The BDNF Val66Met polymorphism impacts victim's moral emotions following interpersonal transgression

Immoral behaviors make individuals abominate and punish transgressors. Inspired by the associations between the Val66Met polymorphism of brain‐derived neurotropic factor (BDNF) gene and emotional responses following negative events, we investigated whether this polymorphism was also associated moral emotions such as punishment and forgiveness following interpersonal transgression. To do so, we categorized 340 individuals according to the BDNF Val66Met and assessed moral emotions by using 12 hypothetic scenarios in different conditions of intention and interpersonal consequence. The results indicated that this polymorphism was significantly associated with moral aversion and punishment towards transgressors. Victims with the Val/Val genotype expressed less aversion and punishment than the Met carriers, regardless of intention and interpersonal consequence. Moreover, this polymorphism was associated with forgiveness. Victims with the Val/Val genotype expressed more forgiveness than the Met carriers. Taken together, these findings highlight the importance of the BDNF Val66Met to moral emotions.     

母亲的情景特异性归因与儿童问题行为:儿童消极情绪的调节作用

以67对3~6岁的儿童及其母亲为研究对象,通过假设情景法探索母亲对不同情景下儿童问题行为的归因方式,并考察这种特定情景下的归因对儿童后续问题行为的影响,以及儿童消极情绪的调节作用。研究发现:(1)母亲对儿童不同问题行为的稳定性归因和不可控归因存在情景上的差异;(2)母亲的不可控归因和稳定性归因可以影响儿童内隐问题行为的发展且受到儿童消极情绪的影响,但母亲的归因方式不可以预测儿童的外显问题行为。
