Potentiation of fear-related defense behaviours coordinated by the amygdala in response to environmental threat characterizes several anxiety disorders. We compared eye-blink startle responses to startle probes delivered during the presentation of emotional and neutral social cues in high and low generalized social anxiety. Socially anxious individuals exhibited larger startle responses to emotional (positive and negative) relative to neutral social cues, compared to non-anxious individuals.
