怎样会让我们感觉更危险——风险沟通渠道分析

How Can a Risk Be Increased?–An Analysis of Risk Communication Channels–

以实验设计与问卷测量相结合的方法，向被试提供真实的环境风险材料，探讨不同类型的（人为或自然）风险、形象性信息、不同感觉通道的信息输入（声音或文字），以及不同沟通渠道对风险认知的影响。实验一采用实验室设计，发现人为风险比自然风险引起更高的风险认知，形象性信息的呈现增加了风险认知，但不同感觉通道的信息输入对风险认知没有影响。实验二模拟现实生活中电视和网页对风险信息的传递，比较两种沟通渠道对风险认知的影响，结果表明电视比网页唤起更高的风险认知。

A risk is objective; however， its perception is subjective. This subjectivity is based on many factors (risk communication style， probability of the occurrence of risky events， etc.) with a relative stability and measurability. However， a gap exists between subjective perception and the objective risk. The psychometric paradigm proposed by Slovic is the most widely-used method to qualitatively analyze risk perception using psychometric scaling. It enables researchers to obtain dimensions that af
