摘要： 在对视觉工作记忆容量资源的分配模式进行解释时, 出现了两种不同的观点, 分别是工作记忆容量的“插槽模型”和“灵活资源模型”。近期的研究结果表明, 这两种模型各有其合理之处, 而将两者融合的“插槽-资源”模型则似乎能对现有证据做出更好的解释。认知神经科学技术的引入在验证这些理论模型的过程中起到了重要作用。借助能够反映当前工作记忆负荷的生理学指标, 研究者得以更直观地观测到工作记忆容量资源的分配方式。

Abstract: Slot models and flexible resource models are two kinds of viewpoints that explain how visual working memory capacity is allocated. According to recent studies, these two kinds of capacity models are both partially reasonable, and the “slot-resource” models integrating both of them seem to explain the existing evidence much better. In testing these models, the technology of cognitive neuroscience has played an important role. With the help of physiological index which is sensitive to working memory load, researchers can observe the allocation pattern of visual working memory capacity more directly.
