People often behave differently when they know they are being watched. Here, we report the first investigation of whether such social presence effects also include brain monitoring technology, and also their impacts on the measured neural activity. We demonstrate that merely informing participants that fMRI has the potential to observe (thought-related) brain activity is sufficient to trigger changes in functional connectivity within and between relevant brain networks that have been previously associated selectively with executive and attentional control as well as self-relevant processing, social cognition, and theory of mind. These results demonstrate that an implied social presence, mediated here by recording brain activity with fMRI, can alter brain functional connectivity. These data provide a new manipulation of social attention, as well as shining light on a methodological hazard for researchers using equipment to monitor brain activity.

记录大脑活动可以充当隐含的社会存在并改变神经连接性。

人们知道自己受到监视时，通常会表现出不同的行为。在这里，我们报告了有关这种社会存在效应是否还包括大脑监测技术及其对测得的神经活动的影响的首次调查。我们证明，仅告知参与者功能磁共振成像有潜力观察（与思想相关的）大脑活动就足以触发相关大脑网络内部和之间的功能连接性变化，这些功能先前已选择性地与执行和注意力控制以及自我控制相关联。相关处理，社会认知和心理理论。这些结果表明，通过功能磁共振成像记录大脑活动介导的隐含社交存在可以改变大脑功能连接。这些数据提供了一种新的社会关注手段，
