Two experiments using the picture-word interference paradigm were used to investigate the nature of the representations (phonological/orthographic) underlying lexical access, both in picture naming and in picture writing, and their activation time course. Three alternative views of lexical access in naming and in writing were tested. According to the first view, phonological and orthographic codes are activated in parallel both in writing and in naming. According to the second view, phonological codes are only activated in naming and orthographic codes are only activated in writing. Finally, the third view states that phonological codes are activated in naming and mediate writing. The findings did not support one of three tested views on lexical access in naming and in writing. However, they clearly ruled out a strict phonological mediation view of lexical access in writing.
