Young children struggle more with mapping novel words onto relational referents (e.g., verbs) compared to non-relational referents (e.g., nouns). We present further evidence for this notion by investigating children's extensions of noun-noun compounds, which map onto combinations of non-relational referents, i.e., objects (e.g., "baby"…

Research Findings: To extend findings that are mainly based on North American studies with English speakers, we studied 989 Chilean mothers from households of low socioeconomic status and their prekindergarten children, posing 2 questions: (a) Do mothers' self-reported practices about literacy development predict early literacy outcomes over and…

Generic sentences (e.g., "Birds lay eggs") convey generalizations about entire categories and may thus be an important source of knowledge for children. However, these sentences cannot be identified by a simple rule, requiring instead the integration of multiple cues. The present studies focused on 3- to 5-year-olds' (N = 91) use of…

Young children learning English are biased to attend to the shape of solid rigid objects when learning novel names. This study seeks further understanding of the processes that support this behavior by examining a previous finding that three-year-old children are also biased to generalize novel names for objects made from deformable materials by…

Young children's comprehension and overdiscrimination of natural language concepts were examined by asking 2- and 4-year-old children to select pictorial instances of five concrete semantic concepts. Results suggest that young children initially tend to use concept labels in a very restricted manner. (JMB)

Analyzes the overgeneralizations of bilingual children to determine whether the overgeneralizations of Spanish and English monolinguals would differ from those found in the speech samples of Spanish-English bilinguals and to reach a better understanding of speakers' preference for certain affixes and roots. (MES)

The purpose of this study was to investigate children's acquisition of the non-comparative forms of spatial adjectives and to specifically test the following experimental questions: (1) Are positive-pole terms, or those such as "big," which indicate extent along a dimension, acquired earlier than negative-pole terms? (2) Does…

Linguistic and cognitive competencies of preschoolers were revealed by interviewing them about routine activities. It was found that freeing preschoolers' speech from constraints inherent in talking about the immediate context results in their demonstrating control over a variety of language-related skills that are generally assumed to be beyond…

From the standpoint of transformational grammar, this experimental work evaluates the extent to which children choose or fail to generalize their rules for the placement of the negative particles "not" and "n't." The subjects were eight three- and four-year-olds of middle-class background who had been producing sentences with…

Three stages of the developing second language of a 3;9-3;11 year-old English-speaking child in an Urdu speech milieu were examined and compared with findings that have been accumulated about the order and process of first language acquisition. The study showed that in the development of many syntactic and morphological features the child used…

Preschoolers' ability to understand grammatical relations in passives and to generalize was studied using animate referents. Three- to five-year-old children were taught to produce passive sentence descriptions of events in which animacy of the actor and acted-on object were varied. After pretesting to determine passive sentence comprehension, the…
