Investigators of first language attrition, early bilingualism and child second language learning have found common ground on a number of important points. The present review of the research will show that the study of unevenness in the early development of two languages reveals more clearly how the critical problems for future research on…

Studies are reported which support the hypothesis that there is a "critical period" for the complete and natural acquisition of language extending from about age two to puberty, and which indicate that the critical period is also relevant for dialect learning. (Author/RM)

Discusses how current applied and sociolinguistic research and theory, which reveals the naturalness of language variation and productive aspects of error-making, seriously challenges traditional second language learning practices and postulates. (EKN)
