Construct validity in intelligence test construction can be attained by the use of Piaget-type tasks, which involve the basic categories of intellectual functioning''; examples are given. (Author/SP)

The question of how to integrate developmental (Piagetian) and psychometric conceptions and assessments of intelligence is considered. A solution which incorporates the contributions of each position--intelligence as forms and as traits--is offered. Premises and objectives of each tradition are reviewed and compared. Overlaps make synthesis…

Examined quantitative evidence of an intellectual growth spurt during early adolescence by combining modern psychometric modeling, computerized testing with the Raven progressive matrices, and longitudinal socioeconomic and educational backgrounds. Found that gender difference was not significant. Notes the impact of this evidence on educational…

Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…

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.…
