在这项研究中，我们调查的作用，注意力，序列结构，效应特异性在学习结构化的动作序列。实验1表明，简单的结构化序列可以在注意力分散的情况下学习。学习不受干扰任务难度变化的影响，受试者似乎没有意识到结构。结构化序列知识从手指产生转移到手臂产生（实验2），表明序列规范存在于效应子独立系统中。实验3和4表明，只有具有至少一些独特关联的结构（例如，与15243号建筑的联系或结构143132中的4到3.）在注意力分散的情况下也能学到。所有项目在结构的不同部分以不同顺序重复的结构（例如，序列132312.）需要注意学习。这样的结构可能需要分层表示，其中的建设需要注意。
In this study we investigated the role of attention, sequence structure, and effector specificity in learning a structured sequence of actions. Experiment 1 demonstrated that simple structured sequences can be learned in the presence of attentional distraction. The learning is unaffected by variation in distractor task difficulty, and subjects appear unaware of the structure. The structured sequence knowledge transfers from finger production to arm production {Experiment 2), suggesting that sequence specification resides in an effector-independent system. Experiments 3 and 4 demonstrated that only structures with at least some unique associations (e.g., any association in Structure 15243... or 4 to 3 in Structure 143132...) can be learned under attentional distraction. Structures with all items repeated in different orders in different parts of the structure (e.g., Sequence 132312...) require attention for learning. Such structures may require hierarchic representation, the construction of which takes attention.
