Individual differences in processing speed and executive attention have both been proposed as explanations for individual differences in cognitive ability, particularly general and fluid intelligence (Engle et al., 1999; Kail & Salthouse, 1994). Both constructs have long intellectual histories in scientific psychology. This article attempts to describe the historical development of these constructs, particularly as they pertain to intelligence. It also aims to determine the degree to which speed and executive attention are theoretical competitors in explaining individual differences in intelligence. We suggest that attention is the more fundamental mechanism in explaining variation in human intelligence. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

处理速度和执行注意力是智力的原因。

处理速度和执行注意力的个体差异都被提出作为认知能力个体差异的解释，特别是一般智力和流体智力（Engle 等人，1999；Kail 和 Salthouse，1994）。这两种结构在科学心理学中都有悠久的思想历史。本文试图描述这些概念的历史发展，特别是它们与智力相关的概念。它还旨在确定速度和执行注意力在解释智力个体差异方面理论上的竞争程度。我们认为注意力是解释人类智力变异的更基本机制。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
