健康风险认知过程中的信息框架效应及其神经活动特征分析

Information Framing Effect and the Characteristics Analysis of Neural Activity from the Process of Health Risk Cognition

【目的/意义】探讨特定健康风险认知中的信息框架效应及其神经活动特征,深入了解用户认知层面的信息呈现方式偏好,对提高信息服务效果、促进智能化推荐服务非常重要。【方法/过程】以大学生熬夜现象为研究情境设计实验,采用脑电信号采集和分析信息的目标框架效应和神经活动特征,结合自我报告式问卷调查方法,对数据结果相互验证。【结果/结论】脑电数据和行为数据两种研究路径均显示熬夜相关健康风险信息存在框架效应,且正性框架信息的刺激对受试者的效果相对较明显。认知神经科学方法获得的生理数据分析与传统问卷自我报告数据分析相互印证,表明结果具有稳定性和科学性。【创新/局限】通过脑电和行为两个层面的实验方法揭示了熬夜风险信息的框架效应和认知过程的个体脑电神经状态,进一步丰富了用户健康风险认知过程中的信息交互理论;但本文的结论对于其他健康风险认知领域问题是否具有普遍的适用性还需要进一步的探究。

【Purpose/significance】To explore the information framing effect and its neural activity characteristics in the cognition of specific health risks,deeply understanding the preferences of information presentation at the user’s cognitive level is highly important to improve the effectiveness of information services and promote intelligent recommendation services.【Method/process】The experiment was designed by taking the phenomenon of college students staying up late as the research situation,the target framing effect and neural activity characteristics of EEG signals were collected and analyzed,and the data results were verified by self-report questionnaire method.【Result/conclusion】Both EEG data and behavioral data show that there is a framing effect on health risk information related to staying up late,and the stimulus of positive framing information has a relatively obvious effect on subjects.The analysis of physiological data obtained by cognitive neuroscience method and the analysis of traditional questionnaire self-report data are confirming with each other,indicated that the results are stable and scientific.【Innovation/limitation】The framing effects of staying up late risk information and the individual EEG neural state of the cognitive process are revealed through the experimental methods at the EEG and behavioral levels,which further enriches the information interaction theory in the user’s health risk cognition process.Whether other health risk perception issues have general applicability requires further exploration.However,whether the conclusion of this article has universal applicability for other problems in the field of health risks cognition need further exploration.
