This article examines the acquisition of embedded verb placement in Swedish children, focusing on Neg-V and V-Neg order. It is proposed that a principle of economy of movement creates an overuse of V-Neg order in embedded clauses and that the low frequency of the target-consistent Neg-V order in child-directed speech obstructs children from…

Three experiments on structural priming in Mandarin-speaking 5-year-olds were conducted to test the priming as implicit learning hypothesis. It describes a learning mechanism that acts on a shared abstract syntactic representation in response to linguistic input using an equi-biased Mandarin SVO-"ba" alternation. The first two…

This study investigates 2-5-year-old Mandarin-speaking children's interpretation of the disjunction word "huozhe" ("or") in two positions in "ruguo" ("if")-conditional statements, i.e., in the antecedent clause versus in the consequent clause. The findings from three experiments show that the meanings…

Two recent proposals link the use of nonagreeing "don't" to the Root Infinitive (RI) Stage. Guasti & Rizzi (2002) argue for a misset parameter involving how agreement is spelled out. Schütze (2010) proposes that Infl is underspecified in child language and that "do" surfaces to support the contracted clitic/affix…

We report the results of two studies that investigate the factors contributing to non-native-like ability in child and adult heritage speakers by focusing on oral production of Differential Object Marking (DOM), the overt morphological marking of animate direct objects in Spanish. In study 1, 39 school-age bilingual children (ages 6-17) from the…

The induction problems facing language learners have played a central role in debates about the types of learning biases that exist in the human brain. Many linguists have argued that some of the learning biases necessary to solve these language induction problems must be both innate and language-specific (i.e., the Universal Grammar (UG)…

We present data from an artificial language domain that suggest new contributions to the theory of syntactic triggers. Whether a learning algorithm is capable of matching the achievements of child learners depends in part on how much parametric ambiguity there is in the input. For practical reasons this cannot be established for the domain of all…

The present article examines the effect of variable input on the acquisition of plural morphology in two varieties of Spanish: Chilean Spanish, where the plural marker is sometimes omitted due to a phonological process of syllable final /s/ lenition, and Mexican Spanish (of Mexico City), with no such lenition process. The goal of the study is to…

This article presents the results of four studies exploring the acquisition of the language-specific syntactic and semantic properties of multiple interrogatives in English, Russian, and Malayalam, languages that behave differently with respect to the syntax and semantics of multiple interrogatives. A corpus analysis investigated the frequency of…

Researchers have long debated the mechanisms underlying the learning of syntactic structure. Of significant interest has been the fact that passive constructions appear to be learned earlier in Sesotho than English. This paper provides a comprehensive, quantitative analysis of the passive input Sesotho-speaking children hear, how it differs from…

While L1 transfer and L2 learnability have been studied extensively in the domain of syntax and the syntax/semantics interface, purely semantic phenomena have received little attention in the L2 literature. This paper presents two experiments examining the relative scope assigned to disjunction and negation by English-speaking learners of Japanese…

This article reports on an experimental investigation of knowledge of distributivity in nonnative (L2) Japanese learners whose first language (L1) is English or Korean. The availability of distributive scope in Japanese is modulated by word order and the semantic features of quantifiers. For English-speaking learners, these subtle interpretive…

Article omission is known to be a feature of early grammar, although it does not affect all child languages to the same extent. In this article we analyze the production of articles by 12 children, 4 speakers of Catalan, 4 speakers of Italian, and 4 speakers of Dutch. We consider the results in the light of (i) the adult input the children are…

In this article I provide evidence that despite frequently cited differences between child first language (L1) and adult second language (L2) speakers in overt behavior (performance) during grammatical development, the nature, source, and limits of implicit knowledge (competence) in native and second language grammars are equivalent (i.e., they…
