Describes a study showing that mentally retarded children and mentally normal children do not differ fundamentally in cognitive development within the framework of a particular cognitive training. (Text is in French.) (AM)

Children's understanding of the nature of polar terms and comparative terms between the polar opposites is discussed. (CHK)

The purposes of this study include: (1) determining whether socioeconomic status (SES) or verbal ability (VA) exerts greater influence on childrens' performance of Piagetian tasks; (2) devising an instrument for measuring childrens' level of cognitive development which does not depend on verbal ability alone; and (3) adapting materials for teacher…

Observes 75 first- and third-grade children in their classroom mathematics seatwork to test assumptions drawn from Vygotsky's theory about the development of private speech and its relationship to task performance, attention, and motor behaviors accompanying task orientation. (HOD)

Children in grades 1-3 were asked to retell and explain a series of riddles. Ability to recall riddles was not predictive of ability to explain them. Three cognitive factors seemed to determine level of riddle competence. Implications concern the relationship of riddle competence to reading ability and metalinguistic facility. (CHK)

A study was conducted to test whether three, four, and five-year-old children would be better able to use either static or dynamic properties for grouping objects, and whether performance under these conditions would be better than when no property was given. One of the two study tasks, the free sort, also used by Rosch et al. (1976), asked…

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…

The role of language in conservation tasks and the development of the concept of conservation of quantity in young children are investigated in this study. A total of 50 children, aged 3.0 to 4.7 years, were divided into three groups according to age with a large number clustered around age 4.0 years. Children were randomly assigned to one of two…

Comprehension of reversible active and passive sentences was studied with 48 Japanese children between the ages of two and six. Four types of sentences were constructed using passive and active structures and two word orders: subject-object-verb (SOV) and object-subject-verb (OSV). The basic order of elements in a simple sentence in Japanese is…

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…

To produce and evaluate a language development program for culturally deprived preschool children based on characteristics of Piaget's theory of intelligence, a 6-week experimental study was carried out in Project Headstart, Starkville, Mississippi. Randomly-selected, 45 Negro Headstart enrollees made up three groups--two were taught the…

The acquisition of rules for formulating causative verbs was studied with children over a period of a few years. Most of the data is based on the spontaneous speech of the author's two daughters, from age 2;6 to 6;2 and from age 2;4 to 3;11. It was hypothesized that there are at least two prerequisites for the child's formulation of a general rule…

In all of his published work, Jean Piaget never abandoned his original theoretical framework for the understanding of human development. This framework insists that intelligence is essentially a biological phenomenon; its development is best understood as the development of a sophisticated and highly successful adaptation device. This device…

This article hypothesizes that language repetition of young children (in the sense used by Kobashigawa and Snow) does not help language acquisition. The evidence comes from the results of a prior study in which no indication was found that mothers who repeat themselves a great deal have children who acquire language more quickly. However,…
