内隐统计学习（ISL）领域当前的一个争议是，这个过程是由单个中央机制组成，还是由多个特定于模态的机制组成。为了深入了解这个问题，目前的研究涉及三个ISL实验，以探讨是否多模态输入源在每种模态中单独处理或跨模态集成在一起。在实验1中，视觉和听觉ISL的单峰条件下进行了测量，结果提供了一个基线水平的学习为后续实验。视觉和听觉序列分别呈现，两种模式使用的基础语法是相同的。在实验2中，使用相同的人工语法同时呈现视觉和听觉序列，以研究冗余的多感觉信息是否会导致促进效应（即，与基线相比，学习增加。在实验3中，视觉和听觉序列再次同时呈现，但这次每种模态采用不同的人工语法来研究干扰效应（即，与基线相比，将观察到学习减少）。结果表明，实验2中没有促进学习效应，实验3中也没有干扰学习效应。这些研究结果表明，参与者能够同时和独立地跟踪两套连续的双模态条件下。这些研究结果是一致的理论，证明存在多个，特定的模态ISL机制，而不是一个单一的中心。
A current controversy in the area of implicit statistical learning (ISL) is whether this process consists of a single, central mechanism or multiple modality-specific ones. To provide insight into this question, the current study involved three ISL experiments to explore whether multimodal input sources are processed separately in each modality or are integrated together across modalities. In Experiment 1, visual and auditory ISL were measured under unimodal conditions, with the results providing a baseline level of learning for subsequent experiments. Visual and auditory sequences were presented separately, and the underlying grammar used for both modalities was the same. In Experiment 2, visual and auditory sequences were presented simultaneously with each modality using the same artificial grammar to investigate whether redundant multisensory information would result in a facilitative effect (i.e., increased learning) compared to the baseline. In Experiment 3, visual and auditory sequences were again presented simultaneously but this time with each modality employing different artificial grammars to investigate whether an interference effect (i.e., decreased learning) would be observed compared to the baseline. Results showed that there was neither a facilitative learning effect in Experiment 2 nor an interference effect in Experiment 3. These findings suggest that participants were able to track simultaneously and independently two sets of sequential regularities under dual-modality conditions. These findings are consistent with the theories that posit the existence of multiple, modality-specific ISL mechanisms rather than a single central one.
