本研究探讨了虐待的影响，在第一年的生活对神经相关的处理面部表情的情绪在30个月大。研究了儿童被动观看标准化的女性模特图片时的事件相关电位（ERP）。4个ERP波形成分：早期负波（N150），早期正波（P260），负中央波（Nc）和正慢波（PSW）。一组35虐待和24 nonmaltreated儿童之间的这些波形的差异进行了报道。两组在早期知觉负性成分（N150）上没有差异，而受虐待的儿童在观看愤怒的面部表情时，与未受虐待的儿童相比，其额叶导联的P260振幅更大。对于Nc分量，nonmaltreated比较儿童表现出更大的幅度，而观看图片的快乐的面孔相比，愤怒和中性的面孔，而虐待儿童表现出更大的Nc幅度在中央网站，而观看愤怒的面孔。对于PSW，与虐待组相比，非虐待组在右半球对观看愤怒面部表情的反应中表现出更大的面积分数。研究结果在大脑发育和功能方面进行了讨论，以及它们对预防干预措施的设计和评估的影响，这项研究得到了美国国家精神卫生研究所（MH 067792 -02）和Spunk Fund，Inc.的赠款。但丁·西凯蒂我们衷心感谢Rafael Klorman博士和Karen La Due在Mt.希望家庭中心，这是用来进行这项研究。此外，我们感谢Sheree L博士提供的支持和建议。Toth和Fred A.罗格施此外，我们还要感谢凯伦·拉杜、史蒂夫·佩里诺和香农·奥哈拉，以及山的其他工作人员。希望家庭中心，为他们在数据收集方面的援助。最后，我们永远感谢那些参与这项研究的家庭。
This investigation examined the effects of maltreatment during the first year of life on the neural correlates of processing facial expressions of emotion at 30 months of age. Event-related potentials (ERPs) in response to children passively viewing standardized pictures of female models posing angry, happy, and neutral facial expressions were examined. Four ERP waveform components were derived: early negative (N150), early positive (P260), negative central (Nc), and positive slow wave (PSW). Differences in these waveforms between a group of 35 maltreated and 24 nonmaltreated children were reported. The groups did not differ on the early perceptual negative component (N150), whereas the maltreated children had greater P260 amplitude at frontal leads compared to the nonmaltreated children in response to viewing angry facial expressions. For the Nc component, the nonmaltreated comparison children exhibited greater amplitude while viewing pictures of happy faces compared to angry and neutral faces, whereas the maltreated children showed greater Nc amplitude at central sites while viewing angry faces. For the PSW, the nonmaltreated group showed a greater area score in the right hemisphere in response to viewing angry facial expressions compared to the maltreated group. The results are discussed in terms of brain development and function, as well as their implications for the design and evaluation of preventive interventions.This research was supported by grants from the National Institute of Mental Health (MH067792-02) and the Spunk Fund, Inc. to Dante Cicchetti. We gratefully acknowledge the technical assistance of Rafael Klorman, PhD, and Karen La Due in setting up the ERP laboratory at Mt. Hope Family Center, which was used to carry out this study. Moreover, we appreciate the support and advice provided by Drs. Sheree L. Toth and Fred A. Rogosch. In addition, we are grateful to Karen La Due, Steve Perino, and Shannon O'Hara, as well as other staff at Mt. Hope Family Center, for their assistance in data collection. Finally, we are eternally grateful to those families who participated in this research.
