时间信息自动加工与控制加工的电生理学指标

The Electrophysiological Index for the Automatic and Control Processing of Temporal Information

人类时间信息加工的统一机制问题一直备受研究者关注。新近研究表明失匹配负波(MMN)是与时间信息自动加工有关的ERP成分,关联负变化(CNV)是与控制加工有关的ERP成分,而刺激遗漏电位(OSPs)既与自动加工又与控制加工有关。以三种ERP成分为指标的研究均为时间信息自动加工和控制加工的存在提供了可能的依据。未来研究不应该纠缠于自动加工和控制加工分界点的探究,而是着重从时间全程视角考察时距加工机制的特点。

Recently, there are more concerns about the issue of the unit mechanism of human temporal information processing. Recent studies showed that the Mismatch Negative wave （MMN） was related with automatic processing, while Contingent Negativity Variation （CNV） related with control processing, and omitted stimulus potentials （OSPs） corresponded with both automatic and control processing. Studies about all of the three ERPs proved the existence of both processing. Further studies should pay more attention on exploring the duration processing mechanism rather than on the segmentation point of automatic and control processing.
