Elaine Francis, Professor, Department of English, Purdue University

Elaine J. Francis is a professor in the Department of English at Purdue University, where she has been teaching linguistics and directing the Experimental Linguistics Lab since 2003. She completed her PhD in linguistics at the University of Chicago in 1999 and taught for three years in the Department of English at the University of Hong Kong. In her research, she investigates syntactic, discourse, and processing-based factors that affect the realization of syntactic alternations in English and Cantonese.

"The greatest strength of Francis' book lies in the author's meticulous and nuanced interpretations of a broad range of experimental results. These discussions not only illustrate the value of good scientific practice, but they also highlight how difficult it is to derive conclusive interpretations about the factors that give rise to acceptability judgments." -- Tobias Ungerer, Journal of English Language and Linguistics

"The book bridges the interests of theoretical linguistics in the field of syntax, experimental syntax, and related aspects in the psychology of language [...] All in all, this book is a must for future work on acceptability judgments for the complete overview it offers, the well-reasoned argumentation, and the author's own claims on gradience and soft constraints to capture the wide range of linguistic factors that can affect judgments on a gradient scale." -- Caterina Cacioli, Università degli Studi di Firenze, LINGUISTList

"The question that runs through the entire book can be summarized as follows: how can we interpret the judgments that speakers make about the acceptability of sentences of their language in relation to the theories held by the linguists who analyze them? That question involves one aspect that is often not made explicit: the interpretation of any data is conditioned by commitments and theoretical assumptions, both epistemological and methodological. The explanation of and reflection on this key point for any scientific field is one of the central axes of this book, making it essential reading." -- Gabriela Mariel Zunino, Cuadernos de Lingüística de El Colegio de México

"This book is a truly far-reaching, relevant piece of work. In addition to a comprehensive discussion on gradient acceptability judgments, it also presents an overview of current theoretical approaches and possible limitations they might exhibit in interpreting gradient judgments. One of the truly remarkable achievements of this book is the way in which Francis critically discusses the differences between the current theoretical approaches, but at the same time, brings together ideas from different linguistic schools of thought - which is certainly not an easy task to undertake." -- Ana Werkmann Horvat, Jezikoslovjle

"Francis tackles head-on deep methodological questions about the nature of linguistic data, and shows that modern linguistic research demands a more systematic exploration of variation and gradient acceptability; one that takes non-syntactic factors into account, uses converging evidence from alternative data sources, and re-assesses its own theory-internal assumptions. In the process, Francis uncovers compelling evidence that some forms of gradience call for non-categorical grammatical constraints ('soft constraints'), which cannot be reduced to non-syntactic factors nor categorical grammar constraints." -- Rui P. Chaves, University at Buffalo, the State University of New York

"Elaine Francis' book is compelling reading as it addresses a complex topic with fundamental relevance to all grammatical descriptions and theories. Francis makes a convincing case for gradience in grammar and for a multi-methodological approach to assessing language data. It is a comprehensive and principled synthesis of the literature enriched by the author's own research." -- Edith Moravcsik, University of Wisconsin-Milwaukee
