We report two experiments designed to investigate the potential use of vibrotactile warning signals to present spatial information to car drivers. Participants performed an attention-demanding rapid serial visual presentation (RSVP) monitoring task. Meanwhile, whenever they felt a vibrotactile stimulus presented on either their front or back, they had to check the front and the rearview mirror for the rapid approach of a car, and brake or accelerate accordingly. We investigated whether speeded responses to potential emergency driving situations could be facilitated by the presentation of spatially-predictive (80% valid; Experiment 1) or spatially-nonpredictive (50% valid; Experiment 2) vibrotactile cues. Participants responded significantly more rapidly following both spatially-predictive and spatially-nonpredictive vibrotactile cues from the same rather than the opposite direction as the critical driving events. These results highlight the potential utility of vibrotactile warning signals in automobile interface design for directing a driver’s visual attention to time-critical events or information. 相似文献

Current research is yielding an increasingly heterogeneous picture of suicide seasonalities: They seem to depend on methods and, moreover, they seem to have smoothed in recent decades. This work examines the latter issue by comparing suicide seasonalities in the canton of Zurich, Switzerland, in the 16 th -18 th centuries, 1901-1920 and 1969-94. The results indicate shifts of peaks and lows on suicide seasonalities over the centuries, with a smoothing of seasonalities toward the 21 th century. The recent period does not show any suicide seasonality at all. The canton of Zurich seems to be ahead of the general trend found in other regions of Switzerland. 相似文献

Social Change: Toward an Informed and Critical Understanding of Social Justice and the Capabilities Approach in Community Psychology 下载免费PDF全文
Felix Munger Tim MacLeod Colleen Loomis 《American journal of community psychology》2016,57(1-2):171-180
Community psychology has long been concerned with social justice. However, deployments of this term are often vague and undertheorized. To address this weakness in the field's knowledge body we explored John Rawls's theory of social justice and Amartya Sen's economic theory of the capabilities approach and evaluated each for its applicability to community psychology theory, research, and action. Our unpacking of the philosophical and political underpinnings of Rawlsian theory of social justice resulted in identifying characteristics that limit the theory's utility in community psychology, particularly in its implications for action. Our analysis of the capability approach proposed by Amartya Sen revealed a framework that operationalizes social justice in both research and action, and we elaborate on this point. Going beyond benefits to community psychology in adopting the capabilities approach, we posit a bi‐directional relationship and discuss how community psychology might also contribute to the capabilities approach. We conclude by suggesting that community psychology could benefit from a manifesto or proclamation that provides a historical background of social justice and critiques the focus on the economic, sociological, and philosophical theories that inform present‐day conceptualizations (and lack thereof) of social justice for community psychology. 相似文献

A wide range of research suggests that the exertion of self-control is a limited resource or constrained by a motivational shift. Less attention, however, has been given to the question how self-control capacity can be restored. This study examined whether this restoration can be achieved by “presence,” the perceptual illusion of non-mediation. We suggest that the adoption of the mediated reference systems creates a “holiday from self” and restores self-control capacity. Depleted participants who saw an immersive video clip performed better in a subsequent self-control task than participants who saw a non-immersive video clip or were in a waiting group. But the concrete mechanism remains open: Self reported presence did not serve as a mediator. 相似文献

Escalation of commitment denotes decision makers' increased reinvestment of resources in a losing course of action. Despite the relevance of this topic, little is known about how information is processed in escalation situations, that is, whether decision makers who receive negative outcome feedback on their initial decision search for and/or process information biasedly and whether these biases contribute to escalating commitment. Contrary to a widely cited study by E. J. Conlon and J. M. Parks (1987), in 3 experiments, the authors found that biases do not occur on the level of information search. Neither in a direct replication and extension of the original study with largely increased test power (Experiment 1) nor under methodologically improved conditions (Experiments 2 and 3) did decision makers responsible for failure differ from nonresponsible decision makers with regards to information search, and no selective search for information supporting the initial decision or voting for further reinvestment was observed. However, Experiments 3 and 4 show that the evaluation of the previously sought information is biased among participants who were responsible for initiating the course of action. Mediation analyses show that this evaluation bias in favor of reinvestment partially mediated the responsibility effect on escalation of commitment. 相似文献

科学修辞的认知意义在理论上基于对知识和修辞的不同认识,即知识被认为是拥有确定性的真的信念,修辞的论辩、逻辑部分被重新发掘。在这一框架下,修辞不再外在于科学知识核心,而是在从个人经验到科学假说、直至科学理论及其检验等一系列过程中都有着深刻的认知意义。 相似文献

服务型政府作为一种基于公民本位、崇尚服务理念、追求公共利益的现代政府模式,近年来逐渐成为我国政府改革中的热门话语。服务型政府的建设是一个综合性课题,在委托代理理论、新公共管理、新公共服务和公共治理理论的基石上,为了更好地实现公正与平等、效率与竞争、廉洁与透明、民主与参与等公共价值,建设法治政府、有限政府、责任政府、回应型政府和企业型政府成了必然的路径选择,这亦是实现善治的必然逻辑。 相似文献

Groups perform better than the best individuals on letters-to-numbers problems: informative equations and effective strategies 总被引:1,自引:0,他引:1
Laughlin PR Zander ML Knievel EM Tan TK 《Journal of personality and social psychology》2003,85(4):684-694
One-hundred 3-person groups and 300 individuals solved 2 letters-to-numbers problems, requiring identification of the coding of 10 letters to 10 numbers by proposing an equation in letters, receiving the answer in letters, proposing a hypothesis, and receiving feedback on the hypothesis on each trial. There were 5 instruction conditions: (a). standard, (b). use at least 3 letters on all equations, (c). use at least 4 letters on all equations, (d). number 1 known before beginning problem, and (e). number 9 known before beginning problem. The groups had fewer trials to solution, proposed more complex equations, and identified more letters per equation than the best individuals. Performance was best under instructions to use at least 4 letters and with the number 9 known. 相似文献
