This study constitutes the beginning of a longitudinal investigation of phonological development of four children from birth to 2 years. Little variation was found in mean fundamental frequency. Duration, within-utterance range and variability did show developmental change. (RM)

A study of a comprehensive work by Bronckart on Piaget and his theories regarding child language. The strengths and weaknesses of the "young school at Geneva" are analyzed. Questions with implications for further research are raised. (Text is in French.) (AMH)

THE AUTHOR FEELS THAT TO APPROACH CHILD LANGUAGE TRANSFORMATIONALLY IS TO USE A TECHNIQUE SUITED TO PROVIDING ADDITIONAL INSIGHT INTO A WELL-KNOWN LANGUAGE FOR TREATING AN UNKNOWN, OR AT BEST LITTLE KNOWN LANGUAGE. SHE MAKES THE FOLLOWING CRITICISMS OF TRANSFORMATIONAL ANALYSIS OF CHILD LANGUAGE--(1) NOTHING CAN BE DIRECTLY INFERRED WITH REGARD TO…

Sex differences in language development were studied. Protocols from 54 children, aged 2;0 to 4;2, were analyzed with Mean Length of Utterance (MLU) as the independent variable. When MLU's reached 3.75 to 4.0, differences began to favor girls. Results are discussed in terms of a social learning model and a cognitive model. (Author)

This paper represents a partial condensation of the results of a study covering 14 months in a Russian-speaking child's phonological development. Evidence supports a theory of phonological acquisition formulated by Olmsted (1971), and offers detailed information on the child's acquisition of specific phones. (CHK)

Describes a study to determine: (1) the relationship between age and mean length of utterance measured in morphemes (MLU) in a group of normally developing two- and three-year-old chidren; (2) the standard error of MLU; (3) the relationship between MLU and age; and, (4) the ability of MLU to predict children's grammatical development. (SED)

Studies show many experts believe that there is no significant difference between the age when a boy begins to communicate verbally and when a girl begins. (SW)

A research project was aimed at measuring the relationship between infant vocalizations and linguistic development and determining the feasibility of using infant vocalizations as a predictor of later psychological and intellectual status. However, a method was needed to analyze the vocalizations of infants. This report describes a method used to…

Speech discrimination by 12 children aged about 1 1/2 to 3 1/2 years was tested, using the discrimination learning procedure of Shvachkin's 1948 Russian study. Recent work on the acquisition of syntax and semantics shows an ordered acquisition for linguistic items; this pilot study was to test whether the ability to discriminate between consonants…

Indicates that 18- to 20-month-old infants can detect the correspondence between auditorially and visually perceived speech; that is, they manifest some of the components related to lip-reading phenomena in adults. This demonstration of the bimodal perception of speech in infancy has important implications for social, cognitive, and linguistic…

Imitation in the speech of the child serves at least three functions in the development of linguistic competence. Imitation provides auditory feedback for phonological and morpho-syntactic accuracy, produces a model for verification and/or clarification by speakers, and "makes time" for the processing and acquisition of information. Beyond these…

A study was undertaken to determine whether children in early periods of language development use stress with any regular patterns, and if so, on what the patterns are based. The subjects were five children aged 21-29 months, MLU between 1.3 and 2.4. Tape recordings were made during play sessions with each child. Two-word utterances that could be…

Up to the present, no studies have been done in the area of child language in Mexico. The Center of Linguistic and Literary Studies of the Colegio de Mexico carried out an empirical investigation of the language of six- to seven-year-old Mexican children. This paper presents, in preliminary form, some partial results of the investigation,…

THE LITERATURE ON INTELLECTUAL DEVELOPMENT APPEARS TO ATTRIBUTE TO THE YOUNG CHILD A HIGH LEVEL OF LINGUISTIC DEVELOPMENT AND A RELATIVELY LOW LEVEL OF DEVELOPMENT IN OTHER COGNITIVE SPHERES. IN AN ATTEMPT TO RESOLVE THIS DISCREPANCY, THE AUTHOR ADVANCED THE HYPOTHESIS THAT THE DESCRIPTIONS OF LANGUAGE DEVELOPMENT ARE BASED ON AN ANALYSIS OF THE…
