年龄对反应时（RT）的影响进行了检查在2个词汇决策实验与年轻和老年人（年龄60-75）。结果表明，老年人比年轻人慢，但更准确。R.拉特克利夫（1978年）的扩散模型提供了一个很好的说明RT，他们的分布和响应精度。拟合显示80-100 ms的非决策组件的RT老年受试者相对于年轻受试者和更保守的决策标准设置老年受试者比年轻受试者的放缓。与年轻受试者相比，老年受试者的证据积累率没有显著差异（在两个实验中，老年受试者比年轻受试者高出不到2%和5%）。
The effects of aging on response time (RT) are examined in 2 lexical-decision experiments with young and older subjects (age 60-75). The results show that the older subjects were slower than the young subjects, but more accurate. R. Ratcliff's (1978) diffusion model provided a good account of RTs, their distributions, and response accuracy. The fits show an 80-100-ms slowing of the nondecision components of RT for older subjects relative to young subjects and more conservative decision criterion settings for older subjects than for young subjects. The rates of accumulation of evidence were not significantly different for older compared with young subjects (less than 2% and 5% higher for older subjects relative to young subjects in the 2 experiments).
