内群体偏爱或黑羊效应?经济博弈中公平规范执行的群体偏见

公平规范执行代指人们自愿损耗利益来惩罚违反公平原则行为的意愿和行为, 被视为人类社会的重要特征及维持合作行为的关键因素。群体认同是指个体对其所属群体身份的知觉及其所付诸于该群体身份上的价值与情绪, 直接影响着群际互动中人们的公平规范执行行为。基于多种资产分配任务, 国内外学者发现公平规范执行中群体偏见存在两种矛盾的表现形式：人们有时更愿意接受内群体成员的不公提议, 表现为内群体偏爱现象(the in-group favoritism, IGF), 有时又更愿意拒绝内群体成员的不公提议, 表现出黑羊效应(the black sheep effect, BSE)。当前, 纯粹偏好理论和规范聚焦理论常被用来解释上述两种相悖的现象。未来研究应侧重从多种视角揭示公平规范执行偏见的边界条件, 比较多种线索操纵所致偏见的差异性, 促进两种理论的融合与补充, 并增强其潜在神经机制的探索。     

A semiparametric approach for item response function estimation to detect item misfit

When scaling data using item response theory, valid statements based on the measurement model are only permissible if the model fits the data. Most item fit statistics used to assess the fit between observed item responses and the item responses predicted by the measurement model show significant weaknesses, such as the dependence of fit statistics on sample size and number of items. In order to assess the size of misfit and to thus use the fit statistic as an effect size, dependencies on properties of the data set are undesirable. The present study describes a new approach and empirically tests it for consistency. We developed an estimator of the distance between the predicted item response functions (IRFs) and the true IRFs by semiparametric adaptation of IRFs. For the semiparametric adaptation, the approach of extended basis functions due to Ramsay and Silverman (2005) is used. The IRF is defined as the sum of a linear term and a more flexible term constructed via basis function expansions. The group lasso method is applied as a regularization of the flexible term, and determines whether all parameters of the basis functions are fixed at zero or freely estimated. Thus, the method serves as a selection criterion for items that should be adjusted semiparametrically. The distance between the predicted and semiparametrically adjusted IRF of misfitting items can then be determined by describing the fitting items by the parametric form of the IRF and the misfitting items by the semiparametric approach. In a simulation study, we demonstrated that the proposed method delivers satisfactory results in large samples (i.e., N ≥ 1,000).     

"A right to lead": The role of leader legitimacy on group reactions to transgressive leadership

Research on the transgression credit shows that groups may sometimes turn a blind eye to ingroup leaders who transgress moral norms. Although there is substantial research investigating the underlying criteria of what makes a “good” leader, research often neglects to investigate the role of followers in leader-group dynamics. In this paper, we offer a novel approach to transgressive leadership by proposing that leader legitimacy is a key factor that determines whether followers’ reactions to transgressive leaders are positive or negative. Across two experiments, participants ascribed transgression credit only to transgressive ingroup leaders perceived as legitimate (Studies 1–2, total n = 308). Transgressive illegitimate leaders were viewed as more threatening to the group, were targeted for formal punishment, received less validation for their behavior, triggered negative emotions (anger and shame), and raised higher consensus for their removal from the leadership position than did legitimate leaders. This effect also occurred irrespective of the absence of formal social control measures implemented toward the transgressive leader (Study 2). Mediation analysis showed that leader illegitimacy triggered stronger feelings of group threat and stronger negative emotions which, consequently, fuelled agreement with collective protest against the transgressive leader. Theoretical and practical implications of these findings are discussed.     

A bright side of sadness: The depolarizing role of sadness in intergroup conflicts

Intractable conflicts constitute violent and threatening environments that lead to intense emotions and polarized attitudes. Sadness is one emotion frequently elicited by the price of such conflicts. This investigation characterized the effects of sadness on conflict‐related information processing and attitudes in the Israeli–Palestinian conflict. Findings from four experimental studies suggest that both incidental and integral sadness can induce a depolarization of political attitudes. In Study 1 (N = 163), sadness reduced the effect of political ideology on conflict‐related decisions. Sadness reduced the effect of political ideology on in‐group bias in resource allocation in Studies 2 (N = 213) and 4 (N = 274), willingness to negotiate in Studies 1 and 3 (N = 174), and openness to information supporting the out‐group's perspective (Study 4). Overall, in addition to its more negative implications, these results suggest that sadness (compared to both the non‐emotional and anger conditions) may have a bright side, since it may induce depolarization of political attitudes in intractable conflicts.

A Preliminary Examination of the Acceptability,Feasibility, and Effectiveness of a Telehealth Cognitive-Behavioral Therapy Group for Social Anxiety Disorder

In light of the growing interest in, and need for, the telehealth delivery of health care, additional research is needed on the acceptability and effectiveness of these types of interventions. This study examined the acceptability, feasibility, and preliminary effectiveness of an adapted telehealth-delivered group cognitive-behavioral therapy (CBT) intervention for adults with social anxiety disorder (SAD). This report describes the adaptation and subsequent implementation of an 8-week telehealth-delivered group treatment designed to reduce symptoms of SAD. Specific adaptations for delivering treatment during the COVID-19 pandemic and the subsequent enactment of social distancing measures are discussed. Posttreatment data indicated that the intervention was feasible to implement in an outpatient mental health clinic, acceptable to participants, and associated with reduction in symptoms of social anxiety, general anxiety, depression, and stress.     

Intergroup helping during the coronavirus crisis: Effects of group identification,ingroup blame and third party outgroup blame

Two studies tested predictors of helping across national boundaries. British participants reported blame attributions for the coronavirus crisis, either to the British government (ingroup blame), or to the Chinese government (third party outgroup blame), and it was tested whether this was associated with intentions to donate money to help outgroup members suffering from effects of the coronavirus crisis in the world's poorer countries. It was hypothesized that strength of identification with the national ingroup would be negatively associated with blame attributions to the ingroup, and that it would be positively associated with blame attributions to a third party outgroup. Blame attributions were predicted in turn to be related to outgroup helping, with ingroup blame being positively associated with helping intentions, and third party outgroup blame being negatively associated with helping intentions. Support for these predictions were found in one exploratory (N = 100) and one confirmatory (N = 250) study.

大量行为研究表明,个体对4以上非符号数量的加工存在加工机制分离现象,但是相关的神经机制研究还很少。本研究选取21名大学生被试,结合ERP技术和数量判断任务,以数量比率效应为指标,比较4以上不同大小数量加工的神经反应模式。结果显示,大小数量加工条件下数量比率效应对P2p成分幅值的调节模式存在显著差异。这支持了小数量加工基于数量属性,大数量加工基于非数量属性的观点。     

“Poor is pious”: Distinctiveness threat increases glorification of poverty among the poor

The current study examines whether a threat to group distinctiveness motivates the poor to glorify poverty as an identity management strategy. Research shows that threat to ingroup distinctiveness can motivate people to positively differentiate their group from similar outgroups on relevant dimensions of comparison. Little is known however about whether such processes would occur also with respect to devalued group characteristics that are not reflective of explicit group norms. This question is of high theoretical and practical importance because it can illustrate that people internalize and glorify even adverse traits as means of managing their social identity when faced with threat. We therefore tested whether among a poor community, individuals would glorify poverty when faced with distinctiveness threat. We collected data from Haredim (ultra‐Orthodox Jews), a poor and highly religious population in Israel. Across two experiments, we manipulated distinctiveness threat via inducing similarity between Haredim and seculars in Israel. We found that poverty was reconstrued as positive and desirable following distinctiveness threat, but only among Haredim who have a high commitment to group norms (Study 1) and who strongly justify their own social system (Study 2). Theoretical and applied implications of the findings are discussed.
