358 female and 203 male college students compared themselves to others of the same gender and age on 10 everyday spatial abilities, also indicating for each ability the time spent per week in practice. Men's higher ratings for eight abilities were accompanied by greater practice on four. This finding, given equally strong correlations within each sex between rated ability and practice, lends more support to a hypothesis of differential practice between the sexes than differential self-esteem to account for sex differences in spatial performance.
358名女大学生和203名男大学生就10项日常空间能力与同性及同龄的其他人进行了比较，同时还指出了每项能力每周的练习时间。男性在八项能力上的较高评分伴随着四项能力上更多的练习。鉴于在每种性别中，评分能力与练习之间的相关性同样很强，这一发现为性别差异练习的假设提供了更多支持，而非不同自尊来解释空间表现中的性别差异。
