损失厌恶与偏好异质性--来自神经经济学的证据

Loss Aversion and Preference Heterogeneity

损失厌恶是行为经济学家发现的人类进行风险决策时的一种重要行为模式。我们通过近年来兴起的功能性近红外脑成像(fNIRS)技术,对被试风险决策时的大脑前额叶皮层进行了测量和成像。结果表明,人们在处理收益和损失时,大脑皮层的激活状态存在着明显的差异。由此可以证实,损失厌恶是一种人类在长期进化过程中所获得的适应性心理本能。

Behavioural economists found that loss aversion is an important behavior patterns when human in risk decision - making. We through in recent years the rise of functional near infrared imaging （fNIRS）, tested the the prefrontal cortex when people in risk decision -making. The results show that when people dispose gains or losses, the cerebral cortex activation state there are obvious differences. To confirm that loss aversion is a adaptability psychological instinct and the product of human long -term evolution.
