ABSTRACT
The work upon which the present report is based was designed to integrate those aspects of bilingual behaviour which had previously been studied separately. A variety of linguistic, psychological, and sociological measurements of bilingual behaviour were designed for use in a study of Puerto Ricans in Greater New York. Bilingual census-takers asked a representative from each household to respond to a series of questions about himself and about the other members of the household. A variety of techniques for the measurement and description of bilingualism, derived separately from the disciplines of linguistics, psychology, and sociology, were administered to the same respondents, forty-eight Spanish-English bilinguals who lived in a Puerto Rican neighbourhood near New York, in order to assess the relationships among these measures and their relative utility as predictors of four proficiency criterion variables.
