1 Accessing words in speech production: Stages, processes and representations*

This paper introduces a special issue of Cognition on lexical access in speech production. Over the last quarter century, the psycholinguistic study of speaking. and in particular of accessing words in speech, received a major new impetus from the analysis of speech errors, dysfluencies and hesitations, from aphasiology. and from new paradigms in reaction time research. The emerging theoretical picture partitions the accessing process into two subprocesses. the selection of an appropri-ate lexical item (a "lemma") from the mental lexicon, and the phonological encoding of that item, that is, the computation of a phonetic program for the item in the context of utterance. These two theoretical domains are successively introduced by outlining some core issues that have been or still have to be addressed. The final section discusses the controversial question whether phonological encoding can affect lexical selection. This partitioning is also followed in this special issue as a whole. There are, first, four papers on lexical selection, then three papers on phonological encoding, and finallv one on the interaction between selection and phonological encoding. Issues of lexical access How do we access words when we speak? This question has not received serious scrutiny until relatively recently. But as soon as it was asked, a whole range of issues emerged. *I am grateful to Aditi Lahiri for her important remarks on syllable representation and th
