Clock-drawing tests are simple and rapid screening devices for dementia. It was observed that individuals <60 years of age showed similar performance with a digital prompt (" . . .make the clock read 12:45") or an analog prompt (" . . .quarter to 1"), whereas individuals >70 years of age showed improved performance with an analog prompt. The digital prompt has routinely been used to force participants to recode the prompt via conceptualization. Differential scoring across a range of ages has likely derived from the advent and increase of digital clocks with the younger segment of the population. This implies the need for as-yet undetermined alteration in the nature of prompts to force recoding as the current younger population ages.
画钟测试是用于痴呆症的简单快速筛查工具。据观察，60岁以下的个体在数字提示（“……使时钟显示为12:45”）或模拟提示（“……差一刻到1点”）下表现相似，而70岁以上的个体在模拟提示下表现更好。数字提示通常用于迫使参与者通过概念化对提示进行重新编码。不同年龄段的差异评分可能源于数字时钟的出现和增加，年轻人群体接触数字时钟更多。这意味着随着当前年轻人群体的老龄化，需要对提示的性质进行尚未确定的改变，以迫使重新编码。
