The present study investigates the relationship between openness to experience and its subscales as a factor of personality with the two kinds of fluid and crystallized intelligence in students. The purpose of this study is to determine amount of the relationship between personality and two dimensions of fluid and crystallized intelligence. To do this, by using research method of correlation, 115 female students at university of Tehran were randomly selected and administered the openness to experience subscale of Costa & McCrae personality inventory (NEOPI-R) and Jackson multidimensional aptitude battery (MAB). Using Pearson correlation and multivariate regression of stepwise results showed both fluid and crystallized intelligence positively and significantly correlated with the openness to experience of total and fantasy. Also, significant positive relationship between fluid intelligence, and actions and ideas were observed. Furthermore, crystallized intelligence was significantly and positively correlated with feelings and ideas. Moreover, the openness to experience of total anticipated fluid intelligence variances and only fantasy and ideas of the openness to experience dimensions anticipated crystallized intelligence. The results indicated that personality trait of the openness to experience play an important role in the development of fluid and crystallized intelligence.
