The proposed protocol, "Play, Learn, Thrive," synthesizes findings from neuroscience, molecular sciences, developmental psychology, and positive psychology. It is designed as a stepwise framework that guides children with ASD through progressive levels of play engagement while monitoring both psychological and biological outcomes. The protocol emphasizes three domains: neurobiological modulation (via molecular markers such as oxytocin, cortisol, and BDNF), psychological scaffolding (via developmental tasks and therapeutic alliance), and positive development (via flourishing metrics and well-being assessments).

Central to the protocol is the integration of multimodal play activities—ranging from sensory play, cooperative play, and imaginative storytelling to digital play platforms. Each activity is selected not only for its developmental relevance but also for its neurobiological impact. For instance, rhythmic play (e.g., drumming, clapping games) synchronizes neural oscillations, enhances gamma activity linked to cognition, and builds social synchrony (Large & Snyder, 2009). Symbolic play, meanwhile, activates the prefrontal cortex and fosters mental flexibility. By systematically sequencing these activities, the protocol creates a developmental arc supported by both psychological theory and molecular evidence.

Implementation involves therapists, caregivers, and educators, with specific guidelines for fidelity and flexibility. Data collection includes standardized behavioral assessments, caregiver reports, and potential biomarkers such as salivary cortisol (Adam & Kumari, 2009). This integrative design ensures that "Play, Learn, Thrive" is both evidence-based and adaptable across settings.

An expanded version of the protocol proposes cross-setting generalization. For instance, school-based play sessions can be linked with home-based digital games that reinforce the same neurocognitive skills. In addition, mindfulness-infused play (yoga-based games, breathing rhythms embedded in play) adds parasympathetic activation benefits, further supporting resilience. This broadened integration ensures that thriving is not an isolated clinical outcome but a pervasive lifestyle change.
