Personality and academic attainment: a cross-cultural study.

Summary. This study examines the ‘age effect’ hypothesis from British and American studies, that academic success at primary school is linked to stable extraversion while success at university is associated with introversion, with black and white school children (age 14) and black and white university students (age 20), brought up in non-Western and Western cultures, respectively. The extraversion and neuroticism scores of the subjects on the JEPI or the EPI were compared to their academic success, given by their performance in school or university examinations. The results supported the ‘age effect’ hypothesis in both white and black groups.
