We examined the effects of two emotions, fear and anger, on risk‐taking behavior in two types of tasks: Those in which uncertainty is generated by a randomizing device (“lottery risk”) and those in which it is generated by the uncertain behavior of another person (“person‐based risk”). Participants first completed a writing task to induce fear or anger. They then made choices either between lotteries (Experiment 1) or between actions in risky two‐person decisions (Experiments 2 and 3). The experiments involved substantial real‐money payoffs. Replicating earlier studies (which used hypothetical rewards), Experiment 1 showed that fearful participants were more risk‐averse than angry participants in lottery‐risk tasks. However—the key result of this study—fearful participants were substantially less risk‐averse than angry participants in a two‐person task involving person‐based risk (Experiment 2). Experiment 3 offered options and payoffs identical to those of Experiment 2 but with lottery‐type risk. Risk‐taking returned to the pattern of Experiment 1. The impact of incidental emotions on risk‐taking appears to be contingent on the class of uncertainty involved. For lottery risk, fear increased the frequency of risk‐averse choices and anger reduced it. The reverse pattern was found when uncertainty in the decision was person‐based. Further, the effect was specifically on differences in willingness to take risks rather than on differences in judgments of how much risk was present. The impact of different emotions on risk‐taking or risk‐avoiding behavior is thus contingent on the type, as well as the degree, of uncertainty the decision maker faces.

In three experiments, this research provides new insights into branding by studying the psychological and neurophysiological mechanisms of how consumers relate to their beloved brands. The authors propose that emotional arousal decreases over the brand relationship span, while inclusion of the brand into the self increases over time. Results of experiment 1 indicate greater self-reported emotional arousal for recently formed brand relationships, as well as decreased emotional arousal and increased inclusion of close brands over time. Additionally, the moderating role of usage frequency of the brand brings out an interesting nuance of the way these effects operate. Experiment 2 measures skin conductance responses and reveals increased emotional arousal for recently formed close relationships but not for established close brand relationships, corroborating the results based on self-reported data. In experiment 3, a functional magnetic resonance imaging study reveals an association between established close relationships and activation of the insula, a brain area previously found to be a crucial mechanism in diverse but related psychological phenomena such as urging, addiction, loss aversion, and interpersonal love.  相似文献

The main objective of the present investigation was to analyze the relationship between self-reported schizotypal and borderline personality traits in a sample of 759 college students (M = 19.63 years; SD = 2.03). For this purpose, the Schizotypal Personality Questionnaire-Brief (SPQ-B; Raine and Benishay, 1995) and Borderline Personality Questionnaire (BPQ; Poreh et al., 2006) were administered. The results showed that schizotypal and borderline features are partially related at subclinical level. The exploratory factor analysis conducted on the subscales revealed a three-factor solution comprised of the following factors: Identity/Interpersonal, Lack of Control and Schizotypal. The canonical correlation analysis showed that schizotypal features and borderline personality traits shared 34.8% of the variance. The data highlight the overlap between schizotypal and borderline personality traits in nonclinical young adults. Future studies should continue to examine the relationship and the degree of overlap between these traits in community samples.  相似文献

Aging has been associated with several brain changes that often affect the cognitive functioning of adults, but changes in executive functions, particularly in the field of decision making, have not been fully investigated. The Iowa Gambling Task (IGT) is a widely used tool to evaluate decision making, but little is known about the effect of age on its results. This study used the IGT and compared healthy young (n = 40) and elderly (n = 40) adults to evaluate their decision making processes. There were significant differences in the learning curve of the two age groups, but no difference in overall IGT performance. The results for the first IGT block were different from those of the rest of the task, and the group of elderly adults had a better performance in this block. Elderly adults also showed a preference for deck A, the one that resulted in greater losses. Findings confirmed the results of other studies, which reported that the IGT block score is the variable with the greatest sensitivity to age in this instrument.  相似文献

Assessment of a sexual coercion prevention program for adolescents   总被引:1,自引:0,他引:1  
This study's focus is to evaluate a sexual coercion prevention program in adolescents. Using a before-and-after design with both a treatment group (n = 93) and a control group (n = 76), an intervention of seven sessions was completed. Said sessions included such content as conceptualizing sexual freedom, sexual coercion and voluntary consent, analyzing different sexual coercion tactics and the contexts in which they occur, empathy toward the victim, and developing abilities to avoid risky situations. Other risk factors for coercive behavior and sexual victimization are explored as well, such as alcohol use, sexist attitudes and inadequate communication, among others. The intervention's results include a decrease in stereotypical beliefs about the opposite sex and increased empathy toward victims of sexual coercion. These changes were maintained with the passage of time. Also, in the treatment group, a more acute decline was observed in the proportion of young people engaging in sexually coercive behaviors, This article emphasizes the importance, necessity and efficacy of such interventions, and discusses and analyzes possible improvements to the program for its future implementation.  相似文献

Although there have been several attempts to explore for beneficial effects of research participation in social sciences, most of them have mainly explored satisfaction and students learning perceptions (e.g., Bowman & Waite, 2003). Very few works have studied learning by measuring exam performance. Moreover, participation has been usually conceptualized as a mixture of active and passive participation, including in the same measure different practices such as filling up questionnaires, running experiments or reading and answering questions about a journal article or a scientific conference. The present work tries to determine if there is an advantage due to research participation comparing exam performance, satisfaction and perceived learning of the matter Research Methods in Psychology, in three different groups (non-participating, passive and active participating). As we can see in the results, the mere participation benefits exam performance. Results are discussed in terms of the use of research participation as a new powerful active method in education.  相似文献

The aim was to examine the factors involved in people's willingness to make a living organ donation. A convenience sample of 200 people in southern France rated willingness to be a living donor in 48 scenarios consisting of all combinations of five factors: recipient's identity (close family member and city resident); donor's surgical risk (little and some); donor's possible long-term health consequences (none, some lessening over time, and durable); transplant success ("generally durably successful" and "durably successful one time out of two"); and likelihood of other donors (subject is one of the rare compatible donors or one among others). Cluster analyses showed the existence of three distinct organ donation philosophies. For the largest cluster (49% of participants), willingness to donate was very high to a family member, but low to a city resident. For the second cluster (37%), willingness was high to family, but also moderately high to a city resident. For the third cluster (14%), willingness was always low. Thus, most participants judged themselves ready to make a living organ donation to a family member and many even to a stranger.  相似文献

At the beginning of the 21st century, the punishment strategies used by the Spanish administration were considerably hardened to achieve a reduction in road accidents. This hardening could also be seen in the mass-media public advertising campaigns, with a marked shift from gentle messages to threat-based advertisements.The goal of this study is to evaluate the effectiveness of this radical change in terms of main road accident indicators and the time that the effects last using multivariate unobserved component models set up in a state space framework applied to monthly series for the 1980–2008 period. The main conclusion is that the effect on reducing road accidents is no greater when citizens are subjected to a greater level of threats in advertising campaigns than would on average be achieved using campaigns with a low level of threats. Secondly, the impact of bloody advertising in Spain is limited to the most serious accidents, those that cause deaths, either on highways or in built-up areas. Moreover, the positive effects progressively decrease as the average lifespan for significant effects of medium and high level campaigns on deaths on highways or in built-up areas was 8 months and almost 12 days. The results show that a reduction in numbers of deaths and injuries is always achieved when the level of harshness in the messages is increased after a period of several years of mild advertising.  相似文献
