口语是由一个复杂的、按顺序排列的信号组成的，其中包含的模式可以用语言单位之间的统计关系来描述。以往的研究表明，学习结构化序列模式的领域能力可能是语言习得的基础。为了验证这一预测，我们研究了听力成年人的概率结构模式的内隐序列学习在多大程度上与降级听力条件下的口语句子感知任务相关。句子知觉任务的表现被发现与内隐序列学习相关，但只有当序列是由容易口头编码的刺激组成。因此，语音序列的内隐学习似乎是口头语言处理的基础，并可能表明一个迄今尚未探索的认知因素，可能会解释巨大的变异性，在失聪儿童的语言结果与人工耳蜗植入。目前的研究结果强调了调查个体差异的重要性，在特定的认知能力作为一种方式来理解和解释语言在聋人学习者，特别是在语言的变化结果人工耳蜗植入术。
Spoken language consists of a complex, sequentially arrayed signal that contains patterns that can be described in terms of statistical relations among language units. Previous research has suggested that a domain-general ability to learn structured sequential patterns may underlie language acquisition. To test this prediction, we examined the extent to which implicit sequence learning of probabilistically structured patterns in hearing adults is correlated with a spoken sentence perception task under degraded listening conditions. Performance on the sentence perception task was found to be correlated with implicit sequence learning, but only when the sequences were composed of stimuli that were easy to encode verbally. Implicit learning of phonological sequences thus appears to underlie spoken language processing and may indicate a hitherto unexplored cognitive factor that may account for the enormous variability in language outcomes in deaf children with cochlear implants. The present findings highlight the importance of investigating individual differences in specific cognitive abilities as a way to understand and explain language in deaf learners and, in particular, variability in language outcomes following cochlear implantation.
