In keyboard writing, typing skills are considered an important prerequisite of proficient text production. We describe the design, implementation, and application of a standardized copy-typing task in order to measure and assess individual typing fluency. A test-retest analysis indicates the instrument’s reliability. While the task has been developed across eleven different languages and the related keyboard layouts, we here refer to a corpus of Dutch copy tasks (n = 1682). Analyses show that copying speed non-linearly varies with age. Bayesian analyses reveal differences in the typing performance and the underlying distributions of inter-key intervals between the different task components (e.g., lexical vs. non-lexical materials; high-frequent vs. lowfrequent bigrams). Based on these findings it is strongly recommended to include copy-task measures in the analysis of keystroke logging data in writing studies. This supports a better comparability and interpretability of keystroke data from more complex or communicatively-embedded writing tasks across individuals. Further potential applications of the copy task for writing research are explained and discussed.

在写作研究中测量和评估打字技巧

在键盘写作中，打字技巧被认为是熟练文本制作的重要先决条件。我们描述了标准化复制打字任务的设计、实现和应用，以测量和评估个人打字流畅度。重测分析表明仪器的可靠性。虽然该任务已经开发了十一种不同的语言和相关的键盘布局，但我们在这里指的是荷兰语复制任务的语料库（n = 1682）。分析表明，复印速度随年龄非线性变化。贝叶斯分析揭示了打字性能的差异以及不同任务组件之间键间间隔的基本分布（例如，词汇与非词汇材料；高频与低频二元组）。基于这些发现，强烈建议在写作研究中的击键记录数据分析中包括复制任务测量。这支持对来自更复杂或嵌入通信的个人书写任务的击键数据进行更好的可比性和可解释性。解释和讨论了复制任务在写作研究中的进一步潜在应用。
