中文摘要: 时间信息加工与注意关系密切,但研究者忽略了对时间信息选择性注意加工的早期阶段进行研究。在预实验的基础上,将行为实验、事件相关电位技术、时频分析技术和功能性磁共振成像技术结合起来,探讨时间信息选择性注意的抑制加工、增益加工的神经机制,及其与非时间信息(客体特征、空间信息)选择性注意的关系。本项目是选择性注意领域的重要补充,有助于澄清选择性注意领域关于N1效应产生机制的争论;也是时间信息加工领域的重要扩展,为建立时间信息加工的认知模型提供丰富的认知神经科学方面的证据。

英文摘要: There is a close relationship between temporal information processing and attention, however, yet far less attention has been devoted to understanding the early stage of selective attentional processing of temporal information. On the basis of the preliminary experimental data, various methods and techniques will be employed, such as the behavior experiment, the event-related potentials, the time-frequency analysis and the functional magnetic resonance imaging, to investigate the neural mechanism of inhibition and gain in the selective attentional processing of temporal information and the relationship between selective attentional processing of temporal information and that of non-temporal information(such as feature, spatial information). The research project will be an important supplement in the selective attention, and help to identify the debate on generation mechanism of N1 effect in the selective attention. It also will be a major expansion in the temporal information processing, and provide neural evidence for the cognitive model of temporal information processing.
