EEG was recorded from left and right temporal areas while subjects learnt high- and low-imagery words. Asymmetry in power in the alpha band, in the form of less power from the left hemisphere, was observed only during the learning of high-imagery words. This condition also gave rise bilaterally to more theta power. The difference between conditions in levels of inter-hemispheric coherence predicted, in both frequency bands, relative levels of recall of the two word types. It is suggested that the alpha and theta bands of the EEG may reflect different aspects of information processing in these tasks.
在受试者学习高意象词和低意象词时，从左右颞叶区域记录脑电图。仅在学习高意象词时观察到阿尔法波段功率的不对称，表现为左半球功率较低。这种情况还双侧产生了更多的θ波功率。在两个频段中，半球间连贯性水平的条件差异预测了两种词类型的相对回忆水平。有人提出，脑电图的阿尔法和θ波段可能反映了这些任务中信息处理的不同方面。
