This volume therefore looks at different language processing domains, such as speaking, listening, reading, as well as discourse and text processing, to evaluate the role attention plays in such performances; and also at how often linguistic inputs affect attentional processing. In this sense, it proposes that the attention--language interface is bidirectional. It also considers applied issues like language disorders, bilingualism and illiteracy, where the attention--language interface seems especially relevant as a theoretical apparatus for research investigations. Therefore, this volume brings closer theoretical explanations from the language sciences and cognitive sciences. It argues that language processing is multi-modal in its very essence and many conceptual structures in language evolve out of a complex interplay among participating cognitive systems such as attention and memory, supported by vision and audition.
