This study investigates the hypothesis that non-isomorphic syntax-semantics mappings pose a greater challenge for non-native (L2) than for native (L1) speakers, focusing on a previously understudied phenomenon. We carried out an antecedent judgment task with L1 German and L1 Russian-speaking, proficient L2 learners of German to examine Condition C…

This study investigated English phonological awareness in adult native speakers of English (L1) and in relation to their phonological awareness skills and proficiency in their German (L2). Most research in L1 phonological awareness focuses on younger children, their phonological awareness development, the relationship between reading and…

While it is known that heritage speakers diverge from the homeland baseline, there is still no consensus on the mechanisms triggering this divergence. We investigate the impact of two potential factors shaping adult heritage language (HL) grammars: (1) cross-linguistic influence (CLI), originally proposed for second language acquisition (SLA), and…

This article reports on two experiments that examine the computation of contrastive focus in Russian on the part of adult English-dominant heritage speakers and second language learners of Russian, in comparison with baseline monolinguals. The first experiment uses an acceptability judgment task to determine whether bilingual and monolingual…

This study explored appropriate speaking activities for speakers of different proficiency levels by measuring the changes in their brain blood flow with near-infrared spectroscopy (NIRS). Fifty adult speakers and learners of English of various proficiency levels participated in the study by undertaking four types of task: a single-speaker picture…

This article explores how multiple linguistic cues interact in predictive processing among second language (L2) learners. In a visual-world eye-tracking experiment, we investigated whether learners of German use case and prosody cues together to assign thematic roles and predict post-verbal arguments. During the experiment, participants listened…

Previous studies have yielded contradictory results on the relationship between perception and production in second language (L2) phonological processing. We re-examine the relationship between the two modalities both within and across processing levels, addressing several issues regarding methodology and statistical analyses. We focus on the…

Previous and current research identify Metalinguistic Awareness (MLA) as a possible cause of the positive effects of bilingualism on cognitive development and Third Language Acquisition (TLA). Although it has been acknowledged that MLA is strongly affected by literacy and grammar-related activities, only a few studies have focused on the context…

The present dissertation analyzed speech production and perception in early heritage Spanish-English bilingual children. Specifically, I investigated how perception and production of lexical stress develops in bilingual children. Current models of second language (L2) speech perception do not include heritage bilinguals or suprasegmental aspects…

This article investigates whether explicit instruction can affect second language (L2) competence in the domain of English quantifier scope. An intervention study was conducted with L1-Mandarin L2-English learners in order to examine (1) whether these learners can learn inverse scope for the structure on which they are instructed…

The benefits of task-based interaction in Second Language Learning (SLL) have been made increasingly evident in the literature. However, unlike adult studies, only recently has interaction research on EFL children grown in popularity. Most children-based research has focused primarily on Negotiation of Meaning, while other age-related aspects,…

The use of English-origin spontaneous loanwords (e.g., "la babysitter," "el counter," etc.) in otherwise Spanish discourse is criticized by many as a strategy that bilinguals use to compensate for a lack of lexical knowledge in Spanish. The purpose of the current research is to examine the question of lexical proficiency as a…

This study examined Spanish-Welsh (in Patagonia) and Welsh-English (in North Wales) bilingual children's and adults' processing of sentences in which two noun phrases acted as arguments of a verb. The goal was to determine the relative importance of distinct cues to the identification of the subject in the bilinguals' processing of their two…

According to the Interface Hypothesis (IH) (e.g., Tsimpli & Sorace 2006; Sorace 2011), external interfaces are more challenging for L2 learners than internal interfaces. It is not clear, however, if linguistic phenomena associated with external interfaces are necessarily problematic and if internal interfaces are necessarily unproblematic. In…

Native-English speaking adults use morphological decomposition to understand complex words (e.g. "farmer" becomes "farm-er"). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking…
