研究婴儿的发育心理生理学家对脑电图波或节律没有普遍接受的频率定义。本研究的目的是调查 8 个月大婴儿执行空间工作记忆任务期间三个婴儿脑电图频段与任务相关的功率变化。 EEG数据分为三个频段：3-5 Hz、6-9 Hz、反10-12 Hz。尽管所有三个频段都显示出一定程度的基线与任务以及认知活动的不同处理阶段之间的区别，但只有 6-9 Hz 频段始终表现出这些能力，并区分正确和错误的反应。这些数据可以为定义适合婴儿研究参与者使用的脑电图频段以及理解这些频率在认知活动期间的功能奠定基础。
Developmental psychophysiologists working with infants have no commonly accepted frequency definitions of EEG waves or rhythms. The purpose of this study was to investigate the task-related power changes in three infant EEG frequency bands during the performance of a spatial working memory task by 8-month-old infants. EEG data were divided into three frequency bands: 3-5 Hz, 6-9 Hz, anti 10-12 Hz. Although all three frequency bands showed some level of discrimination of baseline from task and among different processing stages of cognitive activity, only the 6-9 Hz band consistently exhibited these capabilities and distinguished the correct from incorrect responses. These data may form the foundation for defining EEG frequency bands that are appropriate for use with infant research participants and for understanding the function of these frequencies during cognitive activity.
