我们开发了一个生态有效的虚拟同伴互动范式聊天室互动任务，其中60个前青少年和青少年（9-17岁）被引导相信他们正在与其他青少年在一个模拟的互联网聊天室。青少年接受虚拟同龄人的拒绝和接受反馈。研究结果显示，与接受试验相比，拒绝试验的瞳孔扩大程度更大，这是大脑认知和情感处理区域活动增加的一个指数。来自手机生态瞬时评估（EMA）协议完成后的任务的数据表明，增加瞳孔反应性排斥试验与较低的社会联系的感觉与同龄人在日常生活中。眼动分析显示，注意偏向接受反馈，远离拒绝反馈。对接受反馈的偏见更强的年龄较大的青年。避免拒绝反馈是最强的青年与增加瞳孔反应拒绝，甚至在秒导致和拒绝反馈。这些研究结果表明，青少年对拒绝反馈很敏感，并试图预测和避免参加拒绝刺激。此外，社会拒绝和接受反馈的显着性似乎在青春期增加。
We developed an ecologically valid virtual peer interaction paradigm-the Chatroom Interact Task in which 60 pre-adolescents and adolescents (ages 9-17 years) were led to believe that they were interacting with other youth in a simulated internet chatroom. Youth received rejection and acceptance feedback from virtual peers. Findings revealed increased pupil dilation, an index of increased activity in cognitive and affective processing regions of the brain, to rejection compared to acceptance trials, which was greater for older youth. Data from a cell-phone Ecological Momentary Assessment (EMA) protocol completed following the task indicated that increased pupillary reactivity to rejection trials was associated with lower feelings of social connectedness with peers in daily life. Eyetracking analyses revealed attentional biases toward acceptance feedback and away from rejection feedback. Biases toward acceptance feedback were stronger for older youth. Avoidance of rejection feedback was strongest among youth with increased pupillary reactivity to rejection, even in the seconds leading up to and following rejection feedback. These findings suggest that adolescents are sensitive to rejection feedback and seek to anticipate and avoid attending to rejection stimuli. Furthermore, the salience of social rejection and acceptance feedback appears to increase during adolescence.
