Gender differences in EEG patterns associated with verbal creativity were studied by EEG mapping. The EEGs of 18 males and 21 females (right-handed university students) were recorded during a performance of Remote Associates Task (RAT) compared with the letter-fluency and simple associate's tasks. Gender differences were found in a factor structure of the indices of verbal thinking and a score of generating words was greater in women than men. No significant gender differences in originality of associations were revealed, however, gender-related differences in the EEG-patterns were found at the final and initial stages of RAT. In men, the beta2-power was increased in both hemispheres at the beginning of test. To the end of testing, the power of oscillations in the beta2 band increased only in the central part of the cortex. In women, the beta2-power was increased to a greater extent in the right than in the left hemisphere at the initial stage of task performance, whereas the final stage was characterized by a relative decrease in beta-activity in parietotemporal cortical regions and increase in the left prefrontal region. It is suggested that the verbal creative thinking in men is based mostly on "insight" strategy whereas women additionally involve the "intellectual" strategy.
通过脑电图描记术研究了与言语创造力相关的脑电图模式中的性别差异。在执行远程联想任务（RAT）期间，记录了18名男性和21名女性（右利手大学生）的脑电图，并与字母流畅性任务和简单联想任务进行比较。在言语思维指标的因素结构中发现了性别差异，女性生成单词的得分高于男性。然而，在联想的原创性方面未发现显著的性别差异，不过在RAT的最后阶段和初始阶段发现了与性别相关的脑电图模式差异。在男性中，测试开始时两个半球的β2功率均增加。到测试结束时，β2频段的振荡功率仅在皮质中央部分增加。在女性中，任务执行初始阶段右侧半球的β2功率比左侧半球增加得更多，而最后阶段的特征是颞顶叶皮质区域的β活动相对减少，左侧前额叶区域的β活动增加。研究表明，男性的言语创造性思维主要基于“顿悟”策略，而女性还涉及“智力”策略。
