People with aphasia show significant shape iconicity for rounded versus pointed auditory pseudowords, with ratings correlating with both predicted values and neurologically intact listeners.
- Why it matters: It is unclear whether speech sound–shape mappings survive in aphasia and how phonological and semantic impairments affect sensitivity to iconicity.
- What they did: Twelve individuals with aphasia and twelve age- and gender-matched neurologically intact participants rated 50 auditory pseudowords on a 5-point rounded–pointed scale; aphasia ratings were compared to predicted ratings and correlated with phonological and semantic measures.
- The result: Aphasia ratings correlated significantly with predicted and intact-participant ratings, but correlations with predicted values were weaker; greater language impairment, especially phonological segmentation and semantic processing deficits, was linked to reduced sensitivity to shape iconicity.
