无意识信息引发的认知控制及其神经机制

对无意识信息引发的认知控制的研究是揭示意识的功能与局限的重要方法和步骤.在无意识认知控制研究中主要采用模式掩蔽和偏对比掩蔽创设无意识条件,使用客观测量方法对意识状态进行测量.作者从无意识抑制控制、无意识冲突控制和无意识错误加工三个方面回顾了近年对无意识认知控制及其神经机制的研究.已有研究从行为和认知神经研究两个方面强有力地证明了无意识认知控制的存在,揭示了其神经机制.这些研究拓展了人们对意识信息广度和深度的认识,也为未来进一步揭示意识的起源等问题奠定了一定的基础.未来的研究可以从无意识认知控制和有意识认知控制的相互转化等方面进行进一步研究.

Cognitive Control Triggered by Unconscious Information and Its Neutral Mechanism

Studies on cognitive control triggered by unconscious information provide important methods and procedures to reveal the function and limitation of consciousness. Unconscious cognitive control studies mainly adopt pattern masking and meta-contrast masking to create unconscious condition and measure consciousness by objective means. This paper reviews recent studies on unconscious cognitive control and its neural mechanism from unconscious inhibition control, unconscious conflict control and unconscious error processing. Both behavioral and cognitive neuroscience studies have evidenced the existence of unconscious cognitive control and revealed its neural mechanism. These studies expand our understanding of conscious information and lay the foundation for future revelation of conscious origin. Future directions that researches can be done on transition between unconscious cognitive control and conscious cognitive control are also discussed.
