People are increasingly reaching the so-called third age, a period when seniors search for a renewed purpose to life and spend time undertaking activities that they consider motivating, such as the learning of a foreign language. The study of language learning among aging populations has become a fast-growing area of research and this book is one of the first attempts to bring together what we know about this age group and their profiles as foreign language learners. Contributors to the volume discuss the issue from various psychological, neurological and pedagogical perspectives. Each of the chapters provides an updated theoretical background and offers some initial conclusions on the basis of original empirical studies carried out. Chapters challenge certain familiar preconceptions and assumptions about senior learners, offer the reader ideas for future research in this under-studied area and provide some practical advice for applying the proposals and solutions offered in real foreign language third-age classrooms.
