本文对13名7 ~ 12个月婴儿的头皮记录脑电图（EEG）变化与成功完成2项额叶功能性认知任务能力的发展之间的关系进行了研究。婴儿成功地完成了A-非B任务，并且在一岁后半期的延迟时间越来越长，这表明头皮记录的额区脑电活动的功率发生了变化，并且前/后EEG相干性增加。快速掌握物体提取的婴儿在额叶脑电发育方面与物体提取表现正常的婴儿没有差异。在一项检查抑制达到一个新的玩具的任务中，有额叶脑电图作为性能的函数没有差异。横断面样本的结果显示了类似的发现。这些数据证实了非人灵长类动物在成功完成某些任务（A-而不是B）时额叶皮层成熟的重要性，但没有证实非人灵长类动物在完成其他任务（物体提取）时额叶皮层的重要性。这些数据还表明，脑电图可能是有用的，作为一个非侵入性措施的中枢神经系统的发展，在第一年的生活。
The relations between changes in the scalp-recorded electroencephalogram (EEG) and the development of the ability to perform successfully 2 cognitive tasks attributed to frontal lobe functioning were examined in 13 infants from 7 to 12 months of age. Infants successful in performing the A-not-B task with increasingly longer delays across the second half of the first year of life showed changes in power in scalp-recorded brain electrical activity in the frontal region and an increase in anterior/posterior EEG coherence. Infants with rapid mastery of object retrieval did not differ in frontal EEG development from infants who exhibited the normal developmental progression in object retrieval performance. In a task examining inhibition of reaching to a novel toy, there were no differences in frontal EEG as a function of performance. Results from a cross-sectional sample revealed similar findings. These data confirm work with nonhuman primates on the importance of maturation of frontal cortex in the successful performance on certain tasks (A-not-B), but do not confirm nonhuman primate data on the importance of frontal cortex for other tasks (object retrieval). The data also suggest that the electroencephalogram may be useful as a noninvasive measure of central nervous system development during the first year of life.
