Spatial span (Corsi's block-tapping test) and verbal spans for digits (Wechsler Digits Forward Test) and for words were measured in 30 normal subjects and in 51 demented patients, divided into two groups (mildly demented and severely demented) according to selective clinical and neuropsychological criteria. Statistical analysis showed significant differences among the three groups for spatial span. By contrast, controls' and mildly demented patients' performances on both verbal spans were not significantly different. These findings are discussed in the light of theory about working memory.
对30名正常受试者以及51名痴呆患者进行了空间广度（科西方块敲击测试）、数字言语广度（韦氏数字顺背测验）和词语言语广度的测量。根据选择性临床和神经心理学标准，将痴呆患者分为两组（轻度痴呆和重度痴呆）。统计分析表明，三组在空间广度上存在显著差异。相比之下，对照组和轻度痴呆患者在两种言语广度上的表现没有显著差异。根据工作记忆理论对这些发现进行了讨论。
