Four bipolar temperament qualities (i.e. extroversion-introversion, practical-imaginative, thinking-feeling and organized flexible) of 800 South African children, ages 9-10, 11-12, 13-14 and 15-17, first are described and then compared to temperament qualities of 800 US children of the same ages. South African children do not differ in their preferences for extroversion-introversion and more frequently prefer practical to imaginative, feeling to thinking and organized to flexible styles.
