Previous studies found that playfulness/openness of personality trait correlatedpositively with extreme response style (ERS), the tendency to use frequently extreme alternatives of a rating scale for any specic item content. Tsujimoto (2003) suggested that one's interest in abstracts might mediate the both. In the present study we examined the dierences between art and university students in ERS to explored his suggestion. The results showd that there was no signicant dierences between the both groups on the mean of ERS scores.
