This book examines the role of interlocutors and their individual differences (IDs) in second language (L2) development from four theoretical lenses: the cognitive-interactionist approach, sociocultural theory, the variationist approach, and complex dynamic systems theory. A theoretical overview to each approach is written by a preeminent scholar in the framework, and each overview is followed by an empirical study that demonstrates how interlocutor IDs can be fruitfully researched within that framework. To maximize readability and impact, the chapters follow common organizing questions, inviting the engagement of L2 researchers, students, and teachers alike.
