The central auditory system for event perception involves the integrating mechanism of sequential information addressed by the present study. The mismatch negativity (MMN) component of the event-related potentials (ERP) reflects the automatic detection of sound change. ERPs to occasionally omitted stimuli were measured when sequences with constant stimulus onset asynchronies (SOAs) were presented. In separate blocks, the SOA was from 100 to 350 ms. A clear MMN was elicited by a stimulus omission in a sequence of regularly spaced tone pips only when the SOA was shorter than 150 ms, yielding an estimate for the duration of the temporal window of integration used the perceptual segregation of auditory events.
用于事件感知的中枢听觉系统涉及本研究中所探讨的序列信息整合机制。事件相关电位（ERP）的失匹配负波（MMN）成分反映了对声音变化的自动检测。当呈现具有恒定刺激起始间隔（SOA）的序列时，测量对偶尔遗漏刺激的ERP。在不同的组块中，SOA为100至350毫秒。仅当SOA短于150毫秒时，在有规律间隔的音调序列中，刺激遗漏才会引发明显的MMN，这为用于听觉事件感知分离的整合时间窗口的持续时间提供了一个估计。
