反应时间（RTs）变慢，并且随着年龄的增长变得更加多变。研究样本通常很小，有偏见，年龄范围有限。因此，人们对这种变化的精确模式知之甚少，而关于性别差异的证据则模棱两可。作者重新分析了英国健康与生活方式调查中7130名成年参与者的数据，该调查最初由F. A. Huppert（1987）报道。作者在简单和四选项反应时间均值和变异性上建立了年龄差异模型，并测试了性别差异。简单放疗在50岁之前几乎没有减慢，而选择放疗在整个成年年龄范围内减慢。选择RT变异性的老化是其均值和错误率的函数。有显著的性别差异，最显著的是选择RT变异性。
Reaction times (RTs) slow and become more variable with age. Research samples are typically small, biased, and of restricted age range. Consequently, little is known about the precise pattern of change, whereas evidence for sex differences is equivocal. The authors reanalyzed data for 7,130 adult participants in the United Kingdom Health and Lifestyle Survey, originally reported by F. A. Huppert (1987). The authors modeled the age differences in simple and 4-choice reaction time means and variabilities and tested for sex differences. Simple RT shows little slowing until around 50, whereas choice RT slows throughout the adult age range. The aging of choice RT variability is a function of its mean and the error rate. There are significant sex differences, most notably for choice RT variability.
