This study explored the latent structure of divergent thinking as a cognitive ability across gifted and non-gifted samples of students utilizing multiple-group analysis of mean and covariance structures (MG-MACS). Whereas Spearman's law of diminishing returns postulates lower g saturation of cognitive tests with increasing ability level and consequently, a lower correlation of cognitive abilities in more gifted samples, recent evidence from creativity research has shown that correlations of divergent thinking with intelligence are unaffected by ability level. In order to investigate this conflicting state of affairs with respect to divergent thinking, we utilized increasingly restrictive MG-MACS models that were capable of comparing latent variances, covariances, and means between gifted (IQ > 130) and non-gifted (IQ ≤ 130) groups of students. In a sample of 1070 German school students, we found that a MG-MACS model assuming partial strict measurement invariance with respect to the postulated factor model of verbal, figural, and numerical divergent thinking could not be rejected. Further, latent variances and covariances of latent divergent thinking factors did not significantly differ between groups, whereas the gifted group exhibited significantly higher latent means. Finally, implications of our results for future research on the latent structure of divergent thinking are discussed.

This article provides an introduction to the special issue "Intelligence, creativity and giftedness". Intelligence, creativity and giftedness are often studied separately. Journals and conferences are mainly focused on just one of these topics. However their joint examination presents interest in theoretical, social and practical respects. The articles of this special issue reflect the cooperation initiated by researchers from Germany, France and Russia. This cooperation lead to a number of conferences held in Moscow, Paris and Muenster with the large international participation. (PsycInfo Database Record (c) 2022 APA, all rights reserved)

The CFT 20-R is often used to assess fluid intelligence. Hence, it can also be utilized to assess giftedness. The present study is concerned with an investigation of psychometric properties of the test with respect to measurement invariance between students of normal and higher intelligence. Analyses were conducted both at the item and scale level. A sample of N = 1886 male and female students from the lower, middle, and higher track of the German education system were administered the short form of the CFT 20-R. Comparing students of normal (IQ < 120) and higher (IQ ≥ 120) intelligence, DIF analyses at the item level revealed that measurement invariance was largely observed with respect to item difficulties but not discrimination parameters. Partial strong measurement invariance was observed at the subtest level. The CFT 20-R is therefore well-suited for a first screening of intellectual giftedness.
