The book deals with the interplay of cognitive, emotional, and motivational factors in developing oral competence in German as a tertiary language among adult Italians. It relies on an interdisciplinary approach that is theoretically discussed and elaborated in detail regarding its methodological choices, particularly videography as well as intro- and retrospective methods. The results of the study illustrate the learning processes across classes, while also providing a detailed analysis of individual learners. The bibliography offers educators, students, and researchers a comprehensive bibliographic resource on the topics addressed.
