由于进化意义,蛇和蜘蛛等与恐惧相关的刺激物被认为能引起人们的注意。经典的条件反射实验表明,这些刺激可以加速学习,而指令性灭绝实验表明,它们对指令的反应可能较弱。我们在指导性厌恶逆转学习期间操纵刺激类型,并使用定量模型来同时测试这两个假设。两组的皮肤电导率在接受指令后立即逆转。然而,与恐惧相关的刺激增强了动态学习,通过观察蛇和蜘蛛图像的参与者的较高学习率来衡量。结果与可分离神经通路是反馈驱动和指导性厌恶学习的基础的发现一致。
Fear-relevant stimuli such as snakes and spiders are thought to capture attention due to evolutionary significance. Classical conditioning experiments indicate that these stimuli accelerate learning, while instructed extinction experiments suggest they may be less responsive to instructions. We manipulated stimulus type during instructed aversive reversal learning and used quantitative modeling to simultaneously test both hypotheses. Skin conductance reversed immediately upon instruction in both groups. However, fear-relevant stimuli enhanced dynamic learning, as measured by higher learning rates in participants conditioned with images of snakes and spiders. Results are consistent with findings that dissociable neural pathways underlie feedback-driven and instructed aversive learning.
