Abstract

The interindividually varying tendency to change and optimize behavioral patterns spontaneously is called ''behavioral flexibility''. Whereas our former work concentrated on development and validation of corresponding objective tests similar to procedures used by Wertheimer and Luchins, the topic here is the question of which individual cognitive resources are advantageous for flexible behavior. Behavioral flexibility is hypothetically linked with Baddeley's concept of the central executive in working memory, whose capacity varying among subjects is assumed to be an underlying factor. The central executive is assumed to be responsible for the control and integration of information from different sources; consequently it should initiate the change between strategies in spontaneous optimization too. Baddeley's random production task was applied in two experiments as a differential measure of the capacity of the central executive in working memory. Subjects are instructed to produce a random sequence of two hundred figures (1-9, respectively, one figure per second). This task requires capacity of the central executive in working memory, because the whole time course one hasto resist automatization of stereotyped sequences, i.e., to prevent the formation of routines. The results of two studies show that flexible persons perform better in producing random orders of numbers compared to less flexible persons. It is concluded that in working memory a high capacity of the central executive is of particular impact for flexible behavior.
