有意识与无意识视觉注意的时空机制比较

由于意识容量的限制，很多视觉信息无需依赖我们的意识就可以被加工和处理。以往零星的研究表明，无意识加工后的信息可以改变注意资源的分配，称之为无意识注意。但是关于无意识注意这一重要现象，我们目前还没有一个有效的解释框架，缺乏对其基本时间空间机制的了解，而且以往不少研究可能存在混杂因素而导致结果不好解释，因此无意识注意的进展亟需严谨和系统的研究。借助我们以往在无意识加工的理论积累，方法积累和在无意识注意的前期研究基础，本项目致力于在方法上完善对意识水平的测量与操纵，通过从低水平神经层面的分析角度（如gamma震荡）到更高水平的认知层面的视野（如空间变换和学习机制）比较有意识与无意识的视觉注意，从而系统地描绘无意识注意的基本时空机制，为下一步的理论和计算模型研究作重要铺垫，也为以后在临床和应用研究中采用相应的实验方法探索新的测量方法甚至是治愈手段提供严谨的方法和理论支持。

Our conscious processing system is very limited in its capacity, necessitating unconscious processing of certain information. But can unconsciously processed information guide visual attention, and how does it do so? Currently, not only do we lack an explanatory framework to tackle this issue, but some existing research may suffer from confounds and artifacts. Moreover, other than some disparate research, we lack systematic efforts on this issue. Building on our prior work on unconscious processing, including theoretical (“unconscious binding hypothesis”), methodological (“priming of awareness”), and other empirical research (e.g., spatial-temporal adaptation in conscious and unconscious attention), this project aims to use rigorous awareness manipulation and measurement, and compare the spatiotemporal mechanisms of conscious and unconscious visual attention, ranging from low-level neuronal perspectives (such as gamma synchronization) to higher-level cognitive perspectives (such as spatial transformation and learning mechanisms). Through this systematic approach, this project is well posited to provide much needed empirical basis for future theoretical and computational modelling research on unconscious attention, as well as offer methodological and theoretical basis for future clinical and applied research in exploring experimental measurement and even therapeutical tools.
