Subjects were twenty female and nine male paid volunteers between the ages of 19 and 38. Perceptual defense, defined as the difference in recognition thresholds for unpleasant versus pleasant words, was assessed with a tachistoscopic masking paradigm. Auditory evoked potentials (AEPs) were obtained in an augmentation reduction paradigm that evaluated cortical responses to discrete tones of varying intensity. Cardiac responses to these same tones were also obtained. Amplitude/intensity slopes were determined for P2 amplitudes obtained from the …
