This cross-linguistic comparison of metalinguistic development in French and English examines early ability to manipulate derivational suffixes in oral language games as a function of chronological age, receptive vocabulary, and year of schooling. Data from judgment and production tasks are presented for children aged between 5 and 8 years in…

Purpose: The aims of this article are twofold: (a) to offer a set of recommended measures that can be used for evaluating the efficacy of interventions that target spoken language acquisition as part of treatment research studies or for use in applied settings and (b) to propose and define a common terminology for describing levels of spoken…

It has been repeatedly shown that when asked to identify a protagonist's false belief on the basis of his false statement, English-speaking 3-year-olds dismiss the statement and fail to attribute to him a false belief. In the present studies, we tested 3-year-old Japanese children in a similar task, using false statements accompanied by…

In gender-marking languages, the gender of the noun determines the form of the preceding article. In this study, we examined whether French-learning toddlers use gender-marking information on determiners to recognize words. In a split-screen preferential looking experiment, 25-month-olds were presented with picture pairs that referred to nouns…

This study explores the extent to which bilingual speakers in stable bilingual communities become fully bilingual in their two community languages. Growing evidence shows that in bilingual communities in which one language is very dominant, acquisition of the dominant language may be quite unproblematic across sub-groups, while acquisition of the…

Foreign language learning contrasts with native language development in two key respects: It is unreliable and it is nonconvergent. At the same time, it is clear that foreign languages are languages. The fundamental difference hypothesis (FDH) was introduced as a way to account for the general characteristics of foreign language learning. The FDH…

Recent research has indicated that conceptual development in a specific domain may not be independent of the way it is mapped linguistically. We explore this claim in the semantic domain of evidentiality by considering various sets of data from Turkish-speaking children between one and a half to six years. We present evidence for (1) the…

Before they are three years old, most children have started to build coherent discourse. This article focuses on one important linguistic device children have to learn: connectives. The main questions are: Do connectives emerge in a fixed order? And if so, how can this order be explained? In line with Bloom "et al." (1980) we propose to explain…

The central question underlying this study revolves around how children process co-reference relationships--such as those evidenced by pronouns ("him") and reflexives ("himself")--and how a slowed rate of speech input may critically affect this process. Previous studies of child language processing have demonstrated that typical language…

Purpose: To examine the role of phonotactic probabilities at the onset of language development, in a new language (Dutch), while controlling for word position. Method: Using a nonword imitation task, 64 Dutch-learning children (age 2;2-2;8 [years;months]) were tested on how they imitated segments in low- and high-phonotactic probability…

Relative clauses have been implicated alternately as a strength and a weakness in the language of people with Williams Syndrome (WS). To clarify the facts, an elicited production test was administered to 10 people with WS (age 10-16 years), 10 typically developing children (age 4-7 years), and 12 typically developing adults. Nearly every WS…

Background: This research explored the relative impact of demographic, cognitive, behavioural, and psycholinguistic factors on vocabulary development in two-year-old children. Methods: Two hundred and thirty-two children (24-30 months) were tested on expressive and receptive vocabulary, cognitive development, word learning and working memory…

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…

This study examined associations between peers' expressive language abilities and children's development of receptive and expressive language among 1,812 four-year olds enrolled in 453 classrooms in 11 states that provide large-scale public pre-kindergarten (pre-k) programs. Higher peer expressive language abilities were positively associated with…

This study examines the effectiveness of an output practice, i.e., Chinese-to-English translation, on promoting noticing and acquisition of a type of grammatical form, i.e., lexical phrases. It is confirmed that output is vital in facilitating learners' noticing and acquisition of the targeted linguistic forms.
