Abstract:

Educational neuroscience increasingly recognizes that cognitive performance in early childhood is closely linked to sensory-motor experience and emotional regulation. Within an Eco-Neurobiological framework, the developing brain is viewed as an adaptive, experience-dependent system shaped by embodied interaction with the environment. Tactile and proprioceptive stimulation contribute to arousal modulation, attentional control, and executive functioning by influencing neural networks involved in stress regulation and cognitive readiness. Clay, as a natural and malleable multisensory material, provides continuous tactile feedback and graded resistance that may facilitate embodied self-regulation and attentional stabilization. Such sensory engagement may support the integration of bottom-up regulatory processes with emerging top-down executive control. Despite its widespread classroom use, empirical evidence regarding its direct cognitive and behavioral effects in structured educational contexts remains limited.

This study examined whether short clay engagement enhances concentration, improves performance under cognitive stress, and supports adaptive behavior among kindergarten children aged five to six. We hypothesized that tactile-proprioceptive engagement would reduce cognitive load and enhance attentional efficiency under mild performance pressure.

A within-subject experimental design was implemented with 68 children from two public kindergartens. Each participant served as their own control to minimize variability. Children completed a computerized 16-piece puzzle under two conditions:
(1) baseline and
(2) stress-induced, requiring completion 20% faster than their individual baseline time.

Following initial assessment, children engaged freely with clay for approximately 20 minutes in a naturalistic classroom environment emphasizing autonomous manipulation and sustained manual engagement. Participants then repeated both puzzle conditions. Behavioral functioning was assessed through structured non-participant observations using selected Social Skills Rating System (SSRS) indicators focusing on attention persistence, impulse control, peer interaction, and emotional responsiveness. Pre–post differences were analyzed using paired statistical comparisons.

Clay engagement was associated with significant improvements across cognitive and behavioral measures. Mean puzzle completion time improved by 20% under baseline conditions and by 37% under stress-induced conditions, indicating enhanced attentional regulation and resilience under time constraints. Observational data showed a 52% increase in positive adaptive behaviors and a 45% decrease in negative behaviors, reflecting improved emotional modulation and reduced impulsivity. Improvements were consistent across both kindergarten groups, supporting ecological validity within authentic classroom settings.

Brief clay-based sensory engagement appears to support attentional efficiency, stress tolerance, and social-emotional functioning in early childhood settings. Findings align with embodied cognition and sensory-regulation models suggesting that structured tactile input facilitates executive readiness and adaptive classroom participation. Although based on a within-subject design without an external control group, results provide preliminary evidence supporting clay as a low-cost regulatory tool that can be integrated into daily kindergarten routines without specialized equipment.
