本研究通过潜变量分析检验了次级记忆过程解释工作记忆容量和流体智力之间相关性的说法。在本研究中，参与者对次级记忆、工作记忆容量和流体智力进行了多种测量。结构方程模型表明，二级记忆和工作记忆容量都是流体智力的独特差异。这些结果与最近的说法不一致，即工作记忆容量并不能解释流体智力的变化，而不仅仅是次级记忆。相反，研究结果与工作记忆容量模型一致，这些模型表明，需要维持和提取过程来解释工作记忆容量与流体智力之间的实质性关系。
The present study examined the claim that secondary memory processes account for the correlation between working memory capacity and fluid intelligence via a latent variable analysis. In the present study, participants performed multiple measures of secondary memory, working memory capacity, and fluid intelligence. Structural equation modeling suggested that both secondary memory and working memory capacity account for unique variance in fluid intelligence. These results are inconsistent with recent claims that working memory capacity does not account for variance in fluid intelligence over and above what is accounted for by secondary memory. Rather, the results are consistent with models of working memory capacity that suggest that both maintenance and retrieval processes are needed to account for the substantial relation between working memory capacity and fluid intelligence.
