作者在这项研究中的目标是探索早期意外发现的基础，即偏好频率的手指敲击往往具有更高的频率，并且在同相任务中比反相任务更不稳定。在后续的实验中，采用了3个协议：在两种协调模式的首选频率复制，节拍器驱动的匹配的首选频率的每个协调模式，和两种模式的频率缩放。确认了首选频率的原始结果。敲击节拍器对同相和反相有不同的影响：在同相期间表现出更稳定的频率耦合。在频率缩放下，反相图案在比同相更低的频率下分解，但没有观察到相变。在这两种模式的稳定协调的损失出席手指之间的频率差和相位漂移的突然增加。根据对Haken-Kelso-Bunz模型的不对称修改，讨论了这些效应的出现（H。哈肯，J. A. S. Kelso，& H. Bunz，1985）和攻丝的任务限制。
The authors' goal in this study was to probe the basis for an earlier, unexpected finding that preferred-frequency finger tapping tends to have higher frequencies and to be less stable for in-phase than for antiphase tasks. In follow-up experiments, 3 protocols were employed: a preferred-frequency replication in both coordination modes, a metronome-driven matching of the preferred frequencies to each of the coordination modes, and a frequency scaling of both modes. The original findings were affirmed for preferred frequency. Tapping to a metronome had a differential effect on in-phase and antiphase: A more stable coupling across frequencies was exhibited during in-phase. Under frequency scaling, the antiphase pattern decomposed at lower fre- quencies than did in-phase, but no phase transitions were observed. The loss of stable coordination in both modes was attended by sudden increases in frequency differences between fingers and by phase wandering. The emergence of those effects is discussed in light of asymmetric modifications to the Haken-Kelso-Bunz model (H. Haken, J. A. S. Kelso, & H. Bunz, 1985) and the task constraints of tapping.
