摘要:

社会性预期优势效应是指个体在预期条件下的信息加工能力显著优于非预期条件。探讨社会性预期优势效应的神经机制, 是心理学家和认知神经科学家关注的一项重要课题。社会性预期编码模型可以为预期静默效应(预期刺激引起的神经活动减弱)提供理论解释, 但该模型不能解释社会性预期刺激诱发的增强神经活动。因此, 研究1和研究2将考察无意识和意识社会性注意在社会性预期编码模型中的作用, 从而将它们整合到该模型中。研究3不再局限于对社会性预期编码模型的考察, 而是扩展到对预期转换机制的探讨, 最终将社会性预期编码模型和预期转换机制整合在预期节俭化框架之下。对于社会性预期优势效应神经机制的研究不仅能够完善社会性预期编码模型, 还有助于拓宽社会性预期研究的视角。

Abstract:

The superiority effect of social prediction is a well established phenomenon in social cognition literature, whereby predictable stimuli are better recognized than unpredictable stimuli. The neural mechanism for the superiority effect of social prediction is an important topic in the area of cognitive neuroscience and psychology. Predictive coding model suggests that predictable neural signals are attenuated. However, the predictive coding model has been challenged by the fact that prediction sometimes seems to enhance rather than reduce neural signals. Therefore, study 1 and 2 will investigate the role of unconscious and conscious social attention in the predictive coding model, thereby embedding them in the model. In study 3, we will explore a translation mechanism, and ultimately construct a predictive parsimony frame which consisted of the translation mechanism and the predictive coding model. Exploring the neural mechanism for the superiority effect of social prediction may contribute to improving the predictive coding model and broadening the research field of social prediction.
