A grandmother attempts to teach her four-year-old granddaughter the multiplication tables using simple repetition, but they repeatedly start over at 'three fives'; the child keeps coming up with 'thirty-five'. We consider three possible explanations: self-perpetuating frequency of behavior, saliency of memory and Vygotsky's next or proximal zones…

Previous work suggests that key factors for replicability, a necessary feature for theory building, include statistical power and appropriate research planning. These factors are examined by analyzing a collection of 12 standardized meta-analyses on language development between birth and 5 years. With a median effect size of Cohen's d = 0.45 and…

Teachers and parents intuitively judge the 'level' of the child and the 'level' of the text and try to match them; they know that overestimation or underestimation of either will be met with restlessness or boredom. In this way, they have an empirical understanding of Vygotsky's ZPD--the zone of proximal development he envisioned as measuring 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…

Despite the growing body of integrationist literature on the study of language and on a wide range of language-related fields of inquiry, there is as yet no integrationist investigation of the field of language acquisition. This paper argues for the need of an integrationist study of what children learn about language and of how they learn it.…

Parents and child care personnel in English-dominant parts of the world often express misgivings about raising children bilingually. Their concerns are based on the belief that dual language learning during the infant-toddler stage confuses children, delays their development, and perhaps even results in reduced language competence. In this…

Little research has been conducted on the development of suprasegmental characteristics of vocalizations in typically developing infants (TDI) and the role of audition in the development of these characteristics. The purpose of the present study was to examine the longitudinal development of fundamental frequency (F[subscript 0]) in eight TDI and…

Two experiments are reported investigating young children's comprehension of linguistic reference to past and future times. Available from Plenum Publishing Corp., 227 W. 17th St., New York, NY 10011. (Author/RM)

Describes the acquisition of a set of nonverbal intentionally communicative behaviors for six preverbal infants followed longitudinally. Results show a trend for a set of communicative intentions to emerge in the following sequence: (1) protesting, (2) request for action, (3) request for object, (4) comment on action, (5) comment on object, and…

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…

In the earliest studies of child language, attention was given to language production as utterances of sound. Association of language with meaning followed as language development and the relationship between language and thought gained serious recognition in the study of child development. The traditional societal view of "a child should be seen…

Two nonce-word studies examined German-speaking children's productivity with the "Perfekt" (present perfect) from 2;6 to 3;6. The German "Perfekt" consists of the past participle of the main verb and an inflected form of an auxiliary (either "haben" "have" or "sein" "be"). In Study 1, nonce verbs were either introduced in the infinitival form, and…

Two Japanese universities are undertaking a research program in child language by studying children's verbal and nonverbal development, sponsoring lectures on child language and holding an annual symposium on related subjects. (CK)

This investigation explored the conversational practices and conversational rule-conformity of children aged four, six, and eight. Procedures included observation of the conversational behavior of children in classroom interaction among peers and a controlled laboratory investigation of the conversations of 18 children, of varying age levels, who…

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)
