To avoid costly situations, individuals must be able to rapidly predict future adversity based on previously learnt aversive associations, as well as actively sampled information from the environment. This is compatible with the view that these changes serve to sample information in a way that allows discriminating between safe and adverse for a better threat prediction. Our results provide evidence for adaptive changes in viewing strategies of faces following aversive learning. This effect was mainly located within the eye region of faces. Aversive learning changed scanning patterns selectively along the adversity-related dimension, but not the orthogonal dimension. This introduced an adversity gradient along one specific dimension, while the other, unspecific dimension was defined solely by perceptual similarity. During learning, one face was conditioned to predict a harmful event, whereas the most dissimilar face stayed neutral. We studied how visual information was sampled by eye-movements during this process called fear generalization, using faces organized along a circular two-dimensional perceptual continuum. Animals can effortlessly adapt their behavior by generalizing from past aversive experiences, allowing to avoid harm in novel situations.
