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.

叙事医学反思性写作对共同决策价值探析

以叙事医学工具反思性写作为切入点,首先从医方、患方及外部环境三个角度分析了当前医患共同决策所面临的临床实践困境,其次在对反思性写作概念、实践特点概述的基础上,提出了叙事能力对临床工作的重要性、叙事医学伦理对决策困境的作用,最后从促使医方自我反思,避免引导式决策及权威主义;弥合医患视阈差异,达成决策共识;阐明并澄清患者偏好及价值观,促进个体化共同决策;提高患者参与决策意愿,调动参与决策积极性;缓和医患关系,实现医患共情,促进共同决策良性互动五个方面阐述了反思性写作对医患共同决策困境的助力作用。

Can music bring people together? Effects of shared musical preference on intergroup bias in adolescence

Recent research has successfully applied social identity theory to demonstrate how individuals use music as a basis for intergroup differentiation. The current study investigated how music might also be used to encourage the development of positive intergroup attitudes. Participants (N = 97) were allocated to one of two experimentally created social groups and then led to believe that the groups had similar or different musical preferences. They then evaluated each group and reported their perceptions concerning how they expected their own group to be evaluated by the other group. Participants who believed the groups had similar musical preferences reported more positive intergroup attitudes relative to a control group; they also expected to be evaluated more positively by members of the other group. However, positive intergroup perceptions were also reported by those who believed the two groups had different musical preferences. The implications of these findings for theory and practice are discussed.     

Narrating career, positioning identity: Career identity as a narrative practice

In contrast to traditional definitions of career identity as an individual construct, this article argues for a discursive approach to career identity as a narrative practice. Career identity is conceptualized as a practice of articulating, performing and negotiating identity positions in narrating career experiences. By using the concept of positioning, this approach situates identities within particular historic, cultural and interactional contexts via the discourses and master narratives that position identity. It also leaves space for individual agency and change via the reflexive capacity of the person to modify and negotiate the competing positions available. The methodological implications are considered, and illustrated with an empirical case analysis. The contribution of the proposed approach is in offering contextualized understandings of actual practices, resources and constraints of identity construction while also allowing for in-depth analyses of the particularities of identity work and possibilities for change in careers.     

The Identity of,and the Difference between,Analytical and Continental Philosophy

This paper intends to invoke the spirit of Hegel as the éminence grise behind analytical and continental philosophy. Both movements can be seen to originate in, or to receive a strong impetus in their development from, a repudiation of Hegel. Even Russell's quest for a systematic logical analysis of language may be seen as an attempt at a quasi- or anti-Hegelian systematicity. The collapse of this systematicity has led to the celebration of difference in both the analytical and continental schools. Another feature of contemporary philosophy is the priority given to invention and creativity over discovery. In this respect, Nietzsche is the master-figure underlying all contemporary allegiance to, and indeed, obsession with, the twin idols of creation and difference.
