Language does not usually change in obvious or immediate ways. It shifts gradually, often without being directly noticed at first. You tend to become aware of it in small, quiet moments. A pause before speaking. A word that suddenly feels slightly uncomfortable. A phrase that you have used many times before but now no longer sits in the same way.
If you have been working in this field for some time, you have likely experienced this. Words that once felt neutral or even appropriate begin to feel less accurate. Not necessarily because they were used with harmful intent, but because they no longer reflect your current understanding of the person, the behaviour, or the situation.
There are moments where you catch yourself mid sentence, aware that what you were about to say does not quite align with what you now believe. You might not be able to explain it immediately. It often shows up first as a feeling rather than a fully formed thought. A sense that the language does not match the complexity of the person in front of you, or the context they are in.
These moments are important. They often signal that your understanding has already shifted, even if you have not yet articulated how or why. Language tends to be one of the first places where that shift becomes visible. It highlights a gap between what you know and the words you are using to describe it.
Paying attention to that gap matters. It is where reflection begins, and it is often where practice starts to change.
Language as a Reflection of Perspective
It is easy to assume that language simply describes what we observe. In practice, it does much more than that. Language shapes interpretation. It influences how behaviour is understood, how individuals are perceived, and how situations are responded to.
The words used in reports, conversations, and day to day interactions are not neutral. They carry underlying assumptions, often without us realising. A single word can suggest intention, motivation, ability, or even character. For example, describing someone as refusing immediately implies choice, whereas describing them as unable to engage suggests a different set of underlying factors.
Over time, these patterns of language can become embedded within practice. They are repeated across teams, documents, and systems, gradually shaping a shared understanding that may not always be accurate. This is not usually intentional. It happens because language becomes familiar, and familiarity often goes unquestioned.
As your understanding develops, these assumptions begin to feel less stable. Words that once seemed precise start to feel limited. Not completely incorrect, but insufficient. They no longer capture the full context, the underlying processes, or the individuality of the person.
This is where language begins to shift. Not because of external pressure, but because your internal understanding has changed. The language starts to feel like it is simplifying something that is, in reality, far more complex.
Rethinking Diagnostic Language
This shift is particularly visible in diagnostic terminology, such as the move from autistic spectrum disorder to autistic spectrum condition.
For many years, the term disorder was used consistently across clinical and educational contexts. It carried a sense of authority and legitimacy, which meant it was rarely questioned. However, as more autistic individuals have shared their experiences, the impact of this language has been increasingly challenged.
The word disorder implies that something is inherently wrong or broken. It frames autism primarily in terms of deficit and suggests a need for correction or normalisation. While it is important to acknowledge that autistic individuals can experience significant challenges, this framing alone does not capture the full picture.
Autism also involves differences in perception, communication, sensory processing, and interaction with the environment. These differences are not simply deficits. They are variations in how individuals experience and respond to the world.
The shift towards the term condition reflects an attempt to move away from a purely deficit based model. It allows for a more balanced understanding, one that recognises both challenges and differences without reducing the individual to what they struggle with.
This change in language has practical implications. It influences how professionals think about support, how expectations are set, and how individuals are spoken to and about. It moves the focus away from fixing the individual and towards understanding and supporting them more effectively.
Shifting the Weight of Behaviour
A similar conceptual shift can be seen in the move from challenging behaviour to behaviour that challenges.
At first, this may appear to be a minor adjustment in wording. However, the impact on interpretation is significant.
Describing someone as challenging places the difficulty within the individual. Over time, this can shape how they are viewed by others. The behaviour becomes associated with who they are, rather than what is happening in a particular moment. This can lead to a fixed perception, where the individual is consistently seen through the lens of difficulty.
In contrast, behaviour that challenges shifts the focus away from the individual and towards the interaction. It acknowledges that the behaviour is experienced as difficult, but it does not define the person by it. This opens up space to consider context, including environmental factors, expectations, communication differences, and emotional states.
This shift is not just about language. It directly affects practice. When the individual is positioned as the problem, responses tend to focus on managing or controlling behaviour. When the behaviour is understood as meaningful within a context, responses are more likely to focus on understanding, adaptation, and support.
The language used shapes the questions that are asked. And the questions asked shape the interventions that follow.
Moving Away From Deficit Based Descriptions
The way communication is described has also evolved, particularly in relation to terms such as non verbal.
This term defines individuals based on what they do not do. It centres absence and can unintentionally overlook the presence of other forms of communication.
When communication is viewed more broadly, it becomes clear that it is always present. It may not involve spoken language, but it exists through gesture, movement, facial expression, behaviour, and interaction. These forms of communication are often missed because they do not align with traditional expectations.
Describing someone as communicating without spoken language provides a more accurate representation. It acknowledges difference without reducing the individual to a limitation. It also shifts responsibility. Instead of placing the focus on what the individual lacks, it highlights the need for others to adapt their understanding and interpretation.
This change in language encourages a more responsive and inclusive approach. It recognises that communication is a shared process, not something that rests solely on the individual.
Understanding Behaviour Through a Different Lens
Language also reflects how behaviour itself is understood.
For example, demand avoidance has historically been described as a reluctance or refusal to follow instructions. This interpretation often led to responses focused on increasing compliance.
More recently, there has been a shift towards understanding this behaviour as a response to anxiety, overwhelm, or a need for autonomy and control. While the observable behaviour may appear similar, the meaning behind it changes significantly.
This distinction is important because it changes the response. If behaviour is seen as defiance, interventions are likely to focus on reducing that defiance. If it is understood as a response to distress, the focus shifts towards reducing that distress and increasing a sense of safety.
Language plays a key role in this process. It shapes how behaviour is interpreted, often before any conscious analysis takes place.
Language and Emotional Interpretation
The terms used to describe behaviour also influence the emotional response of those observing it.
For example, describing behaviour as attention seeking can imply manipulation or intentionality. However, when considered more carefully, this behaviour is often about seeking connection, reassurance, or support.
Similarly, distinguishing between a tantrum and a meltdown allows for a more accurate understanding of what is happening. A tantrum is often associated with goal directed behaviour, whereas a meltdown reflects a loss of control due to overwhelm.
These distinctions are important because they influence how others respond. Language shapes not only interpretation, but also emotional reactions. It can lead to empathy and understanding, or to frustration and judgement.
What Research Is Beginning to Show
There is increasing research supporting the connection between language, understanding, and practice.
Work by Bridget A. Taylor, Linda A. LeBlanc, and Megan R. Nosik has emphasised the importance of compassionate care within behavioural practice. Their work highlights that technical accuracy alone is not sufficient if it is not accompanied by an awareness of how interactions are experienced by the individual.
Research by Anuradha Rajaraman and colleagues has further developed this perspective through a focus on trauma informed approaches. This work highlights the relationship between behaviour, safety, emotional regulation, and prior experience.
Together, this research reinforces a key point. Language is not separate from practice. It shapes how behaviour is understood, and that understanding directly influences outcomes.
Language as a Reflection of Assumptions
Language often reveals assumptions that may otherwise go unnoticed.
Words such as refusing or non compliant suggest intention and choice, even when there may be significant barriers affecting the individual’s ability to engage. These barriers might include anxiety, sensory overload, lack of understanding, or previous experiences.
When language shifts to reflect difficulty rather than choice, the interpretation changes. Describing someone as unable to engage due to overwhelm leads to different responses than describing them as choosing not to engage.
The behaviour itself may not change, but the meaning assigned to it does. This shift in meaning influences how individuals are supported and how situations are managed.
Respecting Identity and Preference
There has also been a growing recognition of the importance of individual preference in how people are described.
Some individuals prefer identity first language, while others prefer person first language. The key point is not choosing one approach as universally correct, but recognising that preference matters.
This represents a shift away from language being imposed by professionals and towards a more collaborative and respectful approach. It acknowledges individuals as active participants in how they are understood and represented.
Noticing the Shift in Your Own Practice
Think about your own practice for a moment.
Can you recall a time recently where something you said, or something you heard, did not quite sit right with you? Maybe it was a word you have used for years. Maybe it was something said in passing that stayed with you longer than you expected.
Those moments are easy to move past. You are busy, the day continues, and it can feel easier to carry on than to pause and unpack it. But those moments are often more significant than they first appear.
They usually point to something already changing in your understanding. Even if you cannot fully explain it yet, there is a sense that the language no longer fits in the way it used to.
That discomfort is not something to ignore. It is something to be curious about.
Because language is often the first place where shifts in thinking become visible. It highlights the gap between what you know and the words you are using to express it.
Paying attention to that gap is not about getting everything right or constantly correcting yourself. It is about noticing when something feels misaligned and being willing to explore why.
And that matters. Because the words you use shape how you understand the people you support. They shape how others understand them too.
When your language begins to change, your perspective changes with it. And over time, that is what leads to more thoughtful, more responsive, and more human practice.
