This research is focused on showing the physiological reactivity of the Romanian young exposed on short-terra to aggressive and TV news involving blood. The method: The participants were 73 students from the Faculty of Psychology and Educational Sciences, University of Bucharest aged between 18 and 23 (m=20.4, S.D.=1.3), 32 males and 41 females. The instruments were the followings: 1) The Laffayette Polygraph, LX 4000-Platinum Series; 2) The video stimuli recorded from Romanian TV news from the highest rated TV broadcasting news, scheduled at 17.00 and 19.00 hours (during the afternoon). The results: By applying Wilcoxon nonparametric test for dependent experimental groups, the hypotheses regarding the statistically significant differences between the GSR (p < 0.05) and the blood pressure (p < 0.05) during the exposure to TV news involving blood and aggression have been confirmed. The findings provide evidence to parents and teachers who should prohibit their children from watching TV news involving blood and aggression and replace them with educational, cultural or other kind of TV news.
