When assessed for speech/language development, 31 children (age 1-12) fitted with endotracheal tubes for more than 3 months beginning by age 13 months showed overall language functioning within normal limits and commensurate with cognitive ability. However, a pattern of expressive language disability was noted in the oldest group. (Author/JDD)

Reports a study of two- and three-year-olds' acquisition of complex sentences with perception and epistemic verbs that took a second verb in their complements. Complement types, complementizer connectives, and the discourse contexts in which complementation occurred were specific to individual matrix verbs. (Author/CB)

Analysis of mothers' pragmatic language use and children's language levels during free play sessions suggested that a mother-driven, direct influence model may be inappropriate for many mother speech-child language development relationships and points to the feasibility of child- and mother-driven explanatory models for indirect relationships.…

A longitudinal study of four 17- to 33-month-olds revealed that their linguistic selection at the one-word stage was governed by principles of informativeness, while the two-word stage was characterized by new, or a combination of new and old, information. (Author/CB)

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…

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)

Reports a case study of a British 2-year old that shows a stage in syntactic development without a subject agreement protection but with a tense phrase. A sharp contrast in use of verb forms suggests that the child had left the Optional Infinitive stage and entered a transitional stage, where the major development is that the status of the bare…

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…

Explores the possibility that particular properties of how number words are used within sentences inform children of the semantic class to which they belong. Analysis of transcripts of the spontaneous speech of three children and their parents suggests that the relevant cues are available as input in parents' speech to children and that children…

Investigates acquisition of the rhyme using cross-sectional and longitudinal data from 14 English-speaking children between 1- and 2-years of age. Focuses on four questions pertaining to rhyme development that are motivated from current theories of prosodic acquisition. (Author/VWL)

Studied the case of bilingual acquisition across two modalities to examine diverging hypotheses about the types of knowledge underlying early bilingualism. Three children acquiring Langues des Signes Quebecoise and French, and three children acquiring French and English were videotaped over a year while novel and familiar speakers of each child's…

Describes the phonological acquisition of 129 monolingual Putonghua-speaking children, aged 1.6 to 4.6 years. Children's errors suggested that Putonghua-speaking children master four elements of Putonghua syllables in this order: (1) tones; (2) syllable-initial consonants; (3) vowels; and (4) syllable-final consonants. Suggests that the saliency…

Development of children's vocabularies for gender-typed words and communicative actions was investigated longitudinally from 13 to 36 months and in a group of 9.5-month-olds. Vocabularies of gendered words were assessed using lists of adult-rated gender-typed words from the MacArthur-Bates Communicative Development Inventories (CDI; L. Fenson et…

The purpose of study was to investigate the impact of pre-surgical Infant Orthopaedics (IO) on consonant production at 18 months of age in children with Unilateral Cleft Lip and Palate (UCLP) and to compare the consonant production to that of age-matched children without clefts. The first ten children in a consecutive series of 20 with UCLP…

This study investigated the influence of the speaker's experience and addressee's developmental level on baby talk characteristics. A total of 240 mothers of only child infants (l-l8 months) or of children 2-3 years old responded to an Infant or Child Series of drawings with an attached list of sentences. Subjects described situations in drawings,…
