EEG activity of 16 adult volunteers. 8 male and 8 females was monopolarly recorded at P3 and P4 at rest and during solution of three series of tasks: one analytic, one spatial and one mixed demanding both kinds of processing. The following main effects were observed: Men showed significantly higher beta relative power than women, while women showed significantly higher alpha relative power than men during all conditions. Alpha relative power decreased, while theta relative power increased during tasks solution in both sexes. Beta relative power was significantly higher at the left parietal only in men. Interparietal correlation was significantly higher in women than in men during all conditions and bands. For the theta band it increased from baseline values during tasks solution in men, while in women it decreased during the analytic task.
对16名成年志愿者（8名男性和8名女性）的脑电图活动进行了单极记录，记录部位为静息状态及完成三组任务时的P3和P4。这三组任务分别是：一组分析性任务、一组空间性任务和一组同时需要两种处理方式的混合性任务。观察到以下主要效应：在所有情况下，男性的β相对功率显著高于女性，而女性的α相对功率显著高于男性。在完成任务过程中，两性的α相对功率均下降，而θ相对功率均上升。仅在男性中，左侧顶叶的β相对功率显著更高。在所有情况和频段下，女性的顶叶间相关性显著高于男性。对于θ频段，男性在完成任务过程中其相关性从基线值上升，而女性在分析性任务过程中其相关性下降。
