听觉统计学习的先前研究通常为学习者提供均匀分布在整个暴露语料库中的顺序结构信息。在这里，我们提出了学习者的非均匀分布的结构信息，改变组织的三音节无意义的话在中游。当这种结构变化没有被低水平的声音提示标记时，或者即使被音高变化提示时，也只学会了两种结构中的第一种。然而，这两种结构的学习时，有一个明确的线索，以中游的变化，或当暴露于第二个结构的时间增加了两倍。这些结果表明，在听觉统计学习任务中成功提取的结构降低了学习后续结构的能力，除非两个结构的存在被明确标记或暴露于第二个是相当长的时间。学习者检测和使用分布信息的变化，以保持对多个结构的敏感性的机制进行了讨论，从行为和计算的角度。
Previous studies of auditory statistical learning have typically presented learners with sequential structural information that is uniformly distributed across the entire exposure corpus. Here we present learners with nonuniform distributions of structural information by altering the organization of trisyllabic nonsense words at midstream. When this structural change was unmarked by low-level acoustic cues, or even when cued by a pitch change, only the first of the two structures was learned. However, both structures were learned when there was an explicit cue to the midstream change or when exposure to the second structure was tripled in duration. These results demonstrate that successful extraction of the structure in an auditory statistical learning task reduces the ability to learn subsequent structures, unless the presence of two structures is marked explicitly or the exposure to the second is quite lengthy. The mechanisms by which learners detect and use changes in distributional information to maintain sensitivity to multiple structures are discussed from both behavioral and computational perspectives.
