Previous studies have suggested that deafness could lead to deficits in motor skills and other body-related abilities. However, the literature regarding motor skills in deaf adults is scarce and existing studies often included participants with heterogeneous language backgrounds and deafness etiologies, thus making it difficult to delineate the…

We investigated the influence of the time-of-day and sleep on skill acquisition (i.e., skill improvement immediately after a training-session) and consolidation (i.e., skill retention after a time interval including sleep). Three groups were trained at 10 a.m. (G10[subscript am]), 3 p.m. (G3[subscript pm]), or 8 p.m. (G8[subscript pm]) on a…

Different individuals learn different solutions to the same perceptual-motor task regardless of the fact that they may undergo the same practice conditions. In the current study, we characterized individual solutions to a perceptual-motor task. Eighteen self-declared right-handed participants were requested to intercept a moving target controlling…

Children tend to make more last-minute locomotor adjustments than adults when avoiding stationary obstacles. The purpose of this study was to compare avoidance behaviors of middle-aged children (10-12 years old) with young adults during a head-on collision course with an approaching virtual pedestrian. Participants were immersed in a virtual…

Purpose: Despite known motor and spoken language impairments in autism spectrum disorder (ASD), the motor skills underlying speech production and their relationship with language skills have rarely been directly investigated in this population. Method: Thirty-nine autistic children (14 minimally verbal [MV], 25 verbal [V]) and 11 non-autistic…

Rater training is necessary to accurately evaluate fundamental motor skills among children with developmental disabilities (DD). The purpose of this pilot study was to examine the impact of an online rater training program for novice raters on scoring accuracy of the run and two-hand strike skills on the Test of Gross Motor Development-Third…

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…

Background: Autism spectrum disorder and cerebral palsy are prevalent neurodevelopmental disorders. Autistic individuals or individuals with cerebral palsy often struggle with sensory processing that further impacts movement execution. Immersive virtual reality (VR) is a promising assessment and intervention modality to promote motor learning in…

This paper examines the influence of task and skill level constraints on the generality of proximal-distal control for within-limb movement coordination. Analysis and synthesis of the experimental findings leads to the proposition that proximal-distal is one of several within-limb patterns of coordination, including: the reverse distal-proximal…

Mirror visual feedback increases neural activity, enhances performance, and induces neuroplasticity; however, mixed results have been observed during the learning of motor skills. While mirrors are commonplace in Western dance education, further research is needed to determine how mirrors are used when learning dance phrases. This study measured…

Background: Children with developmental coordination disorder (DCD) frequently have difficulties performing gross motor skills such as the overarm throw. Our study examines the differences in both qualitative and quantitative characteristics of overarm throwing for accuracy between typically developing (TD) and children with DCD. Methods: A total…

Expectancies for success and autonomy support have been shown to facilitate motor learning and enhance motor performance. The purpose of the study was to examine whether we replicated (a) enhanced expectancies and autonomy support intervention enhanced motor skill learning in children, and (b) identified the underlying psychological mechanism.…

Children with disabilities often experience gross motor delays. Adults, including parents, can play a crucial role in supporting children's motor development. However, a limited number of research studies have focused on building parents' capacity to support their young children's motor skill development. The purpose of this study was to examine…

An external focus of attention and autonomy support are identified as key factors to optimize motor learning; however, research in children is limited. Moreover, research has failed to examine these factors in ecologically valid motor learning settings, like physical education. Therefore, the present study examined the effects of external focus of…

This study examines the reliability of parental concern (PC) as an indicator for mental disorders in preschool-aged children in a clinical setting, aiming to establish sensitivity and specificity, evaluate PC's predictive value for specific diagnoses, and explore the influence of child age on predictions. The sample comprises 574 children referred…
