ROLE OF PHONOLOGICAL AND ORTHOGRAPHIC CODES IN PICTURE NAMING AND WRITING - AN INTERFERENCE PARADIGM STUDY

Two experiments using the picture-word interference paradigm were used to investigate the nature of the representations (phonological/orthog raphic) underlying lexical access, both in picture naming and in pictu re writing, and their activation time course. Three alternative views of lexical access in naming and in writing were tested. According to t he first view, phonological and orthographic codes are activated in pa rallel both in writing and in naming. According to the second view, ph onological codes are only activated in naming and orthographic codes a re only activated in writing. Finally, the third view states that phon ological codes are activated in naming and mediate writing. The findin gs did not support one of three tested views on lexical access in nami ng and in writing. However, they clearly ruled out a strict phonologic al mediation view of lexical access in writing.
