脑电图的时频分析越来越多地用于研究支持语言理解的神经振荡。尽管这种方法对发展研究很有希望，但大多数现有的工作都集中在成年人身上。特别是Theta功率（4 - 8hz）通常对应于孤立的单词和正在进行的文本的语义处理。本研究考察了儿童和青少年（8-15岁）在书面句子加工过程中对单个单词的θ波参与时间和地形的变化。结果表明，从地形上看，θ波反应在儿童中分布广泛，发生在左右中央后区和正中额区，到青少年时定位于左侧中央后区。有两个显著的发展转变。首先，在8 - 9岁和10-11岁之间，对每个单词的反应，额叶区域的早期（150-300毫秒）θ波活动显著减少。第二，在整个句子中，10 - 11岁和12-13岁儿童的右顶叶区域的θ波参与显著减少，与青少年相比，幼儿的θ波反应在单词之间保持显著升高。我们发现12 - 13岁和14-15岁之间没有显著差异。这些发现表明，儿童在句子处理过程中对语言网络的参与在童年中期持续变化，但在青春期稳定下来。
Time frequency analysis of the EEG is increasingly used to study the neural oscillations supporting language comprehension. Although this method holds promise for developmental research, most existing work focuses on adults. Theta power (4–8 Hz) in particular often corresponds to semantic processing of words in isolation and in ongoing text. Here we investigated how the timing and topography of theta engagement to individual words during written sentence processing changes between childhood and adolescence (8–15 years). Results show that topographically, the theta response is broadly distributed in children, occurring over left and right central-posterior and midline frontal areas, and localizes to left central-posterior areas by adolescence. There were two notable developmental shifts. First, in response to each word, early (150–300 msec) theta engagement over frontal areas significantly decreases between 8 and 9 years and 10–11 years. Second, throughout the sentence, theta engagement over the right parietal areas significantly decreases between 10 and 11 years and 12–13 years with younger children’s theta response remaining significantly elevated between words compared to adolescents’. We found no significant differences between 12 and 13 years and 14–15 years. These findings indicate that children’s engagement of the language network during sentence processing continues to change through middle childhood but stabilizes into adolescence.
