Motivations - both conscious and unconscious - are central to all forms of learning, including second language acquisition. Therefore, it is important for both researchers and language teachers to understand them. This study is the first to investigate the complex motivational processes in early, migration-related second language acquisition in all their breadth within the framework of current research. It is based on both applied and theoretical research interests in motivations and their effects. Carefully and thoroughly analyzed subjective data are related to objective data, making this work a substantial contribution to both practice and theory.
