Can an early learned second language influence speech production after living many years in an exclusively monolingual environment? To address this issue, we investigated the consequences of discontinued early bilingualism in heritage speakers who moved abroad and switched language dominance from the second to the primary learned language.

We examined negative transfer from English and Spanish to Portuguese pronunciation. Participants were native English speakers, some of whom spoke Spanish. Participants completed a computer-based Portuguese pronunciation tutorial and then pronounced trained letter-to-sound correspondences in unfamiliar Portuguese words; some shared orthographic…

A study of English speakers' acquisition of relative clauses in Chinese, Japanese, Persian, German, and Portugese is reported. Various structures were tested to separate interlanguage features attributable to first language interference from those universal to second language acquisition. Application of an accessibility hierarchy theory and…
