Background: Early intervention for children identified as late talkers (LTs) at the age of 24 months is still a controversial issue in research and clinical routine. Previous studies have shown inconsistent results regarding predictors of early lexical deficits on school-age outcomes of late-talking toddlers. Methods: In a five-wave follow-up…

In this longitudinal investigation of the emerging grammar of seven children, differences in linguistic acquisition were observed. Analyses revealed two distinct styles of syntactic acquisition that appeared to be sex- and speed-related with specific ties to particular utterance types and grammatical-relational specification.

Presents data from a longitudinal investigation concerning the development of language and communicative skills in infants suffering from focal brain injury in the pre- or perinatal period. Phonological analyses of babbling and first words are focused upon, as well as parental reports of the use of gestures for communicative purposes, word…

A longitudinal study examining the role of imitation on children's lexical acquisition is discussed here. Findings did not support the view that imitation may enable new lexical items to be acquired, and it is noted that other functions of imitation in language acquisition should be explored. (CHK)

This study investigated whether mothers' responses to their infants' gestures play a role in their infants' vocabulary development. Eight infants were observed interacting at home with their mothers on 2 occasions, when the infants were 10 to 12 months old, and 16 to 18 months old. Videotapes of the observations were transcribed and coded for…

Describes the transition from single to multiple word utterances in one child. The development illustrates the initial dissociation and later coordination of the temporal chaining of elements and meaning relatedness between elements and also the importance of repetition for the change from single-word utterances to meaning-related, multiword…

The ability of young children to communicate at the time they produce their first words was studied, with particular reference to the question of whether children are able to modify their requests depending on the adult's response. The subjects were four children ranging in age from 15 to 18 months; the data were their requests of adults coded…

Reports on an experiment describing the lexical development of a hearing child with a deaf mother and hearing father. Data confirm previous findings that (1) sign emerges before spoken word, (2) acquisition stages are similar in ASL and spoken English, and (3) the child initially develops one lexical system. (Author/AM)

This study investigated the role of gesture in communication development. Gestural categories, based on communicative function, were identified from longitudinal videotapes of one mother-child pair. The videotapes were made weekly or bi-weekly from the time the child was 13 months of age until she was 42 months of age. The results of the study…

The study reports quasilongitudinal data on 10 children at 2:0 and 2:5, and another 10 children at 2:9 and 3:3. The analysis included word-initial and word-final phonetic inventories of consonant singletons and clusters and a summary of the relative frequency of seven word shapes. (Author/JDD)

Production data from a longitudinal study of seven children in their first attempts to produce words containing fricatives are presented to illustrate how children use four distinct strategies to approach this relatively difficult class of sounds. The strategies are: (1) favorite sounds--an approach used by a subject who seemed to enjoy playing…

A study was conducted to determine whether children give evidence of using any of six comprehension strategies and whether children of same and different ages use different strategies. It was studied how comprehension performance can best be predicted by other facts about the child, including his language and his language input. The six…

A longitudinal study of three children examined the relation between object permanence and language development. (Author/NCR)

By age two, a child begins to form complex sentences by joining two or more sentences or by embedding one sentence into another. Formation of conjoined structures is a simpler process and emerges earlier than that of embedding structures. This paper attempts to answer the following questions: (1) Do children produce or understand embedding…

Children's early utterances were studied to determine whether there are developmental changes in the content, context, frequency, and form of their speech and the degree to which the changes correspond to changes in Piagetian cognitive stage. Twenty children were studied; six were 10 or 11 months old, and the remaining 14 were distributed evenly…
