Abstract
PURPOSE The current study examined the predictive role of gestures and gesture-speech combinations on later spoken language outcomes in minimally verbal (MV) autistic children enrolled in a blended naturalistic developmental/behavioral intervention (Joint Attention, Symbolic Play, Engagement, and Regulation [JASPER] + Enhanced Milieu Teaching [EMT]). METHOD Participants were 50 MV autistic children (40 boys), ages 54-105 months (M = 75.54, SD = 16.45). MV was defined as producing fewer than 20 spontaneous, unique, and socially communicative words. Autism symptom severity (Autism Diagnostic Observation Schedule-Second Edition) and nonverbal cognitive skills (Leiter-R Brief IQ) were assessed at entry. A natural language sample (NLS), a 20-min examiner-child interaction with specified toys, was collected at entry (Week 1) and exit (Week 18) from JASPER + EMT intervention. The NLS was coded for gestures (deictic, conventional, and representational) and gesture-speech combinations (reinforcing, disambiguating, supplementary, other) at entry and spoken language outcomes: speech quantity (rate of speech utterances) and speech quality (number of different words [NDW] and mean length of utterance in words [MLUw]) at exit using European Distributed Corpora Project Linguistic Annotator and Systematic Analysis of Language Transcripts. RESULTS Controlling for nonverbal IQ and autism symptom severity at entry, rate of gesture-speech combinations (but not gestures alone) at entry was a significant predictor of rate of speech utterances and MLUw at exit. The rate of supplementary gesture-speech combinations, in particular, significantly predicted rate of speech utterances and NDW at exit. CONCLUSION These findings highlight the critical importance of gestural communication, particularly gesture-speech (supplementary) combinations in supporting spoken language development in MV autistic children.

Abstract
Children can be reliably diagnosed with autism as early as 3 years of age, and early interventions are initiated. There is often a significant gap between the age of onset of symptoms (2-3 years) and diagnosis (8-10 years) in Africa. We conducted a study to validate the Social Communication Questionnaire (SCQ) as a screening instrument in a rural setting in Kenya. The study was conducted along the Kenyan Coast. Study participants included 172 children with a neurodevelopmental disorder (NDD) diagnosis (84 of which were autism) and 112 controls. Internal consistency was evaluated through the use of Cronbach's alpha, confirmatory factor analysis (CFA) with maximum likelihood procedure to assess the conceptual model for the SCQ. Additionally, the sensitivity and specificity of cut-off scores using ROC analysis and item difficulties and discrimination quality using an IRT framework were also assessed. Factor analysis revealed an adequate fitting model for the three-factor DSM-IV-TR (root mean squared error of approximation (RMSEA) = 0.050; Comparative Fit Index (CFI) = 0.974; Tucker-Lewis Index (TLI) = 0.973) and two-factor DSM-5 factor structure (RMSEA = 0.050; CFI = 0.972; TLI = 0.974). The reliability coefficient alphas for the whole group for all items (Cronbach's α = 0.90) and all three domains (Cronbach's α = 0.68-0.84) were acceptable to excellent. The recommended cut-off score of 15 yielded 72% sensitivity and 100% specificity in the ASD group compared to the typically developing group. We provide early evidence of the adequate factor structure and good internal consistency of the SCQ. We also note that the recommended cut-off yielded sufficient predictive validity.

Abstract
Joint attention and imitation are thought to facilitate a developmental cascade of language and social communication skills. Delays in developing these skills may affect the quality of children's social interactions and subsequent language development. We examined how responding to joint attention and object imitation skills predicted rate of expressive and receptive communication growth rate in a heterogeneous sample of autistic children. Children's baseline skills in responding to joint attention uniquely predicted expressive, but not receptive, language growth rate over time, while object imitation did not significantly predict language growth rate over and above joint attention skills. Future research should examine the potential moderating roles of child age and developmental level in explaining associations between joint attention and object imitation and later language development.

Abstract
LAY ABSTRACT The types of outcomes studied in children on the autism spectrum include clinical characteristics, such as social functioning, communication, language, or autism symptoms. Research that measures these outcomes at multiple timepoints is useful to improve our understanding of what to expect as children develop. In trajectory studies, researchers assess outcomes at three or more timepoints. This method has advantages over two-timepoint studies because it allows researchers to describe changes in the speed of development, such as accelerations, plateaus, or slowdowns. We identified and reviewed 103 published trajectory studies in children (to age 18 years) with an autism diagnosis. Importantly, we did not include studies of treatments or their effects, nor did we summarize the results of studies. Instead, this review summarizes the characteristics of the available published research, including the methods used, the many different outcomes that have been studied over time and the ages over which they have been studied. This summary may be of interest to autistic people and caregivers (parents) who want to know about the existence of research that provides answers about what to expect during an autistic child's development. We have recommended that future trajectory research efforts try to make up for the lack of studies from low- and middle-income countries; that more attention is given to the following outcomes that are meaningful to caregivers and autistic people; and to try to fill in the age gaps where more outcome-specific data are needed.

Abstract
This meta-analysis examined correlations between eye-tracking measures of gaze behaviors manifested during dynamic salient social stimuli and behavioral assessment measures of social communication skills of young autistic children. We employed a multilevel model with random effects to perform three separate meta-analyses for correlation between social communication skills and (a) all gaze behaviors, (b) gaze duration, and (c) gaze transition. Subsequently, we performed meta-regression to assess the role of four moderators, including age, continuum of naturalness of stimuli, gaze metric, and area of interest, on correlation effect sizes that were heterogeneous at the population level. A total of 111 correlation coefficients from 17 studies for 1132 young autistic children or children with high-likelihood for autism (Mage range = 6-95 months) were included in this meta-analysis. The correlation effect sizes for all three meta-analyses were significant, supporting the relation between improved gaze behaviors and better social communication skills. In addition, age, gaze metric, and area of interest were significant moderators. This suggests the importance of identifying meaningful gaze behaviors related to social communication skills and the increasingly influential role of gaze behaviors in shaping social communication skills as young autistic children progress through the early childhood stage. The continuum of naturalness of stimuli, however, was revealed to trend towards having a significant moderating effect. Lastly, it is important to note the evidence of potential publication bias. Our findings are discussed in the context of early identification and intervention and unraveling the complex nature of autism.

Abstract
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.

Abstract
Individuals with Williams Syndrome (WS) have a specific and atypical neuropsychological profile, where language is above what is expected for their mental age, although it shows a late onset. There exists only one longitudinal study in infants younger than 20 months old with WS about early language precursors (joint attention, referential and instrumental behaviors, pointing gesture, verbal tags). The aim of this investigation is to evaluate these precursors in a baby with WS (8 to 18 months). Seven sessions of systematic observation were performed (six at baby's home, one at the Early Childhood Assistance center). The Battelle Developmental Inventory was used to evaluate the baby's development in two occasions (12 and 18 months). The results show an atypical development, and he is 5-6 months under what is expected for his chronological age. Attention towards objects prevails over preference for faces, but this one tends to increase. The pointing gesture does not emerge at the end of the observation period and therefore follows the first words that appear. The implications for the comprehension of the early linguistic profile in WS are discussed, as well as the implications for specific intervention strategies in the context of early childhood care.

Abstract
This study examined the effects of an intervention package using high-tech augmentative and alternative communication (AAC) with Naturalistic Instruction (NI), time delay, and prompting during social routines for preschoolers on the autism spectrum. The AAC was a communication application on a tablet programmed with color photo representations of participants and communication partners engaged in social routines. The primary dependent measure was a linguistic communication turn on the AAC device completing the instructor's cloze phrase related to the routine. A secondary dependent measure was prelinguistic communication -nonspecific vocalizations and smiling - within each turn of the routine. Results indicated that all communication types increased and maintained for all three participants with two participants meeting mastery criteria within the minimal number of sessions. These results are significant in providing additional evidence for the effectiveness of AAC intervention beyond teaching simple object requests and in teaching more socially meaningful communication to children on the autism spectrum. Additionally, this study supports the use of color photo representations to promote social interaction. Future research should continue to evaluate such interventions on a larger scale and include naturally occurring communication partners, such as siblings and peers.

Abstract
Language profiles in autism are variable and atypical, with frequent speech onset delays, but also, in some cases, unusually steep growth of structural language skills. Joint attention is often seen as a major predictor of language in autism, even though low joint attention is a core characteristic of autism, independent of language levels. In this systematic review of 71 studies, we ask whether, in autism, joint attention predicts advanced or only early language skills, and whether it may be independent of language outcomes. We consider only conservative estimates, and flag studies that include heterogenous samples or no control for non-verbal cognition. Our review suggests that joint attention plays a pivotal role for the emergence of language, but is also consistent with the idea that some autistic children may acquire language independently of joint attention skills. We propose that language in autism should not necessarily be modelled as a quantitative or chronological deviation from typical language development, and outline directions to bring autistic individuals' atypicality within the focus of scientific inquiry.

Abstract
How non-autistic persons modulate their speech rhythm while talking to autistic (AUT) individuals remains unclear. We investigated two types of phonological characteristics: (1) the frequency power of each prosodic, syllabic, and phonetic rhythm and (2) the dynamic interaction among these rhythms using speech between AUT and neurotypical (NT) individuals. Eight adults diagnosed with AUT (all men; age range, 24-44 years) and eight age-matched non-autistic NT adults (three women, five men; age range, 23-45 years) participated in this study. Six NT and eight AUT respondents were asked by one of the two NT questioners (both men) to share their recent experiences on 12 topics. We included 87 samples of AUT-directed speech (from an NT questioner to an AUT respondent), 72 of NT-directed speech (from an NT questioner to an NT respondent), 74 of AUT speech (from an AUT respondent to an NT questioner), and 55 of NT speech (from an NT respondent to an NT questioner). We found similarities between AUT speech and AUT-directed speech, and between NT speech and NT-directed speech. Prosody and interactions between prosodic, syllabic, and phonetic rhythms were significantly weaker in AUT-directed and AUT speech than in NT-directed and NT speech, respectively. AUT speech showed weaker dynamic processing from higher to lower phonological bands (e.g. from prosody to syllable) than NT speech. Further, we found that the weaker the frequency power of prosody in NT and AUT respondents, the weaker the frequency power of prosody in NT questioners. This suggests that NT individuals spontaneously imitate speech rhythms of the NT and AUT interlocutor. Although the speech sample of questioners came from just two NT individuals, our findings may suggest the possibility that the phonological characteristics of a speaker influence those of the interlocutor.

Abstract
Term and preterm neonates were assessed at the newborn (NB) period (term, term equivalent) and at 2, 4, 6, and 9 months in a study of the psychometric properties of the Social/Communication/Cognition (SCG) domain of PediaTrac™ v3.0, a novel caregiver-based developmental monitoring instrument. Item response theory (IRT) was used to model item parameters and estimate theta, an index of the latent trait, social/communication/cognition. Exploratory factor analysis (EFA) was conducted to further clarify the dimensionality of the domain. In a cohort of 571 caregiver-infant dyads (331 term, 240 preterm), mean theta values could be reliably estimated at all time periods, with term infants demonstrating significantly more advanced social/communication/cognition abilities at 9 months of age. Item discrimination and item difficulty of the 15, 15, 35, 47, and 57 items at the NB, 2-, 4-, 6-, and 9-month periods, respectively, could be reliably modeled across the range of ability. Total Information for the SCG domain was high and the reliability ranged from 0.97 to 0.99 (NB = .98, 2 month = .97, 4 month = .98, 6 month = .99 and 9 month = .99). EFA revealed second-order factors at each time period, with two factors at the NB period (affect/emotional expression, social responsiveness) accounting for 43% of variance; three factors at 2, 4, and 6 months (affect/emotional expression, social responsiveness imitation/emerging communication), accounting for 43%, 34%, and 34% of the variance, respectively; and four factors at 9 months (imitation/communication, nonverbal/gestural communication, affect expression, and social responsiveness), accounting for 34% of the variance.

Abstract
BACKGROUND Difficulty with imitative gesturing is frequently observed as a clinical feature of autism. Current practices for assessment of imitative gesturing ability-behavioral observation and parent report-do not allow precise measurement of specific components of imitative gesturing performance, instead relying on subjective judgments. Advances in technology allow researchers to objectively quantify the nature of these movement differences, and to use less socially stressful interaction partners (e.g., robots). In this study, we aimed to quantify differences in imitative gesturing between autistic and neurotypical development during human-robot interaction. METHODS Thirty-five autistic (n = 19) and neurotypical (n = 16) participants imitated social gestures of an interactive robot (e.g., wave). The movements of the participants and the robot were recorded using an infrared motion-capture system with reflective markers on corresponding head and body locations. We used dynamic time warping to quantify the degree to which the participant's and robot's movement were aligned across the movement cycle and work contribution to determine how each joint angle was producing the movements. FINDINGS Results revealed differences between autistic and neurotypical participants in imitative accuracy and work contribution, primarily in the movements requiring unilateral extension of the arm. Autistic individuals imitated the robot less accurately and used less work at the shoulder compared to neurotypical individuals. INTERPRETATION These findings indicate differences in autistic participants' ability to imitate an interactive robot. These findings build on our understanding of the underlying motor control and sensorimotor integration mechanisms that support imitative gesturing in autism which may aid in identifying appropriate intervention targets.

Abstract
This longitudinal study examined early predictors of language development in 74 young children with Autism Spectrum Disorder (ASD) in Taiwan. Participants were assessed twice (initial age between 17 and 35 months) on responding to joint attention (RJA), initiating joint attention (IJA), motor imitation with objects (object imitation; OI) and without objects (manual imitation; MI), and receptive and expressive language. The two assessments were 18 months apart. Results showed that both RJA and MI concurrently and longitudinally predicted receptive and expressive language across the two assessments. These findings were not entirely consistent with the limited and mixed findings of Western longitudinal studies. However, they have implications for early interventions aiming to facilitate language development in children with ASD internationally.

Abstract
IMPORTANCE Play is an area of difficulty for autistic children, and occupational therapy practitioners need evidence to guide interventions to improve play for this population. Ayres Sensory Integration® (ASI) intervention has not yet been studied for its impact on play outcomes. OBJECTIVE To examine the impact of ASI intervention on play types in autistic children. DESIGN Nonconcurrent, multiple-baseline design across subjects. SETTING Outpatient occupational therapy clinic in New England. PARTICIPANTS Three autistic children, ages 5, 6, and 6 yr. INTERVENTION Twenty-four ASI sessions. OUTCOMES AND MEASURES Frequency of play type was coded using partial interval coding. Progress monitoring used Goal Attainment Scaling. RESULTS All three participants demonstrated changes in the frequency of specific types of play, but changes varied among them. CONCLUSIONS AND RELEVANCE Findings suggest that ASI intervention may alter a child's patterns of play. What This Article Adds: This study is the first to examine the impact of ASI on play and the third that documents the feasibility of single-subject research for studying ASI. If confirmed in future studies, ASI could become an evidence-based intervention for improving play, an important outcome for autistic children and the profession of occupational therapy. Positionality Statement: This article uses the identity-first language autistic people. This nonableist language describes their strengths and abilities and is a conscious decision. This language is favored by autistic communities and self-advocates and has been adopted by health care professionals and researchers (Bottema-Beutel et al., 2021; Kenny et al., 2016).

Abstract
Individuals with autism spectrum disorders (ASD) have shown impaired performance in canonical and nonsocial working memory (WM). However, no study has investigated social WM and its early development. Using biological motion stimuli, our study assessed the development of social and nonsocial WM capacity among children with or without ASD across the age span between 4 and 6 (N = 150). While typically developing (TD) children show a rapid development from age 5 to 6, children with ASD showed a delayed development for both social and nonsocial WM capacity, reaching a significant group difference at age 6. Furthermore, we found a negative correlation between social (but not nonsocial) WM capacity and the severity of autistic symptoms among children with ASD. In contrast, there is a positive correlation between both types of WM capacity and intelligence among TD children but not among children with ASD. Our findings thus indicate that individuals with ASD miss the rapid development of WM capacity in early childhood and, particularly, their delayed social WM development might contribute to core symptoms that critically depend on social information processing.

Abstract
Background and aims Peer-mediated interventions (PMIs) are effective strategies to foster socialization of children with autism spectrum disorder (ASD) in natural settings. However, research examining the efficacy of peer mediation for students with ASD who have the greatest cognitive and language impairments remains limited. Additionally, previous studies essentially targeted communicative abilities of participants. To address this gap, the present study evaluated the effects of a play-based PMI on three socio-communicative skills (play, social engagement and imitation) of minimally verbal students with ASD who also have a comorbidity of intellectual disability (ID). Methods Seven children with ASD attending ordinary school settings and 14 typically developing (TD) preschoolers participated. Seven single-sex groups were formed, and children played together during two 30 min weekly sessions. TD children were trained according to the principles of the integrated play group model. We used a multiple-baseline design across participants to measure the effects of the intervention on play skills, social engagement and motor imitation of students with ASD. Results Outcomes revealed an intervention effect for most of the participants, despite some variations across children. After the peer training, four children increased their duration of functional/symbolic play, six children improved their duration of interactive play and five children increased their rates of motor imitation. Concerning maintenance gains, inter-individual differences are also important. Conclusions and implications These findings suggest that a play-based PMI may be a feasible option for targeting inclusive education and improving socio-communicative skills of some minimally verbal students with ASD who also have an ID. However, variations across children invite further research to clarify how individual factors can moderate the effects of PMIs in children with ASD who are the most impaired.

Abstract
This meta-analysis examined communication outcomes in single-case design studies of augmentative and alternative communication (AAC) interventions and their relationship to participant characteristics. Variables addressed included chronological age, pre-intervention communication mode, productive repertoire, and pre-intervention imitation skills. Investigators identified 114 single-case design studies that implemented AAC interventions with school-aged individuals with autism spectrum disorder and/or intellectual disability. Two complementary effect size indices, Tau(AB) and the log response ratio, were applied to synthesize findings. Both indices showed positive effects on average, but also exhibited a high degree of heterogeneity. Moderator analyses detected few differences in effectiveness when comparing across diagnoses, age, the number and type of communication modes, participant's productive repertoires, and imitation skills to intervention.

Abstract
The early emergence of social communication challenges and their impact on language in infants later diagnosed with autism has sparked many early intervention programs that target social communication skills. While research has consistently shown lower scores on social communication assessments in the first year of life, there is limited research at 12-months exploring associations between different dimensions of social communication and later language. Understanding associations between early social communication skills and language would enhance our ability to choose high priority intervention goals that will impact downstream language skills. The current study used a standardized assessment to profile social communication skills across 516 infants with a high (HL) or low likelihood (LL-Neg) for autism (84% White, 60% Male), based on the presence of a sibling with autism in the family. The primary aim of the study was to profile social communication skill development in the second year of life and to evaluate associations between social communication skills and later language. HL infants who met criteria for autism (HL-ASD, N = 81) demonstrated widespread reductions in social communication skills at 12-months compared to HL infants who did not meet criteria for autism (HL-Neg, N = 277) and LL-Neg (N = 158) infants. Across all infants in the study, those with better social communication skills at 12-months had better language at 24-months. However, within group analyses indicated that infants who met criteria for autism did not show this developmental coupling until 24-months-of-age at which point social communication was positively associated with downstream language skills. The cascading pattern of reduced social communication skills as well as overall significant positive associations with later language provide further evidence for the need to support developing social communication skills prior to formal autism diagnosis, a goal that could possibly be reached through pre-emptive interventions.

Abstract
While previous work has identified the early predictors of language skills in infants at elevated familial risk (ER) and low familial risk (LR) for autism spectrum disorder (ASD), no studies to date have explored whether these predictors vary based on diagnostic outcome of ASD or no ASD. The present study used a large, multisite dataset to examine associations between a set of commonly studied predictor variables (infant gesture abilities, fine motor skills, nonverbal cognition, and maternal education level), measured at 12 months, and language skills, measured at 3 years, across three diagnostic outcome groups-infants with ASD ("ASD"), ER infants without ASD ("ER-no ASD"), and LR infants without ASD ("LR-no ASD"). Findings revealed that the predictors of language skills differed across groups, as gesture abilities were positively associated with language skills in the ER-no ASD group but negatively associated with language skills in the ASD group. Furthermore, maternal education level was positively associated with language skills in the ASD and LR-no ASD groups only. Variability in these early predictors may help explain why language skills are heterogeneous across the autism spectrum, and, with further study, may help clinicians identify those in need of additional and/or specialized intervention services that support language development. LAY SUMMARY: The present study identified predictors of language skills in infants with and without autism spectrum disorder (ASD). Maternal education level and 12-month gesture abilities predicted 3-year language skills in infants with ASD. Measuring these predictors early in life may help identify infants and families in need of additional and/or specialized intervention services that support language development.

Abstract
This study examined the construct validity of the Autism Classification System of Functioning: Social Communication (ACSF). Participants included 145 parents of children with autism (2-19 years). The degree of convergent and discriminant validity between parent reported ACSF and subscales from Social Responsiveness Scale 2nd edition and Behavior Assessment System for Children, 3rd Edition were examined against a priori hypotheses. We examined construct validity in the entire sample as well as in specific age cohorts. Our findings suggest that ACSF can provide a valid classification system of social communication ability in children with autism 2-19 years of age, and its two subscales may be used to examine different aspects of social communication ability.

Children with ASD establish joint attention during free-flowing toy play without face looks. Curr Biol 2022; 32:2739-2746.e4.

Abstract
Children's ability to share attention with another person (i.e., achieve joint attention) is critical for learning about their environments in general1-3 and supporting language and object word learning in particular.1,4-14 While joint attention (JA) as it pertains to autism spectrum disorder (ASD) is often more narrowly operationalized as arising from eye gaze or explicit pointing cues alone,2,5,10,15-19 recent evidence demonstrates that JA in natural environments can be achieved more broadly through multiple other pathways beyond gaze and gestures.2,4,20-31 Here, we use dual head-mounted eye tracking to examine pathways into and characteristics of JA episodes during free-flowing parent-child toy play, comparing children with ASD to typically developing (TD) children. Moments of JA were defined objectively as both the child's and parent's gaze directed to the same object at the same time. Consistent with previous work in TD children,4,21,25,30-32 we found that both TD and ASD children rarely look at their parent's face in this unstructured free play context. Nevertheless, both groups achieved similarly high rates of JA that far exceeded chance, suggesting the use of alternative pathways into JA. We characterize these alternate pathways, find they occur at similar levels across both groups, and achieve similar ends: namely, for both groups, targets of JA are named more frequently by parents in those moments than non-jointly attended objects. These findings broaden the conceptualization of JA abilities and impairment in ASD and raise questions regarding the mechanistic role of the face-gaze-mediated JA pathway in ASD.

Abstract
This article introduces a three-axis framework indicating how AI can be informed by biological examples of social learning mechanisms. We argue that the complex human cognitive architecture owes a large portion of its expressive power to its ability to engage in social and cultural learning. However, the field of AI has mostly embraced a solipsistic perspective on intelligence. We thus argue that social interactions not only are largely unexplored in this field but also are an essential element of advanced cognitive ability, and therefore constitute metaphorically the “dark matter” of AI. In the first section, we discuss how social learning plays a key role in the development of intelligence. We do so by discussing social and cultural learning theories and empirical findings from social neuroscience. Then, we discuss three lines of research that fall under the umbrella of Social NeuroAI and can contribute to developing socially intelligent embodied agents in complex environments. First, neuroscientific theories of cognitive architecture, such as the global workspace theory and the attention schema theory, can enhance biological plausibility and help us understand how we could bridge individual and social theories of intelligence. Second, intelligence occurs in time as opposed to over time, and this is naturally incorporated by dynamical systems. Third, embodiment has been demonstrated to provide more sophisticated array of communicative signals. To conclude, we discuss the example of active inference, which offers powerful insights for developing agents that possess biological realism, can self-organize in time, and are socially embodied.

Abstract
Children born with a variety of environmental or medical risk factors may exhibit delays in global development. Very often, such delays are identified at preschool or school age, when children are severely overdue for effective early interventions that can alleviate the delays. This chapter proposes a conceptual model of child development to inform the creation of interventions and rehabilitative technologies that can be provided very early in development, throughout the first year of life, to optimize children's future developmental outcomes. The model suggests that early sensorimotor skills are antecedent and foundational for future motor, cognitive, language, and social development. As an example, this chapter describes how children's early postural control and exploratory movements facilitate the development of future object exploration behaviors that provide enhanced opportunities for learning and advance children's motor, cognitive, language, and social development. An understanding of the developmental pathways in the model can enable the design of effective intervention programs and rehabilitative technologies that target sensorimotor skills in the first year of life with the goal of minimizing or ameliorating the delays that are typically identified at preschool or school age. Specific examples of early interventions and rehabilitative technologies that have effectively advanced children's motor and cognitive development by targeting early sensorimotor skills and behaviors are provided.

Early measurement of autism risk constructs in the general population: A new factor structure of the First Years Inventory (FYIv3.1) for ages 6-16 months. Autism Res 2022; 15:915-928.

Abstract
Early detection of autism risk in the community is critical to increasing families' access to early intervention, yet few measures have been developed and tested for the general population of infants <16 months to tap a broader range of autism risk constructs. This study aimed to (a) examine the factor structure of the First Years Inventory, version 3.1 (FYIv3.1), with a sample of 6454 infants 6–16 months, and (b) determine the ability of the resulting factors to discriminate clinical outcome groups at 3 years of age. The FYIv3.1 is a parent‐report tool designed to detect early behavioral risk signs that may be associated with a later diagnosis of ASD and related neurodevelopmental conditions. Factor analytic models were used to determine the number of constructs and inter‐factor correlations. Findings supported a seven‐factor structure: communication, imitation and play (CIP); social attention and affective engagement (SAE); sensory hyperresponsiveness (HYPER); sensory hyporesponsiveness (HYPO); self‐regulation in daily routines (SREG); sensory interests, repetitions, and seeking behaviors (SIRS); motor coordination and milestones (MCM). Mean comparisons on these factors demonstrated significant discrimination of the three outcome groups at age 3 years including those classified as having an ASD diagnosis and/or high autism symptoms, those classified as having other developmental disorders/conditions/concerns, and those classified with no known conditions/concerns. These findings support the validity and multidimensionality of early ASD risk constructs, as well as the potential use of the FYIv3.1 for phenotypic subtyping in the general population, and early detection in a broader age range of 6–16 months in future clinical studies.

Abstract
Background Imitation skills play a crucial role in social cognitive development from early childhood. Many studies have shown a deficit in imitation skills in children with autism spectrum disorders (ASD). Little is known about the development of imitation behaviors in children with ASD. This study aims to measure the trajectories of early imitation skills in preschoolers with ASD and how these skills impact other areas of early development. Methods For this purpose, we assessed imitation, language, and cognition skills in 177 children with ASD and 43 typically developing children (TD) aged 2 to 5 years old, 126 of which were followed longitudinally, yielding a total of 396 time points. Results Our results confirmed the presence of an early imitation deficit in toddlers with ASD compared to TD children. The study of the trajectories showed that these difficulties were marked at the age of 2 years and gradually decreased until the age of 5 years old. Imitation skills were strongly linked with cognitive and language skills and level of symptoms in our ASD group at baseline. Moreover, the imitation skills at baseline were predictive of the language gains a year later in our ASD group. Using a data-driven clustering method, we delineated different developmental trajectories of imitation skills within the ASD group. Conclusions The clinical implications of the findings are discussed, particularly the impact of an early imitation deficit on other areas of competence of the young child.

Abstract
The aim of this paper is to provide information regarding diversity in speech and language profiles of individuals with Autism Spectrum Disorders (ASD) and try to classify these profiles according to the combination of the communication difficulties. Research findings confirm the existence of heterogeneity of communication challenges in ASD across the lifespan. A lot of children with ASD experience communication challenges and strengths across all language sub-systems including pragmatics, grammar, semantics, syntax, phonology, and morphology in both oral and written language, while some children with autism demonstrate exceptional language abilities incl. linguistic creativity. Communication issues vary on a continuum of severity so that some children may be verbal, whereas others remain non-verbal or minimally-verbal. The diversity of profiles in speech and language development stem from either the presence of comorbid factors, as a core symptom of autistic behavior without comorbidity or both, with the development of complex clinical symptoms. Difficulties with the semantic aspect of language affect the individual's skills in abstract thinking, multiple meanings of words, concept categorization, and so on. Finally, the coexistence of ASD with other communication difficulties such as a Language Disorder, Apraxia of Speech, Speech Sound Disorders or/and other neurodevelopmental disorders raises the need for examining more carefully the emergence of new clinical profiles and clinical markers useful in performing differential diagnosis and different intervention.

Abstract
More than half of children who have autism spectrum disorder (ASD) suffer from motor impairment. In a retrospective study, the authors investigated the effect of a body-mediated workshop with dance movement therapy (DMT) on the motor skills and social skills of children with ASD by comparing 10 autistic children aged 7 to 10 years who benefited from DMT with 10 autistic children in a control group. Scores on the Movement Assessment Battery for Children and the Vineland Adaptive Behavior Scale were compared. The body-mediated workshop had significant benefits for motricity, especially manual dexterity, and for relational skills. A body-mediated workshop may have a multimodal effect and requires transmodal training. Regarding the mechanisms that explain the benefits and the cascading effect, the roles of imitation and multimodal connections are important.

Abstract
BACKGROUND Preschool children with autism in southern Sweden participated in a comprehensive Naturalistic Developmental Behavioral Intervention (NDBI) program. AIMS To evaluate the ongoing NDBI program by comparing the pre- and postintervention outcomes in terms of improved autism symptom severity. METHOD The improvement of Autism Diagnostic Observation Schedule (ADOS-R) test results between baseline and evaluation among children participating in the NDBI program (n = 67) was compared with the results among children receiving community treatment as usual (n = 27) using analysis of covariance. RESULTS The study showed that children in the NDBI group improved their ADOS-R total scores between baseline and evaluation (-0.8 scores per year; 95% CI [-1.2, -0.4]), whereas no improvement was detected in the comparison group (+0.1 scores per year; 95% CI [-0.7, +0.9]). The change in the NDBI group versus the change in the comparison group was statistically significant after adjusting for possible confounders as well. Children in the NDBI group also significantly improved their ADOS severity scores, but the scores were not significantly different from those of the comparison group. CONCLUSIONS The results from the current naturalistic study must be interpreted cautiously, but they do support earlier studies reporting on improvement of autism symptoms after early intensive interventions. Results from observational studies are difficult to interpret, but it is nevertheless of uttermost importance to evaluate costly autism intervention programs. The results do indicate that children with autism benefit from participating in early comprehensive intensive programs.

Abstract
Imitation is a pivotal skill for children with and without disabilities, serving both learning and social interaction functions for young children. Children with autism spectrum disorder (ASD) frequently experience delays in acquiring this skillset, demonstrating challenges in the ability and/or propensity to imitate the actions of others. Current intervention programs frequently use discrete trial teaching (DTT) or contingent imitation to support imitation development in young children with ASD. This study combined contingent imitation with DTT to teach imitation to individuals who had previously struggled with acquiring this skill. A multiple probe design across three preschool children with ASD was conducted within participants' early learning classrooms. Response to intervention varied across participants, with participants with more advanced imitation skills at study onset demonstrating greater outcomes. Combining contingent imitation with DTT may facilitate the propensity to imitate for individuals who exhibit some appropriate object engagement and are inconsistently imitating others' actions with objects. However, further research using stronger research design is needed to improve the teaching of imitation to young children with ASD who exhibit challenges with this skillset.

Abstract
This article extends Dr. Bob Remington's call for collaborations between those supporting behavioral approaches and those supporting more natural developmental approaches to beginning communication intervention. This article expands areas previously discussed by Dr. Remington. Topics that are addressed include pivotal behaviors that may facilitate communication acquisition, matching law and response efficiency, generalization, maintenance, and the related topics of general case instruction (which involves an understanding of stimulus and response classes). These topics reflect contemporary areas of research that could be better integrated into translational research and have not been extensively integrated into augmentative and alternative communication (AAC) practice. Dr. Remington's article discussed the value of behavioral approaches and corresponding methodology to AAC researchers and practitioners. We agree and discuss the need for greater interaction among proponents of varying approaches to intervention.

Abstract
Autism spectrum disorder (ASD) is a neurodevelopmental disorder with a behavioral phenotype characterized by impaired development of social-communicative skills and excessive repetitive and stereotyped behaviors. Despite high phenotypic heterogeneity in ASD, a meaningful subpopulation of children with ASD (∼90%) show significant general motor impairment. More focused studies on the nature of motor impairment in ASD reveal that children with ASD are particularly impaired on tasks such as ball catching and motor imitation that require efficient visual-motor integration (VMI). Motor computational approaches also provide evidence for VMI impairment showing that children with ASD form internal sensorimotor representations that bias proprioceptive over visual feedback. Impaired integration of visual information to form internal representations of others' and the external world may explain observed impairments on VMI tasks and motor imitation of others. Motor imitation is crucial for acquiring both social and motor skills, and impaired imitation skill may contribute to the observed core behavioral phenotype of ASD. The current review examines evidence supporting VMI impairment as a core feature of ASD that may contribute to both impaired motor imitation and social-communicative skill development. We propose that understanding the neurobiological mechanisms underlying VMI impairment in ASD may be key to discovery of therapeutics to address disability in children and adults with ASD.

Abstract
LAY ABSTRACT Back-and-forth interaction, or turn taking, may support later joint attention, a more complex form of interaction, when promoted in interventions for young children with autism, especially depending on the child's intent when interacting. In the present study, we observed videos of 20 toddlers with autism engaging in turn taking with their caregivers during an intervention designed to support children's joint attention. We sought to identify when the children displayed turn taking socially and when they were using it for nonsocial purposes in the intervention videos. We also observed videos after the intervention was complete to identify when children used joint attention when interacting with their caregivers. After these observations, we used these video data to explore the relationship of social turn taking to joint attention, and the relationship of nonsocial turn taking to joint attention. We found a significant relationship between social turn taking and joint attention, but not between nonsocial turn taking and joint attention. These findings support the importance of considering social turn taking in interactions between young children with autism and their caregivers.

Abstract
LAY ABSTRACT One behaviour often observed in individuals with autism is that they tend to look less towards social stimuli relative to neurotypical individuals. For instance, many eye-tracking studies have shown that individuals with autism will look less towards people and more towards objects in scenes. However, we currently know very little about how these behaviours change over time. Tracking these moment-to-moment changes in looking behaviour in individuals with autism can more clearly illustrate how they respond to social stimuli. In this study, adults with and without autism were presented with displays of social and non-social stimuli, while looking behaviours were measured by eye-tracking. We found large differences in how the two groups looked towards social stimuli over time. Neurotypical individuals initially showed a high probability of looking towards social stimuli, then a decline in probability, and a subsequent increase in probability after prolonged viewing. By contrast, individuals with autism showed an initial increase in probability, followed by a continuous decline in probability that did not recover. This pattern of results may indicate that individuals with autism exhibit reduced responsivity to the reward value of social stimuli. Moreover, our data suggest that exploring the temporal nature of gaze behaviours can lead to more precise explanatory theories of attention in autism.

Abstract
The conclusions on prosodic pitch features in autism spectrum disorders (ASD) have primarily been derived from studies in non-tonal language speakers. This cross-linguistic study evaluated the performance of imitating Cantonese lexical tones and their non-linguistic (nonspeech) counterparts by Cantonese- and Mandarin-speaking children with and without ASD. Acoustic analyses showed that, compared with typically developing peers, children with ASD exhibited increased pitch variations when imitating lexical tones, while performed similarly when imitating the nonspeech counterparts. Furthermore, Mandarin-speaking children with ASD failed to exploit the phonological knowledge of segments to improve the imitation accuracy of non-native lexical tones. These findings help clarify the speech-specific pitch processing atypicality and phonological processing deficit in tone-language-speaking children with ASD.

Abstract
Patients with Autism Spectrum Disorder (ASD) need to be provided with behavioral, psychological, educational, or skill-building interventions as early as possible. Cognitive Behavior Therapy has proven useful to manage such problems. There is also growing evidence on the usefulness of Virtual Reality Therapy (VRT) in treating various functional deficits in ASD. This exploratory study is aimed at assessing the changes in cognitive functions in children with ASD, and the putative subtending neurophysiological mechanisms, following the provision of rehab training using an innovative VRT system. Twenty patients with ASD, aged 6-15 years, were provided with 24 sessions of VRT by using the pediatric module of the BTS NIRVANA System. Neuropsychological and EEG evaluations were carried out before and at the end of the training. After VRT, all patients showed a significant improvement in their cognitive-behavioral problems concerning attention processes, visuospatial cognition, and anxiety. These findings were paralleled by an evident reshape of frontoparietal connectivity in the alpha and theta frequency range. Our study suggests that VRT could be a useful and promising tool to improve ASD neurorehabilitation outcomes. This improvement is likely to occur through changes in frontoparietal network connectivity following VRT.

Abstract
Background Adults and adolescents with autism spectrum disorders show greater difficulties comprehending speech in the presence of noise. Moreover, while neurotypical adults use visual cues on the mouth to help them understand speech in background noise, differences in attention to human faces in autism may affect use of these visual cues. No work has yet examined these skills in toddlers with ASD, despite the fact that they are frequently faced with noisy, multitalker environments. Methods Children aged 2-5 years, both with and without autism spectrum disorder (ASD), saw pairs of images in a preferential looking study and were instructed to look at one of the two objects. Sentences were presented in the presence of quiet or another background talker (noise). On half of the trials, the face of the target person speaking was presented, while half had no face present. Growth-curve modeling was used to examine the time course of children’s looking to the appropriate vs. opposite image. Results Noise impaired performance for both children with ASD and their age- and language-matched peers. When there was no face present on the screen, the effect of noise was generally similar across groups with and without ASD. But when the face was present, the noise had a more detrimental effect on children with ASD than their language-matched peers, suggesting neurotypical children were better able to use visual cues on the speaker’s face to aid performance. Moreover, those children with ASD who attended more to the speaker’s face showed better listening performance in the presence of noise. Conclusions Young children both with and without ASD show poorer performance comprehending speech in the presence of another talker than in quiet. However, results suggest that neurotypical children may be better able to make use of face cues to partially counteract the effects of noise. Children with ASD varied in their use of face cues, but those children who spent more time attending to the face of the target speaker appeared less disadvantaged by the presence of background noise, indicating a potential path for future interventions.

Abstract
BACKGROUND AND AIMS Play is used by practitioners from across disciplinary backgrounds as a natural and enjoyable context for providing intervention and support in early childhood. In the case of autism interventions, many therapies are based on the association between social play and the development of social skills, language development, and communication skills, as these are often particular areas of challenge for autistic children. However, play is a wide-ranging concept and the extant literature on play-based interventions is large and heterogeneous. This means it is challenging for practitioners and families to navigate the evidence base and make choices about differing intervention strategies. This review aims to provide a comprehensive map of the research on this topic and to develop a conceptual framework to inform clinical decision-making. METHODS An initial stakeholder consultation confirmed the relevance of the topic to practitioners and autistic people. A scoping review methodology (preregistered) was used to identify relevant literature. We systematically searched seven databases to find peer-reviewed primary intervention studies of play-based approaches targeting language, social and communication outcomes for autistic children aged 2-8 years. We then summarised the literature using narrative synthesis and Evidence Gap Maps (EGMs). The literature was summarised according to a range of characteristics, including study design, population characteristics, agent of intervention and outcomes measured, among others. These summaries were then used to develop a framework for some key considerations for practitioners appraising play-based approaches. RESULTS 388 studies met inclusion criteria. Approximately 21% of studies were RCTs, and over 50% had ≤10 participants. Over 45% of studies reported multiple relevant outcomes, with social play skills being the most common single intervention target. Girls and minority background groups are under-represented. A range of intervention types were identified, and some high-level categorisations are proposed.Main contribution: On the basis of the evidence synthesis we suggest important dimensions for appraisal of play-based interventions, including the role of play within an intervention (as a context, a key developmental mechanism, or a component of a larger approach), the underpinning philosophy (e.g. behaviourist or developmental), and the role of the practitioner (providing parent feedback, 1:1 intervention, group facilitation). CONCLUSIONS The wide range of approaches uncovered by this review is a testament to the wonderful diversity inherent to both play and autism. However, research could usefully focus on consolidating the evidence base for existing approaches, rather than aiming for further diversification. Implications: The conceptual framework proposed in this review can help practitioners appraise the literature and aid their advice to families when making shared intervention decisions.

Abstract
OBJECTIVES The Developmental Profile of Social Communication (DPSC) is based on the communication and language development in children with social communication difficulties. DPSC facilitates understanding of the challenges these children face in social interaction, communication, and linguistic development. It utilizes clinician and parent responses to build the developmental profiles of individuals. The profile allows clinicians to determine the therapeutic goals for improved cooperation and communication in various contexts. In addition, it provides insight into the parents' perspective. The aim of this study is to present the preliminary results of the DPSC in typically developing Greek children. METHODS The DPSC, a 112-item questionnaire, was administered to 357 parents of typically developing children aged 2-7.5 years using a 3-scale rating of answers. It was applied electronically via Google forms, and parents were able to ask for clarification on questions. All answers were categorized and then analyzed under independent variables. RESULTS Descriptive and hypothesis testing were used to summarize participant characteristics and performance. Findings suggest that children >7.5 years tended to develop most of the rated skills of DPSC adequately. CONCLUSIONS It was determined that the DPSC questionnaire is an easily administered tool that enables the evaluation of the social communication abilities of children of different ages.

Abstract
Este artigo tem como objetivo investigar a relação entre autismo e memória, tomando como referência as teses do filósofo francês Henri Bergson, em interlocução com o paradigma cognitivista e o campo das neurociências. A partir da perspectiva bergsoniana, defendemos haver no autismo uma dissociação precoce entre memória e ação corporal, levando à dificuldade em usar as experiências passadas para iluminar a situação atual. A memória autista, sem a bússola pragmática, vaga sem função precisa, resultando ora na incapacidade do sujeito em se localizar nos contextos e em sua própria história, ora em prodígios mnêmicos pouco úteis para a autonomia e a vida social. O autismo pode, portanto, ser entendido como transtorno da memória pragmática ou perturbação da atenção à vida, afetando a capacidade dos indivíduos de responder criativamente aos obstáculos do cotidiano.

Abstract
The recent Translations article by Bishop et al.1 draws much-needed attention to social communication (SC) in autism spectrum disorder (ASD) and to the need in autism research for treatment-sensitive measures of this key domain. In this context, the authors define SC ability as "the appropriate use and modulation of verbal and nonverbal behaviors during interactions with others"1(p. 555). "Appropriate" is defined relative to normative behaviors for developmental age and language level based on parent report. This stirred us to share our concern that clinicians, too, need ways to assess SC. Historically, observation of a patient's SC has not been part of the routine psychiatric mental status examination (MSE); clinicians lack even a common basic vocabulary for describing this vital domain. The DSM-52 does not explicitly define SC or distinguish it from social interaction (SI) or language, important terms also used in the criteria for ASD. All three terms are used interchangeably and inconsistently across the literature. Here we offer a definition of SC, distinguish it from SI and language, and propose a schema, or conceptual model, for observing and documenting an impression of a patient's SC.

Abstract
The relationship between turn taking (i.e., back-and-forth preverbal communicative exchanges) and joint attention has not been studied in interactions between children with autism and caregivers. In joint attention, a form of preverbal social communication, young children socially share attention with a partner about objects, a competency that is difficult for toddlers with autism. Video data of interactions between caregivers and 61 toddlers with autism who received joint attention-focused intervention were analyzed to determine associations between turn taking and joint attention. Results indicate a positive relationship between the two forms of social communication. Further study is needed to determine the extent to which turn taking may play a foundational role in supporting joint attention development for toddlers with autism.

Abstract
Approximately one-fourth of autism spectrum disorder (ASD) cases are associated with a disruptive genetic variant. Many of these ASD genotypes have been described previously, and are characterized by unique constellations of medical, psychiatric, developmental, and behavioral features. Development of precision medicine care for affected individuals has been challenging due to the phenotypic heterogeneity that exists even within each genetic subtype. In the present study, we identify developmental milestones that predict cognitive and adaptive outcomes for five of the most common ASD genotypes. Sixty-five youth with a known pathogenic variant involving ADNP, CHD8, DYRK1A, GRIN2B, or SCN2A genes participated in cognitive and adaptive testing. Exploratory linear regressions were used to identify developmental milestones that predicted cognitive and adaptive outcomes within each gene group. We hypothesized that the earliest and most predictive milestones would vary across gene groups, but would be consistent across outcomes within each genetic subtype. Within the ADNP group, age of walking predicted cognitive outcomes, while age of first words predicted adaptive behaviors. Age of phrases predicted adaptive functioning in the CHD8 group, but cognitive outcomes were not clearly associated with early developmental milestones. Verbal milestones were the strongest predictors of cognitive and adaptive outcomes for individuals with mutations to DYRK1A, GRIN2B, or SCN2A. These trends inform decisions about treatment planning and long-term expectations for affected individuals, and they add to the growing body of research linking molecular genetic function to brain development and phenotypic outcomes. LAY SUMMARY: Researchers have found many genetic causes of autism including mutations to ADNP, CHD8, DYRK1A, GRIN2B, and SCN2A genes. We found that each genetic cause had different early developmental milestones that explained the overall functioning of the children when they were older. Depending on the genetic cause, the age that a child first starts walking and/or talking may help to better understand and support a child's development who has a mutation to one of the above genes.

Importance of body representations in social-cognitive development: New insights from infant brain science. PROGRESS IN BRAIN RESEARCH 2020; 254:25-48.

Abstract
There is significant interest in the ways the human body, both one's own and that of others, is represented in the human brain. In this chapter we focus on body representations in infancy and synthesize relevant findings from both infant cognitive neuroscience and behavioral experiments. We review six experiments in infant neuroscience that have used novel EEG and MEG methods to explore infant neural body maps. We then consider results from behavioral studies of social imitation and examine what they contribute to our understanding of infant body representations at a psychological level. Finally, we interweave both neuroscience and behavioral lines of research to ground new theoretical claims about early infant social cognition. We propose, based on the evidence, that young infants can represent the bodily acts of others and their own bodily acts in commensurate terms. Infants initially recognize correspondences between self and other-they perceive that others are "like me" in terms of bodies and bodily actions. This capacity for registering and using self-other equivalence mappings has far-reaching implications for mechanisms of developmental change. Infants can learn about the affordances and powers of their own body by watching adults' actions and their causal consequences. Reciprocally, infants can enrich their understanding of other people's internal states by taking into account the way they themselves feel when they perform similar acts. The faces, bodies, and matching actions of people are imbued with unique meaning because they can be mapped to the infant's own body and behavior.

Abstract
Behavioral studies indicate that autistic traits predict reduced gaze toward social stimuli. Moreover, experiments that require participants to make an explicit choice between stimuli indicate reduced preferences for social stimuli in individuals with high autistic traits. These observations, in combination, fit with the idea that gaze is actively involved in the formation of choices-gaze toward a stimulus increases the likelihood of its subsequent selection. Although these aspects of gaze and choice behavior have been well characterized separately, it remains unclear how autistic traits affect the relationship between gaze and socially relevant choices. In a choice-based eye-tracking paradigm, we observed that autistic traits predict less frequent and delayed selection of social stimuli. Critically, eye tracking revealed novel phenomena underlying these choice behaviors: first, the relationship between gaze and choice behavior was weaker in individuals with high autistic traits-an increase in gaze to a stimulus was associated with a smaller increase in choice probability. Second, time-series analyses revealed that gaze became predictive of choice behaviors at longer latencies in observers with high autistic traits. This dissociation between gaze and choice in individuals with high autistic traits may reflect wider atypicalities in value coding. Such atypicalities may predict the development of atypical social behaviors associated with the autism phenotype. LAY SUMMARY: When presented with multiple stimuli to choose from, we tend to look more toward the stimuli we later choose. Here, we found that this relationship between looking and choosing was reduced in individuals with high autistic traits. These data indicate that autistic traits may be associated with atypical processing of value, which may contribute to the reduced preferences for social stimuli exhibited by individuals with autism.

Abstract
Purpose
This paper aims to present the application and critical reflection on the effects of a intervention for children with autism spectrum disorder (ASD): the Soundbeam Imitation Intervention (SII). The intervention is based on the imitation of meaningless body gestures supported by a musical feedback. The rationale underlying SII is that mirror neurons deficit may represent the cause for the incomplete development of social and motor functioning in children with ASD. Following this assumption, it is possible to hypothesise that a systematic activation of this a system through the simultaneous observation-execution of meaningless body gestures may affect functional changes of mirror-related functions.
Design/methodology/approach
A sample of 14 children, who were between 5 and 9 years of age, with a diagnosis of ASD were involved in a six weeks’ SII programme. The programme is designed as a three-step progression, where each step includes exercises that focus on an activity: synchronous/one arm imitation, synchronous/two arms imitation and delayed imitation. Exercises are based on repeated movements-melodies associations of increasing difficulty. Motor imitation and social attention were assessed using a synchronous video-modelling task pre and post intervention.
Findings
Data highlight significant improvements in imitation accuracy and duration of social sustained attention were achieved.
Originality/value
Data reported in this paper provide preliminary and promising evidence that imitation and social attention skills acquired through SII can be generalised to a video-modelling imitation setting. The SII ordinal execution has included meaningless gestures, usually excluded from previous interventions, and this adds further validity to the training.

Abstract
Young children with autism spectrum disorder (ASD) present with a broad range of spoken language abilities, as well as delays in precursor skills such as gesture production and joint attention skills. While standardized assessments describe language strengths, the Communication and Symbolic Behavior Scales (CSBS-DP) is a particularly robust measure as it additionally characterizes precise aspects of social communication. This study provides a unique contribution by assessing the interactional effects of CSBS-DP Social Composite performance with early language samples on later language outcomes. Our results indicate that multiple social communication elements significantly interact with early spoken language to predict later language. Our findings also highlight the transactional relationship between early spoken vocabulary and social communication skills that bolster language development growth.

Abstract
Autism spectrum disorder (ASD) is characterized by deficits in social communication and interaction and the presence of restricted and repetitive patterns of behavior and interests. Currently, ASD affects 1 in 59 individuals and can be a costly disorder across one's lifetime. Because of the prevalence, costs, and range of behavioral needs, early intervention is vital to teach skills across a variety of domains and prevent the development or exacerbation of behavioral deficits and excesses. Interventions based on applied behavior analysis have the most empirical support; several strategies to teach social skills, communication, and adaptive skills are discussed.

Changes in Developmental Trajectories of Preschool Children with Autism Spectrum Disorder during Parental Based Intensive Intervention. Brain Sci 2020; 10:brainsci10050289.

Abstract
Background: Research highlights the positive effects of early intensive intervention with parent and school involvement for preschool children with Autism Spectrum Disorder (ASD) on general developmental outcomes and social skills in randomized controlled trials. However, given the inter-individual variability in the response to treatment, it is necessary to investigate intervention effects in terms of mediators and moderators in order to explain variability and to highlight mechanisms of change. Methods: 25 children in the experimental group were exposed to early intensive intervention and 14 children in the control group were subjected to “as usual” intervention. The initial assessment was obtained at the time of diagnosis (T1) and the follow-up assessment was conducted after 15 months of intervention (T2) in both groups. Results: Participants in the experimental group achieved more prominent gains in both cognitive and socio-interactive skills. The role of specific factors able to predict general quotient and language quotient after intervention were investigated, pointing out the contribution of personal–social and performance abilities. Conclusions: The findings support the importance of parental involvement in targeting ASD core symptoms. Further, results informed our understanding of early predictors in order to identify specific elements to be targeted in the individualized intervention design.
