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…

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…

Many recent models of language comprehension have stressed the role of distributional frequencies in determining the relative accessibility or ease of processing associated with a particular lexical item or sentence structure. However, there exist relatively few comprehensive analyses of structural frequencies, and little consideration has been…

Orphanage life places children at risk of developmental delay, particularly with regard to speech and language acquisition. The aim of this study was to evaluate opportunities for children in an orphanage in South Africa to acquire communicative competence, by examining adult-child and child-child interactions and by evaluating the structure and…

Early language comprehension may be one of the most important predictors of developmental risk. The need for performance-based assessment is predicated on limitations identified in the exclusive use of parent report and on the need for a performance measure with which to assess the convergent validity of parent report of comprehension. Child…

This longitudinal study explored how gestures changed with with respect to speech as two children progressed from producing single words to producing two-word combinations. Two girls were followed from the production of only single words to their first production of two-word combinations. One child was followed from 14.5 to 18 months; the second…

This paper discusses empirical findings from the first language acquisition of Mandarin Chinese suggesting that certain properties of the logical form of natural language are not learned from experience. These unlearnable properties appear to manifest themselves in the child's linguistic knowledge as soon as prerequisite conditions are met.…

Computer programs for linguistic analysis of language samples from bilingual children were surveyed in order to evaluate their usefulness. Eight programs which could be implemented on the UCLA IBM 370/3033 computer were considered. It was determined that the Computer Assisted Language Analysis System was the most promising in terms of capabilities…

A fundamental concept of generative phonology stating that related morphemes have unique phonological representations is criticized. It is argued that more morphologization of phonological rules is needed to explain morphophonemic changes. (Available from North-Holland Publishing Co., P. O. Box 211, Amsterdam, The Netherlands.)

A study to investigate the development of children's ability to relate concepts and thus understand metaphors by examining their performance on three concept-relating tasks is reported. Abstract-metaphoric, concrete-metaphoric, and literal taxonomic relationships were embedded in an analogy-like binary choice task. In this type of task, the…

The cognitive processes involved in a child's interaction with the linguistic environment are discussed. Specifically, the general cognitive processes involved in outputting long spans of connected utterances are examined. Narrative data are classified into three developmental levels: the procedural phase, where the linguistic output is generated…

Although Mandarin Chinese is a topic-prominent language, it is shown that young children acquiring Chinese as their first language access the concept of grammatical subject as well as that of topic. A total of 95 children aged 2-5 years acquiring Mandarin Chinese as their first language were tested on sentences involving equi-constructions. It was…

The transition from pre-linguistic to linguistic communication was investigated in the acquisition of pronouns in American Sign Language (ASL). Data were obtained from a congenitally deaf child learning ASL as a first language from deaf parents. Longitudinal data from the age of 6 months to 2 years and pronoun elicitation task data were analyzed.…

The progression through the developmental stages of the acquisition of interrogatives was analyzed. Data on use of the "what" interrogative were collected during play sessions from eight children at six-month intervals from the ages of 1;6 to 3 years. More than 2,400 children's interrogatives were recorded. It was demonstrated that…
