关键词: 风险认知

       本研究采用多维度的任务结构和多维度的分析模型探讨风险认知问题。整体研究主要由三部分组成：1，一般社会情景下的风险认知研究：即为寻求公众一般的风险认知信息所作的探讨；2，工作情景中的风险认知研究：专门针对企业的实际情景而设计的问卷研究；3，风险认知策略的计算机模拟实验：在问卷研究基础上的2×2×3设计的实验室情景研究。
       研究获得了广泛的有关风险认知的数据，包括风险因素的风险程度，风险因素的性质，风险认知策略，初步的风险认知空间结构，以及相关的群体特征等。
       问卷均具有可接受的信度、效度指标。
       实验研究是问卷研究的深入和补充，实验研究为问卷研究建立了有效的效标行为。结果之间相互支持，互为其成立的证据。

       Abstract
       This research used a multitask,multimodel approach to probe the problem ofrisk perception.It consists of three parts.First,the research of riskperception in general social circumstances,the aim is to collect informationabout the risk perceived by popular;Secondly,which is related to the first one,the research of risk perception under working circumstances,in the form ofquestionaire on enterprises;Thirdly,an experimental test of risk cognitivestrategies by computer simulation,that is 2×2×3 design of laboratoryresearch based on questionaire.
       This research has acquired extensive and informative data on perceivedrisk,including its magnitude,nature,cognitive strategy,and the preliminaryspace structure of risk perception,characteristic of group,etc.Results fromdifferent research methods are correlative,and high rellability,criterion-related validity has been shown.
       The experimental research is an extension of the questionaire research.The fomer builds up a valid criterion behaviour for the latter.The results fromthe researchs of two different lines are interdepedent.
