Children, like adults, use referring expressions to refer to specific objects, events, or people. Research has provided insights into how children use referring expressions and the appearance of forms developmentally (Radford, 1990; Abu-Akel, et al., 2004; Pine & Lieven, 1997). This study examined how three, four, and five year-old children…

The research presented here uses theoretical constructs of formal syntax to account for performance data in agreement production. The phenomenon examined is object interference in French, i.e., incorrect agreement of the verb with the object. In the first experiment, interference is shown to occur in object relative clauses despite the absence of…

This study analyzed German and Nso mothers' auditory, proximal, and visual contingent responses to their infants' nondistress vocalizations in postnatal Weeks 4, 6, 8, 10, and 12. Visual contingency scores increased whereas proximal contingency scores decreased over time for the independent (German urban middle-class, N = 20) but not the…

Grammatical gender is generally considered an early and error-free acquisition in French children. This article first examines how children cope with the gender attribution problem, "i.e.", how they determine the gender of individual nouns. We consider the plausibility and requirements of an account in which tacit phonological assignment rules are…

Act-out and intermodal preferential looking (IPL) tasks were administered to 67 English children aged 2-0, 2-9 and 3-5 to assess their comprehension of canonical SVO transitive word order with both familiar and novel verbs. Children at 3-5 and at 2-9 showed evidence of comprehending word order in both verb conditions and both tasks, although…

As a result of exposure, infants acquire biases that conform to the rhythmic properties of their native language. Previous lexical stress preference studies have shown that English- and German-, but not French-learning infants, show a bias toward trochaic words. The present study explores Spanish-learning infants' lexical stress preferential…

We present a hierarchical Bayesian framework for modeling the acquisition of verb argument constructions. It embodies a domain-general approach to learning higher-level knowledge in the form of inductive constraints (or overhypotheses), and has been used to explain other aspects of language development such as the shape bias in learning object…

Parents' use of conventional versus unconventional labels with their two- (n=12), three- (n=12) and four-year-old children (n=12) was assessed as they talked about objects that were either known or unknown to them. For known objects, parents provided typical conventional labels casually during the conversation. For unknown objects, parents were…

The study examined children's use of verbal -s marking (e.g., he "walks") in two nonmainstream dialects of English, African American English (AAE), and Southern White English (SWE). Verbal -s marking was of interest because there are gaps in the literature about the nature of this structure within and across typically developing children…

Longitudinal research into adult outcomes in autism remains limited. Unlike previous longitudinal examinations of adult outcome in autism, the twenty participants in this study were evaluated across multiple assessments between early childhood (M = 3.9 years) and adulthood (M = 26.6 years). In early childhood, responsiveness to joint attention…

Purpose: This study explores the hypothesis that vocabulary growth can have 2 types of effects in morphosyntactic development. One is a general effect, where vocabulary growth globally determines utterance complexity, defined in terms of sentence length and rates of subordination. There are also specific effects, where vocabulary size has a…

This work investigates the developmental aspects of the duration of point vowels in children with normal hearing compared with those with hearing aids and cochlear implants at 4 and 5 years of age. Younger children produced longer vowels than older children, and children with hearing loss (HL) produced longer and more variable vowels than their…

When faced with a sentence like, "Some of the toys are on the table", adults, but not preschoolers, compute a scalar implicature, taking the sentence to imply that not all the toys are on the table. This paper explores the hypothesis that children fail to compute scalar implicatures because they lack knowledge of relevant scalar alternatives to…

This paper reports the experiences of 150 children and six primary teachers when active learning pedagogies were introduced into the first year of primary schools. Although active learning increased the amount of talk between children, those from socio-economically advantaged homes talked more than those from less advantaged homes. Also,…

Two studies illustrate the functional significance of a new category of prelinguistic vocalizing--object-directed vocalizations (ODVs)--and show that these sounds are connected to learning about words and objects. Experiment 1 tested 12-month-old infants' perceptual learning of objects that elicited ODVs. Fourteen infants' vocalizations were…
