Trust plays an important role during adolescence for developing social relations. While prior developmental studies give us insight into adolescents’ development of differentiation between close (e.g., friends) and unknown (e.g., unknown peers) targets in trust choices, less is known about the development of trust to societal targets (e.g., members of a community organization), and its underlying neural mechanisms. Using a modified version of the Trust Game, our preregistered fMRI study examined the underlying neural mechanisms of trust to close (friend), societal (community member), and unknown others (unknown peer) during adolescence in 106 participants (aged 12-23). Adolescents showed most trust to friends, less trust to community members, and the least trust to unknown peers. Neural results show that target differentiation in adolescents’ trust behavior is associated with activity in social brain regions implicated during mentalizing, reward processing, and cognitive control. Recruitment of the medial prefrontal cortex (mPFC) and orbitofrontal cortex was higher for closer targets (i.e., friend and community member). For the mPFC, this effect was most pronounced during no trust choices. Trust to friends was additionally associated with increased activity in the precuneus and bilateral temporal parietal junction. In contrast, bilateral dorsolateral prefrontal cortex and anterior cingulate cortex were most active for trust to unknown peers. The mPFC showed increased activity with age and consistent relations with individual differences in feeling needed/useful.

本数据集包含了 Sweijen 等人（2023）所著《青少年对朋友、社区成员及陌生同侪信任的神经机制》一文中处理后的数据。信任在青少年时期社会关系的构建中扮演着至关重要的角色。尽管先前的发展研究为我们揭示了青少年在信任选择中对亲近目标（如朋友）与陌生目标（如陌生同侪）之间差异化的形成过程，但对于对社会责任目标（如社区组织成员）的信任发展及其潜在的神经机制，了解尚显不足。本研究采用改良版的信任游戏，通过预注册的fMRI研究，对106名参与者（年龄在12至23岁之间）在青少年时期对亲近他人（朋友）、社会他人（社区成员）及陌生他人（陌生同侪）的信任的潜在神经机制进行了考察。结果显示，青少年对朋友的信任度最高，对社区成员的信任度次之，而对陌生同侪的信任度最低。神经学结果揭示了青少年在信任行为中的目标差异化与心智化、奖励处理和认知控制期间涉及的社会脑区活动相关联。内侧前额叶皮层（mPFC）和眶额叶皮层在亲近目标（即朋友和社区成员）的招募中表现出较高的活动水平。对于mPFC而言，这种效应在无信任选择期间最为显著。对朋友的信任还与顶叶联合区及双侧颞顶联合区活动增加有关。相反，双侧背外侧前额叶皮层和前扣带皮层在信任陌生同侪时最为活跃。mPFC的活动随年龄增长而增加，并与个体感知到被需要或有用的差异保持一致。本出版物包中包含处理后的数据文件。文件可供研究作者访问。有兴趣的各方可以通过发送电子邮件至 [e-mail] 请求访问。在请求数据时，请说明您希望访问文件的原因。
