情绪体验影响估算策略运用的认知与脑机制

Subjects: Psychology >> Experimental Psychology

揭示情绪体验影响个体完成各种认知任务的认知神经机制是研究者关注的热点问题。以往研究主要采用问卷法和行为实验,集中考察了焦虑对估算策略运用的影响,但这种影响潜在的脑机制尚不清楚,对焦虑以外的情绪体验与估算策略运用之间关系的研究也极其缺乏,而情绪调节对估算策略运用影响方面的研究基本处于空白。本研究将采用面孔表情图片作为情绪刺激材料,结合事件相关电位(event related potential, ERP)技术,采用启动范式,尝试从外显和内隐两个角度,考察不同效价的情绪体验在估算策略运用过程中所起的作用,进而揭示情绪调节影响估算策略执行的时间动态特征和大脑激活模式。这将有助于充分认识情绪体验影响估算策略运用的认知与脑机制,为更好的优化估算策略运用效果提供实证依据。

On dark matter

Subjects: Physics >> The Physics of Elementary Particles and Fields

In this article, I shall propose an enlightening view on the origin of dark matter abundance, in which I introduce a neutral primordial field, which is a new field beyond the standard model, the mass of the primordial field is confined in the vicinity of neutrino mass (or 1-2 orders of magnitude different from the neutrino mass). All the standard model elementary particles are produced spontaneously from this field in the Big Bang epoch of the universe and then these produced elementary particles decayed or annihilated in the well-known standard model interactions. The relic of the primordial field appears in a form of vacuum energy can not only give naturally the correct abundance of dark matter in the present universe, but provide a natural solution to the cosmological constant problem as well. We find that the conventional methods of detecting dark matter either fail or have great difficulties to detect the remaining vacuum energy of the primordial field, and how to confirm the existence of the remaining energy of the universe's original energy in experiment is still an open problem.
