赢者诅咒：心理机制、影响因素及应对策略

赢者诅咒是指在拍卖情境中, 竞价者为了获得拍卖品会过高估计其价值, 竞价成功以后当他发现其价值和自己之前的期望不一致时所产生的一种“诅咒”心理。赢者诅咒现象普遍存在于企业的资产拍卖、兼并重组、博彩游戏、投资决策等领域。损失规避和过度自信理论是赢者诅咒的主要心理机制, 而其影响因素主要有竞拍商品价值的不确定性、竞价人数、信息因素和竞价经验等。赢者诅咒的应对策略主要包括联合竞标、信息共享和学习。未来对赢者诅咒的研究需要进一步探讨赢者诅咒的心理机制、研究范式及本土化等问题。     

Consciously monitored grasping is vulnerable to perceptual intrusions

The idea of functional differentiation between vision-for-action and vision-for-perception has been supported by evidence from different domains. According to this account, perception is based on consciously accessible, relative representations, whereas vision-for-action is performed in an analytic, automatic manner. Support for this idea comes from studies that showed that unlike perception, grasping movements are refractory to illusions and to Weber’s law. Yet, interactions between the systems may occur when an action is performed in a less automated fashion. To test this idea, we asked participants to monitor their fingers apertures in flight and to halt their movement for a short duration when they felt that their aperture reached a maximum amount. The results showed that movements in the monitored condition were biased by the Ponzo illusion and showed atypical adherence to Weber's law. These results show that action and perception are more likely to interact when movements are performed in a controlled manner.     

Differences in cognitive performance between informal caregivers and non-caregivers

ABSTRACT

Extensive literature exists documenting the relationship between stress and cognition. Caregiving for an individual with Alzheimer’s disease can be aunique and chronic stress experience due to the increasing dependency of the care-recipient as the disease progresses. The current study examines the relationship between stress and cognitive performance in 47 dementia caregivers compared to 47 noncaregiver control participants matched on age, gender, and education. Participants completed measures assessing stress (measured via the Perceived Stress Scale) and seven domains of cognition including episodic memory, working memory, executive functioning, attention, visuospatial processing, processing speed, and implicit memory. Results showed that caregivers had poorer performance than non-caregivers on certain measures of episodic memory, working memory, and executive functioning; while no significant differences were observed on measures of attention, visuospatial processing, processing speed, or implicit memory. In addition, when controlling for general stress, caregiver performance on measures of processing speed and visuospatial processing was also poorer than non-caregivers. By controlling for levels of general stress that may not be related to caregiving, these results show that differences in cognitive performance are unlikely to be explained by general stress alone.     

Re-reading Anscombe on ‘I’

According to a ‘Straight’ reading of Elizabeth Anscombe’s (1975 Anscombe, E. 1975. “The First Person.” In her Mind and Language, edited by S. Guttenplan, 45–65. Oxford: Oxford University Press. [Google Scholar]) ‘The First Person’, she holds a radically non-referring view of ‘I’. Specifically, ‘I’ is analogous to the expletive ‘it’ in ‘It’s raining’. I argue that this is not her conclusion. Her substantive view, rather is that if what you mean by ‘reference’ is a certain rich and recherché notion tracing to Frege, then ‘I’ is not a referring term. Her methodological point is that one shouldn’t be ‘bewitched by language’ into thinking that ‘I’, because of its syntax, must exhibit ‘reference’ in this sense.     

Exploring mystery: can Christian meditation at school nurture students’ relationships with God?

ABSTRACT

While there is growing international interest in meditation and mindfulness initiatives in schools, little research has focused on exploring the impact of such practices on students’ spirituality. This paper reports data from a mixed method study involving primary school classes engaged in the regular practice of Christian meditation between Years 4 to 6 in Catholic schools in New South Wales, Australia. Student focus group data (n = 114 students) and a student survey (n = 250 students) suggest Christian meditation offers an inclusive and ‘hospitable’ space for many students, where their spiritual well-being can be nurtured, including their connection to God. However, the findings suggest that accompanying dialogue with students around the purpose and possibilities of Christian meditation may help to better situate the practice as a ‘hospitable space’ thus enabling deeper engagement with the spiritual in contemporary Catholic classrooms.     

THE MORAL LEGACY OF COMMUNAL WRONGS: ETHNIC IDENTITY GROUPS AND INTERGENERATIONAL MORAL SENTIMENT

Abstract: Many individuals experience feelings of collective guilt or shame for the blameworthy historical acts of the nations or ethnic groups to which they belong. I reject the idea that collective moral sentiment rests on inherited moral responsibility. I suggest that the possibilities for individual action inherent in membership in ethnic identity groups can be a source of special moral duties. I argue that collective guilt and shame are moral emotions that individuals experience in response to complex assessments of their groups' histories and of their own practical responses to those histories. The approach I take to analyzing the concept of an ethnic identity group makes use of tools developed by Max Weber. Weber's conceptual work on social groups and related phenomena has been strongly criticized in a widely discussed book by Margaret Gilbert. I show that Gilbert's arguments fail to discredit Weberian analyses of social groups and their properties.     

Transforming churches: the lived religion of religious organizations in a contemporary context

ABSTRACT

This article analyzes patterns of transformation in a specific majority religious institution, the Evangelical Lutheran Church in Denmark (ELCD), through a case study of communicative actions related to new church practices. The argument is that the patterns most often identified in the study of the religion of late-modern individuals, which is an “ever-changing, multifaceted, often messy—even contradictory—amalgam of beliefs and practices” (McGuire 2008, 4), are also relevant when scholars describe changes at the level of religious organizations. Meredith McGuire’s concepts are supplemented with other discussions of the transformation of traditions in a contemporary context. Our research question is: what characterizes the communicative actions concerning the transformation of traditions within the ELCD today? The empirical material consists of communicative actions related to practices associated with Halloween and Valentine’s Day from two distinct contexts: 1) the public debate about the Church in the newspaper The Christian Daily and 2) public announcements in the official online Church calendar. This leads to a discussion of the creative agency of religious institutions as part of the complex pattern of contemporary religion. The article argues in favor of an increased focus on the development of new practices in churches as examples of lived religion at the level of institutional religion.     

Intimate Partner Violence (IPV) and Neurological Outcomes: A Review for Practitioners

ABSTRACT

Thirty-eight million women will experience intimate partner violence (IPV) during the course of their lifetime. Many of these women will experience brain injuries as a result of IPV and may not seek medical attention. Several types of practitioners who work with IPV survivors consistently, e.g., first responders, advocates, and clinicians, may be unfamiliar with brain functioning, screening, assessment, and treatment. This article reviews the dual traumas of IPV and TBI, the impact on neurological processes and symptomatology, and short and long-term outcomes. Recommendations for screening, intervention, interprofessional collaboration, and research are outlined.     

Characterization of visual scanning while driving for the identification of drivers’ profiles

Assessing the driving skills of people with cognitive or visual impairments is often complex. The analysis of visual exploration strategies can be a good solution to identify the implementation or not of good strategies of information search in the visual scene (adaptation and compensation). In this study, we compared the visual exploration behaviours of 26 healthy, 19 glaucoma and 21 elderly participants. For this purpose, we used a driving simulator for which a visual field measurement test had been adapted to obtain measurements in static and dynamic conditions. The dynamics of the gaze was also measured. Our results showed that each of the three groups of participants had specific characteristics of visual exploration. Using a classification algorithm, we were able to show that it was possible to identify the group which a participant belonged to on the basis of the visual exploration’s characteristics. This finding opens the door to many applications in the context of driving assistance and training.
