One of the most intriguing questions in the investigation of second-language acquisition concerns the role of learners' first language (L1). Comparing learners of different backgrounds (L1 German vs. L1 Romance languages), we aim to explore the acquisition of tense and aspect features in Spanish as a second language (L2). Findings show that the L1…

Collaborative writing tasks have been claimed to offer language learning opportunities because they implicitly draw learners' attention to form. Nevertheless, their efficacy has been claimed to be moderated by proficiency, as low proficiency learners tend to override form over meaning. These claims, however, are mostly based on adult learners and…

This study examines the extent to which extra-linguistic factors such as language dominance, order of acquisition and language of instruction are deterministic for multilingual transfer selection and subsequent development. We test two groups of Catalan-Spanish bilinguals acquiring English as an L3 in a controlled setting. We first examine…

Considering the acquisition of past tense uses by L2 Spanish advanced learners with closely related L1s (French, Portuguese), this study attempts to identify factors associated with variability, such as negative transfer or interface integration. We report data on the acquisition, by adult L1 French and Portuguese learners at B2 and C1 CEFR…

This article reports on a study investigating the relative influence of the first language and dominant language (L1) on second language (L2) and third language (L3) morpho-lexical processing. A lexical decision task compared the responses to English NV-er compounds (e.g. "taxi driver") and non-compounds provided by a group of native…
