This book is intended as an edited collection of empirical papers as well as secondary research papers that explore the recent trends and perspectives with regard to significant components of Positive Psychology (PosPsy) such as L2 grit, language learning enjoyment, well-being, happiness, or emotions. PosPsy has received remarkable attention from the L2 research community over the last decade. We believe that the chapters in this book will enable researchers to get an overall understanding of the PosPsy components in the Turkish context and provide inspiration for researchers who have a keen interest in PosPsy.
