Inner speech has been a focus of multidisciplinary interest. It is a long-standing phenomenon of study in philosophy, psychology, and anthropology. Researchers from different disciplines have turned their efforts to understand this inherent experience of being 'talking to oneself'. In psychology, Vygotsky managed to develop a complete description of the phenomenon, giving rise to a great line of research related to inner speech in the human experience.

Including a compilation of theoretical and empirical advances related to inner speech phenomenon, this book is aimed at academics and researchers in the area of psychology, education and culture. This book will be of interest to international research programs, related to cultural psychology, socio-constructivism, developmental psychology and education.
