This study investigated three key issues in heritage language (HL) research. Previous research shows HL speakers have an advantage on oral production tasks compared to L2 speakers who instead perform better on written tasks. Furthermore, both L2 and HL speakers are claimed to have a "yes-bias" towards retaining ungrammaticality in GJTs.…

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…

Purpose: The current study examined language control and code-switching in bilingual children with developmental language disorder (DLD) compared to bilingual peers with typical language development (TLD). In addition, proficiency in each language and cognitive control skills were examined as predictors of children's tendency to engage in…

The Matthew effects suggest that children who struggle when learning to read are less likely to read for pleasure later in life compared to children who ease into reading quickly. One aspect of early literacy instruction that might hamper reading progress is learning to read simultaneously in two languages. Despite the long-lasting and widespread…

Heritage language (HL) speakers seem to diverge from monolingual speakers in the acquisition of syntax-discourse interface phenomena. However, most of the studies reporting this finding do not make any distinction between different types of syntax-discourse interface structures. Therefore, it is an open question whether these structures are…

Purpose: This article aims to describe how exemplar variability can manipulate the word learning environment to maximize within- and cross-language generalization in Spanish--English bilinguals. Furthermore, we examined sources of individual variability that predicted word learning. Method: Nineteen Spanish--English bilingual children participated…

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…

The present study examines and compares the extent to which advanced L2 learners of Spanish and Spanish heritage speakers acquire the syntactic and semantic properties that regulate the grammatical representation of double complementizer questions in Spanish, a CP-related structure not present in English. Results from an aural sentence completion…

This study aims to examine language dominance and language switching effects in a series of monolingual and multilingual lexical decisions in which participants have to decide if the presented letter string is a word or not, regardless of language. Thirty participants (12 French-English bilinguals and 18 French-English-Spanish trilinguals) were…

This study investigates the effects of weekly heritage language (HL) classes on first language (L1) proficiency in speakers who arrived in the second language (L2)-dominant setting before the onset of puberty. Two groups of L1 Spanish--L2 Swedish bilingual high school students living in Sweden participated in the study. One group currently…

This study explores the extent to which a bilingual advantage can be observed for executive function tasks in children of varying levels of language dominance, and examines the contributions of general cognitive knowledge, linguistic abilities, language use and socio-economic level to performance. Welsh-English bilingual and English monolingual…
