The study investigates the development of English multiword negation, in particular the negation of zero marked verbs (e.g. "no sleep", "not see", "can't reach") from a usage-based perspective. The data was taken from a dense database consisting of the speech of an English-speaking child (Brian) aged 2;3-3;4 (MLU 2.05-3.1) and his mother. The…

We present data on the language of space in Hungarian individuals with Williams syndrome (WS; 19 in the first, 15 in the second study, between 8;0 and 21;11) and a verbal control (VC) group of typically developing (TD; 19 in the first, 15 in the second study, between 3;5 and 10;7) children from: (1) a study of elicited production and comprehension…

Research on the development of efficiency in spoken language understanding has focused largely on middle-class children learning English. Here we extend this research to Spanish-learning children (n=49; M=2;0; range=1;3-3;1) living in the USA in Latino families from primarily low socioeconomic backgrounds. Children looked at pictures of familiar…

This study examines the mental processes involved in children's on-line recognition of inflected word forms using event-related potentials (ERPs). Sixty children in three age groups (20 six- to seven-year-olds, 20 eight- to nine-year-olds, 20 eleven- to twelve-year-olds) and 23 adults (tested in a previous study) listened to sentences containing…

The study evaluated whether durational and allophonic cues to word boundaries are intrinsic to syllable production, and so acquired with syllable structure, or whether they are suprasyllabic, and so acquired in phrasal contexts. Twenty preschool children (aged 3 ; 6 and 4 ; 6) produced: (1) single words with simple and complex onsets (e.g. "nail"…

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 experiments investigated the ability of eight-year old children with poor language comprehension to produce past tense forms of verbs. Twenty children selected as poor comprehenders were compared to 20 age-matched control children. Although the poor comprehenders performed less well than controls on a range of tasks considered to tap…

The relationship between grammatical and lexical development was compared in 233 English and 233 Italian children aged between 1;6 and 2;6, matched for age, gender, and vocabulary size on the MacArthur Communicative Development Inventories (CDI). Four different measures of Mean Length of Utterance were applied to the three longest utterances…

Two experiments investigated the acquisition of English comparative adjective forms, "Adj+er" and "more Adj." In Experiment 1, 72 children, four- and seven-years-old, indicated their preferences for the synthetic or periphrastic comparative form for 16 adjectives in a forced-choice judgement task; their responses were compared to those of a group…

Why are young children's utterances short? This elicited imitation study used a new task--double imitation--to investigate the factors that contribute to children's failure to lexicalize sentence subjects. Two-year-olds heard a triad of sentences singly and attempted to imitate each; they then again heard the same triad singly and again attempted…

This study compares homonym learning to novel word learning by three- to four-year-old children to determine whether homonyms are learned more rapidly or more slowly than novel words. In addition, the role of form characteristics in homonym learning is examined by manipulating phonotactic probability and word frequency. Thirty-two children were…

Investigation of native English-speaking adults' and native Spanish-speaking children's acquisition of noun gender and its function in Spanish revealed significant differences in first- and second-language acquisition, suggesting a developmental progression in acquisition of noun gender for both groups.

Hungarian-Russian bilingual preschoolers, in general, paid more attention to allomorphy than did monolingual Hungarian or Russian peers in interpreting transitive sentences with varying word orders. (Author/CB)

Comparison of maternal speech to three-month-olds between American (N=20) and Japanese (N=20) mother-infant dyads revealed that infant gaze affected the intended functions of maternal speech differently for the two groups. Cultural differences were also seen in the nature of function-form and function-referent relationships. (Author/CB)

Examination of the first 50 words of three blind children revealed that the early vocabulary paralleled that of seeing children in terms of age and speed of acquisition. Differences between the two groups were related to factors which were highly influenced by experience (including visual experience). (Author/CB)
