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. In addition, the effects of language aptitude on input processing are considered. Further studies consider the contribution that interaction makes to the acquisition of grammatical knowledge. These studies provide clear evidence that social and intermental interaction are major forces in the acquisition of an L2. Finally, the book, considers a number of pedagogic specifications. In particular, the importance of discourse control as a means of learners’ obtaining the quality of interaction likely to foster acquisition is discussed. 17 12 15 1999 10 21 2008 9789027241245 9781556197369 9789027241252 9781556197376 9789027298874 John Benjamins Publishing Company Amsterdam 10.1075/sibil.17 http://www.jbe-platform.com/content/books/9789027298874 https://www.jbe-platform.com/deliver/fulltext/9789027298874.pdf https://www.degruyter.com/document/doi/10.1075/sibil.17/html
