Anxiety ratings and startle during the no-shock, predictable-shock, unpredictable-shock (NPU) threat task. (A) Anxiety ratings reported on a scale from 0 to 10. (B) Potentiated startle represented as T scores. For both measures, difference scores were calculated to correspond to fear (fear-potentiated startle [FPS]: predictable cue − predictable intertrial interval [iti]), anxiety during the ITI (APS_ITI: unpredictable ITI − neutral ITI), and anxiety during the cue (APS_cue: unpredictable cue − neutral cue). Bars represent the mean ± SEM. ∗p < .05.
