Evidence increasingly suggests that neural structures that respond to primary and secondary rewards are also implicated in the processing of social rewards. The 'Like'-a popular feature on social media-shares features with both monetary and social rewards as a means of feedback that shapes reinforcement learning. Despite the ubiquity of the Like, little is known about the neural correlates of providing this feedback to others. In this study, we mapped the neural correlates of providing Likes to others on social media. Fifty-eight adolescents and young adults completed a task in the MRI scanner designed to mimic the social photo-sharing app Instagram. We examined neural responses when participants provided positive feedback to others. The experience of providing Likes to others on social media related to activation in brain circuity implicated in reward, including the striatum and ventral tegmental area, regions also implicated in the experience of receiving Likes from others. Providing Likes was also associated with activation in brain regions involved in salience processing and executive function. We discuss the implications of these findings for our understanding of the neural processing of social rewards, as well as the neural processes underlying social media use.
越来越多的证据表明，对初级和次级奖励做出反应的神经结构也与社会奖励的处理有关。“点赞”是社交媒体上的一个流行功能，它具有货币和社会奖励的共同特征，是一种塑造强化学习的反馈方式。尽管“点赞”无处不在，但人们对给予他人这种反馈的神经相关性知之甚少。在这项研究中，我们绘制了在社交媒体上给他人点赞的神经相关性图谱。58 名青少年和年轻人在磁共振成像扫描仪中完成了一项旨在模拟社交媒体照片分享应用程序 Instagram 的任务。当参与者给他人提供积极的反馈时，我们检查了他们的神经反应。在社交媒体上给他人点赞的体验与包括纹状体和腹侧被盖区在内的奖励回路中的神经活动有关，这些区域也与他人点赞的体验有关。点赞还与参与突显处理和执行功能的大脑区域的激活有关。我们讨论了这些发现对我们理解社会奖励的神经处理以及社交媒体使用背后的神经过程的意义。
