集体自恋：群际冲突的催化剂

集体自恋是将自恋延伸到群体水平的一个经典构念, 目前被界定为对于“自身所属群体是卓越的并值得优待, 却未充分被他者承认”的信念。现有研究发现它对群际敌对性有较强解释力, 因为集体自恋者对内群体形象、地位或身份所受威胁高度敏感, 容易高估威胁和怀疑外群体, 而缺乏自我价值感及控制感是集体自恋的重要根源。鉴于现有研究一般都预设了集体自恋的脆弱性和消极性, 而集体自恋的属性不必然如此, 未来研究应在充分厘清集体自恋内涵及结构的基础上探索其消极与积极后效, 揭示其多元成因及干预方法, 并推进跨文化研究。     

Multilevel Model Prediction

Multilevel models are proven tools in social research for modeling complex, hierarchical systems. In multilevel modeling, statistical inference is based largely on quantification of random variables. This paper distinguishes among three types of random variables in multilevel modeling—model disturbances, random coefficients, and future response outcomes—and provides a unified procedure for predicting them. These predictors are best linear unbiased and are commonly known via the acronym BLUP; they are optimal in the sense of minimizing mean square error and are Bayesian under a diffuse prior. For parameter estimation purposes, a multilevel model can be written as a linear mixed-effects model. In this way, parameters of the many equations can be estimated simultaneously and hence efficiently. For prediction purposes, we show that it is more convenient to retain the multiple equation feature of multilevel models. In this way, the efficient BLUPs are easy to compute and retain their intuitively appealing recursive form. We also derive explicit equations for standard errors of these different types of predictors. Prediction in multilevel modeling is important in a wide range of applications. To demonstrate the applicability of our results, this paper discusses prediction in the context of a study of school effectiveness.

Unbalanced triangle in the social dilemma of trust: Internet studies of real‐time,real money social exchange between China,Japan, and Taiwan

Using a dyadic game theory paradigm, three experiments on the social dilemma of trust were conducted over the Internet in real time, involving real money. It was predicted and found that in‐group favouritism in trusting behaviour was contingent on historical relationships between societies. In the China–Japan experiment, mainland Chinese but not Japanese trusted and made fair allocations to in‐group members more than out‐group members, and out‐group trust was best predicted by positive stereotypes of the out‐group for Chinese and identity for Japanese. In the China–Taiwan experiment, Taiwanese but not Mainland Chinese trusted in‐group members more than out‐group members, and in‐group trust for Taiwanese was best predicted by perceptions of current realistic threats. In the Taiwan–Japan experiment, there were slight in‐group favouring tendencies in trust, and positive stereotypes of the out‐group were the best predictors of out‐group trust. Japanese were unique in not displaying in‐group favouring behaviour at all, whereas both Chinese and Taiwanese were context specific in their in‐group favouritism. Stereotypes, social identities, perceptions of realistic threat, and historical anger made significant contributions to predicting trusting behaviour, but overall these survey measures only accounted for small and inconsistent amounts of variance across the three experiments.     

谁是最大的受害群体:群际受害者竞争

长期冲突的群体双方都致力于建构自己的最大受害者角色,他们认为自己比对方遭受了更多、更不公平、更不合理的伤害,这种现象称之为群际受害者竞争。群体通过强调冲突给自身造成的伤害后果的严重性与不公平性、伤害的处理方式等,努力声称内群体比对方遭受了更多的伤害。集体受害感、冲突责任归因、记忆的选择性、消除威胁的内在需要以及其他心理特点是群际受害者竞争的心理基础。通过构建"共同的受害者-侵犯者"认同以及增加群际接触等可以降低群际受害者竞争的水平,促进群际关系的和谐。今后的研究需要进一步完善群际受害者竞争的机制,深入探讨群际受害者竞争的其他影响因素,争取在干预策略上有所突破,关注非暴力冲突的群体情境中群际受害者竞争的特点,了解第三方群体对谁是最大受害者群体的认知和评价机制。     

Effects of school-based interventions on motivation towards physical activity in children and adolescents: A systematic review and meta-analysis

IntroductionAssuming that motivation is the key to initiate and sustain beneficial health behaviors, the aim of this systematic review was to analyze the effects of school-based physical activity interventions on a variety of motivational outcomes towards PA in school-aged children and adolescents.MethodsA comprehensive literature search was carried out in six electronic databases to identify randomized controlled trials and quasi-experimental trials examining the effects of PA interventions implemented during the regular school day, e.g., during physical education lessons or lunch breaks. Primary outcomes of interest were students' motivation, basic psychological needs, goal orientation, enjoyment, and motivational teaching climate in physical education. Meta-analyses were conducted for these outcomes using Comprehensive Meta-analysis software. Secondarily, intervention effects on students' PA behaviors were examined and the findings summarized narratively. Methodological quality of studies was evaluated using the Cochrane Collaboration's tool for assessing risk of bias for randomized trials; certainty of evidence on outcome level was evaluated using the GRADE approach.ResultsIn total, 57 studies carried out between 2001 and 2018 were included in this review. Sixteen individual meta-analyses were performed and revealed significant pooled effects for the outcomes enjoyment (g = 0.310), perceived autonomy (g = 0.152), identified regulation (g = 0.378), intrinsic motivation (g = 0.419), self-determination index (g = 0.672), task/mastery climate (g = 0.254), ego/performance climate (g = −0.438), autonomy supportive climate (g = 0.262), task goal orientation (g = 1.370), ego goal orientation (g = −0.188). The narrative data synthesis indicated an increase in students' PA behavior. The overall risk of bias was high across all studies and certainty of evidence of meta-analyzed outcomes ranged from very low to moderate. Moderate certainty of evidence was found for ego/performance climate and ego goal orientation. Conclusions: Meta-analyses suggest that school-based PA interventions may be effective in increasing a variety of motivational outcomes. However, the certainty of evidence was limited in the majority of outcomes. Further research is needed to identify effective intervention strategies that increase students’ motivation towards PA.     

Positive weighing of the other's collective narrative among Jewish and Bedouin‐Palestinian teachers in Israel and its correlates

Teachers play a pivotal role in the educational discourse around collective narratives, and especially the other's narrative. The study assumed that members of groups entangled in a conflict approach the different modules of the other's narrative distinctively. Jewish and Palestinian teachers, Israeli citizens, answered questionnaires dealing with the narrative of the other, readiness for interethnic contact, negative between‐group emotions and preferences for resolutions of the Israeli–Palestinian (I–P) conflict. Positive weighing of the other's narrative among Jewish teachers correlated with high levels of readiness for interethnic contact and low levels of negative between‐group emotions, across the various modules of the Palestinian narrative. Preferences for a peaceful resolution of the I–P conflict and rejection of a violent one were noted in two of the modules. Among Palestinian teachers, positive weighing of the other's collective narrative was exclusively noted for the Israeli narrative of the Holocaust, and this stance negatively related to negative between‐group emotions and preference for a violent solution of the I–P conflict, and positively related to readiness for interethnic contact and preference of a peaceful resolution of the conflict. Practical implications of these findings for peace education are discussed.     

Feasibility of and teacher preference for student‐led implementation of the good behavior game in early elementary classrooms

The Good Behavior Game (GBG) is a classwide group contingency shown to reduce disruptive student behavior. We examined the feasibility of training young students to lead the GBG in one first‐grade and three kindergarten classes. We also examined teacher preference for teacher‐led GBG, student‐led GBG, or no GBG using a concurrent chains procedure. We successfully trained students in all classes to lead the GBG, and the GBG reduced disruptive behavior regardless of who implemented it. Preference for who implemented the game varied across teachers. Results of this study suggest that students as young as kindergarten age can be trained to implement the GBG and that teacher preference should be taken into account when determining how classwide interventions are to be implemented.     

Teaching social perception skills to adolescents with autism and intellectual disabilities using video‐based group instruction

Few interventions focus on teaching social skills to adolescents with autism spectrum disorder (ASD) and intellectual disabilities (ID) that are consistently used during interactions with peers ( Carter et al., 2014). The present study evaluated the effects of video‐based group instruction (VGI) on the acquisition of social perception skills of five adolescents with ASD or ID in a public school setting. Social perception involves observing affective behaviors of others, discriminating relevant environmental stimuli, and differentially reinforcing the affective behavior of another person. Typically developing peers supported VGI implementation as social partners for participants. A multiple probe design across behaviors demonstrated the effectiveness of VGI for teaching social perception skills. Four of five participants acquired and maintained the targeted social perception skills, and we observed some transfer to a nontreatment setting. Results of this study suggest VGI may support the acquisition of social perception among adolescents with ASD or ID.     

Identifying predictive behavioral markers: A demonstration using automatically reinforced self‐injurious behavior

Predictive biomarkers (PBioMs) are objective biological measures that predict response to medical treatments for diseases. The current study translates methods used in the field of precision medicine to identify PBioMs to identify parallel predictive behavioral markers (PBMs), defined as objective behavioral measures that predict response to treatment. We demonstrate the utility of this approach by examining the accuracy of two PBMs for automatically reinforced self‐injurious behavior (ASIB). Results of the analysis indicated both functioned as good to excellent PBMs. We discuss the compatibility of this approach with applied behavior analysis, describe methods to identify additional PBMs, and posit that variables related to the mechanisms of problem behavior and putative mechanism of treatment action hold the most promise as potential PBMs. We discuss how this technology could guide individualized treatment selection, inform our understanding of problem behavior and mechanisms of treatment action, and help determine the conditional effectiveness of clinical procedures.
