Previous studies have examined the neural correlates of receiving negative feedback from peers during virtual social interaction in young people. However, there is a lack of studies applying platforms adolescents use in daily life. In the present study, 92 late-adolescent participants performed a task that involved receiving positive and negative feedback to their opinions from peers in a Facebook-like platform, while brain activity was measured using functional magnetic resonance imaging (fMRI). Peer feedback was shown to activate clusters in the ventrolateral prefrontal cortex (VLPFC), medial prefrontal cortex (MPFC), superior temporal gyrus and sulcus (STG/STS), and occipital cortex (OC). Negative feedback was related to greater activity in the VLPFC, MPFC, and anterior insula than positive feedback, replicating previous findings on peer feedback and social rejection. Real-life habits of social media use did not correlate with brain responses to negative feedback.
以往的研究探讨了年轻人在虚拟社交互动中收到同伴负面反馈时的神经关联。然而，缺乏使用青少年日常生活中所使用平台的研究。在本研究中，92名青少年晚期参与者在一个类似脸书的平台上完成了一项任务，该任务涉及从同伴那里收到对自己观点的正面和负面反馈，同时使用功能磁共振成像（fMRI）测量大脑活动。结果显示，同伴反馈激活了腹外侧前额叶皮层（VLPFC）、内侧前额叶皮层（MPFC）、颞上回和颞上沟（STG/STS）以及枕叶皮层（OC）中的多个脑区。与正面反馈相比，负面反馈与VLPFC、MPFC和前脑岛中更强的活动相关，这重复了先前关于同伴反馈和社会排斥的研究结果。社交媒体使用的现实生活习惯与大脑对负面反馈的反应无关。
