Although this special issue reveals some promising achievements, most of the contributions show that tasks of implicit learning are not or are only weakly correlated with each other, and they have inconsistent predictive power on L2 acquisition. This commentary examines four possible explanations for this surprising pattern: The (suboptimal) selection of tasks, the low reliability of measures, the deep influence of the starting level even for nominally “new” implicit tasks, and the fact that the mastery of L2 may involve other implicit processes than implicit learning measured through laboratory tasks.

为什么隐式语言能力的分量结构如此难以捕捉？

尽管本期特刊揭示了一些有希望的成就，但大多数贡献表明，内隐学习的任务之间没有或只是弱相关，并且它们对 L2 习得的预测能力不一致。这篇评论对这种令人惊讶的模式进行了四种可能的解释：任务的（次优）选择、测量的低可靠性、即使对于名义上的“新”隐式任务，起始水平的深刻影响，以及掌握 L2 可能除了通过实验室任务测量的内隐学习之外，还涉及其他内隐过程。
