Chapter 1
The problematic pursuit of defining advancedness
The introductory chapter establishes the need for the
present volume by providing an overview of the main foci of previous
research in SLA examining advanced proficiency, and by identifying various
lacunae in the data base of what we know. We provide a description of the
volume’s structure, explaining the rationale for each of the four sections,
and we introduce the main topics and aims of each chapter.
