The works in this volume are based on a truly provocative assumption?that to properly understand the mental lexicon, bilingualism is the correct default context for studying it. For this reason alone, this collection makes a significant contribution. The chapters, all written by leading researchers, provide thorough and compelling analyses, and touch on a comprehensive range of ways to think about the dynamic and integrated nature of the mental lexicon. Graduate students and seasoned researchers alike will profit from the wealth of ideas in this volume. This is a must-have reference for all mental lexicon theorists and researchers. -- Prof. Norman Segalowitz, Concordia University (Montreal)
