Abstract: Risk preference is a result-based trait. Seldom research have tried to link the process variables to it. Current study focuses on the relationship between risk preference and information process. Also, information integrity is regarded for its potential influence. In this study, the mouselab technology was used to explore the difference and similarity in information processing mode of high and low risk preference individuals. The subjects were 31 junior and senior students, including 16 high risk preference students and 15 low risk preference students selected according to a former career decision making questionnaire over 125 college junior and senior students. The selected 7 cues appeared in the mouselab rows, and 3 options appeared in the mouselab columns. Among the 7 cues, the former 6 cues were used to describe the option itself, and the last one was used to represent the possibility of getting the job. The study used a 2×2 (high risk preference/low risk preference) × (all information can be discovered/few information is unknown) design. Risk preference was tested between subjects, and information integrity was tested within subjects. The recorded dependent variables were as follows: (1) acquisition of information, the total click of one mouselab; (2) the mean hit rate of each cue; (3) depth of search, DS= the number of opened cells/the total number of cells. The results of the experiment showed that: (1) low risk preference individuals took more attention on the cue presenting the possibility of getting the job than high risk preference individuals; (2) when some information were missing, individuals tended to rely more on the cue presenting the possibility of getting the job; (3) the information integrity had no specific impact on information process and potential decision strategy; (4) the amount of information searched to make a decision had no significant change among different conditions although the useful information obtained was different. Current study discovers a potential linkage between risk preference and information process. The different risk preference may be due to the difference preference in obtaining or using the possibility information of a decision problem.

摘要： 本研究旨在探讨个体风险偏好如何影响信息加工过程；同时呈现信息的完整性是否影响个体信息加工过程。以31名正在求职的大学生为被试，探讨了他们在信息板上进行职业决策的信息加工过程。结果显示：(1) 低风险偏好者比高风险偏好者更关注与概率相关的线索；(2) 当信息不完整时，个体在决策中增加了对概率相关线索的关注；(3) 信息完整性对个体决策信息加工过程并未产生显著的影响。
