Lexical ambiguity is one of the major themes in psycholinguistic research over the past two decades. The purpose of this paper is to review the advances and issues in lexical ambiguity research after mid-80s. The central topic in this area is context effects on disambiguation processes. Using crossmodal priming paradigm and other experimental methods, psychologists have studied the on-line processes of resolving lexical ambiguity. Although multiple access model and selective access model are traditionally two major models, hybrid models which include activation of multiple meanings, context-sensitivity, and frequency-dependency are needed, and connectionism is a promising framework. We also examine findings about processing of isolated ambiguous words. Although work on lexical ambiguity has focused more on processing, we must also study the structure and learning mechanism of ambiguity itself.
