Where Regulation, Interoception, & Executive Function
Come Together
Most executive function approaches begin by teaching skills. But children cannot consistently use executive function skills when regulation, interoception, movement, and nervous system state are not supported first.
The Executive Function Institute provides one integrated body-first system that helps professionals understand what is underneath behavior and support the access children need for participation, learning, and executive function.
Why Traditional Executive Function Approaches Often Fall Short
Children are often expected to plan, organize, shift, and persist before their bodies feel safe, supported, or understood.
When internal signals are unclear or overwhelming, executive function becomes difficult to access. What may appear as defiance, lack of motivation, or inattention often reflects a nervous system working hard to manage internal and environmental demands.
Executive function does not operate apart from the body. It develops through body awareness, regulation, and supportive environments.
When adults understand the brain–body connection, intervention shifts from correcting behavior to supporting the system. This helps identify what behavior is communicating and where access may be breaking down.
Behavior is the most visible part of a much deeper system. From roots to fruit, behavior reflects the interaction of multiple systems working together.
How Behavior Develops:
Context & Safety → Sensory Input → Interoception → Executive Function → Participation → Behavior
Traditional Approaches
-
Focus on behavior first
-
Teach executive function as isolated skills
-
Depend heavily on compliance
-
Assume the child can already access the strategy
-
Separate regulation from participation
The Executive Function Institute™ Approach
-
Starts with nervous system access
-
Connects regulation and executive function
-
Supports interoception and movement first
-
Looks beneath behavior
-
Builds participation through body-based support
State Determines Access
Children cannot consistently use executive function skills when the nervous system is overwhelmed, disconnected, under-responsive, or overloaded.
Executive function is not simply taught. It must first become accessible.
The Roots to Fruit, Integrated Interoception Tree Model™ and Executive Function Express™ work together to help professionals understand what is happening underneath behavior and support the systems that allow participation, learning, and executive function to emerge.
FOUNDATION
Roots to Fruit, The Integrated Interoception Tree Model™
A body-first framework that explains how regulation, sensory processing, interoception, movement, and nervous system state shape access to participation and executive function.
APPLICATION
The Executive Function Express Program™
Executive Function Express™ translates the foundation into practical, movement-based executive function supports.
Using the train system metaphor helps professionals support regulation, participation, organization, flexibility, planning, and self-management through a body-first lens.
The Executive Function Institute integrates body-first clinical reasoning with practical executive function support.
One Connected System
Start Where You Need Support
Whether you are trying to understand behavior, support regulation, build executive function, or strengthen participation, the Executive Function Institute provides connected tools that work together within one body-first system.
About The Executive Function Institute
The Executive Function Institute provides body-first, neuro-affirming frameworks and tools that support children’s participation across settings.
Grounded in the From Roots to Fruit model, the Institute brings together assessment, intervention, and education to help professionals and families understand development from the inside out.
Founded by Dr. Cara Koscinski, occupational therapist and educator.
From Understanding to Action
When we understand how the body supports development, we can move beyond surface-level solutions and create meaningful change.
The From Roots to Fruit™ framework provides a clear path from understanding to intervention, helping children access participation, build skills, and engage more fully in everyday life.
