This book contains papers that were written to honor Professor Lyn Frazier on the occasion of her retirement from the University of Massachusetts Amherst. Some were presented at the Lynschrift on May 19-20, 2018; others were written especially for this volume. The papers report original research on, or research-based theoretical analyses of, several of the domains that Professor Frazier contributed to during her career. The volume begins with a brief overview of Professor Frazier's research contributions and an appreciation of the contributions she has made to the field of psycholinguistics and to her students and colleagues. The next several chapters discuss the roles that prosody plays in language processing, and the volume continues with chapters on the topic that established Professor Frazier as a major psycholinguistic theorist, syntactic processing. The volume then explores the roles semantics and pragmatics play in language comprehension, and concludes with reports of applications and extensions of research on language processing. All chapters were contributed by current and former students and colleagues of Professor Frazier in gratitude for the impact she has had on their lives and careers.
