Early childhood is characterized by rapid increases in both motor skills and executive function skills. Rather than simply codeveloping, the development of motor and executive function skills may be linked causally. In this article, we introduce corticomuscular coherence as a paradigm for psychologists interested in testing mechanistic questions…

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…

Background: Several studies have reported low adherence to World Health Organization sedentary behavior (SB) guidelines in the early years. The purpose of this review is to examine the associations between time spent in different types of SB (screen time and habitual SB) and motor competence (MC; fundamental motor skills, fine and gross motor…

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…

We describe the development of 236 children with Angelman syndrome (AS) using the Bayley Scales of Infant and Toddler Development, Third Edition. Multilevel linear mixed modeling approaches were used to explore differences between molecular subtypes and over time. Individuals with AS continue to make slow gains in development through at least age…

Does knowledge of other people's minds grow from concrete experience to abstract concepts? Cognitive scientists have hypothesized that infants' first-person experience, acting on their own goals, leads them to understand others' actions and goals. Indeed, classic developmental research suggests that before infants reach for objects, they do not…

An emerging body of literature suggests that early motor skills may be a key predictor of language development in children with autism spectrum disorder (ASD). However, characteristics of subject groups, targeted skill areas and their assessment tools, and methodological approaches significantly vary across existing studies. This scoping review…

This study explored the impacts of enactment and motor imagery on working memory for instructions in children with autism spectrum disorder (ASD), children with intellectual disability (ID) and typically developing (TD) children. The participants were asked to hear (hearing condition), imagine enacting (motor imagery condition) and actually enact…

The first years of life are an optimal time for developing motor competence. However, the evidence regarding motor competence in early childhood is fragmented and needs to be clearly synthesized and presented. To establish effective evidence-based decision making in research, practice, and policy for the early years, this expert statement, on…

Several studies have previously investigated the effects of sticky mittens training on reaching and grasping development. However, recent critique casted doubts on the robustness of the motor effect of this training. The current study presents a pre-registered report that aimed to generalize these effects to Swedish infants. Three-month-old…

This paper aims to show the effects of actions focused on supporting the development of children with Autistic Spectrum Disorder (ASD). Conducted with an eclectic approach, these actions sought techniques tailored to the individual person and their problems. Children aged 5-7 years underwent a two-stage diagnostic procedure (preliminary and final)…

Due to the lack of tools that can be easily used by practitioners, there is a need to develop acceptable embedded ways to assess children's fine motor skill development within early childhood education and care settings. This study examined the validity and reliability of a brief and ecologically valid fine motor assessment tool for preschool-aged…

Purpose: This study examines object permanence development in infants with motor delays (MD) compared with infants with typical development (TD) and in relation to sitting skill. Methods: Fifty-six infants with MD (mean age = 10 months) and 36 with TD (mean age = 5.7 months) were assessed at baseline and then at 1.5, 3, and 6 months postbaseline.…

Enhancing executive function in children and adolescents can have significant positive impact on their current and future daily lives. Upregulation of executive function associated with motor skill acquisition suggests that motor learning scenarios provide valuable developmental opportunities to optimize executive function. The present systematic…
