Examined the nature of the physiological relationship between discloser and listener. Skin conductance level (SCL) and heart rate were recorded while 63 undergraduates (aged 17-30 yrs) watched a 1-2 hr videotaped interview of 1 of 33 Holocaust survivors disclosing their World War II experiences. The simultaneous physiological measurements of the Holocaust disclosers and Ss were averaged into 1-min blocks and correlated with each other. Of the significant SCL correlations between the disclosers and listeners, 70% were from listeners who evidenced SCL patterns that fluctuated in an inverse pattern to the disclosers. Those listeners who evidenced SCL patterns corresponding to the disclosers were more likely to have high scores on a feelings inventory and report experiencing similar emotions as the disclosers. Results suggest a fundamental distinction between disclosing traumatic experiences and listening to them.
