Results of a longitudinal study of seven children under age two suggest that variation in children's early word combinations can be explained in terms of different routes to multiword speech; and a strategy involving the breaking down of originally unanalyzed phrases may be used by all children in varying degrees.

The MacArthur Communicative Development Inventories (CDIs) represent a breakthrough in measuring early language production. Nevertheless, the CDIs' word comprehension component may not be a valid measure, because parents report too high a word comprehension ability for their children. Suggests that administering the CDIs to parents in an interview…

This study shows that the noun bias in early vocabularies rests only in part on the acquisition of object names. An analysis of vocabulary composition from 45 children at I;8 indicates that more nouns are acquired than all other word classes but that only about half of the nouns acquired are the names of basic level object classes (BLOCs).

Twelve two year olds were taught novel count nouns for related but unfamiliar objects. Children's interpretation of the relations between the nouns was mediated by the similarity of the objects, a result that suggests that, by age two, children have the conceptual and lexical abilities necessary for establishing hierarchical relations.

This study explored effects of training six mothers to use focused stimulation to teach specific target words to their toddlers with Down syndrome. Following treatment, trained mothers used the focused stimulation technique more often than mothers in the control group. Concomitantly, their children used target words more often, as reported by…

This study assessed the influence of a 10-week parent-child intervention group on the vocabulary development of 10 late-talking toddlers. Results demonstrated the efficacy of the focused stimulation approach in increasing overall and target vocabulary acquisition. Parents reported satisfaction with the program in terms of the child's vocabulary…

This pilot study examined, from a dynamic systems perspective, changes in maternal/child discourse behaviors across repeated readings of a storybook. Four Caucasian children (2 boys, 2 girls), ranging in age from 2 years 7 months to 2 years 10 months, were videotaped reading unfamiliar storybooks with their mothers. The videotapes were…

Case studies are presented for two early talkers, one of whom represents a striking dissociation between vocabulary size and mean length of utterance. Each child is compared to controls in the same language stage, and the data are examined to determine whether the dissociation is best characterized as one between grammar and semantics, or a…

Three experiments introduced 2- and 3-year-olds to novel adjectives either using full noun phrases and describing multiple familiar objects sharing a salient property or describing nouns of vague reference. Found that both groups mapped novel adjectives onto object properties when given taxonomically specific nouns with rich referential and…

The development of a new parent report instrument, Inventario del Desarollo de Habilidades Communicativas, is reported and 5 studies carried out with the instrument for 328 children aged 8 months to 2 years/7 months are presented. Among the findings are similar trajectories of development for Spanish- and English-speaking children and for children…

Explored the interplay between gestures and words in the early vocabulary of 12 normally developing Italian children at 16 and 20 months of age. Focused on spontaneous production of verbal and gestural types and tokens to assess the diversity and semantic content of the verbal and gestural vocabularies. Results indicated that gestures were used…

This study, involving three toddlers with language impairments, evaluated effectiveness of a lexical facilitation strategy designed to increase the salience or informativeness of target objects relative to other objects and actions in the context. Complications in employing the experimental task in intervention settings are discussed, along with…

The effectiveness of two language treatment methods, modeling versus modeling plus evoked production, in promoting productive vocabulary in three late-talking toddlers was compared. Two subjects differed as to which particular treatment method was associated with better performance. Neither treatment method was effective for the third subject.…

Word learning by young children is viewed as a problem deriving from the use of forms of discourse texts. Uses of causal and temporal terms in private speech by a child studied longitudinally from 1;9 to 3;0 are analyzed from this perspective. (Contains 38 references.) (JL)

Assessed long-term predictive validity of the MacArthur Communicative Development Inventories: Words and Sentences (CDI:WS) for children's expressive and receptive vocabulary development. Sixty-one New Zealand children were assessed with a New Zealand version of the CDI, and with the Expressive Vocabulary Test and Peabody Picture Vocabulary…
