Fear generalization has been identified as an important mechanism that might contribute to the etiology and maintenance of anxiety disorders. It is, however, yet unclear to what degree attentional processes contribute to overgeneralization of fear in clinical samples. To address this issue, we utilized a set of facial photographs that was meticulously created such that pairs of faces could either be distinguished by looking into the eyes or the region around mouth and nose, respectively. These pairs were then employed as CS+ and CS− in a differential fear conditioning paradigm followed by a generalization test with morphs in steps of 20%, creating a continuum between CS+ and CS−. In a sample with diverse levels of social anxiety (N = 87), we demonstrated that the amount of fear generalization depends on attentional orienting towards diagnostic facial features. While social anxiety did not affect the shape of generalization gradients, we observed elevated threat ratings, altered visual exploration patterns, and a distinct multi-phasic heart rate modulation in participants with higher social anxiety. In summary, fear generalization depends on attentional deployment. Future work should build on these findings to further explore these processes in clinical populations.
