Transitions in Therapy - Understanding the Nervous System Behind the Behaviour
In the therapy room, transitions are one of the most underestimated regulatory challenges we work with.
The child who is settled and engaged suddenly becomes dysregulated when it is time to move to the next activity. The session that was going well falls apart at pack-up time. None of this is random. It is neurologically predictable. And when you understand the mechanisms, it changes how you structure your sessions.
What Transitions Actually Ask of the Brain
Every transition requires a cluster of executive functions to fire in sequence. The child must inhibit their current activity, shift their attentional focus, update their internal model of what comes next, and activate a new set of expectations and behaviours. For many of the children we see in therapy, that sequence represents a significant cognitive and regulatory load.
This load does not happen in isolation. It happens on top of whatever sensory, emotional, or physiological baseline the child is already managing when they walk through our door. A child running on a heightened sensory system, low arousal, residual anxiety from the school day, or even just hunger has fewer prefrontal resources available for flexible cognitive switching.
From a polyvagal perspective, transitions also represent a real challenge to felt safety. The nervous system responds to uncertainty. For a child whose nervous system is already scanning for threat, the question “what comes next?” can shift them out of ventral vagal engagement and into a protective state before you have finished your sentence.
The Predictability Principle
The brain is a prediction machine. Its primary job is to answer “what comes next?” as efficiently as possible. When the answer is clear and stable, the nervous system can remain regulated. When the answer is uncertain, the nervous system increases its vigilance.
Even a well-anticipated transition introduces a gap in the brain’s prediction system. For most children, that gap is brief and manageable. For children with sensory processing differences, anxiety, ADHD, or autism, that gap can trigger a disproportionate stress response. The child is not being rigid or non-compliant. Their nervous system is doing exactly what it is designed to do when prediction fails.
Leaving a State of Regulation
This is the piece that is often missed in clinical thinking about transitions. We assume the child is upset because they are leaving something enjoyable. But more often, they are leaving something regulating.
Children actively seek experiences that organise their nervous system. Spinning. Rocking. Repetitive activity. Deep pressure. A particular toy or game that creates just the right level of arousal. By the time we ask them to stop, they may have finally found a nervous system state that feels manageable. Asking them to leave that state is a regulatory disruption, not a minor inconvenience. If the issue is regulation, what the child needs is support to reach regulation again before the next demand is placed.
“Every transition asks a child’s brain to give up certainty. For a nervous system that is already stretched, that is not a small ask.”
What Works in the Therapy Room
Transition supports that reduce uncertainty work because they answer the brain’s predictability question before the transition happens. Advance warnings, visual first-then boards, countdown timers, and consistent session structures all serve this function. They are not accommodations that avoid challenge. They are scaffolding that makes challenge possible.
Co-regulation matters here too. Your calm, predictable presence during a transition is regulatory information for the child’s nervous system. A therapist who remains grounded and unhurried during a transition disruption models and transmits regulation in a way that no instruction can replicate.
Building transition tolerance is a clinical goal in its own right. Naming it in your session plans, tracking progress across sessions, and communicating it to families creates continuity between the therapy room and home.
