Fundamental motor skills are important markers of child development, yet gold standard measurement of these skills may be infeasible in large surveillance studies. The SUNRISE study examines movement behaviors and fundamental motor skills among an international sample of preschool-aged children. This study aimed to evaluate the associations of…

When humans encounter the same perturbation twice, they typically adapt faster the second time, a phenomenon called savings. Studies have examined savings following adaptation to a gradually introduced perturbation, with mixed results. These inconsistencies might be caused by differences in how behavior returns to its baseline state during the…

There is a common assumption that changes in developmental movement patterns (process) leads to better skill outcome performance (product); however, limited longitudinal data evaluate this assumption. This study examined (a) the longitudinal relationship among process and product motor skill scores across early childhood (3.5-6 years) and (b) the…

Based on dynamic systems theory, the longitudinal study tracked 120 kindergarten children 2 years to examine the differentiation and transition of object control profiles among preschool children aged 3 to 6. Latent profile analysis (LPA) and latent transition analysis (LTA) were employed to identify development profiles and transitions, as well…

The ability to predict upcoming events is essential in infancy because it enables babies to process information optimally and have successful goal-directed interactions with their environment. In this article, we examine how infants generate predictions in perception, cognition, and action, and address whether and how their predictions are…

Crawling is considered an important motor skill for infants. Although infants show variations in their crawling, the association between crawling variations and subsequent development is unexplored. This study investigates the difference in amount of crawling variation between infants with and without subsequent developmental delays. This…

The aim of this cross-sectional study was to compare acceleration outputs of the parkour-style "tic tac" action with those of the drop jump and the lay-up shot in youth basketball players. A total of 25 participants (17 boys, 13.80 ± 1.30 years of age; and eight girls, 15.00 ± 0.80 years of age) completed three trials of each action…

Atypical sensory perception and motor impairments are primary features of autism spectrum disorder (ASD) that indicate atypical development and predict social and non-social challenges. However, their link is poorly understood. Sensory perception is often integrated with motor processes when a sensory effect is temporally contiguous with the motor…

The present study compared the age of achievement of 10 early gross motor milestones (lift head, roll back to belly, sit without support, crawl on hands and knees, stand with assistance, stand without support, walk with assistance, walk without support, climb stairs, and walk up/downstairs without support) of 111 school-age individuals diagnosed…

Fine motor skills (FMS) have been intensely studied in developmental contexts, with little attention to their empirical structure and developmental changes. We tested the factor structure of FMS on 5- to 10 year old children in two cohorts from 2020 to 2023, beginning in kindergarten and grade 2 and followed up 1 year later (n = 240 and 310, 49.7%…

This was a cross-sectional study that aimed to evaluate the association between breastfeeding and motor development of infants at 3-4 months of age in the city of Pelotas, Rio Grande do Sul. The outcome, infant motor development, was evaluated through the Bayley Scale of Infant Development (Bayley III). The prevalence of infants that stopped…

This study examined the effect of a 12-week fundamental movement skills (FMS) intervention on the motor skills of 20 boys with autism spectrum disorder (ASD) (ages 3-10 years) in an Asian country and whether the intervention effect would persist for at least 12 weeks after the intervention. In Part I, 10 boys with ASD (Group 1) received the…

This study is a review that aimed to examine the effects of the peer teaching model implemented in physical education classes on students' motor skill development, acquisition of fundamental skills, maintenance of physical fitness, self-confidence, and cooperation. Various scientific studies conducted with students of different ages and skill…

Infant motor development is affected by the sociocultural context in which it takes place. Because societal and cultural practices are dynamic, this exploratory study examined whether the ages at which infants typically learned to crawl, cruise, and walk changed over the past 3 decades. We compiled archival data from 1,306 infants born between…

How do age and the acquisition of independent walking relate to changes in infants' everyday experiences? We used a novel ecological momentary assessment (EMA) method to gather caregiver reports of infants' restraint, body position, and object holding via text messages sparsely sampled across multiple days of home life at 10, 11, 12, and 13 months…
