Figure 2: Average standardized startle EMG magnitudes during the generalization test by group (high and low Obsessive-compulsive Inventory- Revised), for the inter-trial interval (ITI), safety cue (CS–), four classes of generalization stimuli (C1, C2, C3, C4), and danger cue (CS+). Black dots indicate that the startle EMG magnitudes were significantly larger for the danger cue than for the safety cue.
