This study quantified the spatial exploration of 13 infants born very and extremely preterm (PT) at 4 months corrected age as they learned that moving their feet vertically to cross a virtual threshold activated an infant kick-activated mobile and compared results to 15 infants born full-term (FT) from a previously published study. Spatial…

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…

This study (a) examined the associations among different performance metrics derived from different strategies (i.e., maximum and average scores) and trials from product-oriented measures of motor skills, and (b) explored how different performance metrics from product-oriented assessments of motor skills change in young children with typical…

Exploration is considered essential to infant learning, but few studies have quantified infants' task exploration. The purpose of this study was to quantify how infants explored task space with their feet while learning to activate a kick-activated mobile. Data were analyzed from fifteen 4-month-old infants who participated in a 10-min mobile task…

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…

The overhand throw is a complex whole-body motor skill that is fundamental to many sports and activities. When throwing properly, the momentum generated to complete the movement begins in the lower body and transfers through the trunk to the throwing arm. This proof-of-concept study's primary purpose was to evaluate the impact of the nonthrowing…

The motor and social skill difficulties experienced by many children with autism spectrum disorder (ASD) can create challenges when participating in age appropriate physical activity contexts. Although behavioral interventions can increase the general social communicative skills of children with ASD, often the skills targeted are not relevant to…

Background: Roberton's movement components are used to assess fundamental motor skills as segmental developmental sequences. In 1991, Haywood, Williams and VanSant determined that original developmental sequences proposed for the backswing levels of the overarm throw did not encompass all ages. Their study of older throwers identified two new…

The adoption of compensatory movement patterns occurs when limitations in mobility, stability, or motor control prevent proper motion from occurring. These dysfunctional movements may inhibit fundamental motor skill development and negatively influence perceived movement competence, impeding the development of physical literacy. Therefore, this…
