Research Methods in Sign Language Studies is a landmark work on sign language research, which spans the fields of linguistics, experimental and developmental psychology, brain research, and language assessment. It summarizes all relevant methodologies in sign language research and provides a detailed synopsis of how to do necessary research. In 20 chapters, it examines a broad range of topics, including ethical and political issues, key methodologies, and the collection of linguistic, cognitive, neuroscientific, and neuropsychological data. Each chapter is written by a top researcher on the subject and provides tips and recommendations to improve research quality at all levels. The book is innovative and contemporary in tone and ideology. It encourages readers to approach sign languages from the perspective of diversity rather than disability and is the first volume to bring together work focusing on methodology from both hearing and deaf researchers in sign language studies. Integrating research on sign languages from Europe, Asia, North and South America, and Africa, this is an essential reference for any student or researcher who requires the most comprehensive and up-to-date information in the field.
