This study examined the development of prosocial charity donations and neural activity in the ventral striatum when gaining rewards for self and for charity. Participants 10-22 years (95% European heritage) participated in three annual behavioral-fMRI waves (T1: n = 160, T2: n = 167, T3: n = 175). Behaviorally, donations to charity as measured with an economic Dictator Game increased with age. Perspective taking also increased with age. In contrast, self-gain and charity-gain enjoyment decreased with age. Ventral striatum activity was higher for rewards for self than for charity, but this difference decreased during adolescence. Latent growth curve models revealed that higher donations were associated with a smaller difference between ventral striatum activation for self and charity. These findings show longitudinal brain-donations associations in adolescence.
这项研究考察了在为自己和慈善机构获得奖励时，亲社会慈善捐赠的发展和腹侧纹状体的神经活动。参与者年龄在 10-22 岁之间（95%为欧洲血统），参与了三个年度行为 fMRI 波（T1：n=160，T2：n=167，T3：n=175）。行为上，通过经济独裁游戏衡量的慈善捐赠随着年龄的增长而增加。换位思考也随着年龄的增长而增加。相比之下，自我收益和慈善收益的享受随着年龄的增长而减少。腹侧纹状体的活动对于自我奖励比慈善奖励更高，但这种差异在青春期期间减少。潜在增长曲线模型显示，较高的捐赠与腹侧纹状体对自我和慈善的激活差异较小有关。这些发现显示了青少年时期大脑捐赠的纵向关联。
