Abstract:
The ability to understand speech in one's native language is considered universal. This assumption implies that literate and illiterate people recognize spoken words in the same way. Our study provides new neurophysiological evidence against this assertion, showing that the speech representations stored in the “phonological” lexicon of literate people are contaminated by orthographic features. This observation calls into question the universality of spoken word recognition models that have been built exclusively on the basis of results obtained from literate participants.
