从广义上说,女性在20岁时左右脑之间的连接更多,而同龄的男性则是左、右脑各自内部的连接纤维更多。维尔马称:“女性大脑两个半球之间无论是从左至右、还是从右至左的连接都更好些。男性则是左、右脑各自内部的连接和后脑到前脑的连接更佳。”
That suggests women might be better wired for multitasking and analytical thought, which require coordination of activity in both hemispheres. Men, in turn, may be better wired for more-focused tasks that require attention to one thing a time. But the researchers cautioned such conclusions are speculative.
这就表明了女性可能在完成多重任务和分析思维方面更出色,而这需要左右脑之间的协作活动。反过来,男性可能在集中思维方面更为出色,这需要他们将注意力一次只放在一件事情上。但研究人员谨慎表示,这些结论都是推测性的,并非定论。
Experts also cautioned that subtle gender differences in connections can be thrown off by normal disparities in brain size between men and women and in the density of brain tissue. Other factors, such as whether one is left- or right-handed, also affect brain structure.
专家们还警告称,连接方面微小的性别差异会被当成男女大脑尺寸及脑组织密度方面的正常差异而被摒弃。其他一些因素,如一个人是不是左撇子或右撇子,也会影响大脑结构。
