This study was designed to achieve two objectives. The 1st was to investigate the cross-cultural validity of the Thinking Styles Inventory (TSI; R. J. Sternberg & R. K. Wagner, 1992), which is based on the theory of mental self-government (R. J. Sternberg, 1988, 1990, 1997). The 2nd was to examine the relationships between thinking styles as assessed by the TSI and a number of student characteristics, including age, gender, college class level, work experience, and travel experience. One hundred fifty-one students from the University of Hong Kong participated in the study. Results indicated that the thinking styles evaluated by the TSI could be identified among the participants. Moreover, there were significant relationships between certain thinking styles, especially creativity-relevant styles and 3 student characteristics: age, work experience, and travel experience. Implications of these findings for teaching and learning in and outside the classroom are discussed.
