家庭援助是多种文化和背景下青少年家庭关系的一个重要方面。帮助家庭成员的动机可能是由文化因素和早期家庭经历驱动的。在这里，我们使用功能性磁共振成像来检查（1）白人和拉丁裔青少年在在线家庭援助经历中神经奖励活动的文化差异，以及（2）先前的家庭经历与帮助家庭时的神经奖励活动之间的关系。当参与者做出为家人和自己捐款的决定时，他们会被扫描。拉丁裔和白人参与者表现出相似的帮助行为水平，但中脑边缘奖励系统内的神经活动模式不同。拉丁裔参与者在为家庭做出贡献时表现出更多的奖励活动，而白人参与者在为自己赚取现金时表现出更多的奖励活动。此外，那些对家人更加认同以及在扫描前两年通过帮助家人获得更大成就感的参与者在为家人做出贡献时表现出更高的奖励系统激活程度。这些结果表明，家庭援助可能部分取决于个人从援助中获得的个人奖励，并且这种奖励感可能受到文化影响和先前家庭经历的调节。
Family assistance is an important aspect of family relationships for adolescents across many cultures and contexts. Motivations to help family members may be driven by both cultural factors and early family experiences. Here, we used functional magnetic resonance imaging to examine (1) cultural differences in neural reward activity among White and Latino youth during online experiences of family assistance and (2) how prior family experiences related to neural reward activity when helping the family. Participants were scanned as they made decisions to contribute money to their family and themselves. Latino and White participants showed similar behavioral levels of helping but distinct patterns of neural activity within the mesolimbic reward system. Whereas Latino participants showed more reward activity when contributing to their family, White participants showed more reward activity when gaining cash for themselves. In addition, participants who felt more identified with their family and who derived greater fulfillment from helping their family two years prior to the scan showed increased reward system activation when contributing to their family. These results suggest that family assistance may be guided, in part, by the personal rewards one attains from that assistance, and that this sense of reward may be modulated by cultural influences and prior family experiences.
