Maccoby and Jacklin (1974) suggested that males generally perform better than females in spatial problem solving. The major aim of this article is to demonstrate that such a difference in spatial ability acccording to sex is not determined innately by examining both biological and psycho-social factors. While there has been no decisive evidence that biological factors, such as genes and/or maturity speed except hormonal-level in a fetus stage, affect individual differences of spatial ability, there are some psycho-social factors which siginificantly correlate spatial problem solving performance. The possibility that the psycho-social factors, such as sex-typed personality traits, affect the process of learning and solving spatial tasks is discussed.
