通过在生词出现的语境中提取联想信息来内隐学习生词是词汇增长的一个重要方面。目前的研究调查了学龄儿童和青少年如何识别句子上下文中新词的含义的神经关联。重要的是，我们考察了大脑对新词及其上下文的反应的差异作为1)外显学习成功的函数的不同，即，在学习机会后，是否能够单独正确地估计新词的含义，以及2)在我们的队列中，离线语言能力以及年龄的个体差异(N=0.82；8-16岁)。使用基于回归的分析，我们通过在同一系列模型中使用这两个指标来确定这些个体差异指标的独特影响。从我们的分析中最值得注意的发现是，在新词意义任务中，年龄和语言能力与任务相关的振荡活动之间存在特定频率的分离：语言能力与句子加工过程中任务相关的β带活动的变化有关，而年龄与假词加工过程中任务相关的theta带活动的变化有关。这些效应反映了从句子上下文映射语义的神经关联--一种重要的单词学习技能--是如何受到语言能力成熟度和年龄的独特影响的
Implicit learning about new words by picking up on associative information in the contexts they appear in is an important aspect of vocabulary growth. The current study investigated the neural correlates that underlie how school-aged children and adolescents identify the meaning of novel words embedded within sentence contexts. Importantly, we examine how differences in the brain response to novel words and their context differ as a function of 1) explicit learning success, i.e., whether novel word meanings can be correctly estimated in isolation after a learning opportunity, and 2) individual differences in offline language aptitude as well as age across our cohort (N = 82; 8–16 years). Using a regression-based analysis, we identified the unique influence of these individuals difference metrics by using both measures within the same series of models. The most notable finding from our analysis was a frequency-specific dissociation between the way age and language abilities held relationships with task-relevant oscillatory activity during the novel word meaning task: language abilities associated with task-relevant changes in beta band activity during sentence processing, while age associated with task-relevant changes in theta band activity during pseudoword processing. These effects reflect the how the neural correlates of mapping semantic meaning from sentence contexts—an important skill for word learning—is uniquely influenced by the maturity of language abilities as well as age
