Processing Instruction: Theory, Research, and Commentary presents ten previously unpublished articles that update and illustrate the influence of the input processing model on processing instruction in second language acquisition.

Each section of the volume offers commentaries from renowned researchers in instructed second language acquisitions, including critical perspectives on various points of PI research. The empirical chapters within the sections address theoretical and pedagogical issues such as processing instruction vs. other types of instruction; the impact of processing instruction on various linguistic structures; the role of explicit information in instructional intervention; and the long-term effects of processing instruction. In addition to providing further research and commentary on PI, this volume will be an important resource for graduate students and researchers regarding research methodology and replication in second language acquisition and language teaching.
