11名受试者分别执行4项言语任务和4项空间任务，同时记录双侧颞顶叶脑电图。脑电综合不对称性（8-12 Hz）在言语任务和空间任务之间存在显著差异。受试者的左右综合幅度比的语言-负空间差异在-(r = 0.88)和-（平均r = 0.75）受试者之间都是可靠的。百分之一的时间测量没有显示出显著的任务效应，可靠性很差。对于综合振幅，8个任务的左/右比率的平均值在会话之间也非常一致。
Temporoparietal EEG was recorded bilaterally while 11 subjects performed 4 verbal and 4 spatial tasks on two occasions. Significant differences in integrated EEG asymmetry (8-12 Hz) were found between verbal and spatial tasks in both sessions. Subjects’ verbal-minus-spatial differences in the ratio of left to right integrated amplitude were reliable both between- (r =.88) and within-(mean r =.75) subjects. A percent time measure did not show significant task effects and had poor reliability. For integrated amplitude, the means of the left/right ratios of the 8 tasks were also very consistent between sessions.
