Semantic conflicts are resolved differently by adults with and without ADHD.
Adults with ADHD need stronger word banks, not attention drills, to untangle metaphor-literal mix-ups.
01Research in Context
What this study did
Segal et al. (2015) compared adults with ADHD to adults without it.
They asked both groups to judge metaphor and literal sentences while timing speed and accuracy.
The goal was to see who got tripped up when the two meanings clashed.
What they found
Adults with ADHD solved the conflicts more slowly and made more errors.
Their success hinged on how many words they could quickly name, not on classic attention scores.
Controls leaned on attention control instead.
How this fits with other research
Miranda et al. (2013) saw the same group lag in story writing, and Martinussen et al. (2015) found teens with ADHD reading below peers—both link the trouble to weak vocabulary.
Caillies et al. (2014) showed kids with ADHD also miss irony, so the figurative-language gap starts early and lasts.
Lancioni et al. (2009) looked worse on attention tests, but their adults also had mild ID; once you account for the extra diagnosis the results line up rather than clash.
Why it matters
If you test an adult with ADHD, do not assume slow answers mean poor focus. Check rapid naming and semantic fluency first. When you teach social or reading skills, pre-teach key vocabulary and use clear literal cues before introducing metaphors, jokes, or abstract text. This small shift can cut both assessment errors and client frustration.

03Original abstract
Attention Deficit/Hyperactivity Disorder (ADHD) is a common neurobehavioral disorder characterized by various behavioral and cognitive difficulties. Previous studies indicated that children with ADHD have language difficulties, including difficulties in metaphor understanding but the relation between metaphor processing and specific cognitive functions needs further investigation. In the current study we examined how adults with and without ADHD resolve semantic conflicts between a metaphorical prime and a metaphorical or literal target sentence. Twenty-six adults with ADHD and 24 age-matched control participants underwent a thorough evaluation of neuropsychological skills, as well as assessment of various aspects of attention. Results suggested that people with ADHD were less efficient than controls in resolving conflicts between metaphorical and literal meanings of sentence pairs. In addition they showed deficient sustained attention and executive attention. Moreover, the ability to resolve semantic conflicts was related to semantic fluency in the ADHD group, but to executive attention in the control group. These findings emphasize the various specific difficulties of adults with ADHD and shed light on the different role of attention in the resolution of semantic conflicts among ADHD individuals as compared to controls.
