Previous research indicates that developmental contexts influence language development. These developmental contexts include bilingualism, which is the focus of the current paper. This study analyses the influence that the acquisition of a language, Catalan, has when the simultaneous acquisition of another similar language, Spanish, occurs. This…

Literature on early language acquisition has observed that age of onset of acquisition (AoA) is relevant for certain grammatical phenomena. Simultaneous bilinguals receive regular and extensive exposure to two languages from birth (Müller, 2009), whereas sequential child learners get in extensive contact to L[subscript B] once the L[subscript A]…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results. This study investigated the effects of exposure and age of onset of acquisition (AOA) of L3-English, as well as first and second language (L1/L2) skills and use, in the development of…

This study investigates the knowledge of bilingual speakers of Catalan and Spanish regarding the production of object pronominal clitics (excluding non-reflexive third-person clitics), with a focus on: (i) their morphology, considering the variants that coexist for each form, and (ii) their syntactic placement (proclitic or enclitic) with respect…

This study explores the effects of extensive audio-visual input with three captioning modes -- unenhanced captions, textually enhanced captions, and no captions -- on learning a variety of L2 grammatical constructions and examines the effects of three learnability factors: construction type, frequency, and recency. A total of 112 participants…

This study compares the language proficiency gains of two groups of students taking a business English course module in a bilingual university in Catalonia (Spain). Whereas one of these groups followed a 'translanguaging' or 'plurilingual' pedagogy, the other followed a strictly monolingual approach. Participants were 54 mostly Catalan/Spanish…

This article addresses the benefits of audio-visual input for learning second language (L2) vocabulary and grammatical constructions. Specifically, it explores the role of frequency, the effects of subtitles and captions, and the mediating role of learner proficiency on language gains in two longitudinal studies. Study 1 targets vocabulary…

Bilingualism is associated with lifelong cognitive benefits that correlate with facilitated achievements in subsequent language learning. Second language (L2) instruction as well can promote the development of cognitive abilities involved in language learning, and among these, L2 input processing. Crucial to L2 acquisition, input processing is the…

Background: Children with a diagnosis of specific language impairment (SLI) present impaired oral comprehension. According to the simple view of reading, general amodal linguistic capacity accounts for both oral and reading comprehension. Considering this, we should expect SLI children to display a reading comprehension deficit. However, previous…

The development of spelling skill is an intricate process for children with or at risk of Specific Learning Disabilities and requires targeted interventions. This problem exacerbates in the Greek orthographic system owning to its high complexity. The current study presents a novel spelling intervention program for Greek 3rd graders at risk of…

Why is it more difficult to comprehend a 2nd (L2) than a 1st language (L1)? In the present article we investigate whether difficulties during L2 sentence comprehension come from differences in the way L1 and L2 speakers anticipate upcoming words. We recorded the brain activity (event-related potentials) of Spanish monolinguals, French-Spanish late…

A robust finding from studies investigating the Aspect Hypothesis is that learners at the early stages of acquisition show a strong preference for using the progressive aspect as associated with activity verbs. As they advance in their acquisition of the second or foreign language, learners move from this prototypical association to associations…

Compares the results from monolingual children with object omissions in bilingual children who have acquired two languages simultaneously. Claims that the difference between monolingual and bilingual children is due to crosslinguistic influences in bilingual children. (Author/VWL)

Responds to comments by various researchers on an early article presented in the same issue of this journal, claiming that language separation and crosslinguistic influence coexist in bilingual first language acquisition. (Author/VWL)
