过去的研究已经证明了通过脑电图功率测量的皮质活动与婴儿期认知过程之间的联系。在另一项研究中，家庭社会经济地位（SES）与儿童的早期认知发展密切相关，在生命的第二年，语言和陈述性记忆技能方面出现了社会经济差异。本研究以足月婴儿为样本，考察了出生时静息脑电图功率、SES 以及 15 个月大的语言和记忆技能之间的关联。结果表明出生时 SES 和脑电图功率之间没有关联。然而，出生时的脑电图功率与 15 个月大时的语言和记忆结果相关。具体来说，额叶功率 (24–48 Hz) 与后来的视觉配对比较 (VPC) 记忆得分呈正相关。顶叶区域的功率 (24–35 Hz) 与后来的 PLS 听觉理解语言分数呈正相关。这些发现表明，SES 的大脑活动差异在出生时可能并不明显，但新生儿静息脑电图功率的测量与后期记忆和语言技能相关，与 SES 无关。
Past research has demonstrated links between cortical activity, measured via EEG power, and cognitive processes during infancy. In a separate line of research, family socioeconomic status (SES) has been strongly associated with children’s early cognitive development, with socioeconomic disparities emerging during the second year of life for both language and declarative memory skills. The present study examined associations among resting EEG power at birth, SES, and language and memory skills at 15-months in a sample of full-term infants. Results indicate no associations between SES and EEG power at birth. However, EEG power at birth was related to both language and memory outcomes at 15-months. Specifically, frontal power (24–48 Hz) was positively correlated with later Visual Paired Comparison (VPC) memory scores. Power (24–35 Hz) in the parietal region was positively correlated with later PLS-Auditory Comprehension language scores. These findings suggest that SES disparities in brain activity may not be apparent at birth, but measures of resting neonatal EEG power are correlated with later memory and language skills independently of SES.
