Fragile X syndrome (FXS), the leading heritable cause of intellectual disability, has a co-occurrence rate of autism spectrum disorder (ASD) estimated at ~60%. The onset and rates of motor development in FXS are slower relative to neurotypical development, and even more so in the context of co-occurring FXS + ASD. Extant evidence suggests these…

Knowledge of results (KR), particularly its informational role, has often been regarded as redundant for learning interception-like tasks, such as coincidence-anticipation timing tasks. However, it is possible that the KR's guiding effect might be detrimental to motor adaptation, instead of only redundant, leading to a dependency on KR and…

"Research Findings:" The influence of early childhood teachers' professional development on fundamental movement skills remains unknown in the literature. The purpose of the present study was to examine how early childhood teachers' professional development in physical education (PE) contributes to predicting children's fundamental…

This study was conducted to determine how total fundamental movement skill (FMS) score and, separately, locomotor skill (LMS), and object control skill scores in children 3-8 years old predicted their specific-intensity physical activity 3 years later. Overall, 441 Finnish children (51.7% female, baseline mean age of 5.6 years) participated in the…

Purpose: The purpose of the study was to investigate child- and intervention-level factors that predict improvements in functional communication outcomes in children with motor-based speech sound disorders. Method: Eighty-five preschool-age children with childhood apraxia of speech (n = 37) and speech motor delay (n = 48) participated.…

Developmental coordination disorder (DCD) impacts the quality of life and ability to perform coordinated actions in 5% of school-aged children. The quality of body representations of individuals with DCD has been questioned, but never assessed. We hypothesize that children with DCD have imprecise body representations in the sensory and motor…

The aim of our study is to describe the neuromotor development of preterm and low birth weight infants at 1 and 2 years of corrected age, and to examine the extent to which perinatal, neonatal, socio-demographic, and neuromotor development indices measured at the age of 1 are able to predict infants' development indices at the age of 2. Our sample…

Children with CHARGE syndrome, an extremely complex, highly variable genetic disorder, are significantly delayed in the onset of their motor milestones in comparison with children without disabilities due to sensory and motor deficits as well as lengthy hospitalizations and reduced physical activity. Currently, the role of parents' perceptions and…

Motivation is a key factor for child development, but very few studies have examined child and family predictors of both child task and perceived motivation. Thus, the three aims of this 6-month longitudinal study in preschoolers with global developmental delays (GDD) were to explore: 1) differences between task and perceived motivation in…

We investigated infant's manual motor behaviour; specifically behaviours crossing the body midline. Infants at elevated likelihood of Autism Spectrum Disorder (ASD) and/or Attention Deficit Hyperactivity Disorder (ADHD) produced fewer manual behaviours that cross the midline compared to infants with a typical likelihood of developing these…

Aim: To investigate developmental trajectories in early childhood and predictors of class assignment. Methods: Data were available for Gen2 infants at 12 (n = 2275), 24 (n = 1845) and 36 (n = 2110) months of age in the Raine Study. Latent growth class analysis was used to identify developmental trajectories based on the Ages and Stages…

Background and Aims: Individuals with fragile X syndrome (FXS) characteristically struggle with language and communication throughout the life course, but there is limited research on the development of communication before 24 months. The purpose of this study is to describe the early communication of infants and toddlers with FXS using the…

The purpose of the study was to evaluate fine- and gross-motor development and basic cognitive skills in 3-18 month-olds in relation to home factors, age and weight. Three hundred and seventy mother-child dyads were recruited. For age, two groups were analyzed: 3-11 months and 12-18 months. Motor and basic cognitive skills were assessed using the…

Purpose: This study examined the extent to which fundamental motor skill competence (FMSC; locomotor and object control skill competence) and perceived physical competence (PPC) predicted physical activity levels and sedentary behaviors during free-play time at preschool. Method: A total of 72 children (girls n = 33, boys n = 39; M[subscript age]…

Early intensive intervention has been shown to significantly affect the development of children with autism spectrum disorder. However, the costly implementation of such interventions limits their wide dissemination in the community. This study examined an integration of the Early Start Denver Model into community preschool programs for children…
