Alexithymia explained

Alexithymia is a trait — not a diagnosis on its own — characterised by difficulty identifying and describing your own emotions, a tendency toward externally-oriented thinking, and a constricted imaginal life. The term was coined in 1976 by Nemiah, Freyberger and Sifneos, and the most-used measure is the Toronto Alexithymia Scale, the TAS-20 (Bagby, Parker and Taylor, 1994).

It is not a moral failing, not an absence of emotion, and not a personality flaw. The body still has the same physiological response — racing heart, tight chest, heaviness in the gut — but the labels other people seem to reach for instantly come slowly, or not at all.

Around half of autistic adults score positive on the TAS-20, compared with roughly ten per cent of the general population (Kinnaird, Stewart and Tchanturia, 2019). It also overlaps with ADHD, eating disorders, and several other conditions. Neurodivergence and alexithymia are not the same thing — many autistic adults are not alexithymic — but the overlap is real and worth naming. Embrace Autism has a thorough plain-English overview if you want to dig into the autism crossover specifically.

If you have alexithymia, several patterns may sound familiar. The body knows before you do — you notice tight shoulders, a held breath, a sudden need to leave the room, well before you can name what you feel. Someone asks how you are and “fine” is the most honest answer available, because the alternative would be guessing. Or someone says “you must be furious”, and you do not recognise the description, even though the body is clearly doing something.

A common experience is being told an emotion you must be feeling, and not being able to confirm or deny. Another is finding that other people’s emotions are easier to read than your own — the trait is asymmetric in a way that can be disorienting.

The result is often a quiet self-mistrust. If you cannot reliably name what you feel, “how do you feel about this?” becomes a question with no good answer, and over time you start to doubt your own readings.

A lot of mental-health support, both clinical and casual, assumes the words are there waiting. “Name your feeling and rate it from one to ten” is a standard cognitive-behavioural-therapy move. For someone with alexithymia, the naming step is the hard part. Asking the question harder does not help.

Even the more open form — “what are you feeling right now?” — assumes the answer is available, just under a thin layer of denial or distraction. For an alexithymic reader, the honest answer is “I do not know yet”, and the question expects something else.

This is not a small mismatch. It can leave alexithymic adults assumed to be evasive, repressed, or in denial, when the actual experience is that the label is not yet accessible.

Vocabulary grows like any other kind — slowly, deliberately, with practice. A few tools members tell us help:

• Feelings wheels. Robert Plutchik’s wheel of emotions and Gloria Willcox’s similar circular diagram offer a structured set of candidate labels you can match a felt state against, rather than reaching into thin air.
• Reading widely. Fiction in particular gives you named emotions paired with described situations. Over time the pattern-match starts to work in your own life too.
• Granularity practice. Lisa Feldman Barrett’s lab has shown that people who use more, finer-grained emotion words have better mental-health outcomes (Kashdan, Barrett and McKnight, 2015). Granularity is trainable — you can build it.

None of this is fast. But the trajectory is real, and the work compounds.

A useful flip is to stop asking what you feel and start asking what your body is doing. Tight chest? Held breath? Hot face? Heavy limbs? The body-state is observable in a way the emotion sometimes is not, and once you have the body-state, you can map back to the likely emotion — angry, anxious, sad, embarrassed, overwhelmed — at your own pace.

This overlaps with interoception (pronounced in-ter-oh-SEP-shun) — the perception of internal body state — which is also often muted in neurodivergent adults. The two travel together, and the same body-scan practice helps with both. (More on this in our forthcoming Interoception explained, second post in this series.)

If you live with, work with, or care for someone with alexithymia, the most useful thing is to take “I do not know” as a real answer. It does not mean evasion. It does not mean repression. It usually means the label is not yet accessible.

Offering candidate words can help when invited — “does it feel more like frustrated or trapped?” gives a structured choice instead of an open field. So can describing your own emotional state as a starter; modelling makes the vocabulary more available without putting the other person on the spot.

What does not help is interrogation. “Are you sure you are not angry?” repeated three times will not produce a more accurate answer; it will only produce silence or a guess. Treat the slow surfacing of a label as the actual work, and give it room.
