This study investigated the relation between lexical development and the production of prosodic prominence in disyllabic babble and words. Monthly recordings from nine typically developing Belgian-Dutch-speaking infants were analyzed from the onset of babbling until a cumulative vocabulary of 200 words was reached. The differentiation between the…

This paper argues for broader consideration of children's language production systems and, in that context, describes research on children's planning of syntactic structures. The research presented here measures non-fluency patterns in elicited utterances of varied syntactic type. We describe and interpret several regularities in these patterns…

The early development of vocalic and consonantal production in Mandarin-learning infants was studied at the transition from babbling to producing first words. Spontaneous vocalizations were recorded for 24 infants grouped by age: G1 (0 ; 7 to 1 ; 0) and G2 (1 ; 1 to 1 ; 6). Additionally, the infant-directed speech of 24 caregivers was recorded…

Analysis of speech samples from British female adults (N=8) revealed that the subjects increased vocal pitch when addressing young children, but not as much as previously studied North American subjects did. Pitch increases were more commonly observed in free speech than in reading-aloud conditions. (23 references) (Author/CB)

Investigation of French mothers' (N=6) use of pronouns to refer to their infants during free play showed that third- and first-person pronouns occurred more often in the context of affect-oriented activities than in goal-directed activities. Second-person pronoun usage occurred more frequently in goal-directed activities. (Author/CB)

Argues that the measures of content and style of maternal talk used by the Murray and Trevarthen (1986) study of temporal patterning during vocal engagements did not directly indicate the ways in which the behaviors of the partners (mothers and infants) were combined on a moment-to-moment basis. (Author/CB)

Investigation of the communicative functions of pitch direction and range in one-year-olds (N=2) indicated that use of pitch among infants may be related to a period where communicative intentions are clearly defined, but language is not yet available. A higher pitch was observed among infants who made repeated requests for objects as opposed to…

Analysis of longitudinal data from four Mexican-American children to explore two aspects of the acquisition of Spanish word stress indicates that children approach such learning unbiased toward any particular stress type. Children's attention to phonetic or semantic aspects of normatively unstressed syllables leads them to shift stress to that…

Examines the phonetic patterns and linguistic development of an infant who was tracheostomized during the period that infants normally begin to produce syllabic vocalization. It was found that the infant had developed only a tenth of the canonical syllables expected in normally developing infants, a small inventory of consonant-like segments, and…

Analysis of a complete set of word-forms produced by a one-year-old at the one-word stage found that the data showed little phonetic variability and that phonological development during the period studied (about one year) was qualitatively continuous with subsequent development. (Author/CB)

A longitudinal study examined two-year-olds' acquisition of the English auxiliary system after a six-week exposure to additional auxiliary input in varying sentence contexts. Results indicated that subjects did not significantly differ from a baseline group that did not receive additional input. (Author/CB)

Microanalyses of unstructured videotaped interactions of three mother-infant dyads revealed dramatic shifts in dyadic vocalization patterns from primarily overlapping to primarily alternating. These results suggest that the emergent patterns reflect increased potential for coordination within the dyad, which may be capitalized on by mother and…

Similarity neighborhoods for words in young children's lexicons were investigated using three computerized databases. Results revealed that words in five- and seven-year-olds' lexicons have many fewer similar neighbors. (Author/CB)

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.…
