信息共享影响着信息的传播,塑造着人们的信仰、行为和文化。在美国和荷兰进行的一项预先注册的神经影像学研究中,我们证明了基于大脑的信息共享预测模型的可复制性、预测有效性和可推广性。重复Scholz等人的发现,Proc. Natl. Acad. Sci. U.S.A. 114,2881-2886(2017),一组个体中与自我、社会和价值观相关的神经信号跟踪了美国新闻文章的人群共享。在Scholz et al.(2017)数据上训练的预先注册的基于大脑的预测模型被证明可推广到新数据,比单独的自我报告评级解释了更多的人口共享差异。神经信号(与自我报告相比)更可靠地预测跨文化的分享,这表明它们捕获了分享行为背后更普遍的心理机制。这些发现强调了分享的关键神经认知基础,提出了提高信息有效性的干预措施的潜在目标机制,并推进了大脑预测研究。
Information sharing influences which messages spread and shape beliefs, behavior, and culture. In a preregistered neuroimaging study conducted in the United States and the Netherlands, we demonstrate replicability, predictive validity, and generalizability of a brain-based prediction model of information sharing. Replicating findings in Scholz et al., Proc. Natl. Acad. Sci. U.S.A. 114, 2881–2886 (2017), self-, social-, and value-related neural signals in a group of individuals tracked the population sharing of US news articles. Preregistered brain-based prediction models trained on Scholz et al. (2017) data proved generalizable to the new data, explaining more variance in population sharing than self-report ratings alone. Neural signals (versus self-reports) more reliably predicted sharing cross-culturally, suggesting that they capture more universal psychological mechanisms underlying sharing behavior. These findings highlight key neurocognitive foundations of sharing, suggest potential target mechanisms for interventions to increase message effectiveness, and advance brain-as-predictor research.
