两个实验考察了视觉编码和手动运动编程在复印过程中的效果。在实验1中，专家打字员抄写包含高频或低频目标词的句子；指令强调打字速度或文本理解。结果表明，在理解条件下，单词优先于低频目标的打字次数增加。然而，当强调打字速度时，前目标打字不受目标频率的影响，这表明文本的视觉编码不影响同时按键。低频词本身的打字速度比高频词慢。补充分析表明，词频可能会影响构成一个词的一系列击键的编程。与这一评估相一致的是，实验2表明词频的影响不能减少到移动练习中。
Two experiments examined effects of visual encoding and of manual motor programming during copytyping. In Experiment 1, expert typists copied sentences containing high-or low-frequency target words; instructions emphasized either the speed of typing or text comprehension. The results showed increased typing times for words preceding low frequency targets in the comprehension condition. However, pretarget typing was not affected by target frequency when speed of typing was emphasized, indicating that the visual encoding of text does not affect concurrent keypresses. Low-frequency words themselves were typed slower than high-frequency words. Supplementary analyses indicated that word frequency may affect the programming of a sequence of keystrokes forming a word. Consistent with this assessment, Experiment 2 showed that effects of word frequency cannot be reduced to movement practice.
