Fear-learning through observing others begins early in life. Yet, most observational fear-learning research has focused on adults. The current study used a novel developmentally appropriate observational fear conditioning paradigm to examine differences in observational fear-learning among children, adolescents, and adults.
Thirty-six typically developing children, 41 typically developing adolescents, and 40 adults underwent differential observational fear conditioning followed by a direct exposure test. Skin conductance response (SCR) and self-reported fear were measured.
Successful differential observational fear-learning was demonstrated in all three age groups as indexed by SCR, yet developmental differences emerged. Children showed overall higher physiological arousal during acquisition compared to adolescents and adults. Additionally, children reported less differential fear and were less successful at reporting the conditioned stimulus-unconditioned stimulus contingency compared to adolescents and adults. Finally, adolescents tended to overgeneralize their fear compared with adults.
This is the first study to compare observational fear-learning among children, adolescents, and adults. The novel task effectively induced observational fear-learning, particularly among adolescents and adults. Findings revealed developmental differences that have both theoretical and clinical implications.
通过观察他人来学习恐惧在生命早期就开始了。然而,大多数观察性恐惧学习研究都集中在成年人身上。当前的研究使用了一种新颖的适合不同发育阶段的观察性恐惧条件范式,来检验儿童、青少年和成年人在观察性恐惧学习方面的差异。
36名发育正常的儿童、41名发育正常的青少年和40名成年人接受了差异观察性恐惧条件训练,随后进行直接暴露测试。测量了皮肤电反应(SCR)和自我报告的恐惧程度。
所有三个年龄组都通过SCR指标证明了成功的差异观察性恐惧学习,但出现了发育差异。与青少年和成年人相比,儿童在习得过程中总体上表现出更高的生理唤醒水平。此外,与青少年和成年人相比,儿童报告的差异恐惧较少,在报告条件刺激-非条件刺激的关联性方面也不太成功。最后,与成年人相比,青少年倾向于过度泛化他们的恐惧。
这是第一项比较儿童、青少年和成年人观察性恐惧学习的研究。这项新颖的任务有效地诱导了观察性恐惧学习,特别是在青少年和成年人中。研究结果揭示了具有理论和临床意义的发育差异。
