越来越多的证据表明，来自低收入家庭的孩子在大脑、语言和认知发展方面表现出差异。为了更好地了解这些差异以及它们之间的关系，我们比较了45名来自低收入家庭的8-15岁儿童和45名来自高收入家庭的年龄和性别匹配的儿童的休息状态脑电，这些儿童完成了一系列语言和认知评估。来自低收入家庭的孩子在语言任务上表现得更差，在静息状态下的脑电表现出差异，包括更多的theta和更少的阿尔法能量。为了探讨语言、认知与静息状态脑电的关系，我们进行了多元回归分析。较好的工作记忆与较低的静息状态theta功率有关。阿尔法和词汇量之间存在交互作用，因此只有来自低收入家庭的儿童，较大的休息状态阿尔法与较高的词汇得分相关。当控制另一个频段的静息状态变化时，这两种关系都成立，表明它们在某种程度上是独立的影响。这些发现为学龄儿童的自尊、神经发育以及认知和语言结果提供了新的线索。
There is increasing evidence that children from low income homes exhibit differences in brain, language and cognitive development. To better understand these differences and how they relate to one another, we compared the resting state EEG of forty-five 8-15-year-olds from low-income homes and 45 age and sex matched children from higher income homes who completed a battery of language and cognitive assessments. Children from low income homes performed worse on language tasks and exhibited differences in resting state EEG including more theta and less alpha power. To investigate the relationship between language, cognition and resting state EEG we performed multiple regression analyses. Better working memory was related to lower resting state theta power. There was an interaction between alpha and vocabulary, such that only for children from low income homes, greater resting state alpha was related to higher vocabulary scores. Both relationships held when controlling for resting state changes in the other frequency band, indicating they are somewhat independent effects. These findings shed new light on SES, neural development and cognitive and language outcomes in school-aged children.
