This work was aimed at a search for EEG corellates of efficiency of nonverbal creative performance. Standardized Torrens technique which makes it possible to quantitatively assess creativity was used. The EEG records were performed before and during test performance, EEG parameters were compared to Torrens scores on three scales: flexibility, originality and efficiency. Absolute values of spatial synchronization, coherence and spectral power both in the baseline and during the performance were calculated. Changes in these parameters were traced during the transition from the state of quiet wakefulness to creative performance. The narrow-band analysis of coherence and spectral power allowed the number and orientation of processes associated with creativity scales to be assessed. The absence of substantial EEG changes during the test performance is indicative of the steady, nondynamical functional state of the brain.
这项研究旨在寻找非言语创造性表现效率的脑电图相关指标。采用了标准化的托伦斯技术，该技术能够对创造力进行定量评估。在测试进行前和进行过程中记录脑电图，将脑电图参数与托伦斯在灵活性、原创性和效率三个量表上的得分进行比较。计算了基线期和测试过程中空间同步、相干性和频谱功率的绝对值。追踪了从安静觉醒状态到创造性表现状态转变过程中这些参数的变化。对相干性和频谱功率的窄带分析能够评估与创造力量表相关的过程数量和方向。测试过程中脑电图没有显著变化表明大脑处于稳定的、非动态的功能状态。
