Unlike speech production, lexical access in written production has not systematically been investigated experimentally. Four experiments were run on literate adults to support the view that although the spoken and written language production systems may obviously share some processing levels, they also both have some speci® c processing components. The general ® ndings provide evidence for such a view and are discussed in the framework of studies in verbal production conducted on normals and on braindamaged patients.
