How Literal Thinking Impacts Understanding Abstract Health Concepts in Autism
Many autistic people process information literally, focusing on the precise meaning of words rather than implied or abstract concepts. According to NHS guidance, this can make common health messages such as “eat healthy,” “manage stress,” or “take care of yourself” difficult to interpret. These phrases are often too general or metaphorical to provide clear, actionable meaning without examples.
Literal thinking is not a weakness but a different cognitive processing style. While many people infer meaning from context, autistic individuals tend to rely on direct, explicit information. When health communication uses vague or figurative language, it can leave gaps in understanding that affect daily wellbeing and self-care.
What the evidence shows
Recent studies highlight that literal interpretation affects how autistic individuals understand health information. The National Autistic Society explains that figurative or abstract language often causes confusion unless supported with clear, step-by-step explanations.
A 2025 qualitative study of clinicians found that healthcare professionals recognised the need to simplify and clarify health instructions for autistic patients who interpret general advice literally. Similarly, a 2022 review in Frontiers in Communication showed that autistic individuals process figurative language more slowly and less accurately, which can affect understanding of abstract health or wellbeing advice.
Guidance from NICE recommends using unambiguous, concrete language when discussing wellbeing or lifestyle advice with autistic adults, to ensure accurate comprehension. The Autistica UK project on social prescribing also found that abstract advice such as “stay active” is better understood when converted into specific, structured examples, like “go for a short walk three times a week.”
Making health communication more accessible
For autistic people, abstract concepts like “healthy living” or “stress management” need to be translated into concrete, achievable actions. For example:
- Instead of “eat healthy,” say “include two servings of vegetables with lunch and dinner.”
- Replace “reduce stress” with “take a five-minute break when you feel overwhelmed.”
- Clarify “stay active” as “try a short walk after meals.”
These strategies help make health guidance meaningful, practical, and inclusive.
Takeaway
Literal thinking means that autistic individuals may need clearer, more specific health communication to understand and act on wellbeing advice. By adapting how information is presented, healthcare professionals and families can make health education more accessible and empowering.
