许多言语理论都是用物理隐喻来描述工作记忆的,如信息流或信息容器。这些比喻通常很有用,但也可能会产生误导。本文对比了作者的三个嵌入式组件理论的计算实现理论的口头版本。分析的重点是现象,已归因于注意力集中在工作记忆。动词理论通过容器隐喻来表征注意焦点,这就产生了诸如:焦点中有多少项目?计算模型解释了同样的现象,机械地通过一个组合的项目和他们的检索线索,并启动这些线索之间的加强绑定。作者将计算模型应用于三个研究结果,这些研究结果被用来讨论注意力集中可以容纳多少项目(Oberauer和Bialkova,; Gilchrist和科万,; Oberauer和Bialkova,)。建模结果意味着这些研究结果的一个新的解释:在这些研究中的结果的不同模式并不意味着不同的能力估计的注意力的焦点,他们而是反映了在何种程度上从WM检索是并行或串行的。
Many verbal theories describe working memory (WM) in terms of physical metaphors such as information flow or information containers. These metaphors are often useful but can also be misleading. This article contrasts the verbal version of the author's three-embedded-component theory with a computational implementation of the theory. The analysis focuses on phenomena that have been attributed to the focus of attention in WM. The verbal theory characterizes the focus of attention by a container metaphor, which gives rise to questions such as: how many items fit into the focus? The computational model explains the same phenomena mechanistically through a combination of strengthened bindings between items and their retrieval cues, and priming of these cues. The author applies the computational model to three findings that have been used to argue about how many items can be held in the focus of attention (Oberauer and Bialkova,; Gilchrist and Cowan,; Oberauer and Bialkova,). The modeling results imply a new interpretation of those findings: The different patterns of results across those studies don't imply different capacity estimates for the focus of attention; they rather reflect to what extent retrieval from WM is parallel or serial.
