This study adds to the existing pool of knowledge regarding the imitative behavior of children with autism spectrum disorder (ASD). Methods: The over-imitation behaviors of preschool children with ASD were compared to age-matched typically developing (TD) children. Results: The hypothesis was that the TD children would over-imitate to a much…

Children's understanding of the stability of gender over time has long been recognized as a hallmark of early childhood cognitive development. Prior research has argued that until roughly age 6, children do not understand that a person's gender identity remains consistent if the person undergoes a change in gendered behavior or appearance.…

This study examined the sustained and moderating effects of a behavioural sleep intervention for autistic children in a randomised controlled trial. Autistic children (5-13 years) with sleep problems were randomised to the Sleeping Sound intervention or Treatment as Usual (TAU). At 12-month follow-up (n = 150), caregivers of children in the…

Feeding challenges are a significant concern for autistic children. Literature has yet to comprehensively characterize feeding challenges for autistic children. Further research is needed to understand predictors of feeding severity and identify opportunities for screening and intervention. The purpose of this study was to characterize the…

Parenting style plays an important role in children's externalizing behaviors. Differences in physiological regulation among children may lead to variations in whether or to what extent parenting style influences them. The present study aimed to investigate the effect of parenting styles on young children's development of externalizing behaviors…

According to coercion theory (Patterson, 1982, 2016), children's aggression is developed and maintained through transactional processes between parents and their children that unfold over time. The theory provides a model of the behavioral contingencies that explain how parents and children mutually "train" each other to behave in ways…

Emotion dysregulation is one of the challenges that children with autism spectrum disorder (ASD) and their families face. It is unclear whether emotion dysregulation plays a mediating role in the relationship between sensory processing patterns and problem behaviors among these children. This study examined the relations between emotion…

Purpose: The study objective was to determine if the validated Behavioral Inflexibility Scale (BIS) is sensitive to the detection of developmental changes in inflexibility in a sample of autistic children. Methods: Parents of autistic children (n = 146, 3-17 years) completed the BIS at two time points, one year apart, to examine change. Results:…

Interoception refers to the processing of internal bodily states and plays a critical role in motivational processes and behaviours. Instruments for assessing its subjective components (i.e., interoceptive sensibility) during childhood are crucially needed. Thus, in this study, we adapted and evaluated the psychometric properties of the…

This study aimed to describe the behavioral profile of individuals with SYNGAP1-ID. Parents/carers of 30 individuals aged 3-18 years old with a diagnosis of SYNGAP1-ID and 21 typically developing individuals completed the Vineland-3 Adaptive Behavior Scale and the Child Behavior Checklist. We found that those with SYNGAP1-ID showed fewer adaptive…

To explore the effects of family functioning on problem behaviour among Chinese preschool children, 1,025 preschool parents were assessed using the family assessment device, child problem behaviour scale, and parent-child relationship scale through a random sampling method. Based on the McMaster model of family functioning and the Process Person…

Disparities in socioeconomic status (SES) may affect individuals' risk preferences, which have important developmental consequences across the lifespan. Yet, previous research has shown inconsistent associations between SES and risky decision-making, and little is known about how this link develops from a young age. The current research is among…

A foundational mechanism underlying human cooperation is reciprocity. In the context of repeated interactions with others, it is not always clear the degree to which in-kind responses reflect responsiveness to partners' prior behaviors ("reactive" responses), an interest unrelated to the partner ("nonreactive" responses), or…

Secure attachment has broad and long-lasting benefits for the development and wellbeing of a child. Conversely, disorganized attachment is associated with social, emotional, and behavioral problems in children, and later psychopathology. Children with a developmental delay or disability (DD) may be at greater risk of insecure or disorganized…

In synchronous-reinforcement schedules, the duration of behavior directly controls the duration of reinforcement on a moment-to-moment basis. We replicated and extended Diaz de Villegas et al. (2020) by comparing the effects of synchronous reinforcement with two accumulated-reinforcement schedules for increasing on-task behavior for seven…
