在心理学试验中,受试者进行4种不同难度的心算,并记录他们的脑电图,本文计算了23名受试者在4个不同难度下心算时的信息传输序列以及这些序列的C1C2复杂性和L em pe l-Z iv复杂性,在观察由复杂性构成的信息传输矩阵时,发现有20名受试者在进行难度最大的心算时,在由信息传输矩阵转化成的图像中出现了非常明显的“十字架”,表明十字架出现位置所对应的导联和其它导联之间的信息传输复杂性较高,而所有的受试者在进行另外三个难度水平的心算过程中并未出现“十字架”。提示在计算复杂性过程中,C1复杂性比另外两个复杂性计算方法效果好。 In psychological tests, subjects performed four different levels of mental arithmetic and recorded their EEG. In this paper, we calculated the information transfer sequence of 23 subjects under different mental arithmetic and the C1C2 Complexity and Lectra lZ complexity, observing information transfer matrices consisting of complexity, 20 subjects were found in the images transformed by the information transfer matrix in the most difficult mental arithmetic The very obvious “cross,” indicating that the crosses appear more complex in terms of information transfer between leads and other leads, while all subjects did not appear in the mental arithmetic process at three other difficulty levels “cross”. Tip C1 complexity is more effective than the other two complexity calculation methods in calculating complexity.
