Variations in the amount and nature of early language to which children are exposed have been linked to their subsequent ability (e.g. Huttenlocher, Haight, Bryk, Seltzer & Lyons, 1991; Hart & Risley, 1995). In three computational simulations, we explore how differences in linguistic experience can explain differences in word learning ability due…

Analysis of the free speech of one- to three-year-olds (N=21) found that measures of mean length of utterance (MLU) are positively related to age, are reliable, and can predict grammatical development, although there are identifiable points in the developmental evolution of MLU and MLU-like indices beyond which their reliability and validity have…

Investigates the inconsistencies of personal pronoun production both in production and between production and comprehension in a pronoun-reversing child. (EKN)

Normal and Specific Language Impaired (SLI) children were tested for evidence of the binding domain and orientation properties of their grammars. Results suggest that normal children acquiring English pass through a long-distance binding stage, whereas SLI children behave like very young normal children in requiring the nearest available noun…

This study compared the performance of English-speaking children attending French schools (bilingual group) on phonological awareness tests with same age English-speaking children attending English schools. Results of the study are interpreted to reflect the role of second-language input in phonological awareness. (JL)

Describes and examines three tests using an infant speech identification (ISI) procedure, in which English language environment infants, two- and six-year-old children, and adults were tested for their identification of sounds on a native (voice/voiceless bilabial stop) and a nonnative (prevoiced/voiced bilabial stop) speech continuum. (31…

Various theories of learning for the categories "count noun" and "mass noun" are compared. It is argued that children assign words to these categories on the basis of intuitions arising from perception that are relevant to Macnamara's (1986) definitions of the categories. (39 references) (GLR)

Investigated whether the rate and patterns of pronoun case error were influenced by the composition of an individual pronoun's paradigm. Twenty-nine children ages 2;6 to 4;0 years were audiotaped interacting with their primary caregivers in various settings. Results indicated that 27 children produced case errors. The composition of a pronoun's…

Research on child language acquisition should distinguish between different possible causes of variation and not just attribute variation to individual variation. An alternative analysis using a different methodology can show that children's patterns of acquisition are actually relatively similar. (Author/CB)

Examination of the transition to purposive use of intonation with single words for two infants revealed that both clearly used rising tones to ask questions by 1.5 years of age and demonstrated widespread and gradual grammatical use of intonation. (Author/CB)

Williams syndrome (WS) is often cited as the prime example within developmental disorders of the dissociation of language from other cognitive skills, particularly from visuo-motor skills. This claim has been responsible for the challenges posed by this population to cognitive theories and to models of language acquisition. Two Hebrew-speaking…

We investigated infant precursors of low language scores in early childhood. The sample included 373 probands in 130 monozygotic (MZ) and 109 same-sex dizygotic (DZ) twin pairs in which at least one member of the pair scored in the lowest 15th percentile of a control sample on a general language factor derived from tester-administered tests at…

Phonological awareness is thought to become increasingly analytic during early childhood. This study examines whether the proposed developmental sequence (syllable[right arrow]onset-rime[right arrow]phoneme) varies according to the characteristics of a child's native language. Experiment 1 compares the phonological segmentation skills of English…

Three studies assessing language comprehension of infants and toddlers through a method requiring a minimum of motor movement, no speech production, and differential visual fixation of two simultaneously presented video events provide insight into children's emerging linguistic capabilities and help resolve controversies about language production…

Studies analyzing children's response time to detect word targets revealed that six-year-olds and younger children generally did not show the response time advantage for accented target words which adult listeners show, providing support for the argument that the processing advantage for accented words reflects the semantic role of accent as an…
