Studies on the acquisition of Spanish as a first language do not agree on the patterns and factors relevant for coda development. In order to shed light on the questions involved, a longitudinal study of coda development in Northern European Spanish was carried out to explore the relationship between accuracy, markedness and frequency. The study…

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…

The study aims to account for the distribution of finite versus non-finite verbs during a developmental period when children use both types of verb forms in contexts requiring finiteness. To meet this goal, longitudinal samples from three Hebrew-acquiring children (aged 1;4-2;6) are examined from the onset of verb production and across the…

Combinatorial abilities in language and elicited symbolic play were compared in a longitudinal study of 30 children at 20 and 28 months. In addition, multivariate analyses were used to assess the stability of individual differences. Generally, different symbolic play variables contributed unique explained variance to different language variables.…

Observation of five infants' vocalizations during their first 30 weeks showed that hearing impaired infants displayed different language patterns than normally hearing infants. Developmental differences in vocal activity were observed by six weeks, suggesting that hearing impaired infants may differ from unimpaired infants earlier than has been…

An investigation of the nature of one, 2-year-old child's imitative competence in using the modal auxiliary system of English (using "will" and "can") during two periods two months apart. (ED)

Analyzes a child's use of word-level phonological constraints in multi-word utterances. The selection and avoidance patterns and modifications of adult forms indicated the presence of a syllable sequencing constraint that governed grammar and word combinations. (Author/CB)

This study examined the effects of being born very preterm on children's early language development using prospective longitudinal data from a representative regional cohort of 90 children born very preterm (gestational age less than 33 weeks and/or birth weight less than 1,500 grams) and a comparison sample of 102 children born full term…

A longitudinal study of twenty-four (24) Hebrew-speaking mother-infant dyads during discussions of recent events indicated that mothers commented on a small set of events and tended to mark events with exclamations or formulaic expressions that gradually progressed to a true description of events as the children got older. (Author/CB)

In order to determine (1) the major speech characteristics of mothers and fathers and (2) the relationship between parental input and child language development, a longitudinal analysis of parents' input language was conducted during the period in which four first-born children progressed from no words to the stable use of one-word utterances in…

The continuity in development of syllable duration patterns was examined in seven young children as they progressed from preword to multiword periods of vocalization development. Results revealed no systematic increase or decrease in the duration of bisyllables produced by the children as a group, whereas lengthening of final syllables was…

This study reports a replication of an earlier study by Kilbourne and Ginsberg (1980) which indicated the occurrence of a transition from predominantly coacting to predominantly alternating infant-mother vocalization patterns. In addition, the present study examined the modulating influences of nursing activity and mother's focus of attention upon…

Examines whether systematic differences exist in babbling and first words of infants from different language backgrounds (English, French, Japanese and Swedish) and asks whether differences result from the phonetic structure of the languages. Statistically significant differences discerned in the babbling phonetic selection indicates that phonetic…

Video-analysis was used to investigate the transition from coacting to alternating patterns of infant-mother vocalizations in this longitudinal study of one infant. In addition to investigating the transition and its developmental implications, the relationship between the temporal patterning of kinesic and vocal behaviors was studied. The study…

Reports results of a longitudinal study of the acquisition of first words by 18 infants. Strategies used in word acquisition and environmental variables related to language development were investigated. Results were analyzed in terms of an interaction model of the language-learning process. (DP)
