The goal of this paper is to tease apart two approaches to the source of children's consistent scope assignment in negative sentences containing logical connectives: the Semantic Subset Principle and the Semantic Subset Maxim. Previous developmental work has observed that four- to six-year-old children across languages have difficulty with…

In a body of empirical research, it has been observed that young children from across different linguistic communities adhered to a particular type of nonadult interpretation of disjunction: They appear to interpret disjunction conjunctively. Through three experiments with Japanese-speaking preschoolers, we investigate the source of this nonadult…

Research has shown that learning a known-and-unknown word combination leads to greater learning than learning an unknown word alone (Kasahara, 2010, 2011). These studies found that attaching a known adjective to an unknown noun can help learners remember the unknown noun. Kasahara (2015) found that a known verb can serve as an effective cue to…

Connectives such as "because" and "but" are crucial for signaling coherence relations in discourse. They contribute to a better reading comprehension and, thus, academic performance. The aim of this article is to contribute to our understanding of connective development during teenage years by studying individual differences in…

L3 acquisition is influenced by L1-L3 typology, learners' proficiency in those languages, and metalinguistic knowledge. However, the precise patterns of cross-linguistic influence (CLI) in L3 acquisition are still unclear. This study aimed to examine how the abovementioned factors affect learners' sensitivity to subject placement in L3 Italian. We…

While previous research has provided insights into vocabulary learning through extensive reading, the differential effects of word frequency and word class on active form and passive meaning word recognition remain less understood. By evaluating learners' post-test performance in active form recognition and passive meaning recognition, this study…

This study investigates (1) whether second language learners (L2ers) acquire the Mandarin system of pronouns and reflexives despite differences from their first languages (L1s) and (2) whether L1-English and L1-Korean L2ers differ due to L1-transfer. Unlike English, Mandarin and Korean allow long-distance (LD) reflexives. While…

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…

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…

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…

This study explored second language (L2) competence in discontinuous discursive formulaic sequences, namely Chinese correlative connectives (CCCs; e.g. yinwei . . . suy 'because . . . so'), in relation to the determinants of formulaic sequence acquisition by scrutinizing L2 Chinese learners' performance on two controlled tasks. Mixed-effects…

This study attempts to explain a systematic phenomenon that has been described in interlanguage grammars crosslinguistically: Null-Prep, which consists of omitting the obligatory preposition in certain movement constructions. We propose that Null-Prep is not related to lack of knowledge of "wh"-movement, as previously assumed, but to…

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…

During narration, speakers constantly choose appropriate referential forms (nominals or pronominals). Children may engage in this reference marking differently than adults. Discourse- or listener-oriented approaches make different predictions about referential behaviour in cognitively demanding situations: the first predicts a higher number of…

This study investigates the effects of input-based and output-based instructions on the acquisition of second language (L2) request modifiers. Four intact classes were randomly assigned to textual enhancement (TE), input flooding (IF), output-based instruction (OI), and control (CO) groups. The TE group watched some captioned videos on requests…
