Figure 3: Average standardized startle EMG magnitudes during the generalization test by group (high and low Threat Estimation), 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 and class 4 (C4) than for the safety cue in the high Threat Estimation group, but were only larger for the danger cue in the low Threat Estimation group.
