Replication of Guttman’s Structure of Intelligence

Abstract

This chapter utilizes a facet-theory approach for a reanalysis of Rimoldi’s (1951) matrix of intercorrelations. Rimoldi’s original hypothesis had centered on the nature and existence of a central intellective factor. Rimoldi proposed that such an hypothesized central intellective factor (often called Spearman’s g) was more appropriately a second-order factor. He proposed to show that a first-order factor analysis of the matrix would yield no central factor, but rather a collection of factors representing individual mental abilities. He further proposed that a second-order factor analysis would yield a central intellective factor that could be considered a general factor of intelligence.
