我们测试的假设，概念相似性促进条件恐惧的泛化。使用感官预处理程序，三组受试者学习了两个线索之间的关联，这两个线索在概念上是相似的，不相关的，或不匹配的。接下来，其中一个提示与电击配对。另一个线索，然后重新引入测试恐惧泛化，通过皮肤电导反应测量。结果表明，增强恐惧泛化与特质焦虑水平的一组，学习概念相似的刺激之间的关联。这些发现表明，条件刺激的概念表征影响人类的恐惧学习过程。
We tested the hypothesis that conceptual similarity promotes generalization of conditioned fear. Using a sensory preconditioning procedure, three groups of subjects learned an association between two cues that were conceptually similar, unrelated, or mismatched. Next, one of the cues was paired with a shock. The other cue was then reintroduced to test for fear generalization, as measured by the skin conductance response. Results showed enhanced fear generalization that correlated with trait anxiety levels in the group that learned an association between conceptually similar stimuli. These findings suggest that conceptual representations of conditional stimuli influence human fear learning processes.
