Why Is Understanding Metaphors Related to Emotions Challenging for Individuals with Autism?
Emotional metaphors like “broken heart,” “boiling with anger,” or “green with envy” rely on abstract, non-literal meaning. According to NHS guidance, many autistic people interpret language literally and can find figurative or metaphorical expressions hard to follow, especially in group settings where cues shift quickly. This reflects differences in how language, context, and emotion are processed and integrated.
Why Figurative Emotional Language Is Harder
NICE guidance (CG142) notes that autistic adults often experience persistent difficulties understanding non-literal language such as jokes, irony, and metaphors, especially in unfamiliar situations. Structured, explicit teaching and communication supports are recommended. The National Autistic Society (NAS) add that visual teaching, written instructions, and repetition help autistic people interpret idioms and metaphors more confidently.
What the Research Shows
Neuroimaging studies show that autistic individuals process figurative and emotional language differently. A 2022 article in Frontiers in Communication reviewed behavioural and brain-based research on figurative language comprehension in autism and found that literal language preferences and pragmatic communication differences make emotional and non-literal meanings harder to infer. Additional research indicates that pragmatic language interventions and structured language teaching can improve comprehension by explicitly linking emotional states with metaphorical expressions. The WHO ICD-11 also recognises difficulty with figurative and emotional language as part of the diagnostic description of autism’s social-communication profile.
Practical Supports That Help
Evidence-based supports include speech and language therapy focused on pragmatic communication, explicit metaphor teaching using visuals and examples, and practice identifying emotional cues in conversation. These strategies align with NHS and NICE advice and have been shown to strengthen language flexibility and social understanding.
Takeaway
Struggling with emotional metaphors reflects a difference in social-emotional and linguistic processing, not a lack of empathy. With structured communication programs, visual tools, and practice, many autistic people can build confidence interpreting figurative expressions and expressing feelings more clearly.
