Perceptual or conceptual? Modulation of fear generalization pathways by prior learning experience

摘要: 过度的恐惧泛化是各类焦虑症的核心症状, 人类的恐惧反应既可沿刺激的知觉线索传递, 也可根据刺激的概念信息蔓延, 给患者的生活造成极大负担。本研究采用经典的差异性条件恐惧范式, 以US预期和皮肤电反应为指标, 探讨了恐惧习得前的学习经验对两种恐惧泛化路径的调节作用。本研究共招募50名在校大学生, 在恐惧习得前, 被试被随机分为两组, 一组对刺激的知觉属性进行判断学习(知觉组), 另一组则对刺激的概念属性进行判断学习(概念组), 随后两组被试进行完全相同的恐惧习得和泛化测试。结果显示, 知觉组被试产生了显著的知觉性恐惧泛化, 而概念组被试则表现出明显的概念性恐惧泛化, 先前经验显著影响了被试恐惧泛化的路径。此外, 概念组被试还表现出明显的知觉性恐惧泛化的倾向, 而知觉组却未发现任何概念性恐惧泛化的迹象, 两组被试在恐惧泛化路径上表现出非对称的特点。

摘要: 过度的恐惧泛化是各类焦虑症的核心症状, 人类的恐惧反应既可沿刺激的知觉线索传递, 也可根据刺激的概念信息蔓延, 给患者的生活造成极大负担。本研究采用经典的差异性条件恐惧范式, 以US预期和皮肤电反应为指标, 探讨了恐惧习得前的学习经验对两种恐惧泛化路径的调节作用。本研究共招募50名在校大学生, 在恐惧习得前, 被试被随机分为两组, 一组对刺激的知觉属性进行判断学习(知觉组), 另一组则对刺激的概念属性进行判断学习(概念组), 随后两组被试进行完全相同的恐惧习得和泛化测试。结果显示, 知觉组被试产生了显著的知觉性恐惧泛化, 而概念组被试则表现出明显的概念性恐惧泛化, 先前经验显著影响了被试恐惧泛化的路径。此外, 概念组被试还表现出明显的知觉性恐惧泛化的倾向, 而知觉组却未发现任何概念性恐惧泛化的迹象, 两组被试在恐惧泛化路径上表现出非对称的特点。
