A sinner should be what kind of punishment? It is fire, whipped hung up? Or exile? A new study found that the brain several brain regions in the brain ideological struggle finally decided to moderate the severity of a person guilty of punishment.
Often people need timely and severe penalties to regulate their own behavior, especially the injury or offense to others describe some terrible details of the crime the person to others. However, certain areas of the brain can be the case no matter how much more shocking event, by intuition to predict something unintentional injury.
Scientists experiment to understand how the brain under some reasonable conclusions, experiments involving 30 participants. Researchers showed them a series of one who caused harm to another scene, endangering four levels: death, disability, physical assault and property damage. Half of these scenes is recognized as intentional harm volunteers, and the other half were deemed unintentional. Look at the picture of the volunteers, their brain images using functional magnetic resonance imaging (fMRI) technology to shoot down, in order to determine when their judgment of what is in the active brain areas.
A scene of image interpretation is: "Steve suddenly fell onto the rocks, heavy impact almost every bone in his body is broken by screams kept his mouth diffuse out Xuemo swallow too vague, and finally loss of blood. too much death. "scientists have found that, like such a horrible death than of a lack of emotional descriptive words make it easier for volunteer offenders require more severe punishment, but then there is also a severe degree.
Study participants, a postdoctoral fellow at Harvard Medical School in Boston Michael Treadway said: "This is our misguided volunteers for this death was deliberate to be useful, when the event was an accident regardless of language when more suggestive and provocative degree they will not cause such a reaction. "that is, in this example just the climbing, if Steve is that he did not grasp the rope out of an accident, rather than a result of companion untied the rope, not volunteers considers companions need to be penalties.
Brain imaging data of volunteers showed that when death was identified as intentional, brain regions associated with emotion evoking such as the amygdala will follow the graphic language interpretation was provoked active, but also mood-related brain regions and dorsolateral prefrontal cortex (in deciding what punishment is essential to make) a stronger link. And when death was unintentional, Treadway said: "The amygdala does not react image language, other brain regions seem to be adjusted."
Temporal gyrus that is suppressed beginning amygdala emotional impulses brain regions, preventing the emotional impact on people's decisions. Professor of psychology at Vanderbilt University Ren Marois said: "The results obtained are essentially reassuring, a fundamental aspect of the human experience is to penalize harmful behavior, even if you did not know the victim is the same person. the discovery is important when we realize that the harm is caused unintentionally, the impulse to punish the defendant will brake in time. "
Researchers wrote in the report: This emotional impulses need to be "regulatory network" control, rather than simply from one brain region to brain brakes. This study not only refers to the social impact of the crime, also relates to the settlement of the conflict of social interaction.
The scientists say their results are not across cultures and time can not pretend to say that some of the theory associated, because in many parts of the world, people will impose severe punishment seemingly trivial offenses, such as stealing from hungry people block bread must cut hand. Treadway speculate on whether the perception of guilt and the severity of a scene should have a relationship with culture.
