Acquisition of the perfective marker "-le" in Mandarin Chinese is a daunting task for second language learners. To date, there has been no consensus on what it is about "-le" that makes it such a challenge to learners. This study investigates the acquisition of "-le" from both a lexical perspective and a discourse…

Usage-based theory has proposed that learning of linguistic constructions is facilitated by input that contains few high-frequency exemplars, in what is known as a skewed (or Zipfian) input distribution. Early empirical work provided support to this idea, but subsequent L2 research has provided mixed findings. However, previous approaches have not…

One of the fundamental questions in the field of language acquisition is a learnability problem, which considers how learners acquire certain aspects of language which are not directly provided in the input or whose referents are not readily observable. This dissertation investigates Japanese children's acquisition of various linguistic phenomena,…

This dissertation investigates when and how children figure out the force of modals, that is, when and how they learn that "can/might" express possibility, whereas must/have to express necessity. Learning modal force raises a logical "Subset Problem": given that necessity entails possibility, what prevents learners from…

We investigated whether children's inhibitory control (IC) is associated with their ability to produce irregular past tense verb forms as well as learn from corrective feedback following overregularization errors. Forty-eight 3;6 to 4;5 year old children were tested on the irregular past tense and provided with adult corrective input via models of…

Literature on early language acquisition has observed that age of onset of acquisition (AoA) is relevant for certain grammatical phenomena. Simultaneous bilinguals receive regular and extensive exposure to two languages from birth (Müller, 2009), whereas sequential child learners get in extensive contact to L[subscript B] once the L[subscript A]…

The relationship between language and thought has fascinated us for centuries. The relationship between the two is far beyond what the two words represent on the literal level, and the discussions around it have been covered in various fields from philosophy and psychology to linguistics. Even complicating the situation, the relationship between…

Many studies investigated metaphors in news; however, few of them focused specifically on headlines. By investigating metaphors in 133 collected NBA news headlines written in Chinese, this paper analyzes the creativity in them. Conceptual Metaphor Theory, including conceptual metonymy, is adopted to discuss creative linguistic metaphors and their…

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.…

This paper revisits the longstanding observation that children produce modal verbs (e.g., must, could) with their root meanings (e.g., abilities, obligations) by age 2, typically a year or more earlier than with their epistemic meanings (e.g., inferences). Established explanations for this "Epistemic Gap" argue that epistemic language…

The "wanna" facts are a classic Poverty of Stimulus (PoS) problem: "Wanna" is grammatical in certain contexts ("Who do you want PRO to play with?") but not others ("Who do you want who[strikethrough] to play with you?"). On a standard analysis, "contraction" to "wanna" is blocked by some…

Teachers and parents intuitively judge the 'level' of the child and the 'level' of the text and try to match them; they know that overestimation or underestimation of either will be met with restlessness or boredom. In this way, they have an empirical understanding of Vygotsky's ZPD--the zone of proximal development he envisioned as measuring the…

Mixed languages like Media Lengua incorporate grammar from one source language (here, Quichua) but lexicon from another (here, Spanish). Due to their linguistic profile, they provide a unique window into bilingual language usage and language representation. Drawing on sociolinguistic, structural and psycholinguistic perspectives, the current…

The usage-based theory highlights the important role of linguistic input in language acquisition, and assumes that syntactic representations could be entrenched through usage or exposure. In the present study, we used the event-related potential technique to investigate the long-term effect of input training on second language (L2) syntactic…

One of the most researched challenges in learning Spanish is the acquisition and use of the past aspect, namely, the preterit and imperfect. L2 learners encounter this challenge due to differences in how native English and Spanish speakers view past events. Numerous studies on the Spanish past aspect have analyzed L2 learners' past aspectual…
