For many people, learning a second language as an adult is a challenging endeavor. Much interest in the study of adult second language learning has concerned the type of input that learners receive in their second language, with findings suggesting that second language learners are often exposed to a register of speech called 'foreigner talk' that…

This study tests the Competing Systems Hypothesis (CSH) as applied to adult second language acquisition of aspect in Spanish. The CSH purports that differences among tutored and untutored learners result from competition between one system of underlying grammatical knowledge and another of learned metalinguistic knowledge in tutored learners…

Individual differences (IDs) largely contribute to success in adult second language attainment (e.g., Dörnyei, 2006). Heritage language (HL) studies have also explored the role of IDs, namely psychosocial variables, and biographical factors with an adult HL learner population. However, the specific contribution of these variables to HL learners'…

This article presents the results of experimental data on language production and comprehension. These show that adult learners of Dutch as an additional language, with different language backgrounds, and a L2 proficiency below level A2 (Waystage) of the Common European Framework of Reference for Languages (CEFR; Council of Europe, 2001), use…

Second language (L2) learners have been found to experience difficulty in tasks that require the integration of discourse-pragmatic properties with syntactic and semantic properties (Sorace and Serratrice, 2009; Tsimpli and Sorace, 2006; Valenzuela, 2006). The present article investigates the sources of L2 difficulty in a phenomenon where multiple…

This study examines whether adult second language (L2) learners of an ungendered first language (L1) are sensitive to gender congruency (grammatical feature absent in the L1) and noun animacy (semantic feature present in the L1) when processing L2 gender concord and whether L2 proficiency level determines such sensitivity. To address these…

Second language acquisition studies can contribute to the body of research on the influence of language on thought by examining cognitive change as a result of second language learning. We conducted a longitudinal study that examined how the acquisition of Spanish grammatical gender influences categorization in native English-speaking adults. We…

This study examines the associations between the speaking proficiency of 181 adult learners of Dutch as a second language and their linguistic competences. Performance in eight speaking tasks was rated on a scale of communicative adequacy. After extrapolation of these ratings to the Overall Oral Production scale of the Common European Framework of…

This article presents a selective overview of studies that have investigated how advanced adult second language (L2) learners process morphologically complex words. The studies reported here have used different kinds of experimental tasks (including speeded grammaticality judgments, lexical decision, and priming) to examine three domains of…

Tasks have received increased attention in SLA research for the past decade, as has the role of focus on form. However, few empirical studies have investigated the relationship among tasks, focus-on-form techniques, and second language (L2) learning outcomes. To help address this gap, the present study examined how the task variable +/- contextual…

Investigated the talk of 14 intermediate learners of English as a Second Language in a tertiary setting as they performed a passage-editing task collaboratively. Transcripts of the students' dialogs were analyzed for the kind of talk the task elicited, the grammatical items that drew the most attention from the learners, and the knowledge sources…
