The Neural Mechanism Of Pleasure At Another's Misfortune

There not may be a pleasant emotion but sympathy or pity becaused when people suffering form some unfortunate things. This is the Schadenfreude as we say, it also be called pleasure at anothers' misfortunes.At present we do the experiments about the Schadenfreude in behavioral way. The emotion is high-level cognition and which hides Usually.By the ERP way,we can detect the real idea of different scenarios with people.And also can learn more about the psychological mechanism of schadenfreude by it.This research used three experiments. Experiment one,one people paly the Black jack by himself,we test the time when the Opponent's counts bigger than twenty one. Opponent explodes is an unfortunate incident,but people often feel happy.It's does not have the reason.this is the Schadenfreude in this reaserch. By analysis the explodes and not explodes of opponent we find they are significant difference.The results show that: the explodes than not explodes of the ERP waveforms evoked a more P200,maybe relfects the schadenfreude emotion.In experiment two, in order to know more about Schadenfreude and P200,we let one person to be the parterner of the two people who paly the black jack derectly.the person not included the competition both. In both conditions, one is explodes of opponent and the other is not explodes of opponent. Although the scenes are explodes of opponent,but the one who watch the game have two different feellings. From this we see that in both conditions, subjects experienced two different emotions. While the role of biased subjects induced ERP amplitude than those with emotional bias subjects volatility greater; P200 opponent explosion-do not burst difference wave significantly, the teammates burst-no explosion difference wave was not significant, but ((hand blast -do not burst)-(teammates burst-not explosive)) test P200 time window is still significantly different.The behavior results show that:in the explodes of opponent people feel happy was naerly 90%,in the not explodes of opponent people feel sorry was just above 8.14%,but in the explodes of partner peole feel happy was just 1.56%,but in the not explodes of parter people feel sorry was above 80.68%.All the people are so different with pooonent and parterner.The results show that too:the explodes than not explodes of the ERP waveforms evoked a more negative ERP component (P200),maybe relfects the schadenfreude emotion.In the second experiment, the behaiver result are mostly like the experiment two. but it still show that people with more pleasure of jealous one and more sympathy of weak one when they explode., this may be because people are more willing to openly express sympathy for the weak sentiments and emotions hidden jealousy. on the ERP data,statistics showed that in each time window were not significantly different, did not find the phenomenon of brain emotional side. May be it caused by the experimental design. Research in the future will be more attention to the continuity of induced subtle emotion and intensity.We can go throuth it in the future to improve.This paper introduced the brain mechanism of history and tools of the research. And introduced in four part the risk of decision-making mechanism, and the emotion on the neural mechanisms of decision-making and moral decision-making related to the neural mechanisms can activated different brain regions. And that there is no different in right and left hemisphere brain function asymmetry with Schadenfreude emotion. Schadenfreude emotions and P200 components related to positive emotions than negative emotions evoked greater volatility. P300 has nothing to do with the potency of stimulation.
