Abstract
The relationship between thinking styles and personality types is investigated within the contexts of Sternberg's theory of mental self-government and Holland's theory of personality types. A total of 600 university students from Hong Kong responded to the Thinking Styles Inventory (TSI) and the Short-version Self-directed Search (SVSDS) that was specially designed for the present study. A major finding of this study is that thinking styles and personality types overlap to a degree. A secondary finding is that the SVSDS is sufficiently reliable and valid for assessing Holland's personality types. Implications of both findings are discussed.
