This training will introduce and examine the Developmental, Individual-differences, Relationship-based (DIR) model, which is an evidence-based framework to understand and promote development that was developed by Dr. Stanley Greenspan. DIR® is the Developmental, Individual-differences, and Relationship-based model (pronounce each letter as an initialism: D.I.R.). DIR provides a foundational framework for understanding human development and learning and how each person individually perceives and interacts with the world differently. It outlines the critical role social-emotional development has on overall human development starting at birth and continuing throughout the lifespan. The model highlights the power of relationships and emotional connections to fuel development. Through a deep understanding of the "D" ( the developmental process) and the "I" (a person's individual differences) we can use the "R" (human relationships) to promote healthy development and to help everyone reach their fullest potential. This training will present an introduction to the DIRFloortime (AKA Floortime) approach, with the developmentally appropriate interactions, interventions, and practices geared to each individual’s developmental profile.
