Abstract

Online sharing impacts which information is widely available and influential in society. Yet, systematically influencing sharing behavior remains difficult. Past research highlights two factors associated with sharing: the social and self-relevance of the to-be-shared content. Based on this prior neuroimaging work and theory, we developed a manipulation in the form of short prompts that are attached to media content (here health news articles). These prompts encourage readers to think about how sharing the content may help them to fulfill motivations to present themselves positively (self-relevance) or connect positively to others (social relevance). Fifty-three young adults completed this pre-registered experiment while undergoing functional magnetic resonance imaging. Ninety-six health news articles were randomly assigned to three within-subject conditions that encouraged self-related or social thinking or a control. Invoking self-related or social thoughts about health-related news (vs control) (i) causally increased brain activity in a priori regions of interest chosen for their roles in processing social and self-relevance and (ii) causally impacted self-reported sharing intentions. This study provides evidence corroborating prior reverse inferences regarding the neural correlates of sharing. It further highlights the feasibility and utility of targeting neuropsychological processes to systematically facilitate online information spread.

调用自我相关和社会思想影响在线信息共享。

在线分享影响着哪些信息可以广泛获得，并对社会产生影响。然而，系统地影响分享行为仍然很困难。过去的研究强调了与分享相关的两个因素:被分享内容的社交性和自我相关性。基于先前的神经成像工作和理论，我们开发了一种附加在媒体内容(这里是健康新闻文章)上的简短提示形式的操作。这些提示鼓励读者思考分享内容如何帮助他们实现积极地展示自己(自我相关性)或积极地与他人联系(社会相关性)的动机。53名年轻人在接受功能性磁共振成像的同时完成了这个预先注册的实验。96篇健康新闻文章被随机分配到三个鼓励自我相关思维或社会思维或对照的主题条件下。唤起与健康相关的新闻有关的自我相关或社会的想法(与对照相比)(i)会导致大脑在处理社会和自我相关的过程中所选择的先验感兴趣区域的活动增加，(ii)会导致自我报告的分享意图受到影响。本研究提供了证据，证实了先前关于分享的神经相关性的反向推断。它进一步强调了针对神经心理过程系统地促进在线信息传播的可行性和实用性。

期刊介绍： SCAN will consider research that uses neuroimaging (fMRI, MRI, PET, EEG, MEG), neuropsychological patient studies, animal lesion studies, single-cell recording, pharmacological perturbation, and transcranial magnetic stimulation. SCAN will also consider submissions that examine the mediational role of neural processes in linking social phenomena to physiological, neuroendocrine, immunological, developmental, and genetic processes. Additionally, SCAN will publish papers that address issues of mental and physical health as they relate to social and affective processes (e.g., autism, anxiety disorders, depression, stress, effects of child rearing) as long as cognitive neuroscience methods are used.
