属性失忆现象及其机制的系统探讨

属性失忆（Attribute Amnesia）现象是由申请者与Wyble博士首次提出的。该现象显示，当被试没有预期（Expectation）要报告某一信息（如字母颜色）时，他们即使刚刚（几秒之前）已经注意并且使用该信息完成了任务，仍无法在意外记忆测验时将其（字母颜色）准确报告。申请者和其他研究者基于该现象进行了系列研究，取得了丰硕的成果。然而，针对该现象的普遍性、影响因素以及内在机制等方面仍有大量问题尚未明确，值得进一步探讨。本项目拟采用行为实验和脑电技术相结合的方法，利用申请者团队首创或改造（如属性失忆与注意引导结合、属性失忆与脑电结合）的实验范式，从上述三方面问题入手系统探讨这一新颖现象，以进一步揭示该现象的本质。研究成果对阐明工作记忆的选择性机制具有重要意义，且有助于丰富和完善现有工作记忆理论，并为认知科学相关领域的研究和应用提供参考。

Chen and Wyble recently reported an interesting phenomenon, namely Attribute Amnesia, which shows that participants fail to report an attended attribute of a stimulus(e.g., color of a letter) that they had just used for a task, provided that they had no expectation to do so. Although this phenomenon has been replicated and extended by series of follow-up studies, a lot of issues regarding this phenomenon remain unclear. The present project plans to further clarify this surprising phenomenon by focusing on the issues of generalization, impacting factors as well as the underlying mechanism of this phenomenon, by using a combination of behavioral and EEG techniques. This project will not only shed new light on the selective mechanism of working memory, but also will provide implications for the research and applications in related areas.
