Although creativity techniques are highly recommended in working environments, their effects have been scarcely investigated. Two cognitive processes are often considered to foster creative potential and are, therefore, taken as a basis for creativity techniques: knowledge activation and conceptual combination. In this study, both processes were enhanced individually and jointly with an appropriate technique. Knowledge activation was fostered by the mind-map technique and conceptual combination by the random-input technique. The "random-map technique" evolved from merging these two techniques together. The two different techniques were tested in a 2 × 2 factorial experimental design with 80 participants. It was assumed that (a) both individual techniques would enhance creative potential when compared to the control group, and (b) the combined technique would lead to more creative potential than implementing the techniques individually. Results showed an increased creativity level of each of the individual techniques when compared to the control group. The combined creativity technique resulted in even higher creativity level when compared to both individual techniques. Thus, fostering different creativity processes jointly had an additive effect on creative potential.
