Almost one-third of the participants in a neuropsychological study signed the consent form below the given line. The relationship between a signature position on or below the line and participants' cognitive function was investigated. Fifty drug-dependent individuals, 50 of their siblings, and 50 unrelated control participants completed a battery of neuropsychological tests using the Cambridge Neuropsychological Test Automated Battery (CANTAB). Individuals signing below, rather than on, the line performed more poorly on tests of visuospatial memory, but no differently on other cognitive tests. Signature positioning may be a soft sign for impairment of the mechanisms involved in visuospatial memory.
在一项神经心理学研究中，近三分之一的参与者在给定横线下方签署了同意书。研究了签名位置在横线上方或下方与参与者认知功能之间的关系。50名药物依赖者、他们的50名兄弟姐妹以及50名无亲属关系的对照参与者使用剑桥神经心理测试自动成套系统（CANTAB）完成了一系列神经心理学测试。在视觉空间记忆测试中，在横线下方而非上方签名的个体表现更差，但在其他认知测试中没有差异。签名位置可能是视觉空间记忆相关机制受损的一个软指标。
