Mapping the Patterns, Not Just the Labels
ADHD and HSP: Part II
In Part I, I explored the idea that ADHD can explain a lot, but not always everything.
For some people, there is a “different kind of too much” in their emotional and sensory life that ADHD does not fully capture. High sensitivity, or HSP, offers one way of understanding that second layer of wiring.
In this second part, I want to move from the big picture into the details. Rather than talk about sensitivity as one vague thing, I want to look at the specific domains that researchers now use to describe it and how those domains can overlap with, differ from, or sit alongside ADHD patterns.
I’m not trying to arm you with a checklist. I want to help you begin seeing where your own experience clusters. This matters, because similar looking behaviours can have different roots. If we are vague about what is happening, we usually end up vague about what might help.
Six domains of high sensitivity
Recent work on high sensitivity has moved away from treating it as a single blob of “being sensitive” and towards a more granular model. The revised HSP scale (HSP‑R) breaks the trait down into six domains:
Depth of processing
Sensitivity to positive experiences
Social sensitivity
Emotional reactivity
Overstimulation
Sensitivity to detail
You do not need to remember the labels but the shape of each domain and how it might show up in real life.
Depth of processing
Depth of processing is about how you think, not how fast. Highly sensitive people often process things in layers. They reflect, connect, and consider implications. They may take longer to decide because they have actually thought about more angles.
In ADHD, the inner world can be busy in a different way. The mind may race, bounce, and generate ideas quickly. There can be a lot of content, but not always a lot of depth before action. Task switching, novelty seeking, and impulsivity can mean that thoughts move on before they have settled.
In practice, this can look like:
Someone with strong depth of processing replaying a conversation to understand what was really going on. They are looking for meaning, pattern, insight.
Someone with ADHD overthinking three other conversations, five future scenarios, and twelve possibilities at once because their brain is not sure where to park its attention.
From the outside, both can look like “thinking too much”. Internally, the engine is not quite the same.
Sensitivity to positive experiences
Sensitivity to positive experiences is one of the most overlooked aspects of high sensitivity. It describes how strongly a person responds to what is beautiful, nourishing, aligned, or meaningful. It includes music, nature, intimacy, humour, insight, colour, and any moment that feels quietly ‘right’.
For someone high in this domain, positive experience does not just feel nice. It resonates deeply. It can be a genuine source of recovery. Small “good” things have disproportionate impact.
ADHD also has a relationship with positive experience, although with a different flavour. The ADHD nervous system is often described as “interest driven”. It tunes in more easily when something is novel, urgent, exciting, or personally meaningful. It can struggle when things feel flat, repetitive, or low in stimulation.
Put these together and you can have:
A person whose ADHD seeks stimulation and novelty, and whose HSP trait is deeply nourished by very subtle positives.
If they assume they only need “more excitement” because of ADHD, they may miss the importance of quiet beauty, stillness, and depth in their actual nervous system care. If they assume they only need calm because of high sensitivity, they may underestimate their ADHD need for genuine interest.
Social sensitivity
Social sensitivity refers to how attuned someone is to the emotional climate around them. It is not simply “being a good people person”. It is about noticing tone, micro‑expressions, pace, shifts in energy, and unspoken tension.
An HSP with high social sensitivity might pick up on the fact that one person in the meeting is slightly withdrawn, or that two colleagues are subtly out of step with one another, long before anything overt is said. They may sense warmth, strain, boredom, or unease in the room in a way that feels immediate.
ADHD can also influence social experience, but often through a different route. Attention and executive function challenges can make it harder to track everything that is happening in a conversation. Time blindness, distractibility, and emotional intensity can mean that signals are missed, misread, or overinterpreted. Emotional history and masking can also colour how interactions are perceived.
There is a further layer where people‑pleasing can join the party. Social sensitivity can be recruited by old survival strategies. If someone has learned that reading the room and pleasing others is how they stay safe, their natural attunement can be turned into a constant scanner for other people’s needs.
The key distinction is that:
High social sensitivity is about noticing and feeling.
People‑pleasing is about what you do with that noticing.
The trait itself is not the behaviour. Recognising that difference is important if you want to reduce people‑pleasing without flattening sensitivity altogether.
Emotional reactivity
Emotional reactivity describes how strongly and quickly someone responds emotionally to what happens. It covers both positive and negative reactions. This domain is not about drama for the sake of it. It is about intensity.
In ADHD, emotional experience can also be intense. Many adults with ADHD recognise rapid shifts, big waves, and feelings that seem to hang around longer than they want them to. Research increasingly points to emotional self‑management as a significant part of the ADHD picture.
So what is different?
High sensitivity tends to amplify how deeply experience lands, especially when the environment is rich in emotional or sensory content. A person may have strong feelings and also a strong capacity to sense nuance within those feelings. The texture of emotion matters as much as its amplitude.
ADHD-related emotional difficulties are more usually concerned with regulations. The feelings are there, they can be large, and the challenge is managing their impact on behaviour, focus, and relationships alongside everything else that is going on.
From the inside, someone may know the difference between:
“I feel this deeply because I am wired to respond strongly” and
“I cannot get my system to settle, even when I want to.”
Both are real. They ask for different kinds of support.
Overstimulation
Overstimulation is one of the more obvious HSP domains. It describes hitting a saturation point when there is too much input, too much intensity, or too much contact.
For an HSP, overstimulation might show up as:
Needing to leave a noisy social event earlier than others.
Feeling suddenly exhausted in a busy open‑plan office.
Finding that their “battery” drains quickly in environments that are loud,crowded, emotionally dense, or visually cluttered.
ADHD can also involve something that is often referred to as “overwhelm”. There may be too many tasks, too many demands, too many unfinished loops, and not enough executive function to manage it all efficiently. The brain feels crowded, not necessarily the senses.
These two experiences can coexist. A person can be overstimulated, overwhelmed, or both.
The difference is that;
Overstimulation is often driven by the quality and quantity of input, while overwhelm is often driven by load, complexity, and demand.
Separating those two can help you decide whether what would help most today is reducing sensory input, reducing task load, or both.
Sensitivity to detail
Sensitivity to detail is about noticing small features of the environment. This can include changes in light, sound, temperature, arrangement, or the way people are positioned. It can also include tiny shifts in tone, pace, and emphasis.
An HSP high in this domain might notice that a picture has been moved, that a sound is slightly off, or that a conversation has picked up a faint edge that was not there before. They may remember sensory or relational details from previous experiences with surprising clarity.
ADHD often plays out differently here. Attention to detail can be inconsistent. Some things get hyper‑focused on, particularly when interest is high. Other details are missed entirely when boredom or fatigue takes the wheel. Mistakes can come from distraction rather than from a lack of capacity to notice.
The combination can produce:
A person who notices tiny atmospheric details but forgets to reply to the email.
Someone who picks up a subtle shift in a relationship long before anyone else, yet misplaces their keys three times in one morning.
Recognising that can ease a lot of confusion. It is not that you are universally “bad at detail”. It may be that you are very good at some kinds of detail and inconsistent with others, depending on interest, load, and context.
Where HSP and ADHD patterns meet
By now you may recognise that some of these domains sound very familiar, while others feel more peripheral. You may also notice that some of the ADHD experiences you know well sit close to these sensitivity domains.
There is real overlap.
Both ADHD and HSP can involve:
Feeling easily overstimulated in certain environments.
Having a strong response to emotional tone.
Looking inconsistent from the outside.
Being intuitive, creative, and perceptive.
The danger is treating the overlap as sameness. When we do that, we risk giving every difficult experience the same label and reaching for the same solution. If all intensity is “just ADHD”, we miss the parts that belong to sensitivity. If everything is “because I am HSP”, we may miss important executive function or emotional regulation dynamics that are part of ADHD.
Where people‑pleasing joins in
There is one extra pattern that often complicates this picture, and that is people‑pleasing.
In my experience as a coach, people‑pleasing is not a trait. It is a learned survival strategy. It often grows out of earlier environments where keeping others comfortable was how someone stayed safe, loved, or accepted.
High sensitivity can make people‑pleasing more effective, because the person has more data about how others are feeling. ADHD can make people‑pleasing more likely, because advocating for oneself is harder when executive function, emotional experience, and shame are already burning attention.
If we are not careful, we can end up treating people‑pleasing as “just sensitivity”, which risks reinforcing it. It is more accurate to treat social sensitivity as a neutral trait and people‑pleasing as one possible, but not inevitable, way that trait has been used.
Why this mapping matters
All of this might sound rather abstract until you bring it back to daily life.
If you know that your nervous system is both ADHD and highly sensitive, and you have some sense of which sensitivity domains are strongest for you, you can begin to map situations more accurately.
You can start to ask:
Is this difficulty coming mainly from task load and executive function?
Is it coming mainly from sensory and emotional input?
Is it coming from an old survival strategy playing out in social space?
Or is it a blend of all three.
The answers will not be perfect. Life is messier than that. But even a rough sense of patterns can change what you try next.
In Part III, I will move from mapping into lived examples. I will share composite stories from coaching that show how ADHD and high sensitivity interact in real lives, how people‑pleasing plays into that, and what begins to shift once people see these patterns more clearly.
For now, if you recognise yourself in several of these domains it may be a sign that you are carrying more data, feeling more, and responding more deeply than the environment was designed for. The work ahead is not to become less you. It is to become more deliberate in how you work with the wiring you have.
Next steps
If this article has stirred something for you, you might find these next steps helpful.
First, if you have not yet read Part I, “ADHD and HSP: A Different Kind of Too Much”, that is the best place to start. It sets out why high sensitivity matters alongside ADHD, and how we got to this map in the first place.
Second, if you recognise yourself in several of these sensitivity domains and want to explore how they show up in your own life, this is exactly the kind of territory I work with in coaching. You can book an introductory call to see whether working together feels like a good fit.
Finally, you may want to notice, over the next few days, which question from this article stays with you. Is it about task load, sensory input, or old survival patterns. Often the question that echoes longest is the one that points towards your next piece of work.
