Features of EEG pattern during verbal creative thinking depending on experimental instruction were studied in men and women. Spectral power density was analyzed in six frequency bands (4-30 Hz). Performance of a creative task produced an increase in the power of theta (4-6 Hz) and beta2 (20-40 Hz) components and decrease in the power of alpha (8-13 Hz) and betal (13-20 Hz). Changes in the alpha and betal bands were observed, predominantly, in the posterior areas, whereas power of the thetal and beta2 bands increased in the anterior areas. Independently of instruction, women demonstrated greater synchronization in the theta1 band than men, whereas in men the desynchronization in the alpha2 band (10-13 Hz) was more pronounced. When the subjects were instructed to create original sentences, a widespread decrease in the EEG power was observed in the band of 8-30 Hz as compared to instruction "to create sentences". Thus, the instruction-related changes in EEG power were not gender-specific. They may reflect neural activity mediating selective attention.
根据实验指导,研究了男性和女性在言语创造性思维过程中脑电图模式的特征。分析了六个频段(4 - 30赫兹)的频谱功率密度。创造性任务的执行使θ波(4 - 6赫兹)和β2波(20 - 40赫兹)成分的功率增加,α波(8 - 13赫兹)和β1波(13 - 20赫兹)的功率降低。α波和β1波的变化主要出现在后部区域,而θ波和β2波的功率在前部区域增加。与指导无关,女性在θ1频段的同步性比男性更强,而男性在α2频段(10 - 13赫兹)的去同步性更明显。当受试者被要求创作原创句子时,与“创作句子”的指导相比,在8 - 30赫兹频段观察到脑电图功率普遍下降。因此,与指导相关的脑电图功率变化并非性别特异性。它们可能反映了介导选择性注意的神经活动。
