Efficient recognition of threat enhances an organism’s chances for survival. While many models of emotion posit that all negative stimuli are threatening and aversive, our research shows that human observers are keenly sensitive to various types of negative stimuli and react to them quite differently. Specifically, humans rapidly extract the spatial and temporal qualities of threat from images to decide whether danger is imminent and whether it is directed at them or someone else. I will describe the behavioral response patterns, neural substrates and dynamics, and discuss how the major visual pathways contribute to threat perception. Lastly, I will talk about how compound threat cues are extracted from faces, the underlying neural dynamics, and the modulation of these processes by anxiety differences.
