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)

Discusses the possibility of a neurolinguistic interconnection between the parieto-temporo-occipital junction, semantic aphasis, and cognitive and language development around age seven. (Author/HP)

The present investigation examines three hypotheses concerning the development of temporal coordination of consonant clusters in the speech of children at four age levels. Results reveal that five and seven-year-olds can be separated from older children and adults on the basis of absolute duration of consonants. (CHK)

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)

Compares two types of semantic development (the acquisition of disappearance words and success-failure words) to performance on two types of cognitive tasks (object-permanence and means-ends tasks) among infants. (HOD)

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)

Teachers should not try to impose on children the language of adults, but they can provide models for them to grow naturally into as they become adults. The child knows his language when he comes to school, and the teacher should try to build on what he knows, not blunder into opposition to it. (Author)

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)

The development of early vocalizations was investigated with 13 infants who had Down's syndrome and 27 infants developing normally, at bimonthly intervals from 4 to 18 months of age. Both groups demonstrated increased production of mature syllables over time as well as large variations in vocal development, both within and across groups and across…
