What are the factors responsible for skilled typing performance, and do they change with the age of the typist? These questions were addressed in two studies by examining time and accuracy of keystrokes in a variety of typinglike activities among typists ranging in speed from 17 to 104 net words per minute and ranging in age from 19 to 72 years old. Typing skill was related to the temporal consistency of making the same keystroke, the efficiency of overlapping successive keystrokes, the speed of alternate-hand tapping, and the number of characters of to-be-typed text required to maintain a normal rate of typing. Older typists were slower in tapping rate and in choice reaction time but were not slower in speed of typing, apparently because they were more sensitive to characters farther in advance of the currently typed character than young typists.
熟练打字表现的影响因素有哪些，这些因素会随着打字员年龄的增长而变化吗？在两项研究中，通过考察打字速度从每分钟净打17个单词到104个单词、年龄从19岁到72岁的打字员在各种类似打字活动中的击键时间和准确性，对这些问题进行了探讨。打字技能与进行相同击键的时间一致性、连续击键重叠的效率、交替手敲击的速度以及维持正常打字速度所需的待输入文本的字符数有关。年长的打字员敲击速度和选择反应时间较慢，但打字速度并不慢，显然是因为他们比年轻打字员对当前正在输入字符之前更远的字符更敏感。
