Suggests that there exists a "finite" number of elementary concepts and distinguishable modes of thinking, that all human beings tend to acquire the same set of elements of thinking and the same strategies with which to understand and control their physical environment, and that the method of analysis used here is a standard scientific method.…

Article considered experiments that tested the contentions of Piaget and Peel who believed that formal thinking is not established before 11-12 years of age. These studies were tied to the success achieved by pre-adolescent children in solving verbal three-term series problems. (Author/RK)

From a factor analysis of 33 variables on 83 first-grade children an animism factor, involving children's conceptions of life, was identified. Animism was found to be relatively independent of operational thought, Piagetian-type problem solving, and the ability to give causal explanations of physical phenomena. (Author)

Hypothesis that non-conservers would give more perceptual than identity arguments, and that conservers would give more identity than perceptual reasons for their judgments was supported by the conservation pretest results. (Authors)

These results support Piaget's position that preoperational children respond to the perceptual lack of equality but not to the lack of conceptual equivalence in class-inclusion problems. (Authors)

Study attempted to specify two complementary aspects of children's inferential size judgments within the context of Piaget's theory. (Authors)

This study uses Lansdown's approach to Vygotsky's theory of language and concept development as the basis for comparing the conceptual level Ghanaian children express in their native languages (Ga or Twi) and in their school language (English). (Editor)

This study reports the development of a sentence preference test designed to contrast tendencies to abstract, generalise and particularise in thinking. (Editor)

The construct of conservation, as presently studied in dichotomous form (i.e., Conservers vs. Nonconservers), may be a convenient fiction, but that is all it is. There seems to be great need to treat this dimension as the continuous variable it really is. (Authors)

Purpose of the study is to test Piaget's hypothesis of a parallel relationship between moral concepts and logical structures in human development. (Author)

This study was undertaken to test the validity of Neuringer and Lettieri's hypothesis (suicide as a result of a life style versus suicide as an acute reaction to problem situations) about the relationship between suicidal behavior, state and cognitive style. (Author/RK)

Research studies were conducted to determine the effectiveness of multisensory learning systems in teaching basic concepts to two and five-year-old children. (Author/RK)

Performance demonstrated that the conceptual style and cognitive tempo of the model changed the styles and tempos of the Ss and that these effects generalized to independent tasks. (Author)

The present investigation was addressed to the hypothesis that cultural differences in home background are an important influence in the development of children's understanding of the purpose of writing and their concepts of the language units employed in the written code. (Editor)
