Power Relations and Group Aggregation in the Multiplicative AHP and SMART

The relative power of the members in a group of decision makers can be incorporated in the multiplicative AHP via power coefficients in the logarithmic least squares whereby we analyse the pairwise comparison matrices. When each decision maker judges every pair of alternatives under each of the criteria, aggregation over the criteria and over the decision makers proceeds via a sequence of geometric-mean calculations which can be carried out in any order, at least with predetermined criterion weights and power coefficients. Hence, since we preserve the rank order of the alternatives, we avoid a deficiency of the original AHP. We also consider SMART, an additive method which is logarithmically related to the multiplicative AHP so that power relations can easily be incorporated in it. Finally, in order to illustrate the proposed model, we analyse a generalized version of the well-known example of Belton and Gear as well as the power relations between member countries of the European Community. © 1997 by John Wiley & Sons, Ltd.

Examining the effects of group‐based instruction on emergent second‐language skills in young children

The present study evaluated the emergence of second‐language intraverbals in typically developing young children following a small‐group teaching intervention. Choral responding was employed with a group of 6 primary school children (5‐6 years old) to teach first‐language tacts (e.g., “What is this in English?” [“Hospital”]) and related second‐language tacts (e.g., “What is this in Welsh?” [“Ysbyty”]). A multiple‐probe design across stimulus sets was used to evaluate subsequent emergence of untrained first‐to‐second‐language derived intraverbals (e.g., “What is hospital in Welsh?” [“Ysbyty”]) and untrained second‐to‐first‐language intraverbals (e.g.,”What is ysbyty in English?” [“Hospital”]). Data indicated that the choral responding intervention produced robust increases in derived intraverbal relations for 3 of the 6 participants.     

A comparison of group contingencies on academic compliance

We used a reversal design with an embedded multielement design to compare the effects of an independent group contingency and a randomized dependent group contingency on compliance with assigned literacy worksheets in a first‐grade general education classroom. Nine participants were selected based on low levels of compliance in baseline or by teacher identification. Results indicated that both group contingencies increased compliance relative to baseline for the majority of participants. The independent condition produced higher levels of compliance for four students and the randomized dependent condition produced higher levels of compliance for one student. For four students, the two group contingencies were equally effective. A preference assessment indicated that the majority of target students preferred the randomized dependent condition and the majority of nontarget students preferred the independent condition. A number of potential explanations for our preference findings, including the possible role of obtained reinforcement, are discussed.     

Loyal peripherals? The interactive effects of identification and peripheral group membership on deviance from non-beneficial ingroup norms

For ensuring the well-being of groups, people are needed who deviate from ingroup norms that harm the group (“loyal deviance”). Qualifying previous results that loyal deviants have to be highly identified with the group, we hypothesize and show that this is only true when group members at the same time feel that they are highly prototypical for the group. No such effects occurred for peripheral members. In all three studies (N1 = 207, N2 = 115, N3 = 107), we measured people's intention to conform to a non-beneficial (vs. beneficial; Study 1) ingroup norm, self-investment in the group, and perceived (manipulated in Study 3) marginalization. Obviously, dissent from non-beneficial norms requires both a deep psychological investment in the group as well as secure ingroup membership. Implications are discussed.     

Support for collective action against refugees: The role of national,European, and global identifications,and autochthony beliefs

To understand recent anti-refugee protests in Europe, we examined how different levels of inclusiveness of group identities (national, European, and global) are related to intentions to protest among native Europeans. We focused on the mediating role of autochthony (a belief that the first inhabitants of a territory are more entitled) and the moderating role of threat. Survey data from 11 European countries (N = 1,909) showed that national identification was positively associated with autochthony, and therefore, with the intention to protest against refugees. In contrast, global identification was related to lower protest intentions via lower autochthony. These paths were found only among Europeans who perceived refugees as a threat. European identification was not related to the endorsement of autochthony or to collective action. These findings indicate why and when majority members are willing to participate in collective action against refugees, and underscore the importance of global identification in the acceptance of refugees.     

班级欺凌规范与欺凌行为：群体害怕与同辈压力的中介作用

本文通过两个研究探讨了群体因素中的班级欺凌规范如何通过同辈压力、群体害怕影响欺凌行为的发生。研究1为实验研究, 被试为186名小学高年级学生(M_age = 11.36 ± 0.99岁)。结果表明在不同情境(欺凌/非欺凌)的启动下, 各变量得分均具有显著差异; 进一步分析仅发现同辈压力的中介作用边缘显著。研究2为相关研究, 943名小学高年级及初二学生(M_age = 12.00 ± 1.32岁)填写班级欺凌规范、同辈压力和欺凌行为问卷。HLM分析显示同辈压力在班级欺凌规范与欺凌行为起显著中介作用。     

消极刻板印象和群际焦虑:阻碍群际交往的重要因素

消极刻板印象和群际焦虑是阻碍群际交往的重要因素。基于群际接触理论和群际焦虑理论模型,测量了少数民族和汉族交往时的群际焦虑水平、彼此持有的刻板印象和外群体态度等变量,考查了这些变量的特征及关系。结果表明:(1)汉族在群际交往过程中的群际焦虑水平显著高于少数民族;(2)女性比男性持有更积极的外群体态度;(3)消极刻板印象是产生群际焦虑和偏见态度的重要原因。减少消极刻板印象、降低群际焦虑是促进群际交往的重要途径。     

Infant gaze following depends on communicative signals: An eye‐tracking study of 5‐ to 7‐month‐olds in Vanuatu

Gaze is considered a crucial component of early communication between an infant and her caregiver. When communicatively addressed, infants respond aptly to others’ gaze by following its direction. However, experience with face‐to‐face contact varies across cultures, begging the question whether infants’ competencies in receiving others’ communicative gaze signals are universal or culturally specific . We used eye‐tracking to assess gaze‐following responses of 5‐ to 7‐month olds in Vanuatu, where face‐to‐face parent–infant interactions are less prevalent than in Western populations. We found that—just like Western 6‐month‐olds studied previously—5‐ to ‐7‐month‐olds living in Vanuatu followed gaze only, when communicatively addressed. That is, if presented gaze shifts were preceded by infant‐directed speech, but not if they were preceded by adult‐directed speech. These results are consistent with the notion that early infant gaze following is tied to infants’ early emerging communicative competencies and rooted in universal mechanisms rather than being dependent on cultural specificities of early socialization.
