Motor Skills and Executive Function in Autism
Megan MacDonald, Ph.D., and Megan McClelland, Ph.D., discuss emerging research on the relationship between motor skill development and executive function in autism. They define motor skills and executive function, discuss their long-term impact on health and academic success, and consider their co-development during childhood and adolescence. The speakers highlight the importance of EF and motor skills in daily life, underscoring their malleability and potential for learning and building new skills. MacDonald and McClelland consider the effect of cultural contexts on skill development before the Q&A session.
Executive function
McClelland defines executive function (EF) as cognitive processes/skills like attention, working memory, and inhibitory control that lay the foundation for self-regulation (3:20). She explains that EF skills have emerged as a key indicator for a variety of short and long-term behaviors, including social competence in children and academic success throughout adolescents and early adulthood (4:55). She notes a recent publication that found that children with strong attention/persistence at age four had nearly 50% greater odds of completing university by age 25, underscoring long-term health, educational, and employment outcomes associated with EF (6:10).

- Predictors of early growth in academic achievement: the head-toes-knees-shoulders task (McClelland et al., 2013)
Motor skills
MacDonald discusses gross motor skills, highlighting their importance for everyday activities like walking, running, lifting, and throwing. Both EF and motor skills are foundational for learning and early development, and children begin to have a core set of motor skills between seven and eleven years old (6:25). The speaker relates motor skills to a mountain of motor development, where each level builds on top of the last (8:15). Fine motor skills involve coordinating perceptions with motor movements (visuomotor integration), allowing us to control handwriting, buttoning shirts, drawing, and coloring in the lines. Visuomotor integration has also been linked to children’s academic success (8:25).
Motor skills in autism
The presenter briefly reviews key autistic characteristics and prevalence rates, highlighting the role of gross motor skills in social and physical development during childhood (9:20). She cites references to motor skill deficits dating back to the first descriptions of autism. MacDonald explains that early delays in motor development milestones (i.e., walking and crawling) are common in autistic children and that parents/caregivers may start noticing delays between fourteen and twenty-four months (10:50). Motor skills used by school-aged children are different and center around social interactions and sports (12:48).

- Fine Motor Skills and Executive Function Both Contribute to Kindergarten Achievement (Cameron et al., 2012)
Motor skill development
MacDonald outlines one of her publications on gross motor development across the first three years of life in autistic children (13:30). Gross motor skill development for autistic children showed consistent delays at each check-up, with children being nearly one year behind expected development targets by age three (14:15). Similarly findings for fine motor skill development in autistic children was slightly more than one year behind expected development by age three (15:15). Another study on school-aged children found that kids between ten and twelve years old were chronologically about half their age in terms of motor skill development (16:05). Therefore, the speaker asserts that gross and fine motor skill development in autism is delayed in autism from early life at least through childhood.
Despite these delays, the speaker remains hopeful and iterates to viewers that motor skills are incredibly malleable and can be taught and improved with time (17:15). McClelland cites accumulating research suggesting that EF skills are a vital buffer/protective factor for children experiencing early risk factors. She reiterates that EF and motor skills are highly malleable and that we can do a lot to improve these aspects of development in autistic children (18:00).

Executive function and motor skills
McClelland discusses contemporary evidence suggesting the co-development of EF and motor skills in young children. She explains that some brain regions are involved in both EF and motor skill development, and certain EF traits (e.g., memory and inhibitory control) are related to fine motor skills (19:00). McDonald notes that, until very recently, motor skills and EF were studied independently. She highlights contemporary collaborative research and its importance in understanding autism (20:50).

- Relations of Preschoolers’ Visual-Motor and Object Manipulation Skills With Executive Function and Social Behavior (MacDonald et al., 2016)
Cultural contexts
McDonald states that fine motor skills are associated with cognitive flexibility but that much of the research is based in the U.S. or other Western countries (22:20). A recent study found that Chinese children exhibit better fine motor skill performance while U.S. students have better object control skills (23:00). Similarly, gross motor skills of pre-schoolers in China were significantly lower than pre-schoolers in the U.S. Such findings, the speaker asserts, suggest that different cultures emphasize different skill sets in early life (fine vs gross) (24:15).
The speaker outlines a recent survey study on EF and motor skills in autistic children from Taiwan and the U.S. (24:45). She outlines data collection and analysis methods, including regressions and covariates (26:10). Results show that motor skills are associated with EF across countries. Further, the relationship between EF and motor skills is culturally comparable, with significant and positive correlations of magnitude in both countries. She asserts that this preliminary evidence suggests the relationship between EF and motor skills is not specific to region or culture (27:15).

Conclusions
McClellan reviews the presentation, highlighting that EF and motor skills contribute to healthy development and academic success for children from diverse backgrounds. She reiterates the malleability of these skills and their importance for daily activities. The speaker considers how improvements in EF may impact motor skills and vice versa (28:13). She gives thanks and acknowledgments before the Q&A, where the presenters discuss the impact of COVID on EF, intervention options, monitoring EF supports in daily life, the importance of routine and planning, and much more (30:20).

Cited Studies
Children’s behavioral self-regulation and executive function (EF; including attentional or cognitive flexibility, working memory, and inhibitory control) are strong predictors of academic achievement. The present study examined the psychometric properties of a measure of behavioral self-regulation called the Head-Toes-Knees-Shoulders (HTKS) by assessing construct validity, including relations to EF measures, and predictive validity to academic achievement growth between prekindergarten and kindergarten. In the fall and spring of prekindergarten and kindergarten, 208 children (51% enrolled in Head Start) were assessed on the HTKS, measures of cognitive flexibility, working memory (WM), and inhibitory control, and measures of emergent literacy, mathematics, and vocabulary. For construct validity, the HTKS was significantly related to cognitive flexibility, working memory, and inhibitory control in prekindergarten and kindergarten. For predictive validity in prekindergarten, a random effects model indicated that the HTKS significantly predicted growth in mathematics, whereas a cognitive flexibility task significantly predicted growth in mathematics and vocabulary. In kindergarten, the HTKS was the only measure to significantly predict growth in all academic outcomes. An alternative conservative analytical approach, a fixed effects analysis (FEA) model, also indicated that growth in both the HTKS and measures of EF significantly predicted growth in mathematics over four time points between prekindergarten and kindergarten. Results demonstrate that the HTKS involves cognitive flexibility, working memory, and inhibitory control, and is substantively implicated in early achievement, with the strongest relations found for growth in achievement during kindergarten and associations with emergent mathematics.
A considerable body of research indicates that children’s executive function (EF) skills and related school readiness constructs are important for early learning and long-term academic success. This review focuses on EF and a related construct, motor skills with a focus on visuomotor integration, as being foundational for learning, and describes how these skills codevelop in young children in bidirectional and synergistic ways. The review discusses definitional and conceptual issues, connects EF and visuomotor integration to relevant theoretical perspectives, discusses measurement issues and advancements, and reviews intervention evidence to support the malleability of these skills in young children. Discussion emphasizes how these skills develop together and suggests that research examining children’s learning from a codevelopment perspective can help promote children’s health and well-being.

Duncan et al. (2007) presented a new methodology for identifying kindergarten readiness factors and quantifying their importance by determining which of children’s developing skills measured around kindergarten entrance would predict later reading and math achievement. This article extends Duncan et al.’s work to identify kindergarten readiness factors with 6 longitudinal data sets. Their results identified kindergarten math and reading readiness and attention as the primary long-term predictors but found no effects from social skills or internalizing and externalizing behavior. We incorporated motor skills measures from 3 of the data sets and found that fine motor skills are an additional strong predictor of later achievement. Using one of the data sets, we also predicted later science scores and incorporated an additional early test of general knowledge of the social and physical world as a predictor. We found that the test of general knowledge was by far the strongest predictor of science and reading and also contributed significantly to predicting later math, making the content of this test another important kindergarten readiness indicator. Together, attention, fine motor skills, and general knowledge are much stronger overall predictors of later math, reading, and science scores than early math and reading scores alone.
This study examined the contribution of executive function (EF) and multiple aspects of fine motor skills to achievement on 6 standardized assessments in a sample of middle-socioeconomic status kindergarteners. Three- and 4-year-olds’ (n = 213) fine and gross motor skills were assessed in a home visit before kindergarten, EF was measured at fall of kindergarten, and Woodcock–Johnson III Tests of Academic Achievement were administered at fall and spring. Correlations indicated that EF and fine motor skills appeared distinct. Further, controlling for background variables, higher levels of both EF and fine motor skills, specifically design copy, predicted higher achievement on multiple subtests at kindergarten entry, as well as improvement from fall to spring. Implications for research on school readiness are discussed.
With increased interest in the early diagnosis and treatment of children with autism spectrum disorders (ASD), more attention has been called to the motor skills of very young children with ASD. This study describes the gross and fine motor skills of a cross-sectional group of 162 children with ASD between the ages of 12 and 36 months, as well as a subset of 58 children followed longitudinally. Gross motor and fine motor age equivalent scores were obtained for all children. A ‘motor difference’ variable was calculated for each child’s gross and fine motor skills by taking the absolute difference of the children’s age equivalent motor score and their respective chronological age. In Study 1 (the cross-sectional analysis), ANCOVA (co-varied for nonverbal problem solving) revealed significant group differences in the gross motor and fine motor age difference variables. Post-hoc analysis revealed that gross motor and fine motor differences became significantly greater with each 6-month period of chronological age. In Study 2, 58 children were measured twice, an average of 12 months apart. Results indicate that the gross motor and fine motor difference scores significantly increased between the first and second measurements. The importance of addressing motor development in early intervention treatments is discussed.
Delays and deficits may both contribute to atypical development of movement skills by children with ASD. Fundamental movement skills of 25 children with autism spectrum disorders (ASD) (ages 9–12 years) were compared to three typically developing groups using the Test of Gross Motor Development (TGMD-2). The group matched on chronological age performed significantly better on the TGMD-2. Another comparison group matched on movement skill demonstrated children with ASD perform similarly to children approximately half their age. Comparisons to a third group matched on mental age equivalence revealed the movement skills of children with ASD are more impaired than would be expected given their cognitive level. Collectively, these results suggest the movement skills of children with ASD reflect deficits in addition to delays.
Research on the development of self-regulation in young children provides a unifying framework for the study of school readiness. Self-regulation abilities allow for engagement in learning activities and provide the foundation for adjustment to school. A focus on readiness as self-regulation does not supplant interest in the development of acquired ability, such as early knowledge of letters and numbers; it sets the stage for it. In this article, we review research and theory indicating that self-regulation and consequently school readiness are the product of integrated developmental processes at the biological and behavioral levels that are shaped by the contexts in which development is occurring. In doing so, we illustrate the idea that research on self-regulation powerfully highlights ways in which gaps in school readiness and later achievement are linked to poverty and social and economic inequality and points the way to effective approaches to counteract these conditions.
This study examined relations among early family risk, children’s behavioral regulation at 54 months and kindergarten, and academic achievement in first grade using data on 1298 children from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development. Family risk was indexed by ethnic minority status, low maternal education, low average family income from 1 to 54 months, and high maternal depressive symptoms from 1 to 54 months. Results of structural equation modeling indicated that minority status, low maternal education, and low family income had significant negative effects on reading, math, and vocabulary achievement in first grade. Modest indirect effects were also found from ethnicity, maternal education, and maternal depressive symptoms, through 54-month and kindergarten behavioral regulation to first-grade achievement. Discussion focuses on the importance of behavioral regulation for school success especially for children facing early risk.

The present study explored direct and interactive effects between behavioral self-regulation (SR) and two measures of executive function (EF, inhibitory control and working memory), with a fine motor measure tapping visuomotor skills (VMS) in a sample of 127 prekindergarten and kindergarten children. It also examined the relative contribution of behavioral SR, EF, and VMS skills for concurrent academic achievement. Results indicated that a measure of working memory (WJ-Working Memory) and a measure of behavioral SR (Head–Toes–Knees–Shoulders task; HTKS) were directly related to VMS. Differential relations were also examined for prekindergarten and kindergarten children. Results revealed a significant interaction between age and inhibitory control (Day–Night), and an interaction at a trend level between age and working memory suggesting both tasks are more related to VMS skills for younger children. Results also indicated that behavioral SR, EF, and VMS skills were differentially related to the three achievement outcomes. Both behavioral SR and VMS were significantly related to math, behavioral SR, EF, and VMS were significantly related to emergent literacy, and behavioral SR and EF were related to vocabulary scores. Results point to significant relations between behavioral SR and EF with VMS, and how each is related to early academic achievement in preschool and kindergarten.
Visuomotor integration (VMI), or the ability to copy designs, and 2 measures of executive function were examined in a predominantly low-income, typically developing sample of children (n = 467, mean age 4.2 years) from 5 U.S. states. In regression models controlling for age and demographic variables, we tested the interaction between visuomotor integration (design copying) and inhibitory control (pencil-tap) or verbal working memory (digit span) on 4 directly assessed academic skills and teacher-reported approaches to learning. Compared with children with both poor visuomotor integration and low inhibitory control, those on the higher end of the continuum in at least 1 of these 2 skills performed better across several dependent variables. This compensatory pattern was evident for longitudinal improvement in print knowledge on the Test of Preschool Early Literacy (TOPEL), with similar though marginally significant findings for improvement in phonological awareness (TOPEL) and teacher-rated approaches to learning on the Preschool Learning Behaviors Scale (PLBS). Of note, the same compensatory pattern emerged for concurrently measured receptive vocabulary on the Peabody Picture Vocabulary Test (PPVT), expressive vocabulary on the Woodcock-Johnson III (WJ), TOPEL phonological awareness, and teacher-rated approaches to learning. The consistent pattern of results suggests that strong visuomotor integration skills are an important part of school readiness, and merit further study.

Objective: This experiment tested the hypothesis that exercise would improve executive function. Design: Sedentary, overweight 7- to 11-year-old children (N = 171, 56% girls, 61% Black, M ± SD age = 9.3 ± 1.0 years, body mass index [BMI] = 26 ± 4.6 kg/m², BMI z-score = 2.1 ± 0.4) were randomized to 13 ± 1.6 weeks of an exercise program (20 or 40 min/day), or a control condition. Main Outcome Measures: Blinded, standardized psychological evaluations (Cognitive Assessment System and Woodcock-Johnson Tests of Achievement III) assessed cognition and academic achievement. Functional MRI measured brain activity during executive function tasks. Results: Intent to treat analysis revealed dose-response benefits of exercise on executive function and mathematics achievement. Preliminary evidence of increased bilateral prefrontal cortex activity and reduced bilateral posterior parietal cortex activity attributable to exercise was also observed. Conclusion: Consistent with results obtained in older adults, a specific improvement on executive function and brain activation changes attributable to exercise were observed. The cognitive and achievement results add evidence of dose-response and extend experimental evidence into childhood. This study provides information on an educational outcome. Besides its importance for maintaining weight and reducing health risks during a childhood obesity epidemic, physical activity may prove to be a simple, important method of enhancing aspects of children’s mental functioning that are central to cognitive development. This information may persuade educators to implement vigorous physical activity. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
Purpose: The purpose of this article was to examine specific linkages between early visual-motor integration skills and executive function, as well as between early object manipulation skills and social behaviors in the classroom during the preschool year. Method: Ninety-two children aged 3 to 5 years old (Mage = 4.31 years) were recruited to participate. Comprehensive measures of visual-motor integration skills, object manipulation skills, executive function, and social behaviors were administered in the fall and spring of the preschool year. Results: Our findings indicated that children who had better visual-motor integration skills in the fall had better executive function scores (B = 0.47 [0.20], p < .05, β = .27) in the spring of the preschool year after controlling for age, gender, Head Start status, and site location, but not after controlling for children’s baseline levels of executive function. In addition, children who demonstrated better object manipulation skills in the fall showed significantly stronger social behavior in their classrooms (as rated by teachers) in the spring, including more self-control (B − 0.03 [0.00], p < .05, β = .40), more cooperation (B = 0.02 [0.01], p < .05, β = .28), and less externalizing/hyperactivity (B = − 0.02 [0.01], p < .05, β = − .28) after controlling for social behavior in the fall and other covariates. Conclusion: Children’s visual-motor integration and object manipulation skills in the fall have modest to moderate relations with executive function and social behaviors later in the preschool year. These findings have implications for early learning initiatives and school readiness.
The purpose of this study was to examine the relationship between parent ratings of motor skills and executive function (EF) in children with autism spectrum disorder (ASD) in the United States and Taiwan. One hundred and seventy-two parents/legal guardians of children (4–6 years and 11 months old) with ASD were recruited from two countries, Taiwan (n = 100) and the United States (n = 72). The parents or guardians of the child with ASD completed a questionnaire including demographic information, child’s motor skills (using Children Activity Scale – Parents, ChAS-P), and child’s EF (using Childhood Executive Functioning Inventory, CHEXI). A series of hierarchical multiple regressions were conducted to determine whether ChAS-P (total motor score, fine motor skills, and gross motor skill) was associated with CHEXI (total EF score, working memory, and inhibition), after controlling for covariates (i.e., age, gender, race, body mass index, whether children received physical activity or cognitive training, parental education level).
