青春期是社会情感敏感性增加的时期，这通常与健康风险行为的增加有关。然而，相对于低水平（社会真空）或高水平（特别协调），中等水平的社会敏感性可能会带来好处，因为它有助于有效地导航社会世界。本fMRI研究测试社会敏感性和适应性决策之间的曲线关系。参与者（12-16岁; N = 35）玩社交焦虑风险任务，该任务衡量参与者敲门以赚取积分的意愿。每敲一次，住户的表情就从高兴变成了愤怒。如果居民变得太生气，门砰的一声关上，参与者失去了积分。社会敏感性被定义为青少年根据面部表情的变化调整风险选择的程度。结果证实了曲线关系的社会敏感性和自我报告的适应性决策在行为和神经水平。适度的青少年社会敏感性调制通过提高跟踪社会线索在颞顶交界处，颞叶和背外侧前额叶皮层和相关的适应性决策。这些研究结果表明，社会情感敏感性可能会对青少年的结果产生积极影响，并对帮助青少年达到成熟的社会目标的干预措施产生影响。
Adolescence is a time of increased social-affective sensitivity, which is often related to heightened health-risk behaviors. However, moderate levels of social sensitivity, relative to either low (social vacuum) or high levels (exceptionally attuned), may confer benefits as it facilitates effective navigation of the social world. The present fMRI study tested a curvilinear relationship between social sensitivity and adaptive decision-making. Participants (ages 12–16; N = 35) played the Social Analogue Risk Task, which measures participants’ willingness to knock on doors in order to earn points. With each knock, the facial expression of the house’s resident shifted from happy to somewhat angrier. If the resident became too angry, the door slammed and participants lost points. Social sensitivity was defined as the extent to which adolescents adjusted their risky choices based on shifting facial expressions. Results confirmed a curvilinear relationship between social sensitivity and self-reported adaptive decision-making at the behavioral and neural level. Moderate adolescent social sensitivity was modulated via heightened tracking of social cues in the temporoparietal junction, insula and dorsolateral prefrontal cortex and related to adaptive decision-making. These findings suggest that social-affective sensitivity may positively impact outcomes in adolescence and have implications for interventions to help adolescents reach mature social goals into adulthood.
