This dissertation is concerned with the role of regret aversion in decision making. Specifically, it examines how regret aversion influences decision process, choice, and post-decisional behaviors and feelings. Chapter 1 provides an overview of the past empirical findings and theorizing on regret aversion. Chapter 2 examines whether regret aversion leads to a stronger or weaker preference for so-called reason-based choices (cf., Shafir, Simonson, & Tversky, 1993), or options that are more easily justifiable. Specifically, four experiments test whether four well-known reason-based choice effects are amplified or attenuated when regret is made salient. These effects are the asymmetric dominance effect, the compromise effect, the select/reject effect, and the most important attribute effect. Chapter 3 reports on five experiments that examine whether regret aversion leads decision makers to engage in more careful decision processing as suggested by Janis and Mann (1977). It extends the study of regret aversion from choice behavior to decision processing. Chapter 4 studies the effects of regret aversion in repeated decisions. Specifically, it examines experimentally how decision makers handle the trade off between seeking feedback on foregone options that may facilitate learning and better decision making in future decisions, and avoiding feedback on foregone options as such feedback may cause feelings of regret. Chapter 5 summarizes the contributions of this dissertation and concludes.

The sexual abuse by Roman Catholic clergy has overwhelmed public media and has resulted in a barrage of criminal and civil lawsuits. Between October of 1985 and November of 2002, more than three-hundred and ninety-four media sources reported on allegations of sexual misconduct worldwide. The response by the hierarchy of the church has been defensive with little effort in expressing remorse. Researchers over the past decade have focused much attention on how organizations respond to crises involving allegations of wrongdoing, but little attention to the church as an organization remains under-researched. When an organization suffers such a crisis as did the Catholic Church regarding the sexual abuse of its members, the role of apology takes on various viewpoints. The questions posed for this research are: First, what strategies of apology did the Catholic Church use in addressing the sexual abuse by clergy and were the apologies issued apologies of regret or remorse. Secondly, I want to explore the impact the media has had on the church. Finally I want to explore the status of the church today with regard to legal issues and the effect the statute of limitations is having on the victims being compensated. The apologies issued on behalf of the Church were few and far between. Based on the analysis of articles from the Boston Globe, it appears that the Church apologized as more of regret than remorse. The silence and cover-up by leaders in the Church forced the hand of many victims to speak out about the abuse and confront the Church in the only way they would respond . . . in a court of law. Once the accusations became public, the media played a pivotal role in escalating the crisis, thereby, forcing the hand of the Church in addressing the abuse. Taking responsibility for the actions of clergy from the very beginning would have been the responsible thing for the Church to do.

This dissertation contributes to a growing literature on affective forecasting showing that people are often inaccurate when predicting their future emotions, particularly the emotion of regret (Wilson & Gilbert, 2003). In the current program of research I explored the differences in the anticipated and experienced regret of participants who worked (or imagined working) either alone or as part of a group. In Experiment One I demonstrated that participants anticipated more regret from failing a task when alone than from failing a task that when working as part of a group. I speculated that this occurs because working with a group allows one to blame others for a failure, thus reducing one’s own regret. In Experiment Two I demonstrated that although participants anticipated more regret from an individual relative to a group failure, the regret they actually experienced is equivalent in these conditions. I hypothesised that this is because the psychological immune system (Gilbert, Pinel, Wilson, Blumberg, & Wheatley, 1998) works hard to reduce the regret of the participants who worked alone to levels matching that of the participants who worked in groups. I also demonstrated that this psychological immune system takes time to reduce regret differences in levels of regret were found between participants in the group and alone conditions when participants reported their regret immediately, but when regret was reported after a delay, these differences were no longer found. In Experiment Three I ruled out a potential confound by demonstrating that the differences between Experiments One and Two were not due to participants thinking of different time frames while reporting their regret. In Experiments Four and Five I extended my program of research by investigating whether the anticipated and experienced regret that is caused by failing a task varies depending on whether one is working with in-group or out-group partners. I found that while participants anticipate more regret from failing a task with an in-group compared to an out-group partner, the regret they ultimately experience is not affected by the group status of their partner. Implications and future directions are discussed. / Thesis (Ph.D, Psychology) -- Queen's University, 2010-09-10 15:45:04.097

This thesis introduces the basic concepts of the game theory. Necessary models and solution concepts are described. Follows the summary of the computational complexity of these concepts and corresponding algorithms. Poker is formalized as one of the game theory game models. State of the art algorithms for the ex- tensive form games are explained with the application to the Poker. The thesis also introduces the Annual Computer Poker Competition and participating pro- grams. Finally, new result about the extensive form games with many actions is presented.

The current study examines two psychological experiences—rationalization and regret—among smokers from Thailand and Malaysia and the behavioural impact of rationalization and regret—intentions to quit. More specifically, the goals of the study were not only to examine differences between the two countries in rationalization, regret, and intentions to quit, but also to explain country differences by using the psychological constructs of social norms and the cultural psychological construct of collectivism (via mediation and moderation analyses). The data were from the International Tobacco Control (ITC) Policy Evaluation Southeast Asia Survey, a cohort survey of representative samples of adult smokers in Thailand (N = 2,000) and Malaysia (N = 2,006). The ITC Southeast Asia Survey was conducted January-March 2005. Participants were asked to complete a 40-minute in-person survey. Thai smokers were more likely to have intentions to quit smoking than Malaysian smokers and this country difference in quit intentions were, in part, explained by differences between the two countries in rationalization and regret, and that those variables, in turn, were significant predictors of quit intentions. Next, the psychological constructs of social norms and the cultural psychology construct of collectivism were used to explain the country differences in rationalization and regret. Thai smokers were more traditional and family oriented (high in vertical collectivism) and thus, they are more sensitive about their social norm and familial rejections about smoking. This, in part, contributed the fact that Thai smokers, compared to Malaysian smokers, were less likely to rationalize and more likely to regret smoking. Finally, the predictive models of rationalization and regret for Thailand and Malaysia were mirror images. The current study points to the importance of understanding smokers’ rationalization and regret. Rationalization and regret are negatively related and have an important implication for future behaviour. Different social norms against smoking, which are shaped by different regulatory environments and cultural values, contribute to the country differences in rationalization and regret. This study has demonstrated the benefits/value of psychological constructs in understanding smoking in a cultural context.

When an individual experienced that the assumptions are different with the ones when he/she made decisions, and if the actual or imaginational current situations might be better given the information then, a kind of negative emotion named ¡§regret¡¨ emerges. Previous studies found that regret played similar roles in terms of satisfaction, repurchase behavior and intention of complain: regret lowers the satisfaction and repurchase behavior, and indirectly affects the intention of complain through low satisfaction. However, different results are found in the realm of willingness of word-of-mouth communications. Thus, this research combines the work of Zeelenberg & Pieters (2004a) and daily observations for the sake of discussing whether impression management factors causes consumers not to conduct negative word-of-mouth communications albeit regretting their previous decisions ¡V or even carry out positive word-of-mouth communications in extreme cases. The study served scenario design as the main method. Experiment 1 was used in determining the relation between subjects¡¦ word-of-mouth communication behaviorsand their level of regret. The decision category ¡§switch and maintain¡¨ is an indicatorof the subjects¡¦ level of regret. The results indicate that when subjects perceive¡§higher level of regret if experienced¡¨ (i.e. the decision category of switch), theywould possess significantly higher level of effect in word-of-mouth communications then subjects in the other category. The thesis added impression management in experiment 2, they are ¡udependence¡vand¡uself-monitoring¡v, in order to test whether would subjects be affected due to impression management behaviors in terms of the willingness to conduct negative word-of-mouth communications. The results indicate that whether the decision categories or level of experienced regret are served as the measurement of emotions, ¡§level of dependent¡¨ and ¡§level of self-monitoring¡¨ play significant harmonizing roles in communicating negative word-of-mouth information. Significant decrease of such willingness is found in the category of high level of dependent.
