我们调查了重复的效果识别直立，倒置和对比度反转的目标面孔在8至15岁的儿童从事学习阶段/测试阶段的范式与目标和分心面孔。分析了早期（P1，N170）和晚期ERP成分。不同年龄段的孩子表现都一样好，而且更善于识别直立的面孔。然而，青少年和成年人对所有三种面孔类型的准确性相同。对直立、倒置和消极面孔的神经生理反应一直到成年才成熟，并在不同年龄表现出不同的效应。PI和N170成分在所有年龄都受到脸型的影响，这表明无论年龄如何，编码过程都存在早期破坏。额叶ERPs反映了处理这些刺激的难度。在额叶、颞额叶和顶叶部位观察到明显的重复效应，表明这些大脑区域参与了工作记忆和识别过程。因此，一个学习阶段足以（a）让8岁的孩子像15岁的孩子一样准确地完成任务，（B）消除青少年和成年人的面孔类型效应，但对年幼的孩子来说则不然。
We investigated the effect of repetition on recognition of upright, inverted and contrast-reversed target faces in children from 8 to 15 years when engaged in a learning phase/test phase paradigm with target and distractor faces. Early (P1, N170) and late ERP components were analysed. Children across age groups performed equally well, and were better at recognizing upright faces. However, teenagers and adults were equally accurate for all three face types. The neurophysiological responses to upright, inverted and negative faces matured until adulthood and showed different effects at different ages. PI and N170 components were affected by face type at all ages, suggesting early configural disruption on encoding processes regardless of age. Frontal ERPs reflected the difficulty of processing these stimuli. Distinct repetition effects were seen at frontal, temporal frontal and parietal sites, suggesting differential involvement of these brain regions underlying working memory and recognition processes. Thus, a learning phase was sufficient (a) for 8-year-olds to perform as accurately as 15-year-olds and (b) to eliminate face type effects in teenagers and adults, but not in younger children.
