This study aims to investigate ChatGPT's ability to comprehend input from nonnative speakers, specifically those learning English as a second language, with Japanese speakers serving as the model population. The experiment examines how ChatGPT evaluates the difficulty levels of the Test of English for International Communication (TOEIC), which is…

German plural formation appears unsystematic and largely arbitrary to many second language (L2) learners. While some approaches have attempted to identify patterns and rules to help L2 learners (e.g., Anton et al., 2017; Di Donato & Clyde, 2020; Kraiss, 2014), one central observation from linguistic analysis has been absent from pedagogical…

Spanish heritage speakers in the United States exhibit a wide range of linguistic profiles due to a combination of political, social, and educational factors. Most of them acquire Spanish at home without formal instruction in writing. Although previous research has explored the main challenges faced by these learners in Spanish writing courses, no…

This study examined how students of English as a foreign language (EFL) with different first language (L1) backgrounds use interactional metadiscourse markers in argumentative writing. Specifically, to explore unique patterns of metadiscourse features that reflect context and development, the essays written by Chinese, Japanese, and Korean EFL…

Second language (L2) acquisition research has explored the acquisition of various syntactic constraints by L2 learners, one of which is "wanna" contraction. However, there is still a very limited body of research regarding the acquisition of "wanna" contraction, both in first language (L1) and L2. The purpose of the study is to…

For monolingual English-speaking children, judgment and production of stress in derived words, including words with phonologically neutral (e.g., -ness) and non-neutral suffixes (e.g., "-ity"), is important to both academic vocabulary growth and to word reading. For Mandarin-speaking adult English learners (AELs) the challenge of…

The speech of second language learners is often influenced by phonetic patterns of their first language. This can make them difficult to understand, but sometimes for listeners of the same first language to a lesser extent than for native listeners. The present study investigates listeners' awareness of the accent by asking whether accented speech…

The current project investigates developmental aspects of acquiring locative verb constructions in English as a second language. Locative verbs, such as "to pour," "to spill," "to spray," and "to sprinkle," constitute a prototypical case of an overgeneralization problem in language learning: Whereas some of…

Constructionist research on L2 learning has focused on the degrees to which skewed frequency (Goldberg, Casenhiser & White, 2007; Casenhiser & Goldberg, 2005; Goldberg, Casenhiser, & Sethuraman 2004) in a person's linguistic environment can facilitate "entrenchment," "schematization," and "contingency…

The purpose of this study is to investigate the influence of first language thinking-for-speaking patterns on the acquisition of Greek as a second language (L2), as well as to determine whether proficiency level and stays in the target-language country have an effect on such influence. The participants (N = 50) were Spanish/Catalan learners of…

This dissertation provides a comprehensive analysis of the L2 acquisition of Spanish psych-verbs (e.g. "gustar" "to like") across four different proficiency levels. In particular, psych-verbs constitute a testing ground for the predictions of the Interface Hypothesis (Sorace and Filiaci, 2006; Tsimpli, Sorace, Heycok &…

Limited research has investigated advanced language learners' acquisition of English verbs. The current study examines and compares the acquisition pattern of English verbs among Chinese second language (L2) learners at both intermediate and advanced levels to answer the following questions: (1) Do L2 learners acquire regular verbs and irregular…

Typological differences in expressions of motion are argued to have consequences for event conceptualization. In SLA, studies generally find transfer of L1 expressions and accompanying event construals, suggesting resistance to the restructuring of event conceptualization. The current study tackles such restructuring in SLA within the context of…

The literature on formulaic language lacks sufficient research on how L2 learners make progress in native-like formulaicity of their target language. This study analyzed the use of formulaic sequences (FSs) by 56 Chinese university English majors in their prepared monologues at the beginning and end of a three-year period and compared the student…

With Chinese native-speaker data as the baseline, this study investigates the use of the morphosyntactic particle DE by learners of Chinese as a second language. The general patterns are as follows: (a) DE tends to be deleted more in informal speech than in formal settings; (b) higher proficiency and longer residence in China--more interactions…
