report questionnaire called the MCDI-Words and Gestures at three time points, 12, 18, and 24 months of age. Results (N = 467) showed that high-likelihood infants who later met diagnostic criteria for ASD (n = 73 HL-ASD) have attenuated gesture growth from 12 to 24 months for both deictic gestures and symbolic gestures when compared to high-likelihood infants who later did not meet criteria for ASD (n = 249 HL-Neg) and low-likelihood infants who did not meet criteria for ASD (n = 145 LL-Neg). Other social communicative skills, like play behaviors and imitation, were also found to be impacted in young autistic children when compared to their non-autistic peers. Understanding early differences in social communication growth before a formal autism diagnosis can provide important insights for early intervention.

The importance and challenges of observing social interactions in autistic preschoolers during inclusive educational settings: A scoping review

Background and aims

A growing number of autistic children have access to inclusive education programs as early as kindergarten. However, little is known about how they actually participate in social interactions and develop their communicative skills according to the parameters of this environment. The aim of this article is to review observational studies on this topic and critically analyze their methodological choices by arguing on the aspects of communication skills noted in the observation grids. Disparities in the information collected depending on the method used have implications for understanding and supporting autistic children in an inclusive school environment.

Methods

Observational studies on social interactions of autistic preschoolers within inclusive preschool settings were scoped. The studies were analyzed according to the following parameters: aims of observation, method used for coding, communication partners considered (adults and peers), type of children's social engagement (initiatives and responses), diversity of communicative forms and communication functions, distinction and comparison of interactional contexts related to the activities, and whether changes linked to developmental variables are studied on an interindividual or longitudinal basis.

Results

Seventeen studies using the observation method in inclusive preschool settings were identified. Recordingmethods are mostly based on video recording. The coding grids mainly focus on autistic children while partners' behaviors (adults, peers) are often coded in less detail, thus providing littleinformation on their dynamic role in the interactions. Overall, autistic children were found to initiate interactions much less often than they respond to it. The data generally distinguish thecommunicative forms used by children and indicate a predominance of nonverbal means at preschool level. However, a few studies coded communicative functions, whether they areaddressed to children or produced by them. In addition, very few studies compare interactions across activity contexts. In addition, very few studies compare interactions across activity contexts.Results of some studies showed that children initiated interaction more frequently during free play than during work activity, but results are heterogeneous. Developmental trajectories in socialskills seem to be associated with the severity of autism and language skills, but longitudinal designs are still rare.

Conclusions and implications

Direct and fine-grained observation in the classroom is a key source of information about how communication takes place in preschool-inclusive settings. The data, despite some methodological challenges, offer opportunities for better adjustment based on professional objectives. Our review highlights the importance of offering occasions for initiatives to autistic children and training of neurotypical peers to better interact with autistic children and promote verbal communication. Further observational studies are needed to use more microanalytic measures of the functional quality of social interactions in autistic children, including joint comparisons between partners (adults vs. peers) and across contexts (e.g., play vs. structured development) so that appropriate strategies can be proposed in inclusive preschool settings.
