A Test of Order-Constrained Hypotheses for Circular Data With Applications to Human Movement Science

Researchers studying the movements of the human body often encounter data measured in angles (e.g., angular displacements of joints). The evaluation of these circular data requires special statistical methods. The authors introduce a new test for the analysis of order-constrained hypotheses for circular data. Through this test, researchers can evaluate their expectations regarding the outcome of an experiment directly by representing their ideas in the form of a hypothesis containing inequality constraints. The resulting data analysis is generally more powerful than one using standard null hypothesis testing. Two examples of circular data from human movement science are presented to illustrate the use of the test. Results from a simulation study show that the test performs well.     

Naturalistic Fallacy Errors and Behavioral Science News: The Effects of Editorial Content and Cautions on Readers' Moral Inferences and Perceptions of Contributors

People commonly overestimate the intensity of their emotions toward future events. In other words, they display an impact bias. This research addresses the question whether people learn from their experiences and correct for the impact bias. We hypothesize that athletes display an impact bias and, counterintuitively, that increased experience with an event increases this impact bias. A field study in the context of competitive track athletics supported our hypotheses by showing that athletes clearly overestimated their emotions toward the outcome of a track event and that this impact bias was more pronounced for negative events than for positive events. Moreover, with increased athletic experience this impact bias became larger. This effect could not be explained by athletes' forecasted emotions, but it could be explained by the emotions they actually felt following the race. The more experience athletes had with athletics, the less they felt negative emotions after unsuccessful goal attainment. These findings are discussed in relation to possible underlying emotion regulation processes.     

Towards understanding pleasure at the misfortunes of others: The impact of self-evaluation threat on schadenfreude

In two experiments we demonstrated that a self-evaluation threat intensifies schadenfreude. Moreover, we showed that a self-evaluation threat predicts schadenfreude in both threat-related and threat-unrelated domains and when controlling for feelings of envy and dislike towards the target and evaluations of the misfortune in terms of deservingness. These findings indicate that another's misfortune may be pleasing because it satisfies people's concern for a positive self-view and a sense of self-worth.     

Regret and Responsibility Resolved? Evaluating Ordóñez and Connolly's (2000) Conclusions

T. Connolly, L. D. Ordo;aan;atez, and R. Coughlan (1997, Organizational Behavior and Human Decision Processes, 70, 73-85) argued, on the basis of 5 experiments, that regret need not be related to a sense of responsibility for the regretted outcome. We (M. Zeelenberg, W. W. van Dijk, & A. S. R. Manstead, 1998, Organizational Behavior and Human Decision Processes, 74, 254-272) showed in 2 experiments that this conclusion was premature, because it was based on an indirect measure of regret (i.e., overall happiness with the decision outcome). When regret was directly measured, the predicted effects of responsibility were found. L. D. Ordo;aan;atez and T. Connolly (2000, Organizational Behavior and Human Decision Processes, 81, 132-142) replicated our findings in 2 experiments. Based on their findings they arrived at 4 conclusions. In this rejoinder we first discuss Ordó?ez and Connolly's new studies and we then discuss the validity of their 4 conclusions. Copyright 2000 Academic Press.     

The perceived value of team players: a longitudinal study of how group identification affects status in work groups

Theory and research on status attainment in work groups primarily focuses on members’ abilities and characteristics that make them appear competent as predictors of their status in the group. We complement the abilities perspective with a social identity perspective by arguing that another important determinant of a member’s status is based on the extent to which the member serves the group’s interests. Specifically, we assert that a member’s identification with the group affects performance on behalf of the group, which in turn affects other members’ assessment of the member’s status. We test this social identity perspective on status attainment by studying the influence of members’ group identification on their performance and status in the group, while controlling for the members’ abilities and status characteristics. In a three-wave longitudinal field study following 33 work groups during a six-month group project, we find that members’ identification enhances their performance on behalf of the group, which in turn increases their status within the group. As such, our study advances insights in the determinants of status attainment in work groups and points to the relevance of the social identity approach for research on the antecedents of status in work groups.     

The effect of decision timing on the willingness to costly reward cooperation and punish noncooperation: Sanctioning the past,the present,or the future

Numerous studies have demonstrated that sanctions can promote cooperation. However, it is important to know not only that sanctions can work but also under what conditions people are actually willing to sanction cooperation positively (i.e., reward) or noncooperation negatively (i.e., punish). In this article, we demonstrate that people use sanctions less often and sanction more mildly when they decide about sanctioning before (instead of after) the occurrence of others' (non)cooperation (Experiments 1 and 2), regardless of whether they decide directly afterwards or after a time delay (Experiment 2). Moreover, we reveal that beforehand (as compared with afterwards) people have not yet formed clear sanctioning preferences (Experiment 3). These findings corroborate our reasoning that the decision environment beforehand induces nonconsequential reasoning and thereby hampers people's willingness to sanction. We discuss the theoretical, methodological, and practical implications of our work.     

Assessing the quality of child investigative interviewing in the Netherlands

Using evidence‐based guidelines to interview children is an important means to obtain complete and accurate accounts. In the current study, we examined the quality of child investigative interviewing in the Netherlands. To examine this, we compared the Dutch Scenario Model with the National Institute of Child Health and Human Development Protocol and interviews from countries that did not follow a specific protocol. Our principal result was that Dutch child interviewers rarely asked recommended open prompts that are known to elicit detailed and accurate testimonies from children. Furthermore, we found that the scenario model contained the highest number of directive questions compared with interviews from other countries. Our findings show that the Dutch Scenario Model is not well aligned with current research‐based recommendations for interviewing children.     

Resources and alternatives in coalition formation: The effects on payoff,self‐serving behaviour,and bargaining length

A consistent finding in coalition research is that the payoff of coalition members is related to (a) the resources they contribute to the coalition, and to (b) the number of alternative coalitions they can form. These two factors are, however, often intertwined. A greater number of resources tends to go hand in hand with a greater number of alternatives, leaving unanswered how both factors affect coalition behaviour. This paper attempts to clarify the interplay of resources and alternatives by disentangling the two in a newly developed coalition paradigm. Results indicated that participants base their payoff allocation on both resources and alternatives, but suggest that self‐serving behaviour is more related to alternatives. Furthermore, resources and alternatives had a distinct effect on the bargaining process. It was shown that differences in alternatives led to longer bargaining.

In money we trust? The use of financial compensations to repair trust in the aftermath of distributive harm

Trust is vital yet vulnerable in economic exchange relations. In these relations, a widely used strategy in response to distributive harm consists of having the transgressor pay a financial compensation to the victim. This research examines whether financial compensations can increase trust towards a transgressor, and whether the size of the compensation is relevant to this process. We hypothesized and found that whether larger compensations will elicit more trust, depends on how clear the perpetrator’s intention to transgress was. Experiment 1 revealed that trust perceptions increased more by a slight overcompensation of the inflicted harm as compared to an exact or a partial compensation, but not if the transgressor’s bad intentions became clear through the use of deception in the violation. In Experiments 2 and 3, we replicated these findings and further showed that it is not the use of deception per se, but rather the attribution of bad intent that moderates the effect of compensation size. Experiment 4, using a trust game paradigm revealed that this effect not only occurs for small overcompensations, but also for larger overcompensations.
