    Abstract In their first three years, children begin to maintain topics and add new information in conversation. In turn, caregivers create opportunities for language learning. Compared to children with no family history of autism (typical likelihood, TL), the younger siblings of children with autism spectrum disorder (ASD) are at elevated likelihood (EL) for both ASD and language delays. This study asked: (1) Do profiles of spoken language and conversational skills differ across groups? (2) Does spoken language relate to conversational skills? and (3) How does parent speech relate to child spoken language and conversational skills? Child spoken language, conversational skills, and parent speech were examined during toy play at home with three-year-old TL (n = 16) and EL children with ASD (EL-ASD, n = 10), non-ASD language delay (EL-LD, n = 21), and no delays or diagnoses (EL-ND, n = 37). EL-ASD children produced fewer intelligible utterances, and EL-LD and EL-ASD children produced shorter utterances than TL and EL-ND children. When utterances were intelligible, all groups were highly contingent to the topic. EL-ASD children were less likely than all other groups to add new information, and adding new information was positively associated with utterance length. Parents of EL-ASD children had fewer opportunities to respond contingently. However, all parents were highly topic-contingent when child speech was intelligible, and parent speech complexity varied with child language and conversational skills. Findings highlight strengths in conversational skills for EL-ASD children during toy play with parents and show that children and caregivers together shape opportunities for developing language and conversation.

    Abstract Infants initiate interactions to get their wants and needs met; but sometimes they are not effective in their communication and are misunderstood by caregivers. When this happens, they must recognize this breakdown in communication and attempt repairs. Experimental literature suggests that in neurotypically developing infants these skills develop during the first two years. However, little work has investigated communication breakdowns and repairs in populations of infants with known social communication difficulties (e.g., infants with an elevated likelihood for autism). Here we explored early social communication initiations, breakdowns, and repair strategies in naturalistic videos of 18-month-old infants (N = 64) with elevated likelihood (EL) for autism and other developmental delays (N = 49) and infants with population-level likelihood for autism (e.g., typical likelihood, TL, N = 15). EL infants, including those who later met criteria for autism (EL-AUT), initiated with caregivers, experienced breakdowns, and made repairs at similar rates to TL infants. However, the types of behaviors used differed, such that EL infants appeared to have a relative strength in making behavior regulation bids. EL-AUT infants used a large proportion of developmentally appropriate repair behaviors (i.e., addition and substitution), even though their repertoires of repair strategies were smaller. Additionally, EL-AUT infants produced a larger proportion of simplification repairs, which are less developmentally advanced and less helpful to interlocutors. Identifying patterns in how EL infants communicate with caregivers and capitalizing on their strengths could improve interventions focused on social communication.

    Abstract In the first years of life, infants rapidly acquire a series of new motor skills. They learn to sit independently, to walk with skill, and to engage in a wide variety of interactions with objects. Over these same years, infants also begin to develop language. These are not isolated events. In a complex developing system, even small changes in one domain can have far-reaching effects on development in other domains. This is the fundamental idea behind the rich framework known as the developmental cascades perspective. Here we employ this framework to show how early motor advances can exert downstream effects on the development of language. Focusing first on the emergence of independent sitting, then on the development of walking, and finally on changes in the ways in which infants act on and combine actions on objects, we describe how the nature and quality of infant actions change dramatically over the first few years and how this brings with it new possibilities for engaging the environment, more sophisticated ways of interacting with people, and significant alterations in communications directed by caregivers to the infant and coordinated with infant action in time and in meaning. The developmental cascades framework provides an approach for understanding how advances in motor skills influence communicative and language development, and more generally, for conceptualizing the constant, dynamic, and complex interplay between developing infants and their environments as it unfolds over time. This article is categorized under: Linguistics > Language Acquisition Psychology > Motor Skill and Performance Psychology > Development and Aging.

    Abstract The first year of life is punctuated by explosions of growth in motor and language abilities. This is not a coincidence. The notion of developmental cascades provides a conceptual framework for considering ways in which advances in one component of a developing system can exert far-reaching and lasting change in other domains. In this article, I review evidence for the cascading effects of early motor advances on the developing communication and language system and describe how variability in the timing of these advances may alter the nature of these effects.

    Abstract Many different pathways can lead to the same result or developmental outcome. What are the developmental routes that result in the onset of walking? In this longitudinal study, we documented patterns of infant locomotion during everyday activities at home for 30 prewalking infants. Using a milestone-based design, we focused on observations spanning the two months before the onset of walking (M age at walk onset = 11.98 months, SD = 1.27). We examined how much time infants spent in motion and when they moved, whether they were more likely to do so while prone (crawling) or upright with support (cruising or supported walking). Results showed immense variability in infants' practice regimes en route to walking-some infants spent relatively similar amounts of time crawling, cruising, and supported walking at each session, others preferred one method of travel over the alternatives, and some switched between different types of locomotion from session to session. In general, however, infants spent a larger share of their movement time in upright positions compared to prone. Finally, our densely sampled dataset revealed a clear feature of locomotor development: infants follow many distinct and variable paths to walk onset, regardless of the age at which it is attained.

    Abstract Lay abstract: Managing negative emotion can be challenging for autistic individuals and their families from a young age. Parents help young children manage negative emotions by responding in comforting or supportive ways. Not much research has examined how negative emotions and parent responses to negative emotions are different in very young autistic children. This study used videotapes of 18-month-old toddlers and parents at home. We examined how much and how intensely toddlers expressed negative emotion in everyday situations, and how parents responded. Participants were younger siblings of autistic children, and we compared three groups-children that (1) later received an autism diagnosis; (2) had language delays but not autism; and (3) had no delays or autism. We found that autistic toddlers' negative emotion was more likely to be intense and to continue once it started compared with children without delays or autism. Language-delayed toddlers also showed some, but not all these differences. Parents responded similarly to negative emotions in all groups. When parents used strategies to help, it reduced the chances of the negative emotions continuing, although it may have been less helpful for autistic toddlers. This study shows that autistic children may express more intense and long-lasting negative emotions from an early age. It also shows that parents of autistic children are very responsive to their children's negative emotions, but these responses may not be as helpful to autistic children. While more research is needed, this study helps us understand how autistic toddlers may express and experience emotions differently.

    Abstract Purpose: The purpose of this scoping review was to examine and analyze the developmental and rehabilitation literature related to movement and participation at key points of transition for individuals with neuromotor conditions.
    Methods: Arksey and O'Malley's scoping review protocol was applied, and 37 articles were included. Extracted data included population, developmental transition points, movement opportunity, type of participation, and outcome measures.
    Results: Most studies covered developmental transition points; none examined transitions as a variable for participation outcomes. Physical activity/exercise was the most common movement opportunity. Most publications used formal outcome measures of participation; others used observation or interviews.
    Conclusion: No publications adequately addressed the effect of movement opportunities on participation during developmental transition points.

    Abstract Purpose: A recent approach to identifying early markers of risk for autism spectrum disorder (ASD) has been to study infants who have an older sibling with ASD. These infants are at heightened risk (HR) for ASD and for other developmental difficulties, and even those who do not receive an eventual ASD diagnosis manifest a high degree of variability in trajectories of development. The primary goal of this review is to summarize findings from research on early motor and communicative development in these HR infants.
    Method: This review focuses on 2 lines of inquiry. The first assesses whether delays and atypicalities in early motor abilities and in the development of early communication provide an index of eventual ASD diagnosis. The second asks whether such delays also influence infants' interactions with objects and people in ways that exert far-reaching, cascading effects on development.
    Results: HR infants who do and who do not receive a diagnosis of ASD vary widely in motor and communicative development. In addition, variation in infant motor and communicative development appears to have cascading effects on development, both on the emergence of behavior in other domains and on the broader learning environment.
    Conclusions: Advances in communicative and language development are supported by advances in motor skill. When these advances are slowed and/or when new skills are not consolidated and remain challenging for the infant, the enhanced potential for exploration afforded by new abilities and the concomitant increase in opportunities for learning are reduced. Improving our understanding of communicative delays of the sort observed in ASD and developing effective intervention methods requires going beyond the individual to consider the constant, complex interplay between developing communicators and their environments.

    Abstract New motor skills supply infants with new possibilities for action and have consequences for development in unexpected places. For example, the transition from crawling to walking is accompanied by gains in other abilities-better ways to move, see the world, and engage in social interactions (e.g., Adolph & Tamis-LeMonda, 2014). Do the developmental changes associated with walking extend to the communicative behaviors of caregivers? Thirty infants (14 boys, 16 girls; 93% White, not Hispanic or Latino) and their caregivers (84% held a college degree or higher) were observed during everyday activities at home during the two-month window surrounding the onset of walking (
