This advanced experiential course examines Sand Tray Therapy as a flexible, integrative therapeutic approach grounded in trauma-informed, neurobiological, developmental, attachment, and relational frameworks. Students will expand their theoretical and practical understanding of how metaphor within the sand tray supports emotion regulation, attachment repair, right-brain–to–right-brain coregulation, and transformation across diverse client systems. Emerging considerations in virtual play therapy and the ethical use of AI-assisted tools for clinical practice will be explored, with attention to how these technologies can extend accessibility, creativity, and co-regulation in online settings while maintaining therapeutic relational integrity.
