In the present experiment, we examined slowing of the individual key presses of a familiar keying sequence by four different versions of a concurrent tone counting task. This was done to determine whether the same cognitive processor that has previously been assumed by the dual processor model (DPM) to initiate familiar keying sequences and assist in their execution, is involved also in the central processes of a very different task (viz. identifying tones and counting target tones). The present results confirm this hypothesis. They also suggest that in this particular situation the central processing resources underlying the cognitive processor can be distributed across the central processes of different tasks in a graded manner, rather than that they continue to behave like a single, central processor that serially switches between the central processes of the concurrently performed tasks. We argue that the production of highly practiced movement sequences can be considered automatic in the sense that execution of familiar movement sequences can continue without cognitive control once they have been initiated.
在本实验中，我们通过四种不同版本的并发音调计数任务，研究了熟悉的按键序列中各个按键按下动作的减慢情况。这样做是为了确定双处理器模型（DPM）先前假定的启动熟悉按键序列并协助其执行的同一认知处理器，是否也参与了一项截然不同任务（即识别音调并对目标音调进行计数）的核心过程。目前的结果证实了这一假设。它们还表明，在这种特定情况下，认知处理器所基于的核心处理资源可以以分级的方式分布在不同任务的核心过程中，而不是像单个核心处理器那样在并发执行任务的核心过程之间进行串行切换。我们认为，高度熟练的动作序列的产生在某种意义上可以被视为自动的，即一旦启动，熟悉动作序列的执行可以在没有认知控制的情况下继续进行。
