The purpose of this study was to assess content and concurrent validity of the Torrance Tests of Creative Thinking (TTCT). The subjects were thirty-four art majors at North Texas State University between the ages of nineteen and thirty-nine. Content validity for the TTCT, as assessed by seven judges (art professors), was very high; concurrent validity was very low. Only one judge's ranking of the criterion was significantly intercorrelated with that of the other judges (p<.05). There were no significant rho correlations between the TTCT and the criterion (p<.05). The t-ratio differences between the males and females, for all tasks of the TTCT, were non-significant (p<.05). It was concluded that the TTCT were not appropriate for use with adult art majors.

This diploma thesis examines the impact of playing RPG on the development of players'creative thinking. Our aim was to analyze the development of creative thinking in relation with RPG playing. This development was observed in the group of beginners and advanced players and in the control group during six months using creative thinking tests (Torrance Tests of Creative Thinking - Figural, Urban's Test for Creative Thinking- Drawing Production). Tests were administered three times, in the beginning, after 3 months and after 6 months. During the second measurement the experimental group was also assigned a Creative Personality Scale (CPS). The obtained values were processed using descriptive statistics, correlation analysis and t-tests. Overall, it has not been conclusively proved that playing RPG influenced the creative thinking development of players, but a certain trend of improved creativity, especially in RPG-beginners was observed. We found out that the gaming intensity (hours per week) and the creativity are not related. A positive relation between the CPS score and the creativity improvement and also relation between the age and the creativity improvement was established.
