[Inductive reasoning and intelligence test performance--analysis of the manner of the effect of 2 thought training methods for children].

For his training programs of inductive reasoning Klauer postulates a transfer effect to inductive thinking as well as to (performance in tests of) intelligence. As evidence for these claims, however, he uses the same data. That means the same tests are used to prove enhancement of inductive thinking and to prove transfer to performance in tests of intelligence. Moreover, Klauer's claim to train inductive thinking is criticized since better performances in at least some of the tests he administers can result due to enhancements in the area of visual perception. Finally, we ask what kind of effects the programs result in: Are they mere coaching effects or do the programs result in better performance due to enhanced competencies? The empirical evidence suggest that positive effects on inductive thinking do not last as long as perceptual competencies that are necessarily fostered when visual material is presented to children.
