Evidence from usage-based studies of second language (L2) acquisition reveals that a main source of L2 learners' developing grammars is the L2 input to which learners are regularly exposed. What learners develop from their extended engagement in the sequences of actions comprising the input is not an acontextual system of grammatical units but…

It remains an open question whether second language (L2) learners can process linguistic properties at the syntax-discourse interface. This study examines this issue in the context of the L2 processing of Korean dative sentences under different information structure requirements. Given that discourse constraints associated with information…

This study investigates the extent to which paper-based data-driven learning (DDL) activities can improve Thai EFL students' grammar learning of conditional sentences (the second condition), as well as the participants' attitudes toward learning through the DDL approach. This was a two-week research using a one-group pre-test and post-test design.…

The current study examined Thai EFL Mattayom learners' pragmatic discourse of givenness via A-movement constructions. While previous studies focused on Thai undergraduate students and their error production in passive voice, this study innovatively contributes to the field by selecting a different group of participants. The participants in this…

This study examined number marking comprehension among Japanese learners of second language (L2) English, whose first language (L1) does not have an obligatory number marking system. The study conducted an online sentence comprehension experiment with 96 L1-Japanese learners and 32 native speakers of English, wherein participants engaged in a…

This study sought to investigate the key determining characteristics in the writing performance of first-year Chulalongkorn University students across language proficiency levels as measured by CU-TEP. The focus was on both syntactic and lexical complexity components. The sample comprised the writings from a corpus of 4,812 first-year students…

Languages differ regarding the depth, structure, and syntactic domains of recursive structures. Even within a single language, some structures allow infinite self-embedding while others are more restricted. For example, when expressing ownership relation, English allows infinite embedding of the prenominal genitive "-s," whereas the…

We discuss the causative-inchoative alternation in Turkish Sign Language (Türk Isaret Dili -- TID), and the age of acquisition effects on multi-predicate, complex constructions that are observed in both causative and inchoative events. We present a picture-description task performed by 24 adult signers, half of which were exposed to TID from birth…

Graded reading is one of the important ways of English learning. How to automatically judge and grade the difficulty of the English reading corpus is of great significance for precision teaching and personalized learning. However, the current rule-based readability assessment methods have some limitations, such as low efficiency and poor accuracy.…

The present dissertation reports two experiments that examine implicit and explicit language learning methods and their impacts on early vocabulary, grammar, and phonological acquisition, in addition to working memory, proactive/reactive control, and fluid intelligence, as well as learner motivation. Experiment 1 investigated adult L2 acquisition…

Natural languages contain systematic relationships between verb meaning and verb argument structure. Artificial language learning studies typically remove those relationships and instead pair verb meanings randomly with structures. Adult participants in such studies can detect statistical regularities associated with words in these languages and…

This study explored the influence of speech rate (normal vs. fast), sentence length (short vs. long), and second language (L2) oral proficiency on listening comprehension in L2 Spanish. Thirty-one native English-speaking learners enrolled in upper-level Spanish courses were aurally exposed to 8 sentences of each type of speed--length matrix, for a…

Languages vary with respect to whether sentences with two negative elements give rise to double negation or negative concord meanings. We explore an influential hypothesis about what governs this variation: namely, that whether a language exhibits double negation or negative concord is partly determined by the phonological and syntactic nature of…

EFL students' attitudes are crucial for the development of writing abilities, which in the age of cutting-edge technology depend extensively on artificial intelligence-mediated tools, and paraphrasing draws no exception. Therefore, this study aims to identify English as a foreign language student's enthusiasm and insights about utilizing QuillBot…

This study examines the knowledge representation of Japanese university students assessed using grammaticality judgement tests (GJTs) and a metalinguistic knowledge test (MKT). The study also investigates the role of automatised and non-automatised explicit knowledge in general L2 language proficiency. Participants were 87 late learners of English…
