Recently, it has been shown that feature discrimination in temporally regular rhythms results in enhanced performance compared with feature discrimination in temporally irregular rhythms. In this study, we investigated the influence of temporal predictability on attentional processing. We show that temporal predictability of a sequence results in a decreased peak latency of the P3b compared with temporally random sequences. The present findings clearly illustrate that temporal predictability results in faster processing of deviant stimuli.
最近的研究表明，与在时间上不规则的节奏中进行特征辨别相比，在时间上规则的节奏中进行特征辨别能提高表现。在本研究中，我们调查了时间可预测性对注意力加工的影响。我们发现，与时间上随机的序列相比，序列的时间可预测性会导致P3b的峰值潜伏期缩短。目前的研究结果清楚地表明，时间可预测性会导致对偏差刺激的加工更快。
