Many autistic individuals find that abstract or figurative instructions like “keep your eyes peeled” or “think outside the box” can be confusing. According to NHS guidance, autistic people often interpret language literally, meaning they process words exactly as spoken rather than searching for hidden or metaphorical meaning. This difference is not a sign of lower intelligence, but rather a unique cognitive style that affects how language and context are integrated.

What the research shows

Recent studies have explored why abstract or figurative language is more challenging for autistic individuals. A 2024 review in Autism Research found that autistic adults and children experience greater difficulty interpreting figurative expressions, such as idioms and metaphors, due to differences in cognitive flexibility and semantic integration (https://pubmed.ncbi.nlm.nih.gov/38071498/).

Brain imaging studies show that autistic people may recruit additional neural resources when processing abstract meaning. A 2025 Autism Research study found increased brain activity in areas linked to pragmatic language when autistic children tried to understand nonliteral phrases, reflecting the extra effort required.
Another experiment found that even verbally able autistic children struggled to both understand and create metaphors, suggesting that abstract language challenges persist beyond basic comprehension (https://pubmed.ncbi.nlm.nih.gov/39126199/).

A broader 2025 review in the Journal of Autism and Developmental Disorders linked these differences to predictive processing the ability to anticipate meaning from context. Autistic individuals may find it harder to predict or infer what is meant when instructions are vague or implied.

Guidance for clearer communication

Professional guidance emphasises the need for direct, concrete communication. NICE advises teachers and clinicians to use clear and structured language, avoiding metaphorical or abstract phrasing that could cause confusion.
The National Autistic Society similarly recommends specific, unambiguous instructions and visual aids to reinforce understanding.

By adapting how we communicate using plain, literal language and confirming understanding we help autistic individuals feel more confident and included in learning and social environments.

Takeaway

Understanding abstract instructions requires social, linguistic, and cognitive interpretation, all of which work differently in autism. When families, educators, and clinicians adjust communication styles to be clear, literal, and predictable, everyday interactions become less stressful and far more effective.
