An experimental study investigated the influence of informational dependence on information appropriation as a function of epistemic authority's styles. In a 2x2 design, university students were informed that acknowledging epistemic dependence was related either to academic success or to academic failure, and were exposed to controversial information from an epistemic authority that used either an authoritarian or a democratic style. The main dependent variable was the extent to which participants appropriated the controversial information. Firstly, the results showed that students were more inclined to admit that their own academic competence depended on the information delivered by the teachers when epistemic dependence was related to success rather than to failure. Secondly, the admittance of dependence had a different impact on information appropriation according to the authority's style. Admittance increased appropriation under a democratic style whereas it decreased appropriation under an authoritarian style. (Contains 1 table and 2 notes.)
