Abstract:

Personality has an important influence on cognitive ability. The relations between different personality traits and cognitive ability are distinct, and there are age differences in their relations. Current research is mainly about three aspects: the relations between personality traits and cognitive ability; the impact of different personality traits on cognitive ability; the comparison of the relations in different ages. The results of the impact of different personality traits on cognitive ability become clear, but there still is lots of controversy in current research. In order to get more scientific conclusion of the research problem, the future research can be further deepened in the following aspects: the stability of personality and the influence on cognitive ability; the mechanisms of the impact of personality on cognitive ability and the influencing factors; cross-cultural research; research paradigm.

Key words: personality traits, cognitive ability, relations, age differences
