Successful language learning in bilinguals requires the differentiation of two language systems. The capacity to discriminate rhythmically close languages has been reported in 4-month-olds using auditory-only stimuli. This research offers a novel perspective on early language discrimination using audiovisual material. Monolingual and bilingual…

If maximal exposure were the key to success in language learning, then adult learners at the university level would be doomed to fail. Not only are they presumably too old to learn additional languages effectively, but target language (TL) input appears to be insufficient, especially when other languages are allowed in class. Nevertheless,…

This study examines the role of language proficiency and other individual factors (attitudes, input) in the acquisition of language-specific [ð] and dialect-specific [Ø] allophones of Spanish intervocalic /d/ in the /ado/ context by L2 and heritage Spanish speakers during a short-term study abroad in Sevilla, Spain. Twenty L2-intermediate, 10…

The interactionist hypothesis holds that conversational interaction facilitates second language (L2) learning by providing learners opportunities to receive meaningful input, modify their output, and attend to language form. Although research has often explored the efficacy of different types of L2 instruction (deductive or inductive), few studies…

The current study contributes to the argument regarding whether L2 learners up to advanced levels make agreement errors on grammatical gender. It reports gender agreement accuracy on a written Grammaticality Judgment Task (GJT) and an Elicited Oral Production Task (PDT) on known nouns assigned the correct gender by participants on a vocabulary…

Within the field of linguistics, whether considering language contact situations (Weinreich, 1979) or foreign language education (Lado, 1957), the topic of language transfer, especially as it relates to pronunciation, has always been an item of particular interest. While research on such transfer has mostly focused on various phenomena of the L1…

We investigated whether bilinguals' integration of a code-switch during real-time comprehension, which involves resolving among conflicting linguistic representations, modulates the deployment of cognitive-control mechanisms. In the current experiment, Spanish-English bilinguals (N = 48) completed a cross-task conflict-adaptation paradigm that…

Second language acquisition has been observed to be variable in its outcome such that, unlike native speakers, all second language learners do not achieve total success. Second language acquisition is made of macro and micro processes. External and internal (e.g., age, individual differences) factors are assumed to affect language processing in…

The onset of COVID-19 has prompted world language professionals to reconceptualize best practices in second language (L2) teaching and research during a time of limited interaction due to social distancing across the globe (Morris, 2022). Not surprisingly, study abroad programs that once fostered communicative and intercultural development were…

The current study examined the effect of speaker variability on children's cross-situational word learning (XSWL). The study also examined the role of bilingual experience and sustained attention. Forty English monolingual children and 40 Spanish-English bilingual children ages 4-7 completed a XSWL task in a Single Speaker Condition and a Multiple…

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…

This study builds on prior research on second language (L2) Spanish psych verbs, which has centered on morphosyntactic properties, by examining their syntactic distribution, which relies on lexical semantic knowledge. The fact that certain forms are licensed for some verbs, but not others, is the result of an underlying lexical semantic difference…

The Spanish subjunctive mood (SUBJ) is said to be highly vulnerable in heritage language (HL) acquisition. However, there is little controlled research on HL-speaking children acquiring the various Spanish SUBJ contexts, so we do not have a clear picture of when, how, or why heritage speakers (HSs) develop in the SUBJ as they do. This study tests…

This study was designed to explore improvement in conversational interactions by English speakers learning Spanish when exposed to task-based speaking activities in three phases. Fifty-three college students enrolled in Intermediate Spanish 1 and Intermediate Spanish 2 engaged in input activities, recorded summaries and reflections on the input…

Preposition knowledge is important for academic success. The goal of this project was to examine how different variables such as English input and output, Spanish preposition score, mother education level, and age of English exposure (AoEE) may have played a role in children's preposition knowledge in English. 148 Spanish-English children between…
