本文研究了兴奋剂对老年人信息加工的影响。在实验一中，哌甲酯（MP）的效果进行了检查，在8个年轻和8个老年妇女使用的任务（Sers），其中刺激和反应的复杂性是不同的。MP加快了年轻女性的处理速度，但对老年女性没有影响。然后进行第二个实验以分离年龄刺激效应。在实验2中，研究了MP和10 mg d-苯丙胺（DAMP）对12名青年和12名老年男性不同类型信息加工的影响。刺激物改变了两组的连续性能任务的性能。这两种兴奋剂都加快了年轻人对Sers的处理，但对老年人没有。然而，MP在两组中加快了响应处理任务的处理。研究结果表明，兴奋剂作用于反应处理，并且似乎有几个这样的过程。其中一些阶段随着年龄的增长而下降，而另一些则不会
The effects of stimulant drug on information processing in elderly adults was studied. In experiment I, the effect of methylphenidate (MP) was examined in 8 young and 8 elderly women using a task (SERS) in which stimulus and response complexities were varied. MP speeded processing in the young but not in the elderly women. A second experiment was then conducted to isolate the age-stimulant effects. In experiment 2, the effects of MP and 10 mg of d-amphetamine (DAMP) were studied in 12 young and 12 elderly men on different types of information processing. Stimulants changed performance on a continuous performance task in both groups. Both stimulants speeded processing on SERS in young, but not in elderly men. MP, however, speeded processing in both groups on a response processing task. The findings suggest that stimulants act on response processing and there appear to be several such processes. Some of these stages decline with age whereas others do not
