In the Wechsler system the Arithmetic subtest has been viewed as a measure of concentration, working memory, or freedom from distractibility. However, a wide range of other influences on Arithmetic performance has been proposed. The current study was intended to examine these to further characterize what is measured by the Arithmetic subtest. Participants were 118 adults referred for neuropsychological assessment. The results indicate a strong association between WAIS-III Arithmetic and the other WMI (Working Memory Index) subtests. Arithmetic also showed a high association with Arithmetic skill and verbal memory. Moderate contributions to Arithmetic performance were found for most other cognitive measures. Measures of anxiety and of background factors, such as perceived difficulty learning Arithmetic, were weakly related to Arithmetic scores. These results suggest that although Arithmetic may be considered a measure of concentration or working memory, many other factors influence it and its specificity as a concentration measure is limited.
在韦氏智力量表体系中，算术分测验一直被视为注意力集中程度、工作记忆或不受分心影响能力的一种测量方式。然而，人们也提出了一系列对算术成绩产生影响的其他因素。当前的这项研究旨在对这些因素进行考察，以便进一步明确算术分测验所测量的内容。研究参与者为118名被转介接受神经心理学评估的成年人。结果表明，韦氏成人智力量表第三版（WAIS-III）算术分测验与其他工作记忆指数（WMI）分测验之间存在很强的关联。算术分测验还与算术技能和言语记忆高度相关。大多数其他认知测量指标对算术成绩有中等程度的贡献。焦虑测量指标以及诸如感知到的算术学习难度等背景因素与算术分数的相关性较弱。这些结果表明，尽管算术分测验可以被视为注意力集中程度或工作记忆的一种测量方式，但许多其他因素也会对其产生影响，并且它作为注意力集中程度测量方式的特异性是有限的。
