Introduction to Volume 2 Constraining Binding, Dependencies, and Learnability: Principles or Parameters?
Pages 37

One of the most active areas in the study of Universal Grammar during the last decade has centered around a universal theory of various forms of syntactic dependencies, specifically, both A and A' (argument and nonargument) dependencies. Intensive research has concerned both lexical proforms and empty categories. Cross-linguistic investigation into this area of UG has led to a wide set of discoveries about natural language variation and has raised fundamental issues about its proper representation in formal theory. As the chapters in this volume document, these theoretical issues are closely paralleled by issues in first language acquisition.
