Fairness and bargaining power in threshold public goods experiments

Experiments on three two‐person threshold public good provision games, namely, the simultaneous, sequential, and dictator games, are conducted to explore the motives behind giving. Players who move simultaneously are endowed with equal bargaining power, and players who move first are endowed with more bargaining power than players who move subsequently. Dictators are indubitably endowed with complete bargaining power. Since the differences between the bargaining powers of two players increase from the simultaneous to the sequential to the dictator game, comparisons among games allow us to trace whether the contribution behavior is motivated by fairness or is simply due to the strategic concern. The experimental evidence shows that the strategic concern explains the overall contribution behavior better than the motive of fairness. However, in the final round 26% of the dictators share the threshold evenly with their opponents, suggesting that some subjects do play fairly. Copyright © 2007 John Wiley & Sons, Ltd.     

Comparing the Actual and Expected Persuasiveness of Evidence Types: How Good are Lay People at Selecting Persuasive Evidence?

Whereas there are many publications in which argumentation quality has been defined by argumentation theorists, considerably less research attention has been paid to lay people’s considerations regarding argument quality. Considerations about strong and weak argumentation are relevant because they can be compared with actual persuasive success. Argumentation theorists’ conceptions have to some extent been shown to be compatible with actual effectiveness, but for lay people such compatibility has yet to be determined. This study experimentally investigated lay people’s expectations about the persuasiveness of anecdotal, statistical, causal, and expert evidence, and compared these expectations with the actual persuasiveness of these evidence types. Dutch and French participants (N = 174) ranked four types of evidence in terms of their expected persuasiveness for eight different claims. Both cultural groups expected statistical evidence to be the most persuasive type of evidence to other people, followed by expert, causal, and, finally, anecdotal evidence. A comparison of these rankings with the results of Hornikx and Hoeken (Communication Monographs 74, 443–463, 2007, Study 1) on the actual persuasiveness of the same evidence types reveals that people’s expectations are generally accurate: How relatively persuasive they expect evidence types to be often corresponded with their actual persuasiveness.

模拟员工招聘过程中的有意遗忘效应

以隐私信息和非隐私信息为目标信息,以66名大学生为被试,采用类似字表范式,探讨了模拟员工招聘过程中三种提示条件下的有意遗忘效应。结果发现:①在模拟员工招聘过程中,有意遗忘效应显著,不同的提示会影响决策的结果;②简历上的与工作无关的个人隐私信息对招聘者的决策过程有一定的消极影响;③一定的干预手段可以部分消除个人隐私信息对聘用决策的消极影响,但不能完全消除。     

The paradox of the disrespected: Disrespected group members’ engagement in group-serving efforts

Previous research has demonstrated that intra-group respect can strengthen people’s group identification, and encourage them to exert themselves on behalf of their group. In the present contribution, we focus on the possibility that those who are not respected by other group members (i.e., the disrespected) can also display group beneficial behavior. Experiment 1 (N = 159) confirms this paradoxical premise and reveals that systematically disrespected group members indeed exert themselves on group-serving tasks. These findings were replicated in Experiment 2 (N = 110). Additional indicators in Experiment 2 demonstrate that the effort by systematically disrespected group members cannot be attributed to a desire to improve their acceptance in the group, but should be interpreted as attempts to assert the worth of the self separately from the group. Results are discussed in relation to the group-value model and insights on marginal group membership and social exclusion.     

Contexts of the commitment–citizenship link: A test of economic volatility in a dual organization setting

Research interest on the commitment–performance link persists, and recent efforts have focused on investigating the contextual factors due to the mixed outcome of the empirical studies. However, very limited study has examined the influence of economic factors including economic volatility, and none in the dual setting of the organization and the union. This study investigated the contextual influence of perceived inflation—an economic volatility construct—on commitment and extra-role performance. Exchange theory, with support from psychological contract and equity theories, was used to postulate two parallel, but competing models of the organization and the union. Using a sample of 247 unionized employees in southern U.S.A., the study tested the moderating effect of perceived inflation on the relation between commitment and citizenship intent. The results revealed three-way interactive effects in both models, in a dual commitment setting. Thus, the economic volatility construct acts as a situational constraint on the link between the attitudinal-based commitments and citizenship intent, but in the contexts of obligation and cost-based commitments to the organization and the union respectively. The implications of these mitigated effects are discussed.     

Forming and reacting to overall fairness: A cross-cultural comparison

This study compared the cross-cultural formation and reactions toward overall fairness perception of employees from the US, China, Korea, and Japan. Distributive justice was related to overall fairness less strongly for Americans and Japanese than for Chinese and Koreans. In contrast, interactional justice was related to overall fairness more strongly for Americans and Japanese than for Chinese and Koreans. As expected, materialism seems to provide a coherent account of these cultural differences. In addition, overall fairness showed a stronger effect on turnover intention for Americans than for Chinese and Koreans. For job satisfaction, the effect of overall fairness was stronger for Americans than for Chinese, Koreans, and Japanese. Power distance seems to provide an adequate account of these cultural differences.     

The relation between worrying and concerns: the importance of perceived probability and cost

The relation between worrying and individuals' concerns was examined in a sample of 197 college students. Participants described the five undesirable outcomes that they thought about most often, indicated how likely they thought the outcomes were, and how upset they would be by them. Worry severity was measured using the Penn State Worry Questionnaire. The relation between worry severity and the life domains about which individuals were concerned was quite weak. In contrast, as predicted, greater worry was associated with higher probability and cost estimates. In addition, cost estimates moderated the relation between worry severity and probability estimates. The potential importance of perceived threat for understanding worrying is discussed.     

Influence of expressed emotion and perceived criticism on cognitive-behavioral therapy for social phobia

This study examined significant others' expressed emotion (EE) and a closely related construct, perceived criticism, as predictors of cognitive-behavioral therapy outcome in a sample of 40 patients with social phobia (social anxiety disorder). Patients enrolled in group therapy for social phobia completed pre- and post-treatment questionnaire measures of perceived criticism and anxious and depressive symptoms. Designated significant others were assessed for the components of high EE (criticism, hostility and emotional overinvolvement) using the Camberwell Family Interview. It was hypothesized that these high-EE components and patients' perceived criticism would be associated with poorer treatment outcome, and results ran counter to these expectations. Controlling for initial social phobia severity, lower levels of perceived criticism predicted treatment dropout. There was also a nonsignificant trend for participants with a significant other rated as high in emotional overinvolvement to show less change on a composite symptom measure. Findings from this study suggest that close relationships impact the outcome of cognitive-behavioral interventions for social phobia.

Perceived Social Support and Caregiver Strain in Caregivers of Children with Tourette’s Disorder

The research on Tourette’s disorder (TD), a neuropsychological disorder consisting of motor and phonic tics, has largely focused on individuals with TD and not on the caregivers of children with TD. We investigated the effects of several variables on caregiver strain of caregivers of children with TD, including perceived social support, caregiver characteristics, and characteristics of the child’s disorder. An online survey was completed by 140 caregivers of children with TD between the ages of 6 to 18 years. We performed a path analysis to examine the outcome of caregiver strain in relation to the research variables. Our results indicated that caregiver age, symptom severity of the child’s TD, and perceived social support accounted for variance in caregiver strain, and that perceived social support was a partial mediator of child’s symptom severity and caregiver strain. Symptom severity and caregiver strain were also related to the presence of other comorbid disorders, such as Oppositional Defiant Disorder (ODD), anxiety, or Attention Deficit Hyperactivity Disorder (ADHD) when compared to children either having no other comorbid disorders or other types of disorders.
