One of the most persistent, damaging, and factually incorrect things people say about autism is that autistic people lack empathy. Every autistic person, every autism parent, every autism-experienced clinician has heard some version of this claim, and it is one of the reasons autistic people are so consistently misjudged.
The problem is that a real thing is being described, but the wrong name has been attached to it. Autistic people are not less capable of caring about others. What is often being observed is a specific, well-documented, measurable phenomenon called alexithymia, and it is a completely different thing from empathy. Recognizing the difference changes almost everything about how families, teachers, and clinicians support autistic children.
Approximately 50% of autistic people meet alexithymia criteria, compared to around 10% of the general population, according to a 2019 meta-analysis by Kinnaird, Stewart, and Tchanturia. And a 2013 study by Bird and Cook argued that much of what has been attributed to autism itself in the empathy conversation is actually the effect of alexithymia, which co-occurs with autism but is a separate phenomenon.
This article walks through what alexithymia actually is, why it shows up so often in autism, how it looks in children, what the empathy conversation should actually sound like, and what families can do.
What Alexithymia Actually Is
Alexithymia was named in 1973 by psychiatrist Peter Sifneos. The word is Greek: a- (without), lexi- (word), thymos (emotion). Literally: without words for emotions.
Alexithymia is not a mental illness or a personality disorder. It is a specific pattern involving three main features:
1. Difficulty identifying feelings. The person has trouble distinguishing between different emotional states in themselves. They may know something is happening internally but cannot tell whether it is anxiety, anger, sadness, hunger, or physical discomfort. The signals are there, but they are unlabeled.
2. Difficulty describing feelings to others. Even when the person recognizes that they are feeling something, they struggle to put it into words. The vocabulary is not available in the moment. When asked "how do you feel?", they may have no meaningful answer.
3. Externally-oriented thinking. The person's cognitive style tends to focus on external facts, tasks, and details rather than on their own internal emotional experience. Introspection is not their default.
These features exist on a spectrum. Some people have mild alexithymia and some have severe alexithymia. Some people can identify strong emotions but struggle with subtle ones. Some can recognize their emotions internally but cannot articulate them to others.
Alexithymia can be measured, most commonly with the Toronto Alexithymia Scale (TAS-20), a 20-item self-report questionnaire developed by Bagby, Parker, and Taylor in 1994. It is used across clinical settings and research contexts.
The Autism Connection
Alexithymia is not exclusive to autism. It occurs in eating disorders, depression, chronic illness, trauma histories, and in the general population at roughly 10% prevalence. But it is dramatically more common in autism.
Approximately 50% of autistic people meet alexithymia criteria (Kinnaird et al. 2019 meta-analysis)
Compared to roughly 10% of the general population
The pattern shows up across ages, gender, and support levels
This does not mean all autistic people have alexithymia. About half do, and about half do not. The half who do experience specific challenges that get frequently misattributed to autism itself. The half who do not experience emotions in ways that are often quite intense.
The Empathy Reframe (This Is the Main Point)
Here is the critical research finding that changes everything about the empathy conversation.
In a widely cited 2013 study, Geoff Bird and Richard Cook analyzed a large body of research that had claimed autistic people have empathy deficits, and demonstrated a specific pattern:
When researchers measured empathy in autistic and non-autistic groups without accounting for alexithymia, they found autism-linked "empathy deficits"
When researchers accounted for alexithymia (comparing autistic and non-autistic people with matched alexithymia levels), the autism-linked "empathy deficits" disappeared
In other words: much of what had been described as "autistic people lack empathy" was actually "people with alexithymia have measurable differences in emotional processing, and alexithymia happens to be more common in autistic populations."
Autistic people without alexithymia (the roughly 50% who do not have it) generally show typical or above-typical empathy on standard measures. Some studies suggest autistic people often experience hyper-empathy (intense emotional resonance, sometimes overwhelmingly so). What tends to differ across autistic and non-autistic populations is not the presence or intensity of empathy, but the way emotional information is processed, identified, and expressed.
The result: the "autistic people lack empathy" myth is largely a misattribution. The observed differences that gave rise to the myth are better explained by alexithymia, which is a different thing.
This matters because the myth causes real harm. Autistic children who are told they lack empathy grow up believing they are defective. Autistic adults are denied jobs, friendships, and relationships based on a widespread misreading of their emotional worlds. Reframing the science reframes the person.
Two Kinds of Empathy: Cognitive and Affective
To be fair to the empathy conversation, one specific distinction matters here. Empathy is often described in the psychology literature as having two components:
Cognitive empathy: the ability to understand what another person is thinking or feeling. Theory of mind. Perspective-taking.
Affective empathy: the actual felt experience of resonating with another person's emotional state.
Cognitive empathy in autism has been extensively studied and, for some autistic people, is genuinely different (though again, this varies by individual and by measurement method). Affective empathy in autism, when measured while accounting for alexithymia, generally is not different from non-autistic populations. In many cases it is higher.
So when someone says "autistic people lack empathy," the most accurate response might be: they may process information about other people's emotional states differently, and if they have co-occurring alexithymia they may have trouble identifying or expressing their own emotional states, but the felt experience of caring about others is not lower and is sometimes much higher.
What Alexithymia Can Look Like in Children
For families of autistic children, recognizing alexithymia is often the moment things start making sense. Some things that may be alexithymia in action:
Physical, not emotional, language for distress. The child says "my stomach hurts" when overwhelmed. They complain of headaches, tiredness, or vague body pain rather than saying "I feel anxious." The body is speaking because the vocabulary is not available.
Meltdowns that "come out of nowhere." From the outside, the meltdown seems sudden. From the inside, the child has been building up distress for hours or days without being able to identify or communicate it. When it finally emerges, it emerges as a crisis because it was never signaled earlier.
Delayed emotional processing. Something upsetting happens at 10am. The child seems fine at the time. At 6pm they fall apart. The delay is often the time needed to actually recognize what was felt.
Difficulty answering "how do you feel?" The child may repeatedly say "fine," "I don't know," or "I don't care." This is not evasion. The information may not be internally accessible.
Difficulty with "why" questions about behavior. "Why did you hit your sister?" "Why did you have a meltdown?" These questions require introspection into an emotional state that the child cannot easily access.
Confusing hunger, thirst, tiredness, and emotions. The child may not distinguish clearly between "I am hungry," "I am anxious," and "I need to leave this room." The signals feel similar and go unlabeled.
Flat or unexpected facial expression. The child's face may not match what they are feeling internally, either because they are not aware of the feeling or because the connection between internal state and external expression is different for them.
Intense reactions to others' emotions. Some children with alexithymia experience others' emotional states as overwhelming without being able to identify what they are experiencing themselves. They know something is happening but can't parse it.
This is not every autistic child. It is many, and recognizing when your child fits this pattern changes how you respond.
The Interoception Connection
Alexithymia is closely related to another concept that has become widely discussed in autism circles: interoception, the ability to sense internal body states. If you are unfamiliar with interoception, our interoception and autism guide covers it in depth.
The connection is direct. Emotions are, at the physiological level, patterns of internal body sensations. A racing heart. A knot in the stomach. Muscle tension. Flushed skin. If a person's interoception is different (weaker, delayed, harder to interpret), the raw material for emotional identification is different too. The emotion happens, but the person cannot easily read the signals.
This is why interoception work is often central to alexithymia support. Building the child's ability to notice and label internal body states creates the foundation for emotional identification later.
What Helps: Practical Strategies
Alexithymia is not something you fix. It is a way the person's emotional processing works, and much of the useful work is around building supports that make emotional information more accessible, not eliminating the alexithymia itself.
Emotion vocabulary building. Explicit teaching of emotion words, matched to real experiences. "That thing you are feeling right now, with the tight chest and the fast breathing, is often called anxiety." Naming, over time, builds the connection between internal state and language.
Body-based recognition first. Instead of asking "how do you feel?", ask "what does your body notice?" or "what's happening in your stomach right now?" Interoceptive language is often more accessible than emotional language, and translations can follow.
External labeling by trusted adults. Reflect back what you see. "It looks like your body is buzzing. That is sometimes what happens when you are excited or when you are anxious. Which one feels closer?" This is not putting words in the child's mouth; it is offering vocabulary the child can accept or reject.
Emotion charts, wheels, and pictures. Visual supports (like Plutchik's Wheel of Emotions, or simpler emotion charts scaled to the child's level) give the child options to choose from rather than requiring them to generate the word themselves.
Somatic awareness practice. Body scans, gentle noticing exercises, and interoception-focused work (increasingly used by occupational therapists) build the physical foundation for emotional recognition.
Reducing pressure to explain feelings. The chronic demand of "tell me how you feel" can actually make alexithymia worse by increasing anxiety around the question. Sometimes the most supportive thing is to stop asking and let the child experience the feeling without narrating it.
Written or drawn processing. Some children with alexithymia can access emotional information more easily through writing, drawing, or making things than through spoken conversation. Journaling, art, and creative expression can be alexithymia-friendly.
Trusted humans as emotional interpreters. Alexithymic children often rely on a small number of trusted adults who know them well enough to help them identify what they are feeling. This is not dependency. It is scaffolding, and it can be part of long-term support.
Time before response. After something emotional happens, the child may not know what they felt for hours. Building in time and space for delayed processing (without demanding immediate explanation) is often the difference between a productive conversation and a meltdown.
What Alexithymia Does Not Mean
Because alexithymia is often confused with things it is not, some clarifications:
Alexithymia does not mean the person does not feel emotions. The emotions are there. The identification and labeling is what is different.
Alexithymia does not mean the person does not care about others. Empathy and alexithymia are different constructs.
Alexithymia is not chosen. The person is not withholding, evading, or being difficult when they cannot answer emotional questions.
Alexithymia is not a moral failing. It is a neurologically-based pattern.
Alexithymia is not autism. They frequently co-occur but they are different, and each can exist without the other.
Alexithymia is not the same across the day. Emotions may be more or less identifiable depending on stress, sleep, sensory environment, and the specific emotion.
Why This Reframe Matters for the Whole Autism Conversation
The alexithymia research is one of the most significant reframes in autism science of the past decade. It has implications far beyond a single family's understanding of a child:
It corrects a persistent misunderstanding. The "autistic people lack empathy" myth has done enormous harm to autistic children and adults across generations. Naming it as misattribution shifts the conversation.
It refines what autism-specific supports should target. If a child has autism plus alexithymia, the support looks different from a child with autism who does not have alexithymia. Universal advice about "teaching empathy" misses the point.
It validates the internal experience of autistic people. Autistic advocates and self-advocates have been saying for decades that they feel deeply, and are simply expressing or processing feelings differently. The research now supports what they have been saying.
It reduces stigma. A child who understands that "I have trouble finding words for feelings, and that's called alexithymia, and it's separate from caring about people" carries a very different self-story than a child who has been told they lack empathy.
It informs how educators, therapists, and clinicians support autistic children. Practitioners who understand alexithymia offer meaningfully different, and often much more effective, emotional support than those who assume the "empathy deficit" model.
When to Seek Additional Support
Alexithymia itself is not typically treated as a disorder. But some situations warrant additional professional support:
Your child's difficulty identifying feelings is affecting relationships, school, or family life
Meltdowns are frequent and seem to come from nowhere (a common alexithymia pattern)
Your child seems disconnected from their own emotional experience in ways that concern you
Your child is experiencing co-occurring mental health challenges (anxiety, depression)
Your child is showing signs of internalizing distress that they cannot verbalize
Providers who tend to be helpful: occupational therapists with interoception training, autism-experienced psychologists, and mental health providers who understand the alexithymia-autism connection. A Board Certified Behavior Analyst (BCBA) can support the practical scaffolding side (emotion vocabulary building, communication systems, reducing pressure) alongside these other providers.
How Blossom ABA Supports Emotional Development
Blossom ABA works with autistic children and teens across Georgia, Tennessee, Virginia, North Carolina, and Maryland. Our Board Certified Behavior Analysts (BCBAs) approach emotional development with the assumption that every child's emotional processing is real and worth respecting, even when it does not match neurotypical patterns.
Where we can help:
Communication support that builds emotion vocabulary
Interoception-focused work in coordination with occupational therapy
Family coaching on how to support children who cannot easily name their emotions
Behavior support planning that accounts for alexithymia (understanding that meltdowns often reflect unnamed cumulative distress rather than sudden emotional dysregulation)
Coordination with schools on emotional accommodations
Referrals to occupational therapists and autism-experienced psychologists when additional support is needed
If your autistic child struggles with identifying or expressing their emotions, or if you have encountered the "empathy deficit" narrative and it did not match your child, contact our team. We can talk through what a coordinated approach might look like.

Frequently Asked Questions
1. What is alexithymia?
Alexithymia is a specific pattern involving three main features: difficulty identifying one's own feelings, difficulty describing them to others, and a cognitive style oriented toward external facts rather than internal emotional experience. The word is Greek and means "without words for emotions." Alexithymia was first named by psychiatrist Peter Sifneos in 1973 and is measured with tools like the Toronto Alexithymia Scale (TAS-20). It exists on a spectrum from mild to severe.
2. Do all autistic people have alexithymia?
No. Approximately 50% of autistic people meet criteria for alexithymia, compared to around 10% in the general population, according to a 2019 meta-analysis by Kinnaird, Stewart, and Tchanturia. About half of autistic people do not have alexithymia. This means alexithymia is common but not universal in autism, and treating them as the same thing produces inaccurate expectations.
3. Is alexithymia the same as lacking empathy?
No. This is one of the most important distinctions. Alexithymia is about difficulty identifying and describing one's own emotions. Empathy is about resonating with and understanding other people's emotions. They are separate constructs. Research by Bird and Cook (2013) showed that much of what has been described as "autistic empathy deficits" is actually the effect of co-occurring alexithymia, not autism itself. Autistic people without alexithymia generally show typical or above-typical empathy on standard measures.
4. Can autistic children with alexithymia care about other people?
Yes. Caring about others is a matter of empathy, and empathy is not what alexithymia affects. Autistic children with alexithymia often care deeply about others. What they may struggle with is identifying and expressing what they are feeling in response. The internal caring is there. The vocabulary and expression may not be, or may show up differently from what an observer expects.
5. What does alexithymia look like in children?
Common patterns include: describing distress in physical rather than emotional terms ("my stomach hurts" instead of "I'm anxious"), meltdowns that seem to come from nowhere (because distress accumulated without being identified), delayed emotional processing, difficulty answering "how do you feel?", confusing hunger, thirst, tiredness, and emotions, and flat or unexpected facial expressions. Not every autistic child fits this pattern, but many do.
6. What can families do to help?
Build emotion vocabulary explicitly by naming emotions in real moments. Ask about body sensations before asking about emotions. Offer visual supports like emotion charts. Reduce pressure to explain feelings on demand. Support delayed emotional processing (some children need hours or a day to know what they felt). Use writing, drawing, or making as alternative processing modes. And recognize that alexithymia is a pattern to accommodate, not a deficit to fix.
7. Is alexithymia caused by autism?
Alexithymia is not caused by autism, though it commonly co-occurs with autism. It also occurs in eating disorders, depression, chronic illness, trauma histories, and in the general population. In autism, the co-occurrence rate is significantly higher, and researchers are still exploring why. What matters practically is that alexithymia is a distinct pattern that can be identified and supported, separate from autism itself.
8. Can alexithymia change over time?
Yes, to some degree. While alexithymia tends to be a stable trait, the vocabulary and scaffolding around it can grow over time. Many autistic adults with alexithymia have developed sophisticated systems for identifying their emotions through body sensations, delayed reflection, or external processing (like journaling or talking through experiences). Children who receive alexithymia-informed support often build these skills more efficiently than those who do not.
