Abstract

The common requirement to set the time to "10 past 11" on the Clock Drawing Test is intended to elicit a stimulus bound response (SBR), in which the responder is "pulled" to the salient stimulus "10," resulting in hands set at "10 before 11." SBRs are considered markers of executive dysfunction, although this assumption has not yet been validated. We compared SBR and other time-setting errors on inhibitory control tests, hypothesizing that they represent related constructs. The role of semantic dysfunction in the formation of those errors was also investigated. We examined baseline test performance of participants with Mild Cognitive Impairment or a history of depression, and control participants, enrolled in a dementia prevention study. Among 258 participants, we identified clocks with SBRs (n = 16), other time errors (n = 22), or no errors at all (n = 42). Performance between the groups with SBRs and other time-setting errors did not differ on any of the executive tests, and both error groups performed significantly worse than the No Error group on the semantic tests. Control for covariates further supported semantic and executive components in time-setting errors. Both semantic and inhibitory control deficits may underlie time representation errors in general.

时钟绘制测试中的时间设定错误与语义和执行障碍有关。
在时钟画图测验中,将时间设定为 "11 点过 10 分 "的常见要求旨在诱发刺激约束反应(SBR),即反应者被 "牵引 "到突出刺激 "10 "处,导致双手设定在 "11 点前 10 分"。SBR 被认为是执行功能障碍的标志,尽管这一假设尚未得到验证。我们比较了抑制控制测试中的SBR和其他时间设定错误,假设它们代表了相关的结构。我们还研究了语义功能障碍在这些错误形成中的作用。我们对参加痴呆症预防研究的轻度认知障碍或有抑郁症病史的参与者和对照组参与者的基线测试表现进行了研究。在 258 名参与者中,我们发现了有 SBRs(16 人)、其他时间错误(22 人)或完全没有错误(42 人)的时钟。在任何一项执行测试中,时间设定错误组和其他时间设定错误组的表现均无差异,而在语义测试中,两个错误组的表现均明显差于无错误组。对协变量的控制进一步支持了时间设定错误中的语义和执行成分。语义和抑制控制缺陷可能是时间表征错误的普遍原因。
