This study recruited kindergarteners and first graders to investigate gender and grade differences in semantic and spatial processing of number magnitude. Results based on the Bayesian statistics showed that (1) there was extreme evidence in favour of grade differences in both semantic processing and spatial processing; (2) there were no gender differences in semantic processing; and (3) boys developed earlier than girls in spatial processing of numbers, especially for the more difficult task. These results are discussed in terms of gender differences in cognitive mechanisms underlying semantic and spatial processing of number magnitude.

数字语义和空间处理发展中的性别差异。

这项研究招募了幼儿园和一年级学生，以研究性别和年级在数量级语义和空间处理中的差异。基于贝叶斯统计的结果表明：（1）极端证据支持语义处理和空间处理中的等级差异；（2）语义加工中没有性别差异；（3）在数字的空间处理上，男孩比女孩早发展，尤其是在较困难的任务上。根据性别机制在数量级语义和空间处理基础上的认知机制中的性别差异讨论了这些结果。
