Our internal clock system is predominantly dopaminergic, but memory is predominantly cholinergic. Here, we examined the common sensibility encapsulated in the statement: "time goes faster as we get older".
To measure a 2 min time interval, counted mentally in subjects of different age groups.
233 healthy subjects (129 women) were divided into three age groups: G1, 15-29 years; G2, 30-49 years; and G3, 50-89 years. Subjects were asked to close their eyes and mentally count the passing of 120 s.
The elapsed times were: G1, mean = 114.9 ± 35 s; G2, mean = 96.0 ± 34.3 s; G3, mean = 86.6 ± 34.9 s. The ANOVA-Bonferroni multiple comparison test showed that G3 and G1 results were significantly different (P < 0.001).
Mental calculations of 120 s were shortened by an average of 24.6% (28.3 s) in individuals over age 50 years compared to individuals under age 30 years.
我们的生物钟系统主要是多巴胺能的，但记忆主要是胆碱能的。在此，我们研究了“随着年龄增长，时间过得更快”这一表述中蕴含的共同感知。
测量不同年龄组受试者在心中默数的2分钟时间间隔。
233名健康受试者（129名女性）被分为三个年龄组：G1组，15 - 29岁；G2组，30 - 49岁；G3组，50 - 89岁。受试者被要求闭上眼睛，在心中默数120秒的流逝。
所经历的时间为：G1组，平均 = 114.9 ± 35秒；G2组，平均 = 96.0 ± 34.3秒；G3组，平均 = 86.6 ± 34.9秒。方差分析 - 邦费罗尼多重比较检验表明，G3组和G1组的结果有显著差异（P < 0.001）。
与30岁以下的个体相比，50岁以上的个体默数120秒的时间平均缩短了24.6%（28.3秒）。
