How does preference reversal appear and disappear? Effects of the evaluation mode

Preference reversal is a systematic change in the preference order between options when different response methods are used (e.g., choice vs. judgment). The present study focuses on procedures used to elicit preferences according to an evaluability hypothesis. Two experiments compared joint vs. separate evaluations and explicit vs. non‐explicit joint evaluations. Subjects had to express preferences between high‐variance gambles (HVGs) and low‐variance gambles (LVGs) either by choosing one gamble to play in a lottery or by assigning gambles minimum selling prices. We show that HVGs are preferred in both choice and pricing conditions when gambles are evaluated separately, and LVGs are preferred in both choice and selling conditions when gambles are evaluated in pairs: i.e., when the evaluation mode is held constant, classic preference reversal disappears. These results support the evaluability hypothesis, and suggest that preferences depend on whether subjects are allowed to compare the options they are asked to choose from or judge, independently of the nature of the scale (i.e., attractiveness vs. minimum selling price) they are required to adopt.

Testing boundary conditions for the conjunction fallacy: effects of response mode, conceptual focus, and problem type

Two experiments used within-subject designs to examine how conjunction errors depend on the use of (1) choice versus estimation tasks, (2) probability versus frequency language, and (3) conjunctions of two likely events versus conjunctions of likely and unlikely events. All problems included a three-option format verified to minimize misinterpretation of the base event. In both experiments, conjunction errors were reduced when likely events were conjoined. Conjunction errors were also reduced for estimations compared with choices, with this reduction greater for likely conjuncts, an interaction effect. Shifting conceptual focus from probabilities to frequencies did not affect conjunction error rates. Analyses of numerical estimates for a subset of the problems provided support for the use of three general models by participants for generating estimates. Strikingly, the order in which the two tasks were carried out did not affect the pattern of results, supporting the idea that the mode of responding strongly determines the mode of thinking about conjunctions and hence the occurrence of the conjunction fallacy. These findings were evaluated in terms of implications for rationality of human judgment and reasoning.     

大学生英语学习策略使用特点及发展趋势研究

采用自编问卷对493名不同背景大学生英语学习策略的调查发现,大学生内隐学习策略显著低于外显策略,表明我国大学生英语学习以外显为主;外显策略中,社会/情感策略水平最高,而元认知策略水平最低;英语学习策略的使用在性别、英语学习难易程度的主观判断以及学业成就水平等因素上呈现出明显的差异性特点,女生的策略使用率总体高于男生,英语学习成就越高以及英语学习认知越积极的学生学习策略使用率越高;大学生英语学习策略的发展呈V型趋势,在大三低至谷底,男生的策略波动幅度显著大于女生。     

新型农村合作医疗中的道德风险及防范

以“新乡模式”为例对商业保险公司参与承办新型农村合作医疗进行了有益的探索。对商业保险公司利益激励不足致使其参与新农舍的积极性不高,而激励不足主要是源于制度不足导致对新农合中的道德风险约束无力。探讨了对道德风险的防范措施。     

Expected consequences of anger‐related behaviours

In a study with 140 participants (66 men, 74 women), we investigated behaviour outcome expectancies (cognitive, affective and relational) regarding a broad group of anger‐related behaviours (e.g. hit someone, run away). Results of a three‐mode component analysis indicated that behaviour outcome expectancies vary considerably, depending on the behaviour (aggressive versus nonaggressive ones), the consequence (consequences related to the self versus consequences for the anger) and the individual. The findings are discussed in the context of catharsis theory, emotion regulation and functionalistic accounts of emotion‐related behaviour. Copyright © 2006 John Wiley & Sons, Ltd.
