A recent study by Denisova and Wolpert (2024) investigates how early sensorimotor features relate to cognitive differences in toddlers diagnosed with autism spectrum disorder (ASD). By examining over 1,000 children with varying IQ levels, the researchers reveal how sensorimotor variability impacts behaviors linked to autism, providing valuable insights for individualized interventions.
Background
Sensorimotor functions, which include movement and coordination, are fundamental to human interaction and learning. Despite their importance, their role in autism has been underexplored, particularly in relation to how they vary across cognitive abilities. This study bridges that gap by analyzing the connections between sensorimotor features and cognitive profiles in toddlers with ASD, shedding light on the potential mechanisms driving atypical behaviors in early childhood autism.
Key Insights
Distinct Features in Lower-IQ ASD Toddlers: Toddlers with lower IQ exhibit significantly altered sensorimotor functions, which may influence their learning and social interactions.
- Impact of IQ on Sensorimotor Features: The study finds that higher-IQ toddlers with ASD show sensorimotor patterns similar to typically developing children, suggesting resilience to atypical movement behaviors.
- Distinct Features in Lower-IQ ASD Toddlers: Toddlers with lower IQ exhibit significantly altered sensorimotor functions, which may influence their learning and social interactions.
- Implications for Autism Subtypes: These findings highlight the need to account for cognitive variability when developing interventions, as sensorimotor differences may underlie key behavioral traits in autism.
Significance
This research contributes to a deeper understanding of how sensorimotor variability interacts with cognitive abilities in autism. By identifying distinct patterns linked to IQ levels, the study underscores the importance of tailoring interventions to address the unique needs of children across the autism spectrum. The findings also encourage a broader perspective on the diversity of developmental pathways in ASD.
Future Directions
Further research could investigate the specific mechanisms through which sensorimotor differences influence learning and behavior in autism. Longitudinal studies tracking developmental changes over time may provide additional insights, helping to refine interventions. Moreover, exploring how environmental factors shape sensorimotor learning in ASD could open new opportunities for targeted therapies.
Conclusion
The work by Denisova and Wolpert (2024) highlights the role of sensorimotor features in early autism and their relationship to cognitive abilities. By focusing on individualized approaches, this research offers a foundation for developing more effective strategies to support children with autism, emphasizing the importance of addressing both cognitive and motor differences.

Understanding Preterm Cognitive Development
Preterm birth — defined as birth before 37 weeks of gestation — affects approximately 10% of all births worldwide, making it one of the most common risk factors for cognitive development differences. The brain undergoes critical growth during the third trimester, including myelination of neural pathways, synaptogenesis, and cortical folding. When birth occurs before these processes complete, the resulting developmental trajectory can differ in measurable ways.

Research consistently shows that the degree of prematurity matters: extremely preterm infants (born before 28 weeks) face the greatest cognitive challenges, while late preterm infants (34-36 weeks) often catch up to their full-term peers by school age. However, “catching up” in average scores does not mean individual outcomes are predetermined — environmental enrichment, responsive caregiving, and early intervention programs have been shown to significantly narrow developmental gaps.
Modern neonatal intensive care has dramatically improved survival rates, shifting research focus from mortality to long-term quality of life and cognitive outcomes. Longitudinal studies following preterm cohorts into adulthood reveal that while group-level differences persist, individual variation is substantial, and many preterm-born adults achieve educational and professional success comparable to their full-term peers.
Practical Implications for Parents and Clinicians
For parents of preterm infants, these findings offer both realistic expectations and grounds for optimism. While group-level statistics show average cognitive differences, individual trajectories vary enormously. Key protective factors include kangaroo care (skin-to-skin contact), responsive parenting, early enrollment in developmental follow-up programs, and creating language-rich home environments. Clinicians should provide balanced counseling that acknowledges risks without creating self-fulfilling prophecies of poor outcomes.
Early intervention services — typically available through state early intervention programs for children birth to age 3 — have demonstrated effectiveness in narrowing cognitive gaps. These services may include speech-language therapy, occupational therapy, developmental play-based interventions, and parent coaching. The earlier these services begin, the greater their potential impact, as neural plasticity is highest in the first years of life.
Frequently Asked Questions
What is cognitive ability?
Cognitive ability refers to the brain’s capacity to process information, learn from experience, reason abstractly, solve problems, and adapt to new situations. It encompasses multiple domains including verbal comprehension, perceptual reasoning, working memory, and processing speed.
How is intelligence measured?
Intelligence is primarily measured through standardized psychometric tests such as the Wechsler Adult Intelligence Scale (WAIS), Stanford-Binet, and Raven’s Progressive Matrices. These tests assess various cognitive domains and produce an Intelligence Quotient (IQ) score with a mean of 100 and standard deviation of 15.
Why does psychological research matter?
Psychological research provides the evidence base for understanding human behavior and mental processes. It informs clinical practice, educational policy, workplace design, and public health interventions. Without rigorous research, interventions risk being ineffective or harmful.
People Also Ask
What are the link between physical activity and cognitive health?
Recent research highlights how everyday physical activity can benefit cognitive health. A study by Hakun et al. (2024) examined the short-term effects of regular physical activity on mental processing speed and working memory. Using real-time assessments, the study provides new insights into how light and moderate physical activities can promote brain health in middle-aged adults.
