Abstract:
A hallmark symptom of fear and anxiety disorder is generalization of fear to essentially innocuous stimuli and situations. Such generalization can occur through both perceptual and conceptually similarities. Recent studies indicate that perceptual generalization is inflated in anxiety patients and individuals prone to develop anxiety disorders, suggesting that perceptual generalization may be involved in the etiology of anxiety disorders. Here, we wanted to address whether conceptual generalization is potentially implicated in the development of anxiety disorders as well. As hypothesized, we observed clear conceptual fear generalization gradients using both self-report and psychophysiological measures. However, in contrast to our expectations, these conceptual generalization gradients were not correlated with different anxious traits (i.e., trait anxiety, intolerance of uncertainty, and behavioral inhibition). Additionally, we discuss potential reasons for the absence of the expected correlations between conceptual fear generalization and anxious traits, such as restricted variability in both the generalization task and the sample. We conclude that the paradigm has promise for further research on conceptual fear generalization.
