Abstract: 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 involved in different brain areas, this series of research adopted a revised version of reading span paradigm to investigate whether there exists the self-emotional consistence effect, and whether this effect is reversible. The self-emotional 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-emotional 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 consistence 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.

Key words: working memory, working memory load, self-emotional consistence effect, load theory.

摘要： 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。
