It is often assumed that metalinguistic performance (e.g., detection of
ambiguity, judgments of grammaticality) straightforwardly reflects
linguistic knowledge. The inadequacies of such an assumption are
explored in this volume, which documents the subtleties of the
relationship between metalinguistic performance and knowledge of a
second language (interlinguistic competence) from the perspectives of
language acquisition theory and cognitive and developmental psychology.
This thorough and up-to-date examination of metalinguistic phenomena
offers insight to those involved in designing elicitation materials,
analyzing and interpreting metalinguistic performance data, and applying
such evidence to descriptions of interlanguage grammars and to
second-language acquisition theory. The book also contributes
constructively to the current debate concerning the role of
metalinguistic variables in second-language acquisition, that is, how
they ultimately affect success or failure in learning a second language.
