Usage-based theory has proposed that learning of linguistic constructions is facilitated by input that contains few high-frequency exemplars, in what is known as a skewed (or Zipfian) input distribution. Early empirical work provided support to this idea, but subsequent L2 research has provided mixed findings. However, previous approaches have not…

The purpose of this comparative study is to determine whether the linguistic input approach based on Krashen's (1989) comprehensible input (CI) and supported by Kolb's (2015) experiential learning (ELT) and Siemens' (2005) connectivism theory (CT) to improve eighth graders' Spanish speaking and writing linguistic proficiencies. Previous research…

This article provides a Poverty of Stimulus argument for the participation of a dedicated linguistic module in second language acquisition. We study the second language (L2) acquisition of a subset of English infinitive complements that exhibit the following properties: (a) they present an intricate web of grammatical constraints while (b) they…

Children with developmental language disorder (DLD) have significant deficits in language ability that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. The symptoms displayed by children with DLD differ across languages. In English, DLD is often marked by severe difficulties acquiring verb inflection.…

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…

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 ability to communicate in different languages is increasingly essential in today's interconnected world. However, language learning outcomes can often suffer due to low engagement and participation, especially among students from diverse cultural and socioeconomic backgrounds. To address this challenge, it is crucial to create a culturally…

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 present article sought to compare two case studies on the relationship between the theories of Language Acquisition and of their application for EFL Teachers Programs, in two different national settings. The first one conducted in the Republic of Chile and the second one, more recently developed in the Dominican Republic. It prompted our…

Cross-linguistically, monolingual children produce target-like inflected verbs much earlier than they can reliably distinguish between singular and plural subject-verb agreement morphology in comprehension (i.e. Johnson, V., J. de Villiers, and H. Seymour. 2005. "Agreement Without Understanding? The Case of Third Person Singular /s/."…

Educational media is ubiquitous in the lives of young children, promising high-quality programming to equip them with vocabulary knowledge and school readiness. To meet the needs of preschool-aged dual-language learners (DLLs), many educational programs are marketed to promote vocabulary learning in two languages. In this study, we use a content…

In seeking to both confirm previous conclusions and expand the literature of the field with a different group of participants, McNulty (2012) was (partially) replicated. Three instructional interventions were designed to ascertain which activity type was responsible for learner gains. One treatment group (R) included referential-only practice…

In this commentary, the author defends the Multiple Grammars (MG) theory proposed by Luiz Amaral and Tom Roepe (A&R) in the present issue. Topics discussed include second language acquisition, the concept of developmental optionality, and the idea that structural decisions involve the lexical dimension. The author states that A&R's…

This study examined how emergent bilingual children's English and Spanish proficiencies moderated the relationships between Spanish and English input at home (bilingual home language input [BHLI]) and children's oral language skills in each language. The sample comprised over 1,400 Spanish-dominant kindergartners in California and Texas. BHLI was…
