This study investigated whether a target sequence that people intend to learn is learned selectively when it is interleaved with another (non-target) sequence. Three experiments used a serial reaction time task in which different spatial and color stimuli occurred alternately. Each of the two interleaved sequences had structural regularity. Participants in an intentional learning group were instructed to learn the target (spatial) sequence whereas those in an incidental learning group were not. In Experiments 1 and 2 spatial and color sequences were correlated. Results showed that the intentional group learned the spatial sequence better than the incidental group and learned it independently of the color sequence, whereas the incidental group learned the two sequences as a combined sequence. In Experiment 3 the sequences were uncorrelated. Results showed that the intentional group was no longer superior in learning the spatial sequence. Findings indicate that the intention to learn a target sequence enables selective learning of it only when it is correlated with a non-target sequence.
本研究旨在探讨当目标序列与另一个（非目标）序列交织时，人们是否会有选择性地学习目标序列。三个实验使用了序列反应时间任务，其中不同的空间和颜色刺激交替出现。两个交织序列中的每一个都具有结构规律性。意图学习组的参与者被指示学习目标（空间）序列，而偶然学习组的参与者则没有。在实验 1 和 2 中，空间和颜色序列是相关的。结果表明，意图学习组比偶然学习组更好地学习了空间序列，并且独立于颜色序列进行学习，而偶然学习组则将两个序列作为一个组合序列进行学习。在实验 3 中，序列是不相关的。结果表明，意图学习组在学习空间序列方面不再具有优势。研究结果表明，只有当目标序列与非目标序列相关时，意图学习才能使目标序列得到有选择性的学习。
