Although the research of interaction of aggression and creativity dates back to the beginning of the early 1900, the possibility of creativity tests to use to examine aggression is novel. In the present study (as a pre-study of long-term research which aimed to create and validate an aggression index) we focus on frequency and correlations of aggressive responses which manifest in creativity tests. Methods. We analyze the differences and correlations of a number of aggressive responses which were given to stimuli the Unusual Uses and the Circle test (verbal and nonverbal creativity tests; N = 356 people). According to our results, the numbers of aggressive responses to the different stimuli of creativity tests: a)  are significantly different (p<0,001), b) do not correlate with each other widely (max r=0,414), c) depend on sample-variables of gender and age. In the case of creativity tests, we think it is possible to elaborate on a special aggression index, but during this work, we have to consider the results of this study.
