This meta-analysis reviews 79 studies (N = 46,605) that examined the existence of gender difference on intelligence in school-aged children. To do so, we limited the literature search to works that assessed the construct of intelligence through the Wechsler Intelligence Scales for Children (WISC) batteries, evaluating eventual gender differences in indices and subtests. The theoretical framework we adopted is the cross-battery approach which locates cognitive abilities into different levels, also considering the possible mediating effect of the version of the WISC being used. As for broad abilities, a notable discrepancy emerged in favour of males for visual and crystallized intelligence, while female/male differences on fluid intelligence were negligible. Conversely, females’ performance on the processing speed factor was superior. Interesting results emerged at the subtest levels, albeit with less pronounced differences in performance. Results generally showed that older versions of WISC batteries displayed larger gender differences compared to the most recent ones.

这项荟萃分析回顾了 79 项研究（N = 46,605) 研究了学龄儿童智力的性别差异的存在。为此，我们将文献搜索限制在通过韦氏儿童智力量表 (WISC) 电池评估智力结构的作品，评估指数和子测试中的最终性别差异。我们采用的理论框架是跨电池方法，将认知能力定位到不同的水平，同时考虑到所使用的 WISC 版本可能的中介效应。至于广泛的能力，男性在视觉和结晶智力方面出现了显着差异，而女性/男性在流体智力方面的差异可以忽略不计。相反，女性在处理速度因素上的表现更为出色。有趣的结果出现在子测试级别，尽管性能上的差异不太明显。结果普遍表明，与最新版本相比，旧版本的 WISC 电池显示出更大的性别差异。
