Today is International Stammering Awareness Day, an annual awareness initiative recognised globally to reduce stigma and promote understanding of stammering, also known as stuttering. Stammering affects the fluency of speech and is characterised by disruptions in the normal flow of speaking, including repetitions of sounds or words, prolongations of sounds, and blocks where no sound comes out.
Stammering is not caused by anxiety, poor parenting, or low intelligence. It is a neurological speech difference that affects around one percent of the general population and is significantly more common in children than adults. Many children who stammer in childhood develop fluent speech over time. Others continue to stammer into adulthood and learn to manage it effectively.
ABA therapy does not treat the neurological basis of stammering. That is the domain of speech and language therapy. What ABA can do is address the behavioural and emotional dimensions of stammering that significantly affect a child's quality of life and communication confidence.
The Behavioural Impact of Stammering
For many children who stammer, the experience of stammering in social and academic contexts produces a learned pattern of avoidance that is as clinically significant as the stammer itself.
A child who has repeatedly experienced social discomfort when stammering in class, who has been laughed at, interrupted, or given unsolicited advice about how to speak, learns to avoid speaking situations. They may stop volunteering answers in class. They may use shorter sentences or substitute words to avoid sounds that are difficult for them. They may avoid speaking to unfamiliar people. They may become increasingly anxious about situations that require communication.
This avoidance behaviour is a learned response to a history of aversive communication experiences. And avoidance-maintained behaviour is exactly what ABA is designed to address.
How ABA Addresses Communication Avoidance
The ABA approach to avoidance behaviour follows the same functional logic it applies to any other behaviour. Avoidance is maintained by negative reinforcement: avoiding a speaking situation removes the anticipated discomfort of stammering in that situation. This works in the short term and makes the avoidance more likely to be used again in future similar situations.
The clinical goal is to gradually rebuild a history of positive communication experiences that are strong enough to reduce the motivation for avoidance. This is done by systematically creating speaking opportunities that are manageable, reinforcing communication attempts genuinely regardless of fluency, and gradually increasing the challenge of speaking situations as the child's confidence develops.
The emphasis is always on the communication attempt, not on the fluency of the output. A child who stammers while communicating something effectively has communicated effectively. Reinforcing the communication rather than the fluency changes the child's own relationship with their speaking.
Reducing Anxiety Around Speaking
Anxiety about speaking is one of the most significant contributors to the cycle of avoidance in children who stammer. ABA addresses this through gradual, systematic exposure to speaking situations, starting with situations where anxiety is low and building gradually toward more demanding contexts.
This is combined with building the child's repertoire of coping strategies for difficult speaking moments, and with parent and teacher coaching to ensure the child's speaking environment is as supportive as possible.
The Role of the Environment
One of the most powerful things ABA can change for a child who stammers is not the child's behaviour but the behaviour of the adults around them. A child who stammers in a classroom where the teacher waits patiently, does not complete sentences for them, and responds to the content of their communication rather than its fluency is having a fundamentally different experience from a child in a classroom where impatience or embarrassment is the response.
Parent and teacher coaching is a core component of NeuroCore's approach when a child who stammers is on our caseload. We work with the adults in the child's environment to build the response patterns that support communication confidence rather than inadvertently reinforcing avoidance.
If you have concerns about your child's development, consult our BCBA or your pediatrician.
