This new edition of one of the classic works of psychology highlights the achievements of this pioneer in the study of intelligence and child development. (SLD)

Studied a possible convergence in the structure of cognitive abilities as specified by classical psychometric theory and two neo-Piagetian theories of cognitive development by administering a large test battery to 120 children aged 7 to 10. Results support the integration of several theories of intelligence into a comprehensive system. (SLD)

Whether mental attentional capacity increases as a linear function of age during normal childhood development, as predicted by the neo-Piagetian developmental theory of J. Pascual-Leone (1970 and later), was studied with 215 children aged 5 to 12 years. Results provide only partial support for the Pascual-Leone theory. (SLD)

The analysis or modeling of Piagetian and psychometric measures of mental ability is discussed. An application of structural modeling procedures allowing the testing of hypotheses in this domain is presented. Such a model is illustrated through a study of numerical functional relations tasks with 77 elementary school students. (SLD)

Heim's AH4 Test of General Intelligence, Raven's Advanced Progressive Matrices, and two Piagetian formal operations tests (Shayer's Science Reasoning Tasks and Arlin's Test of Formal Reasoning) were administered to 459 15-year-olds attending Secondary three (grade nine) in Singapore. A hierarchical factor structure was found underlying all of…

In a study of operative thought in children, 104 children, aged 4 to 9, were tested 5 times with the same 25 Piagetian tasks. There were manifest indicators of synergy in the development of the various behaviors, but it was not possible to validate specific problems of behavior organization. (SLD)

This study investigates the nature and the factor structure of infant intelligence. The Bayley Mental Scale items were administered. According to the analysis, intelligence at any age is a set of separate mental abilities at each age, and there are a variety of paths through which mental development occurs. (JAZ)

The effects of early educational intervention on the attainment of the Piagetian cognitive stage of concrete operations by 86 socioeconomically disadvantaged children aged 5, 6, and 7 years were assessed. The Concept Assessment Kit-Conservation developed by M. L. Goldschmid and P. M. Bentler (1968) was used. (SLD)

Bad intelligence tests seem as inevitable as death and taxes. However, new theories of intelligence are resulting in some promising developments. Thirteen approaches to the measurement of intelligence are described, divided into the following categories: classical psychometric; developmental; culture-sensitive; cognitive; biological; and systems.…
