Acquisition of an argument structure may be affected by the diversity of lexical types that appear in that structure (Conwell et al., 2011; Yang, 2016). Seventy-two 5- and 6-year-old English-speaking children completed a learning study where they were exposed to a novel argument structure and then tested on their ability to comprehend it. The…

This study builds upon previous research investigating the construct validity of phraseological complexity as an index of L2 development and proficiency. Whereas previous studies have focused on cross-sectional comparisons of written productions across proficiency levels, the current study compares the "longitudinal" development of…

Growing up in the digital era, young children are exposed to numerous educational applications and programs, some with well-designed curricula and others focused more on entertainment or game-like qualities. With the increasing popularity of mobile language-learning applications among young children, this dissertation raises a crucial question: do…

Event concepts of common verbs (e.g. "eat," "sleep") can be broadly shared across languages, but a given language's rules for subcategorization are largely arbitrary and vary substantially across languages. When subcategorization information does not match between first language (L1) and second language (L2), how does this…

Dative alternation between prepositional and double object datives has been a popular topic in second language (L2) acquisition, but only few studies deal with discourse constraints such as the "given-before-new" principle, or given-new (GN) ordering, which describes the tendency to place given information before new information. The…

The current study explores the effects of processing demands and proficiency on second language (L2) learners' acceptability judgment of wh-island sentences. A total of 65 adult Korean learners of English and ten native speakers (NSs) of English participated in an experiment that combined self-paced reading and acceptability judgment. They were…

This study investigated the acquisition of English "control" and "raising" ("over Experiencer") constructions with three groups of Thai EFL learners (lower intermediate, intermediate, and advanced). Thai and English, with respect to "control," commonly have PRO and infinitive markers, but Thai does not…

Although numerous studies show that intelligence, measured by various tests, is a significant predictor of school achievement, this cognitive variable can only explain about 50% of the variance. It is also known that communicative language ability represents an important basis for learning subject content in the early period of formal education.…

Previous studies using artificial languages suggest that sentence production can be guided by verb-specific as well as verb-general statistics present in the language input. Here we investigated whether the statistical properties of ongoing input in the speakers' native language systematically affected their sentence production. Three experiments…

The present study investigates whether or not Thai students' English writing skills can be improved by using an online grammar checker. First, typical syntactic errors made by undergraduate students majoring in English and English for Careers were examined. Secondly, possible reasons for syntactic errors in English writing in the light of Lado's…

The present investigation examines intra-speaker variability in heritage speakers (HSs) of Spanish by focusing on the potential effects of two variables in their acquisition of mood: lexical frequency and morphological regularity. To do so, this study tested participants' interpretation and use of early-acquired mood alternations conveying either…

This study investigated Thai EFL learners' acquisition of English dative constructions, i.e., Prepositional Dative (PD) and Double Object (DO) constructions employing Radford's (2004) Minimalist accounts as a framework and Acceptability Judgment as a task. Two hypotheses were formulated. Firstly, the English PD would be accepted more readily than…

To investigate L2 adolescent learners' use of machine translation (MT), an MT error correction (EC) test was developed, based on the analysis of MT errors arising from translating the learners' L1 of middle school EFL textbooks. Learners were also asked to report on their use of MT EC strategies on the EC task. Results indicated that…

This study investigates the use of high-frequency cognitive verbs - think and believe - in Turkish L2 learners' interlanguage, both in terms of their verb senses and complementation patterns. In line with this purpose, a Sentence Production Task consisting of context-independent items and a Sentence Completion Task consisting of context-dependent…

This study tests the Competing Systems Hypothesis (CSH) as applied to adult second language acquisition of aspect in Spanish. The CSH purports that differences among tutored and untutored learners result from competition between one system of underlying grammatical knowledge and another of learned metalinguistic knowledge in tutored learners…
