Children often produce nonadult responses to sentences with the focus operator only, such as "Only the cat is holding a flag." For example, children often accept this sentence as a description of a situation in which a cat holds a flag and a duck holds both a flag and a balloon. One proposed analysis, by Paterson, Liversedge, Rowland & Filik…

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…

This study investigates the acquisition of the discourse/pragmatic notion of topic, based on an experimental task eliciting topic vs. focus subjects. In spoken French, these are obligatorily realized as dislocated vs. nondislocated noun phrases. The results provide overwhelming evidence for the early mastery of topic, even by the youngest children…

Can second language (L2) learners acquire a grammar that allows a subset of the structures allowed by their native grammar? This question is addressed here with respect to acquisition of phonotactics. On the assumption that the L2 initial state equals the native grammar's final state, learnability theory would predict that a lack of negative…

I describe the results of an experiment that bears on how children learn the lexical and syntactic properties of abstract verbs ("seem," "try") in order to distinguish the subclasses of raising ("seem") and control verbs ("try"). Previous research suggested that an inanimate subject in certain contexts leads children to suppose that the subject…

This study investigates the potential incomplete acquisition of binding interpretations in Korean-English bilinguals by asking whether and how the majority language of these bilinguals (English) influences their family or heritage language (Korean), especially when exposure to and use of English starts very early. The experiment tested the…

This article investigates the acquisition of the focus particle "auch" "also" by German-learning children. We report data from spontaneous and elicited production of utterances with the focus particle "auch" by 1- to 4-year-olds complementing earlier findings of a delayed production of the unaccented "auch" compared to the accented one. But in…

In the 1980s, researchers in child language devised several new experimental techniques to assess children's emerging linguistic competence. Innovations in methodology were needed to bridge the apparent gap between the expectation of rapid language acquisition, based on linguistic theory, and the protracted acquisition that was being witnessed…

Passives has been the focus of much research in language acquisition since the 1970s. It has been clear from this research that young children seldom produce passives spontaneously, particularly "long" or "full" passives with a by-phrase; and they usually perform poorly on experimental tests of the comprehension of passives, especially passives of…

This article examines noun-drop constructions in French-speaking children. French being intermediate between English (which rarely allows noun-drop) and Spanish (which freely allows it) with respect to the richness of their respective morphological systems, it provides a fertile testing ground for various agreement-based analyses of noun-drop. We…

We show that 4-year-olds assign the correct interpretation to antecedent-contained deletion (ACD) sentences because they have the correct representation of these structures. This representation involves Quantifier Raising (QR) of a Quantificational Noun Phrase (QNP) that must move out of the site of the verb phrase in which it is contained to…

We demonstrate a U-shaped developmental trajectory in the interpretation of scopally ambiguous sentences, with 4-year-olds and adults, but not 5-year-olds, accessing inverse scope. These results argue against any view that treats 5-year-olds failures as resulting from immaturity of a single mechanism. Instead, we propose that this developmental…

Much developmental work has been devoted to the acquisition of object clitics in French. There is a consensus that in early grammar, children omit object clitics in contexts where an adult would not. Several analyses have been put forth, among which, one proposing a close link between the omission of object clitics and the presence of past…

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…

Languages can differ in fundamental ways with respect to the syntax of sentences with a "missing" direct object. Whereas Japanese and Korean permit null direct objects that are licensed under general discourse conditions (the recoverability of the referent from context) without regard for choice of verb, object ellipsis in English obeys lexical…
