[Cognitive training and strategy behavior: comparative evaluation of 2 cognitive training programs].

Combining a non-comparative with a comparative evaluation, two modern programs for fostering inductive reasoning, namely the German version of the "Cognitive training for children" by Klauer and Phye (1994; Klauer 1989), and the "DenkMit" by Sydow and Meincke (1994), are compared to each other and to a control program which intends to enhance aspects of memory instead of inductive reasoning. The programs were performed with N = 49 children between six and eight years who had been postponed from regular school because of various reasons or who had been selected as especially in need for particular interventions from first classes. Besides the psychometric test often used for assessing inductive reasoning, i.e. three subtests of the German form of the Culture Fair Test by Cattell (Weiss a. Osterland 1980), tasks of concept formation were applied for assessing changes in strategic behavior of children--a type of task which has been used in connection with inductive reasoning since many years. Counter to expectations, the children whose memory was trained, showed changes in performance in the psychometric test in a similar size as the children whose inductive reasoning was trained. These effects are interpreted in terms of special attention directed to the children during the intervention situation. Moreover, it was found that despite the authors claim to the opposite the DenkMit did not cause any changes in visual perception. In contrast to the author's intentions, the "Cognitive Training for Children" did cause some substantive changes in the area of visual perception. The pattern of results with the concept formation tasks, however, overall indicates that the reasoning programs caused some changes in strategic behaviors of the children. Although these changes are not very impressive, they cannot be attributed to extraneous factors such as special attention.
