In a pioneer import of Signal Detection Theory to this realm, threat was found to diminish the psychological distance (d') between the ink colors, but it did not impact response bias (β). The results indicate that the ESE derives from a deep perceptual change engendered by the negative stimuli and not from changes in the criterion for responding.
