Results for both psychophysiological (standardized startle EMG) and behavioral indices (risk ratings [1= no risk, 2 = some risk, 3 = high risk], reaction times [ms]) of conditioned fear generalization. Error bars reflect the standard error of the mean. CS+ = conditioned stimulus paired with shock; CS- = conditioned stimulus unpaired with shock; C1, C2, C3, and C4 = generalization stimulus Classes 1, 2, 3, and 4; ITI = inter-trial-interval.
