This study investigated how input frequency (i.e., type frequency and token frequency) and proficiency levels enhanced the perception of English nominal suffixes by first language (L1) Thai learners. Based on the Usage-based Account (Tomasello, 2003), it was hypothesized that input frequency, i.e., token frequency (frequency of derived forms…

Second language acquisition (SLA) research offers valuable insight on how languages are learned and how they coexist and influence each other. Sign language learners offer unique perspectives on SLA, allowing researchers to test theories that are otherwise constrained by access to only one modality. Current literature on sign language learning…

This study examined the production of L3 French words by Spanish--English bilinguals who had no prior knowledge of the L3. Using a shadowing task, 39 Spanish L1/English L2 and 18 Spanish monolingual speakers produced 26 tokens of word-initial voiceless plosive consonants in French, Spanish and English (15 Spanish and French tokens for the…

Since corpus linguistics gained popularity as a methodology in the latter half of the 20th century, second language acquisition research has seen the emergence of work investigating formulaic language, such as idioms, lexical bundles, and collocations. A collocation is a string of words that co-occur more routinely than probability would predict,…

The linguistic relativity hypothesis has focused on the influence of grammar in language on speakers' cognition. Previous studies show that speakers of languages with grammatical number (e.g., English) are more aware of the number of objects. Additionally, recent studies reveal that bilinguals who speak languages with different grammatical…

The acquisition of a second language (L2) may be challenging in adulthood, as the phonological system of the native language (L1) can sometimes limit the perception of phonological contrasts in L2. The present study aimed to (a) examine the influence of an L1 (Hebrew) that lacks a phonemic contrast for vowel length on the ability to discriminate…

This study aimed to examine the effects of an AI-based object detection translation (AI-based ODT) application (app) on EFL students' vocabulary learning. We developed a system that utilized strategies to facilitate learners' vocabulary learning. The app applied dual code theory to present the objects in picture, word, and pronunciation formats.…

This paper explores the hypothesis that children pay more attention to phonological cues than semantic cues when acquiring grammatical patterns. In a series of artificial allomorphy learning experiments with adults and children we find support for this hypothesis but only for those learners who do not show clear signs of explicit learning. In…

This study investigates whether there are different first-language-second-language (L1-L2) dependency resolutions by focusing on less-studied crosslinguistic variances in L2 acquisition of Chinese, a null-subject language, by speakers of English, a non-null-subject language. The overt subject pronoun of a Chinese main clause has free orientation…

This dissertation investigates how bilinguals use their two grammars to comprehend written intra-sentential codeswitches. I focus on adjective/noun constructions in Spanish and English where I manipulate the congruence of grammatical word order in the two languages across the codeswitch boundary. This allows me to test three codeswitching…

This article reports on an experimental study on the acquisition of prepositional relative clauses in second language European Portuguese by Chinese native speakers. It focuses on the role of resumption, mandatory in prepositional relative clauses in Chinese (the native language of the learners) and non-conventional in European Portuguese (the…

Many studies evidence the flexibility of speech perception in the first language (L1), which allows rapid adaptation to unfamiliar foreign accents. Two influential studies by Bradlow and Bent (2008) and a follow-up study by Baese-Berk et al. (2013) found that increased variability as a function of the number of talkers and accents facilitated the…

The present study examines the production and intuition of Spanish clitics in clitic left dislocation (CLLD) structures among 26 Spanish heritage speakers (HSs) born and raised in Brazil. We tested clitic production and intuition in contexts in which Spanish clitics vary as a function of the semantic features of the object that they refer to.…

Current models of the affinity between syntax and vocabulary are complex and recognize the contribution of bootstrapping and computational processes. To date, the mutual facilitation between these two constructs over time has not been studied in second language (L2) school children. The present study investigated longitudinally the direction and…

Research on second-language (L2) acquisition has identified linguistic domains that appear to be especially difficult to learn--one such sticking point being syntactic structures that depend on the surrounding discourse. The Interface Hypothesis (IH) explains what makes such constructions problematic by appealing to a modular view of language,…
