Eighty typists ranging in age from 21-71 years and in skill from 24-110 net words per minute participated in 2 experiments examining age-related differences in the motoric aspects of transcription typing skill. Age- and skill-related differences were examined for 2 simplified typing tasks: letter reaction time, which assessed latency to type a single keystroke, and digraph typing, which assessed the latencies to type 2 consecutive keystrokes. A finger tapping and choice reaction time task were also included. The results indicated that low-skill, older typists exhibited a deficit in both the translation and the execution components of motor performance, whereas high-skill, older typists exhibited a deficit in translation only. An additional task that manipulated preview of the text to be typed replicated the findings of Salthouse (1984), suggesting that older typists compensate for age-related slowing by beginning keystroke preparation sooner.
八十名年龄在21岁至71岁之间、打字技能在每分钟24个至110个净字数之间的打字员参与了两项实验，这些实验研究了转录打字技能在运动方面与年龄相关的差异。针对两项简化的打字任务，研究了与年龄和技能相关的差异：字母反应时间，即评估敲击单个按键的延迟；双字母打字，即评估敲击连续两个按键的延迟。还包括一项手指敲击和选择反应时间任务。结果表明，技能水平低的年长打字员在运动表现的转换和执行成分上均表现出缺陷，而技能水平高的年长打字员仅在转换方面表现出缺陷。一项对要输入文本进行预览操作的额外任务重复了索尔特豪斯（1984年）的研究结果，表明年长打字员通过更早开始按键准备来弥补与年龄相关的速度减慢。
