This book examines different theoretical perspectives on the role that interaction plays in second language acquisition. The principal perspectives are those afforded by the Interaction Hypothesis, Socio-Cultural Theory and the Levels of Processing model. Interaction is, therefore, defined broadly; it is seen as involving both intermental and intramental activity. The theoretical perspectives are explored empirically in a series of studies which investigate the relationship between aspects of interaction and second language acquisition. A number of these studies consider the effects of interaction on the acquisition of vocabulary (word meanings) by both adult and child L2 learners.

The importance of emotion in everyday interactions has become a central topic of research in a wide variety of disciplines, including linguistics, sociology, social psychology, anthropology, and communication. Emotion in Interaction offers a collection of original studies that explore emotion in naturally occurring spoken interaction. The articles examine both the verbal and non-verbal resources for expressing emotional stance (lexicon, syntax, prosody, laughter, crying, facial expression), the emotional aspects of action sequences

Prosody is constitutive for spoken interaction. In more than 25 years, its study has grown into a full-fledged and very productive field with a sound catalogue of research methods and principles. This volume presents the state of the art, illustrates current research trends and uncovers potential directions for future research. It will therefore be of major interest to everyone studying spoken interaction. The collection brings together an impressive range of internationally renowned scholars from different, yet closely related and compatible research traditions which have made a significant contribution to the field.

Social context, an often-neglected dimension in L2 learning/use, can play a vital role in sustaining learners' initial motivation. Using data on Welsh learners' experiences outside the classroom, the author argues that, to learn a foreign language, learners require regular interaction in the target language in a setting where they are comfortable.

This volume in honor of Susan M. Gass focuses on interaction in second language acquisition from multiple perspectives. International experts in the field of SLA contribute insights and explanations on the interaction approach's compatibility with other theoretical approaches, key empirical studies, interaction in specific contexts, and future directions. Readers will find an enriching discussion of how the interaction research tradition is viewed in a wide range of different appraoches to learning and teaching second languages.
