Language ability has been associated with emotion regulation (ER) ability. Children on the autism spectrum have greater rates of language delays and lower ER ability. Despite this, autism traits have not been considered or controlled for in past research. This study therefore examined the association between language ability and ER in young…

Background: Understanding how or whether sedentary behavior affects motor competence in young children is important considering that children spend a lot of time sedentary. The aim of this study was to examine whether sedentary behavior predicts motor competence in young children. Methods: A longitudinal study with a total of 372 children aged 3.5…

This investigation examined whether the mode of locomotion matters in how 8-, 10-, 12-, and 14-year-old children (N = 91) judge dynamic affordances in a complex perception-action task with significant safety risks. The primarily European American children in the sample came from the area of Iowa City, Iowa and were balanced for gender. The same…

This study examined connections between parental quality of life (QoL) and features of children (autism severity, cognitive ability, behavioral profile, and sociodemographic factors). Parents of 97 children attending an autism-specific preschool completed the Quality of Life in Autism, Vineland Adaptive Behavior Scales and Child Behavior…

Purpose: To explore whether parental perceptions of risk and attitudes toward risk-taking during play are associated with preschoolers' physical activity (PA) and physical literacy (PL). Methods: Nova Scotia preschoolers (35 boys, 17 girls; mean age = 3.8 years, range = 3-5 years) and parents (n=52 pairs) provided data. Linear regressions assessed…

Play and playfulness have a key role in children's development. Not enough is known about the playfulness of children with autism spectrum disorder (ASD) and its relationship to children's behavioural problems, as well as the role of caregiver behaviours during play in this relationship. The present study examines the moderating role of teachers'…

Although the early behaviors associated with autism spectrum disorder have been well characterized, many behaviors are also commonly observed in young children with other developmental delays and even in those with typical development. Therefore, consideration must be given to whether a child demonstrates sufficient autism spectrum disorder…

Atypical sensory response patterns are common in children with autism and developmental delay. Expanding on previous work, this observational electroencephalogram study assessed auditory event-related potentials and their associations with clinically evaluated sensory response patterns in children with autism spectrum disorder (n = 28),…

Purpose of this quasi-experimental trial was to investigate the effect of Pivotal response treatment (PRT) versus treatment as usual (TAU) on autism symptoms. Children with autism spectrum disorder (ASD), aged 3-8 years, received either PRT (n = 11) or TAU (n = 13). Primary outcome measure was the total score on the Autism Diagnostic Observation…

Children with autism spectrum disorder (ASD) tend to receive several related services during their early school years. In this study, we followed 70 preschoolers with ASD and used parent reports to document the intensity of these services over a 4-year period, in relation to children's outcomes in three domains. While behavioral difficulties…

The field of early autism research is in dire need of outcome measures that adequately reflect subtle changes in core autistic behaviors. This article compares the ability of a newly developed measure, the Brief Observation of Social Communication Change (BOSCC), and the Autism Diagnostic Observation Schedule (ADOS) to detect changes in core…

Cross-informant ratings of are considered gold standard for child behavioral assessment. To date, little work has examined informant ratings of adaptive functioning for youth with autism spectrum disorder (ASD). In a large, diverse sample of youth with ASD, this study evaluated parent-teacher concordance of ratings of adaptive functioning and…

Background: Sleep affects children's cognitive development, preparedness for school and future academic outcomes. People with Down syndrome (DS) are particularly at risk for sleep-disordered breathing (SDB). To our knowledge, the association between SDB and cognition in preschoolers with DS is unknown. Methods: We assessed sleep by using…

Background: Marshall-Smith syndrome (MSS) is an infrequently described entity characterised by failure to thrive, developmental delay, abnormal bone maturation and a characteristic face. In studying the physical features of a group of patients, we noticed unusual behavioural traits. This urged us to study cognition, behavioural phenotype and…

This article addresses how kinesiological research on children should advance. Using the study of motor development as a backdrop, the article is divided into three sections. The first section relates the four fundamental questions in motor development that have been asked throughout its history. The second section describes four areas of…
