This special issue shows how accessibility phenomena need to be studied from a linguistic and psycholinguistic angle, and in the latter case from interpretation, as well as production. The contributions augment the growing knowledge of accessibility in text and discourse processing. They also illuminate how accessibility is marked in a text or a discourse, how readers and listeners respond to those markings, and how mental representations evolve and change as a direct result of accessibility. The editors hope is that the text affects the readers' representations in ways that linguists and psycholinguists theorize as beneficial.
