目的：采用事件相关电位（ERP）技术，研究了儿童和成人对面部情绪变化知觉的发展过程。方法：采用四种不同的情境：（1）N-H：一张中性面孔突然变成一张高兴面孔。(2)H-N：N-H的反向。(3)N-A：一张中性的脸突然变成了一张愤怒的脸。(4)A-N：N-A的反向。结果：在双侧后颞区，负成分引起的所有条件下，在年幼的儿童（7-10岁），年龄较大的儿童（11-14岁），和成人（23-33岁）在150-300毫秒。峰值潜伏期显着较短，振幅显着较小的成年人比年幼和年长的儿童。此外，最大振幅显着大于N-H和N-A比H-N和A-N在年幼的儿童和N-H比其他三个条件在adult.Conclusion：参与感知面部情绪变化的大脑区域还没有成熟的14 years age.Significance：我们的研究是第一个澄清儿童和成人之间的差异在感知面部情绪变化。(c)2010年国际临床神经生理学联合会。由Elsevier爱尔兰有限公司出版。保留所有权利。
Objective: The development of the perception of changes in facial emotion was investigated using event-related potentials (ERPs) in children and adults.Methods: Four different conditions were presented: (1) N-H: a neutral face that suddenly changed to a happy face. (2) H-N: reverse of N-H. (3) N-A: a neutral face that suddenly changed to an angry face. (4) A-N: reverse of N-A.Results: In the bilateral posterior temporal areas, a negative component was evoked by all conditions in younger children (7-10 years old), older children (11-14 years old), and adults (23-33 years old) within 150-300 ms. Peak latency was significantly shorter and amplitude was significantly smaller in adults than younger and older children. Moreover, maximum amplitude was significantly larger for N-H and N-A than H-N and A-N in younger children and for N-H than the other three conditions in adults.Conclusion: The areas of the brain involved in perceiving changes in facial emotion have not matured by 14 years of age.Significance: Our study is the first to clarify a difference between children and adults in the perception of facial emotional change.
