The aim of the present study is to investigate thinking styles at the interface between personality traits and intelligence. A total of 266 students in Germany and Austria completed the Thinking Styles Inventory for German-Speaking Samples (TSI-GER), the NEO Five-Factor Inventory (NEO-FFI) and the Intelligence-Structure Test 2000 R (I-S-T 2000 R). Structural equation modelling was applied to investigate whether thinking styles mediate the relationship between personality traits and intelligence. The results indicate that styles do not work as an interface between personality and intelligence, which suggests that styles represent a "stand-alone" learning prerequisite.
