This article reports an investigation of how inhibition contributes to fluid reasoning when it is decomposed into the reasoning ability, item-position, and speed components to control for possible method effects. Working memory was also taken into consideration. A sample of 223 university students completed a fluid reasoning scale, two tasks tapping prepotent response inhibition, and two working memory tasks. Fixed-links modeling was used to separate the effect of reasoning ability from the effects of item-position and speed. The goodness-of-fit results confirmed the necessity to consider the reasoning ability, item-position, and speed components simultaneously. Prepotent response inhibition was only associated with reasoning ability. This association disappeared when working memory served as a mediator. Taken together, these results reflect the inhomogeneity of what is tapped by the fluid reasoning scale on one hand and, on the other, suggest inhibition as an important component of working memory.

认知加工抑制对流体推理的影响研究

本文报告了一项调查，当将抑制分解为推理能力、项目位置和速度组件以控制可能的方法效果时，抑制如何有助于流体推理。工作记忆也被考虑在内。一个由 223 名大学生组成的样本完成了流体推理量表、两项利用优势反应抑制的任务和两项工作记忆任务。固定链接建模用于将推理能力的影响与项目位置和速度的影响分开。拟合优度结果证实了同时考虑推理能力、项目位置和速度分量的必要性。优势反应抑制仅与推理能力有关。当工作记忆充当中介时，这种关联就消失了。综合起来，
