This paper discusses simultaneous belief updates. I argue here that modeling such belief updates using the Principle of Minimum Information can be regarded as applying Jeffrey conditionalization successively, and so that, contrary to what many probabilists have thought, the simultaneous belief updates can be successfully modeled by means of Jeffrey conditionalization. 相似文献

The Hwang affair, a dramatic and far reaching instance of scientific fraud, shocked the world. This collective national failure prompted various organizations in Korea, including universities, regulatory agencies, and research associations, to engage in self-criticism and research ethics reforms. This paper aims, first, to document and review research misconduct perpetrated by Hwang and members of his research team, with particular attention to the agencies that failed to regulate and then supervise Hwang’s research. The paper then examines the research ethics reforms introduced in the wake of this international scandal. After reviewing American and European research governance structures and policies, policy makers developed a mixed model mindful of its Korean context. The third part of the paper examines how research ethics reform is proactive (a response to shocking scientific misconduct and ensuing external criticism from the press and society) as well as reactive (identification of and adherence to national or international ethics standards). The last part deals with Korean society’s response to the Hwang affair, which had the effect of a moral atomic bomb and has led to broad ethical reform in Korean society. We conceptualize this change as ethical modernization, through which the Korean public corrects the failures of a growth-oriented economic model for social progress, and attempts to create a more trustworthy and ethical society. 相似文献

This study took a close look at the mechanism behind gender disparity in video game usage by examining two perceptual variables: perceptions about others' video game usage and perceived influence of unrealistic video game character images on others. Both men and women perceived that young women play video games far less frequently than young men and also considered themselves less influenced by the unrealistic images than others. In addition, women, in comparison to men, perceived the video game images to have stronger influences on others. Furthermore, regression analyses revealed that perceived frequency of other women's video game play and perceived influence of the images on other women explained women's actual time spent on video games, but not men's time spent on video games. A discussion of these findings was provided, along with suggestions for video game developers, parents, educators, and video game researchers. 相似文献

In 3 experiments, the authors used a precuing protocol to examine the nature and cost of programming and the subsequent reprogramming of a movement's relative time and overall duration. Initial programming followed a fixed-order specification; knowledge of the necessary relative time was required before information regarding overall duration could be used in a manner that expedited response planning. In the case of reprogramming, however, when a modification had to be made in either the relative time or overall duration of the anticipated and already-prepared response, performers chose to completely reprogram the entire response. Complete reprogramming occurred even when the performer had correctly prepared the higher order relative-time component and only had to modify the overall duration of the movement. The data indicate that organizing movement timing before movement initiation is accomplished in a fundamentally different manner depending on whether the movement is being initially compiled or modified. 相似文献

O. K?hler (1926, 1927) found that less able performers tried harder as team members under conjunctive task demands (Kohler motivation gain effect) and that the greatest gain occurred with moderately discrepant coworker abilities (K?hler discrepancy effect). Recent investigations have reproduced K?hler's overall motivation gain but not the discrepancy effect. The present research examined whether workers' foreknowledge of task abilities--present in Kohler's research, absent in contemporary studies--moderates the discrepancy effect. Participants worked alone or in 2-person teams under conjunctive task demands. Experiment 1 manipulated foreknowledge of ability. Experiment 2 manipulated discrepancy: a (confederate) teammate performed slightly, moderately, or substantially better. Both experiments found (a) overall motivation gains and (b) discrepancy moderation under foreknowledge conditions. Implications for understanding group motivation gains are discussed. 相似文献

Clients' causal explanations for recalled important or helpful events between those of early and of late sessions of counseling interview have been examined. We predicted that (a) for clients' recalled important or helpful events, there will be more internal attribution in late than in early sessions and (b) clients' evaluation of counseling sessions would be positively related to their internal attribution of the recalled important or helpful events. Data were generated from 84 sessions of therapy, with 12 counselor-client dyads conducting seven sessions of therapeutic interviews each. Immediately after each interview, clients were requested to recall and explain the most important or helpful events that happened during the session. Clients' causal explanations of the events were analyzed by two trained judges. Results showed no statistically significant differences in frequencies of internal attribution. Similarly, internal attribution did not covary with clients' evaluation of counseling sessions. The implications of the results are discussed. 相似文献

The authors investigated the distinctiveness and interrelationships among visuospatial and verbal memory processes in short-term, working, and long-term memories in 345 adults. Beginning in the 20s, a continuous, regular decline occurs for processing-intensive tasks (e.g., speed of processing, working memory, and long-term memory), whereas verbal knowledge increases across the life span. There is little differentiation in the cognitive architecture of memory across the life span. Visuospatial and verbal working memory are distinct but highly interrelated systems with domain-specific short-term memory subsystems. In contrast to recent neuroimaging data, there is little evidence for dedifferentiation of function at the behavioral level in old compared with young adults. The authors conclude that efforts to connect behavioral and brain data yield a more complete understanding of the aging mind. 相似文献

Orientations to happiness and life satisfaction: the full life versus the empty life 总被引:1,自引:0,他引:1
Christopher?PetersonEmail author Nansook?Park Martin?E.?P.?Seligman 《Journal of Happiness Studies》2005,6(1):25-41
Different orientations to happiness and their association with life satisfaction were investigated with 845 adults responding to Internet surveys. We measured life satisfaction and the endorsement of three different ways to be happy through pleasure, through engagement, and through meaning. Each of these three orientations individually predicted life satisfaction. People simultaneously low on all three orientations reported especially low life satisfaction. These findings point the way toward a distinction between the full life and the empty life. 相似文献

Positive psychology has flourished in the last 5 years. The authors review recent developments in the field, including books, meetings, courses, and conferences. They also discuss the newly created classification of character strengths and virtues, a positive complement to the various editions of the Diagnostic and Statistical Manual of Mental Disorders (e. g., American Psychiatric Association, 1994), and present some cross-cultural findings that suggest a surprising ubiquity of strengths and virtues. Finally, the authors focus on psychological interventions that increase individual happiness. In a 6-group, random-assignment, placebo-controlled Internet study, the authors tested 5 purported happiness interventions and 1 plausible control exercise. They found that 3 of the interventions lastingly increased happiness and decreased depressive symptoms. Positive interventions can supplement traditional interventions that relieve suffering and may someday be the practical legacy of positive psychology. 相似文献

Student workers are largely understudied in organizational research, yet they represent an important part of the workforce. Their numbers are expected to rise as tuition continues to increase, and many adult workers are returning to school. The current study utilizes a person-centric approach to investigate latent patterns of work–school conflict (WSC) and work–school facilitation (WSF) as well as the antecedent (i.e., supervisor work–school support) and outcomes (i.e., job satisfaction, well-being, and school outcomes) tied to these latent patterns across school weeks. In a pilot study (n = 178 student workers), we first confirmed whether classes of WSC and WSF could be identified using latent profile analysis. Then, using 347 weekly WSC and WSF experiences, multilevel latent profile analysis identified four distinct profiles of WSC and WSF at the week level. Also, this modeling demonstrated that individuals tend to fluctuate between at least two profiles across weeks. Supervisor work–school support was found to predict weekly profile membership. Furthermore, the week-level profiles exhibited distinct relations with weekly outcomes (i.e., job satisfaction, well-being, and school preparedness). The results provide important theoretical and practical insights into the joint experience of interrole conflict and facilitation among student workers. 相似文献
