Abstract Background: This study examined the social synchronization in children with autism spectrum disorder (ASD) when responding to others’ joint attention. Social synchronization refers to an individuals’ temporal coordination during social interactions, which has been found to play a crucial role in social development. Deficient joint attention has been repeatedly found in individuals with autism spectrum disorder, and previous studies have demonstrated various explanations about it. In a more recent perspective, joint attention could be associated with spontaneous social motor synchronization, and it is possible to explore social synchronization as a pathway to understanding the impairments of joint attention in children with ASD.Methods: Forty-one children aged 5 to 8 with ASD and 43 age-matched typically developing (TD) children watched a video to completed the response to joint attention (RJA) tasks, during which their gaze data were collected. The synchronization of gaze-shift behaviors between children and the female model in the video was measured with the cross-recurrence quantification analysis (CRQA). Results: We found that children with ASD had the ability, to some extent, to synchronize their gaze shifts with the female model in the video during RJA tasks. However, compared to the TD children, children with ASD displayed lower levels of synchronization and longer latency in this synchronized behavior. Limitations: The RJA task in our study was not a real social interaction task but rather a one-way interaction. Social interaction between two persons through live video or a natural scenario should be further explored. Besides, additional work is necessary to determine whether our findings generalize to individuals across the full autism spectrum. Conclusion: These findings provide a new avenue to deepen our understanding of the impairments of joint attention in children with ASD. Notably, the analytic method can be further applied to explore the social synchronization of numerous other social interactive behaviors in ASD. Additionally, the impairment of social synchronization may be a new implicit indicator for the evaluation of autism and can be utilized to screen children with ASD along with other indicators.

AbstractThere had been a long way to go before we felt comfortable about even discussing the issues revolving around the concept of ‘schizophrenia’, let alone reckoning on mere semantic revision. In this editorial, we aim to extend our discussion on the reasons behind the slow death of the concept of ‘schizophrenia’ and the benefits of changing the name and embracing a spectrum approach with an umbrella psychosis spectrum disorder (PSD) category (similar to autism spectrum disorder) that goes further than a mere semantic revision. We attempted to cover the topic of the renaming by providing five most pertinent points categorised under five domains: reasons, signals, challenges, promises and steps for the change. Admittedly, even a modest revision, such as classifying all psychotic disorder categories under an umbrella category of PSD, and abolishing the term schizophrenia requires careful deliberation and some effort in the beginning, but the revision is well worth the effort considering the benefits in the long run. Renaming a particular form of mental suffering should be accompanied by a broader debate of the entire diagnosis-evidence-based-practice (EBP)-symptom-reduction model as the normative factor driving the content and organisation of mental health services that may be detached from patients’ needs and reality, overlooks the trans-syndromal structure of mental difficulties, appraises the significance of the technical features over the relational and ritual components of care, and underestimates the lack of EBP group-to-individual generalisability. Individuals may make great strides in attaining well-being by accommodating to living with mental vulnerabilities through building resilience in the social and existential domains. Changing the name and the concept of ‘schizophrenia’, which goes beyond a mere semantic revision, may become the first step that allows catalysation of the process of modernising psychiatric science and services worldwide.

Purpose Most children with autism spectrum disorder (ASD) have below-age lexical knowledge and lexical representation. Our goal is to examine ways in which difficulties with social communication and language processing that are often associated with ASD may constrain these children's abilities to learn new words and to explore whether minimizing the social communication and processing demands of the learning situation can lead to successful learning. Method In this narrative review of recent work on lexical development in ASD, we describe key findings on children's acquisition of nouns, pronouns, and verbs and outline our research program currently in progress aimed at further elucidating these issues. Conclusion Our review of studies that examine lexical development in children with ASD suggests that innovative intervention approaches that take into account both the social communication and processing demands of the learning situation may be particularly beneficial.

The etiology of autism spectrum disorder (ASD) is multifactorial, complex, and likely involves interactions among genetic, epigenetic, and environmental factors. With respect to environmental influences, a growing literature implicates intrauterine experiences in the origin of this pervasive developmental disorder. In this prospective longitudinal study, we examined the hypothesis that fetal exposure to maternal cortisol may confer ASD risk. In addition, because ASD is four times more prevalent in males than in females, and because sexually dimorphic responses to intrauterine experiences are commonly observed, we examined whether or not any associations differ by fetal sex. Maternal plasma cortisol was measured at 15, 19, 25, 31, and 37 weeks’ gestation in a sample of 84 pregnant women. ASD symptoms were assessed in their 5-year-old children with the Social Communication Questionnaire (SCQ). Fetal exposure to lower levels of maternal cortisol was associated with higher levels of ASD symptoms only among boys. The observed hypocortisolemic profile exhibited by these mothers may indicate a risk factor that precedes the stress of caregiving for a child with ASD and may not be solely a consequence of the stress of caregiving, as previously thought. These findings confirm the value of examining prenatal hormone exposures as predictors of ASD risk and support the premise that altered prenatal steroid exposures may play a role in the etiology of ASD.

Problem Statistics indicate that Autism Spectrum Disorder (ASD) is on the increase in America and worldwide (Xu, Strathearn, Liu, & Bao, 2018; Baio et al., 2018). Autism spectrum disorder can impair an individual’s ability to engage in neurotypical behavior, which has the potential to increase their vulnerability to being shunned and bullied. This makes autism a major societal concern with significant costs to the individual, their family, private/public health insurance, state financial aid programs, and to the nation. This present study was undertaken to determine, in the opinions of those connected to the case, whether the interventions engaged in this case were effective and to what extent the educational and social interventions practiced in this specific case were responsible for enabling Carter to reach the place where the diagnosticians felt that he no longer met the criteria for receiving services for autism spectrum disorder. Purpose The purpose of this study was to identify social and educational interventions used in Carter's journey with Autism Spectrum Disorder and to document the social and educational interventions employed by several individuals who worked with him. Further, the study sought to describe the impact of these interventions on Carter, from the perspectives of the key individuals involved in the early education of the child. Additionally, the study set out to determine whether these interventions actually enabled Carter to no longer meet the criteria for receiving services for autism spectrum disorder. -- Method The study employed a qualitative case study approach which gathered data mainly through semi-structured interviews and focus groups. Other data sources included Carter’s mother's (Meghan's) account of her experience, key documents, and examples of learning activities found to be of benefit to the child. The nine individuals who were interviewed were invited to participate because they had been directly involved with the case. The data was analyzed using NVivo data analysis. Results The results from the analysis of the data study indicate that there was a positive relationship between the interventions reported and Carter's no longer meeting the criteria for services for ASD. The activities reported proved to be too numerous to be mentioned individually and were therefore grouped thematically. The two large groups were the social interventions and the educational interventions. The social interventions group was comprised of activities, such as Gymfants (gymnastics for young children), Children’s Choir, Adventurers Club, and attending regular school which promoted social interactions. These groups facilitated Carter’s working with others, taking directions from others, imitating others, leading, following, and taking turns. Language was key to these interactions. Educational interventions included; reading, attending homeschool, regular school, strategic games such as Connect Four, Uno, and geographical puzzles, floor puzzles; foreign language videos and science videos among other activities. These interventions incorporated language and encouraged Carter in individual work, seated work, pattern identification, and viewing for a purpose among other things. These interventions were planned by Meghan outside of the Individualized Educational Plan (IEP) and in addition to Speech Therapy. Conclusions As a result of this study, the reader can see that the curriculum developed for Carter by Meghan was directly related to his progress. The study concluded that Carter's family working together to provide the program of interventions contributed greatly to his no longer meeting the criteria to remain in the autism therapy program designed for him by the Individualized Educational Plan (IEP) team. It appeared that the intentionality of Carter’s support team had a significant relationship with his progress. It was also concluded that there was a strong relationship between Music as a theme and Carter's progress. The study concluded that the combination of educational and social interventions employed with Carter helped to eliminate the need for him to receive services for autism spectrum disorder. The study showed that intervention in autism requires parental involvement as the delivery of a variety of social and educational interventions through the medium of the home allowed for a natural, meaningful and permanent transfer of knowledge and growth in a number of areas. It is therefore obligatory that the parent/therapist/school partnership be supported and empowered.
