Child Development in the Preschool Years: How Building Independence Shapes the Skills That Last

Independence is not a trait children either have or lack when they arrive at preschool. It is a set of skills that develops over time through specific experiences, consistent environments, and relationships with adults who create space for children to try, fail, and try again.

Child development research over the past two decades is clear on this point: the skills children build between the ages of two and six, particularly self-regulation, executive function, and problem-solving capacity, are among the strongest predictors of academic success, social competence, and wellbeing across the entire lifespan.

This article covers what that research actually shows, why the preschool years are the most effective window to build these skills, and how Highland Playschool structures its programs around the developmental science.

What Child Development Research Shows About Self-Regulation

Self-regulation is the ability to manage one’s own thoughts, emotions, and behavior in order to meet a goal. In early childhood, it shows up as a child waiting their turn, staying focused on a task, managing frustration without a meltdown, or choosing between two options with some thought. These are not small things. Research published in PMC tracking 1,386 children from preschool through first grade found that the majority of children develop self-regulation rapidly during the preschool years, and that the pace and pattern of that development has measurable effects on school readiness.

A 2024 study in the Early Childhood Education Journal found that an additional year of quality preschool participation was significantly and positively associated with self-regulation scores in kindergarten. Importantly, the study also found that the quality of teacher-child interactions moderated the outcome, meaning time in a program matters, but the quality of what happens inside that time matters more.

Research published in Frontiers in Psychology in 2024 confirms that self-regulation is particularly malleable during early childhood, which makes this the most effective window to support its development. Once children move into the elementary years, the plasticity of these skills decreases and intervention requires more effort to produce the same gains.

Executive Function: The Mechanism Behind Independent Thinking

Executive function (EF) is the umbrella term for the cognitive processes that allow children to plan, focus, remember instructions, and manage competing demands. It includes three foundational components: inhibitory control (the ability to pause before acting), working memory (the ability to hold information in mind while using it), and cognitive flexibility (the ability to shift thinking or approach when needed).

Research from Wiley Developmental Science found that well-developed executive function in early childhood is linked to growth in language, literacy, and math by the end of kindergarten, academic achievement in elementary and middle school, and educational attainment measured as late as age 25. Conversely, weak executive function in the preschool years predicts learning and behavioral difficulties throughout the school years.

A PMC meta-analysis confirms considerable development of executive function occurs between ages three and six. This period is when the foundational components of EF, particularly inhibitory control and working memory, emerge and become increasingly functional. The research is consistent: the preschool years are not a waiting room for real learning. They are when the cognitive tools for all future learning are being constructed.

Three Skills That Form the Foundation of Independence

Decision-making, problem-solving, and self-help skills are the practical manifestations of executive function development. Researchers refer to them as the visible surface of what is happening neurologically beneath it. When a child chooses which book to look at during free time, they are exercising working memory and inhibitory control. When they figure out how to make a block tower that keeps falling, they are building cognitive flexibility and persistence. When they learn to dress themselves or tidy up materials, they are building both motor coordination and the internal experience of competence.

One in four preschool-aged children from lower income families experience poor emotional regulation, which directly affects academic productivity and social skills including self-control, cooperation, and empathy. This figure, drawn from research reviewed in ScienceDirect in 2024, underscores how critical the preschool environment is as an intervention point for children who might not be getting these developmental experiences at home.

A 2025 study published in the Journal of Experimental Child Psychology found that children’s self-regulation is positively related to peer acceptance and that self-regulation improves measurably between ages four and five, which is precisely the window the preschool years cover. The peer relationships formed in quality early childhood programs are not incidental. They are part of the developmental mechanism.

How the Classroom Environment Shapes Child Development

Research from the OECD and NAEYC consistently identifies the classroom environment as a primary driver of child development outcomes, not just what children are taught but how the space itself is organized. Classrooms that offer open-ended materials, child-directed time, and predictable daily routines give children repeated opportunities to make decisions and manage themselves within a safe structure.

A study published in PMC in 2024 found that preschoolers in classrooms with higher average self-regulation demonstrated larger gains in self-regulation by the end of the school year. The classroom peer environment is itself a developmental factor. Children learn self-regulation partly by being in proximity to peers who are also practicing it, and through the instructional choices that capable peers make possible.

Open-ended materials such as building blocks, art supplies, and natural loose parts are particularly well supported in the research. These materials do not have one correct answer, which means children must use working memory to hold their plan, inhibitory control to stay with it, and cognitive flexibility to revise when it does not work. Each of those cycles is a self-regulation repetition that strengthens the underlying cognitive architecture.

How Highland Playschool Supports Child Development

Highland Playschool has operated for 20 years under Maryland’s COMAR 13A.16 licensing standards and participates in Maryland Excels, the state’s quality improvement program. The school follows the Reggio Emilia approach, in which children’s own curiosity and interests guide the direction of learning rather than a fixed curriculum sequence delivered to all children at the same pace.

This model is directly aligned with the executive function research reviewed above. When children pursue questions that genuinely interest them, they maintain attention longer, exercise more working memory, and tolerate more challenge before disengaging. These are not incidental benefits. They are the developmental mechanism that the Reggio approach is specifically designed to produce.

What Parents Can Reinforce at Home

The research is clear that child development is influenced by both the school and home environment. Parents who understand what is being built in the classroom can reinforce the same skills at home in low-effort, everyday ways. Offering two real choices at mealtimes rather than open-ended questions exercises working memory and decision-making. Narrating what is happening during play helps children build the expressive language that research links to higher self-regulation trajectories. Allowing children to struggle briefly with a task before stepping in builds the tolerance for frustration that is central to independent problem-solving.

Predictable daily routines at home support what is being built at school. Children whose home schedules are consistent arrive at preschool with lower baseline stress and more cognitive resources available for learning, which is reflected in the self-regulation literature across multiple longitudinal studies.

Conclusion

Child development in the preschool years is not a passive process that happens to children simply because they are growing. It is actively shaped by the environments children spend time in, the relationships they have with educators, the materials they are given to work with, and the opportunities they are given to make decisions, face challenges, and manage themselves in the presence of peers.

The research is consistent and compelling: the skills built in a quality early childhood program between the ages of two and six predict academic performance, social competence, and life outcomes measured decades later. Independence in a young child is not an educational nicety. It is the observable evidence that child development is happening as it should.
