英文摘要	It has been proposed that temporal perception is implemented in a "time window'' of approximately 3 s which we experience as "present''. Using mismatch negativity (MMN), we tested the hypothesis whether a time window of 3 s is selective for pre-attentively detecting the violation of regularity in a stimulus sequence by employing different interstimulus intervals. Our results showed that in frontal midline areas, the amplitudes of MMN were significantly larger for the shorter interstimulus intervals up to 3 s than for the longer ones. In lateralized frontal areas, male subjects seemed to have a stronger effect in the temporal modulation of the MMN, which might deserve further investigation. We conclude that a time window of 3 s is selective for neuronal mechanisms to process deviant stimuli and that information processing is temporally segmented, creating a "subjective present'' in discrete sequential steps.; CPCI-SSH(ISSHP); SSCI; ,SI; S131-S135; 16
