de Bot, K., & Makoni, S. (2005). Language and Aging in Multilingual Contexts. Bristol, UK: Multilingual Matters.
In this book different aspects of language and aging are discussed. While language spoken by and language spoken with elderly people have been treated as different areas of research, it is argued here that from a dynamical system perspective the two are closely interrelated. In addition to overviews of research on language and aging, a number of projects on this topic in multilingual settings are presented.
