Although it is commonly believed that language and culture are inexorably linked, the precise nature of this relationship remains elusive. This study investigated the hypothesis that a loss in language signals a loss in culture if language is considered a central value. This hypothesis was investigated by rating the Hindi and English proficiency of 30 first and second generation Indo-Canadian Hindi speakers (15 parent-child pairs) and relating these to their reactions in a matched-guise task, featuring culturally charged English and Hindi scenarios recorded by the same speaker. The scenarios targeted one aspect of North Indian culture--the value of filial duty--in two contexts (marriage, career). It was hypothesised that, if language loss triggered culture loss, then speakers losing their Hindi (second generation), but not those maintaining it (first generation), would differ in their reactions to scenarios as a function of language. Findings revealed a language shift and the beginnings of a culture shift between the two generations. However, the shift in culture appeared not to be mediated by language. Implications of these findings for heritage language and culture maintenance, the language-culture relationship and group identity construction are discussed. (Contains 4 tables.)
