| 摘 要： | 本实验利用双侧视野的追随程序，把外显测验和内隐测验技术结合起来，对注意的选择性进行研究。实验结果显示。在低信息负荷和中信息负荷的时候，对追随视野的追踪没有抑制对非追随视野的认知加工，两侧视野中进行高级认知加工的信息没有显著差别，这符合反应选择的观点；在信息负荷较高而发生超载的时候，对追随视野的追踪抑制了对非追随视野的认知加工，两侧视野中进行高级认知加工的信息达到显著差别，这符合知觉选择的观点。有关知觉选择和反应选择的争论，在不同信息负荷水平这个框架内得到了有效地解决。

| Abstract: | This experiment used a tracking procedure of bilateral visual fields,and combined explicit measurement with implicit measurement to study selective attention.This research indicated that high-level cognitive processing of non-tracking visual field could not be prevented(late selection)when the information load as low,and that some information was filtered(early selection)before high-level cognitive processing when information was overloaded.These findings provided a resolution to the long-standing debate over early and late selections in a framework of different information load levels. |
