The dynamic coherence analysis based on multivariate autoregressive modeling was applied in the observation of synchronization between brain areas during cognitive processing.The result indicates that the synchronization of relative brain areas happens automatically despite the distractive stimulus during object perceiving,but the disturbed attention affects the synchronization of those areas involved in the judgement and voluntary movement as the way it affects the reaction time.

基于多变量自回归模型的动态相干性分析方法，被用于观察不同脑区在认知过程中的同步化，结果显示，人在感知和识别物体时，相关的脑区自动地发生了同步化的神经活动，这种同步化被证实是不受干扰刺激影响的，但被干扰的注意力确实影响了与判断和主动运动有关的脑区的同步化，而且这种影响的趋势与反应时间的分析结果一致。
