The current status of the studies on cultural values usually focuses on the diversity of national characteristics. One of the newly emerging topics on the agenda is the cultural intelligence and its possible impacts on the integration of different cultural environments. So this new agenda and its uncovered aspects motivate us to conduct such a research. Within this frame, we examined the hypotheses related to the effect of four dimensions of culture on four dimensions of cultural intelligence. We find that the value of individualism/collectivism, among the dimensions of culture, causes a differentiation on the values of metacognitive intelligence, cognitive intelligence and motivational intelligence but not on behavioural cultural intelligence. The value of power distance cause a change on all dimensions of cultural intelligence except for the metacognitive intelligence, while the value of uncertainty avoidance cause a change on all dimensions of cultural intelligence except for the cognitive intelligence. On the other hand, the Femininity/Masculinity dimension of culture has an impact only on cognitive intelligence. The results of the research may have contributions both to the academics and practitioners of intelligence and culture areas. Keywords: cultural intelligence; metacognitive intelligence; cognitive intelligence; motivational intelligence; behavioural intelligence; national culture.
