本研究以40名8-13岁健康儿童为被试，采用厌恶性条件反射范式，考察了儿童恐惧学习和泛化的发展变化。在这个任务中，条件刺激（CS+/CS-）是两张中性的女性面孔，非条件刺激是一张恐惧的尖叫面孔。研究的第二阶段还包括一个泛化刺激（GS）：50%的CS+/-面孔混合。利用眨眼惊吓反射测量防御反应。恐惧学习和泛化的模式是合格的儿童年龄。年龄较大的儿童表现出更大的恐惧学习（即，CS+比CS-更大的惊吓）比年幼的孩子。此外，年龄较大的儿童表现出在成人中观察到的典型泛化模式，而年龄较小的儿童则没有。最后，恐惧学习也与应急意识有关;只有正确识别CS+的儿童才表现出对CS+的恐惧增强惊吓。临床意义和未来的方向进行了讨论。
The current study examined developmental changes in fear learning and generalization in 40 healthy 8–13 year-olds using an aversive conditioning paradigm adapted from. In this task, the conditioned stimuli (CS+/CS−) are two neutral female faces, and the unconditioned stimulus is a fearful, screaming face. The second phase of the study also included a generalization stimulus (GS): a 50% blend of the CS+/− faces. The eye-blink startle reflex was utilized to measure defensive responding. Patterns of fear learning and generalization were qualified by child age. Older children demonstrated greater fear learning (i.e., larger startle during CS+ than CS−) than younger children. In addition, older children exhibited the typical pattern of generalization observed in adults, whereas younger children did not. Finally, fear learning also related to contingency awareness; only children who correctly identified the CS+ demonstrated fear-potentiated startle to the CS+. Clinical implications and future directions are discussed.
