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. 相似文献
This study aims to discuss the effect of ethnicity on child maltreatment trauma in China and to contribute to international knowledge on the quality of life of children. The data come from a survey of 1763 rural children (Mage = 12.34, 50.0% boys) in three multi-ethnic counties in western China that was conducted from November 2019 to January 2020 with the modified versions of the “Juvenile Victimization Questionnaire” Scale. There are three important findings of this study. First, child maltreatment is significantly related to child depression in China. The depression score and rate of severe depression symptoms (SDS) are 2.09 times and 3.82 times higher, respectively, for maltreated children than children without maltreatment. Second, the effects of maltreatment on child depression differ significantly among the ethnic groups. The negative effect of maltreatment is most influential among the Han population and least influential among the Zhuang population. Third, ethnic disparities are also found in the effects of the influencing factors on child depression. The effect of intergenerational relationships on child depression is significant only in the Han and Tibetan populations, while the negative effect of peer support is found only among Han, Tibetan, and Miao children. Based on the confirmation of ethnic disparities in trauma due to maltreatment, this study suggests that it is necessary to establish a high-quality psychological intervention system in China’s multi-ethnic counties.
A 52 m drop tube has been used to solidify bulk-glass-forming Zr41Ti14Cu12.5Ni10Be22.5 alloy. Glassy balls with different sizes solidified from the droplets whose structural features, glass-transition behaviour and crystallization kinetics have been investigated. The results indicate that the apparent activation energies of the glass transition and main crystallization reaction are significantly different from those of samples prepared by water quenching. The structural difference between the two types of glassy specimen is revealed by compression studies and in situ energy-dispersive X-ray diffraction. The results are important for understanding the structural features of bulk-forming glasses. 相似文献
Risk preference during decision making depends not only on the potential risk and profits but also on the roles taken in the current task. Those who perform tasks are more risk-seeking than those who only watch. Given the prominent effect of experiencing the task, the player–spectator discrepancies are supposed to arise in the experiencing phase instead of the choosing phase. In the present study, the authors separated the experiencing role and the choosing role through a stylus maze task in which participants first performed in pairs—one as the player and the other as the spectator—and then chose from two rewarding options for themselves or their partners. The findings show that the experience as players induced a risk-seeking tendency in decision making, which suggests that it was the experiencing role, rather than the choosing role, that caused the difference of risk preference, at least for financially motivated groups and under similar task conditions. 相似文献
We report a theoretical investigation on the control of wave-vector filtering (WVF) in a two-dimensional electron gas modulated by realistic magnetic barriers and δ-doping, which can be experimentally realised by depositing a ferromagnetic stripe on the surface of a GaAs/AlxGa1?xAs heterostructure and using atomic layer doping. Theoretical analysis demonstrates that a sizeable WVF effect still exists even if δ-doping is introduced into the device. Numerical calculation reveals that the WVF efficiency is related closely to the δ-doping. Thus, the WVF effect in a magnetic nanostructure can be conveniently manipulated by properly adjusting the weight and/or the position of the δ-doping, giving rise to a tunable momentum filter for nanoelectronics applications. 相似文献
