自我情绪一致性效应及其可逆性:探究负荷理论

The Self-emotion Consistence Effect and Its Reversibility: Investigation on Load Theories

认知资源系统是单一的,还是多重的?根据不同脑区调节自我积极、消极信息加工这一脑成像研究结果,本研究通过验证自我情绪一致性效应(自我积极、消极工作记忆负荷干扰同类认知任务,而不干扰不同类认知任务)及其可逆性,考察这一争议。两个实验采用改编的阅读广度范式,通过操纵工作记忆负荷类型,证实了该效应的存在;通过控制认知任务的加工速度,发现了该效应的可逆性。研究结果支持了多重资源的观点。

One of the major questions asked about resources is whether there is a central, unitary pool of resources or there are multiple pools of resources. This question is a crucial issue and a long-term debate in Psychology. Based on the findings that the self positive information processing and the self negative information processing are in- volved in different brain areas, this series of research adopted a revised version of reading span paradigm to inves- tigate whether there exists the self-emotional consistence effect, and whether this effect is reversible. The self-emo- tional consistence effect can be defined as the phenomenon that self-emotional （positive and negative） working memory load interferes with the same kind of self-emotional （positive and negative） information processing, but don not interfere with the different kind of self-emotional （positive and negative） information processing. The self-emo- tional consistence effect gives support for the special load theory. Study 1 manipulated types of working memory load （self-positive load, self-negative load, no load） and showed that there indeed exist the self-emotional consis- tence effect. Study 2 regulated the reaction time of the cognitive task and proved that this effect is reversible. These results gave supports for the perspectives that there are multiple pools of resources.
