Behavior in novel situations is guided by similarities to previous experiences, a phenomenon known as generalization. Despite the widespread influence of generalization on healthy and pathological behavior, insight into the underlying mechanisms is lacking. It remains unclear whether a failure to notice situational changes contributes to the generalization of learned behavior. We combined a fear conditioning and generalization procedure with a perceptual decision task in humans and found that a failure to perceive a novel stimulus as different from the initial fear-evoking stimulus was associated with increased conditioned responding. These findings demonstrate the potential of a perception-centered approach to better understand (pathological) behavior and its underlying mechanism and are a promising avenue for the development of refined generalization protocols.
在新情境中的行为受先前经验相似性的指导，这一现象被称为泛化。尽管泛化对健康和病态行为有着广泛的影响，但对其潜在机制仍缺乏了解。目前尚不清楚未能注意到情境变化是否会导致所学行为的泛化。我们在人类中结合了恐惧条件反射和泛化程序与知觉决策任务，发现未能将新刺激感知为与最初引起恐惧的刺激不同与增强的条件反应有关。这些发现表明，一种以感知为中心的方法具有潜在的优势，可以更好地理解（病态）行为及其潜在机制，并且是开发更精细的泛化协议的有前途的途径。
