执行离散的运动序列通常涉及从相对缓慢的基于刺激的模式到快速模式的练习转换，在快速模式中，表现基于检索和执行整个运动组块。双处理器模型解释了（熟练的）离散按键序列在认知处理器和运动系统之间的相互作用方面的表现。在本研究中，我们在行为水平上验证并证实了该模型的核心假设。此外，我们探讨了参与的前补充运动区（pre-SMA）的离散序列技能施加抑制20分钟1-Hz离线重复经颅磁刺激（rTMS）。基于以前的工作，我们预测前SMA参与选择/启动的运动组块，这是证实了我们的研究结果。进一步观察到前SMA更多地参与更复杂的序列比简单的序列，而没有证据表明前SMA参与直接刺激-反应翻译或联想学习过程。总之，支持双处理器模型，并为前SMA参与发起的电机组块。
Executing discrete movement sequences typically involves a shift with practice from a relatively slow, stimulus-based mode to a fast mode in which performance is based on retrieving and executing entire motor chunks. The dual processor model explains the performance of (skilled) discrete key-press sequences in terms of an interplay between a cognitive processor and a motor system. In the present study, we tested and confirmed the core assumptions of this model at the behavioral level. In addition, we explored the involvement of the pre-supplementary motor area (pre-SMA) in discrete sequence skill by applying inhibitory 20 min 1-Hz off-line repetitive transcranial magnetic stimulation (rTMS). Based on previous work, we predicted pre-SMA involvement in the selection/initiation of motor chunks, and this was confirmed by our results. The pre-SMA was further observed to be more involved in more complex than in simpler sequences, while no evidence was found for pre-SMA involvement in direct stimulus–response translations or associative learning processes. In conclusion, support is provided for the dual processor model, and for pre-SMA involvement in the initiation of motor chunks.
