The Topic Hypothesis posits that Chinese language learners progress through a developmental sequence comprising five stages (Gao, 2009; Wang, 2011), which includes the Object-Subject-Verb (OSV) structure at stage 4 and the ba-construct at stage 5. According to this hypothesis, learners typically master the OSV structure before acquiring the…

This study investigated the interactions among different cognitive abilities, linguistic structures, and the efficacy of different corrective feedback (CF) types. The cognitive abilities examined were declarative and procedural memory. The target linguistic structures were English regular and irregular past tense forms. In terms of the…

Purpose: This study examined two markers of language impairment (LI) in a single experiment, testing sentence imitation and grammatical morphology production using an imitation task with masked morphemes. One goal was to test predictions of the morphological richness account of LI in Czech. We also tested the independent contributions of language…

Task-Based Language Teaching has been developed in response to the teacher-dominated, focus-on-forms methods such as Present, Practice, Produce (PPP). The body of literature is replete with studies examining the learning efficacy of the PPP approach versus TBLT; however, these studies did not use assessment tasks in comparing these two methods. To…

As second language (L2) research adapts to the dynamics of multimodal instruction, researchers are exploring the role of captioning and textual enhancement (TE) on learner development. The present experiment assesses the differential effects of textually enhanced captions on learners' elicited imitation of L2 Spanish grammar. Twenty-eight…

This exploratory study evaluated the impact of a Spanish second language (L2) domestic immersion (DI) program that was developed expediently at a large university in the United States in response to widespread study abroad (SA) program closures due to COVID-19. Spanish language learners (n = 14) participated in an intensive, six-week summer…

Individual differences (IDs) largely contribute to success in adult second language attainment (e.g., Dörnyei, 2006). Heritage language (HL) studies have also explored the role of IDs, namely psychosocial variables, and biographical factors with an adult HL learner population. However, the specific contribution of these variables to HL learners'…

This study investigated the effects of task complexity on child learners' second language (L2) gains, the relationship between aptitude and L2 development, and the extent to which task complexity influences this relationship when recasts are provided. Sixty child EFL learners were assigned to two experimental groups. During the treatment, one…

This article aims to investigate how Dutch children may eventually converge on a targetlike distribution of "hoeven" 'need,' a modal verbal NPI (Negative Polarity Item), based on its appearance in the scope of merely some but not all of its possible licensers in the language input (i.e., the induction problem). Imitation performance was…

This article presents a generative analysis of the acquisition of formulaic language as an alternative to current usage-based proposals. One influential view of the role of formulaic expressions in second language (L2) development is that they are a bootstrapping mechanism into the L2 grammar; an initial repertoire of constructions allows for…

The article reports on a study investigating the comparative effects of immediate and delayed corrective feedback in learning the English past passive construction, a linguistic structure of which the learners had little prior knowledge. A total of 120 learners of English as a foreign language (EFL) from 4 intact classes at a Chinese middle school…

This study builds on research investigating the construct validity of elicited imitation (EI) as a measure of implicit second language (L2) grammatical knowledge. It differs from previous studies in that the EI task focuses on a single grammatical feature and time on task is strictly controlled. Seventy-three EFL learners and 20 native English…

This dissertation examines Spanish Direct Object clitic pronouns in Argentine spoken Spanish of adults and children (ages 4;0-7;0). It concentrates on (Finite verb + Nonfinite verb) constructions that allow both pre-verbal (Proclisis) and a postverbal (Enclisis) clitic placement. Previous corpus studies have shown that lexical (finite verb),…

This study investigates the role of previously acquired linguistic systems, Mazandarani and Persian, in the acquisition of third language (L3) English at the initial stages. The data have been obtained from 31 students (age 13-14 years), testing the placement of attributive possessives in a grammaticality judgment task, an element rearrangement…

This study examined the second language (L2) development of adult learners of Spanish at three levels of proficiency during and after a semester of instruction. A fundamental goal was to identify cognitive and psychosocial individual differences (IDs) that can explain between-learner variation over time in order to expand our understanding of the…
