在开发熟练表现的运动编程理论时，有人建议程序中的抽象结构表示指定一系列响应和该序列的表达特征，例如时间、重音和语调，这些特征分别映射到响应输出中。在不需要表达功能的打字情况下，以前假设响应时间更简单地由提供随机规则节拍的计时器来控制。向快速打字员提供了两组专门构建的文本，结果支持了熟练的打字速度是按规律的节奏进行的这一观点。他们还表明，节奏上存在系统性的偏离节拍的情况，这些偏离是由键盘移动的偶然事件引起的，但并不是这些事件的简单后果；相反，它们可以被视为对偶然事件的结构化预期，因此类似于言语和演奏音乐的表达特征。
In developing a theory of motor programming of skilled performance it has been suggested that an abstract, structural representation in the program specifies both a sequence of responses and expressive features of the sequence, such as timing, stress and intonation, which are mapped separately into the response output. In the case of typing, which does not require expressive features, it has previously been assumed that response timing is governed more simply by a timekeeper providing a stochastically regular beat. Two sets of specially constructed texts were given to a fast typist and the results support the idea that skilled typing is paced by a regular beat. They also show that there were systematic rhythmic departures from the beat, which arose from contingencies of keyboard movement but were not the simple consequences of these; rather they may be regarded as structured anticipations of the contingencies, and as such are analogous to the expressive features of speech and playing music.
