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…

Purpose: The current study was designed to (a) describe average hourly Language Environment Analysis (LENA) data for preschool-age Spanish--English bilinguals (SEBs) and typically developing monolingual peers and (b) compare LENA data with mean length of utterance in words (MLUw) and total number of words (TNW) calculated on a selected sample of…

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…

An eye-tracking study explored Korean-speaking adults' and 4- and 5-year-olds' ability to recover from misinterpretations of temporarily ambiguous phrases during spoken language comprehension. Eye movement and action data indicated that children, but not adults, had difficulty in recovering from these misinterpretations despite strong…

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)

Three- to nine-year-olds' (N=80) post-exposure production of regular and irregular suffixes indicated that subjects found it easier to learn a regular suffix when they heard it used with phonetically similar base forms. Subjects were more likely to overgeneralize the regular suffix to irregular forms when they had heard it used in conjunction with…

A study examined the manner in which 10 specifically language-impaired children and their linguistically normal chronological age-matched peers repaired overlapping speech. Conversational samples from each student were elicited by an adult examiner. (26 references) (Author/CB)

Describes a model that allows children to control the complexity of the speech they hear within conversations on a moment-to-moment basis. Experimental and observational data clearly delineate the reciprocal nature of how speakers "fine-tune" their speech to listeners. The effects of child-directed speech on language development are discussed.…

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…

Probes the relation between speech perception and reading ability of children who were good or poor readers. Results indicate that reading-related perception differences were especially marked in a comparison of actual and predicted discrimination scores. Identification slope and phoneme boundary differences between reader groups were found as…

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…

Studies of (TD) and (ING) in King of Prussia (Pennsylvania) families show that children have matched their parents' patterns of variation by age seven, before many categorical phonological and grammatical rules can be established. Some dialect-specific and socially marked constraints are acquired before constraints with general articulatory…

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…
