This study analyzed the relationships between decision time, subjective probability, and task difficulty in the context of a probability assessment task involving memory search. The results indicate that decision time and subjective probability do not yield identical functions. Also, decision time increases as subjective task difficulty increases. A similar relationship obtains between decision time and a measure of objective task difficulty. These latter two findings are inconsistent with Hogarth’s (1975) prediction of a nonmonotonic relationship between decision time and task difficulty.  相似文献

This study explored the effects of a social studies peer-teaching intervention on student perceptions of class environment, adjustment, and academic performance. There were 45 students in the experimental group (E) and 46 controls (C) from four fifth-grade classes in a suburban, predominantly white, middle-class school. The Classroom Environment Scale (CES) and a School Opinion Survey were used to assess student views of the classroom. Students completed self-esteem and peer sociometric rating measures and teachers submitted adjustment ratings for all pupils. Report card and average monthly grades were recorded in social studies. After the intervention, Es compared to Cs came to see their classes as more Involved, Orderly and Organized, and Competitive, and reported being happier in class and enjoying aspects of their school work more. The groups did not differ in change in self-esteem. Both groups improved directionally in peer liking, though Cs did so more than Es. Teachers rated Es as having increased competence and decreased in problems after the program. Es did significantly better than Cs both on report cards and monthly social studies grades due primarily to the substantial improvement of Es with initially low academic status.  相似文献

Protection motivation theory and the extended parallel processing model are used to predict the motivational impact of information regarding a genetic susceptibility to heart disease. One hundred ninety-eight smokers read 1 of 3 vignettes: gene positive, gene negative, or standard smoking risk information. Analyses examined whether the impact of type of risk information was moderated by smokers' self-efficacy (SE) levels. Key outcomes were intention to quit and intention to attend an information session about quitting. There were significant main effects of SE and of receiving gene-positive risk information on intentions to quit. There was a significant Risk x SE interaction on intentions to attend an information session. SE was not associated with intentions to attend the information session for smokers in the gene-positive group. Intentions to attend the session were negatively associated with SE for smokers in the lower risk groups. Implications for using genetic risk information to motivate smoking cessation are discussed.  相似文献

The reported study used the dual-task methodology to assess the attention demands associated with high and low contextual interference (CI) practice environments. Two specific issues were addressed. First, is there a difference in the attention demands during random and blocked schedules of practice? Second, what is the time course of any differential attention demands that emerge during random and blocked training? In order to address these questions two specific temporal loci were probed during practice: a pre-response interval and the inter-trial interval. It was assumed that the pre-response interval contained the reconstructive activity that is central to the reconstruction position. In contrast, the inter-trial interval has been interpreted in previous work to be the interval in which critical intra- and inter-item processing is performed during random practice. The data revealed a typical CI effect for the primary key-pressing task. Specifically , blocked-practice participants displayed superior performance during training but performed less well than the random-practice individuals at the time of retention. The poorer acquisition performance of the random practice participants was associated with higher cognitive demand during both the pre-response and the inter-trial intervals than that of individuals assigned to blocked practice. The greater attention demands for random-practice individuals are discussed with respect to processes that might occur in both the pre-response and the inter-trial intervals.  相似文献

An ongoing study of government raids on minority religious communities in 19 Western‐style democracies over seven‐plus decades shows a dramatic increase in raids beginning in the 1990s. Two distinct and related patterns are found to explain this escalation in frequency. Both patterns involved countermovement mobilization by coalitions of oppositional groups that effectively framed new or nontraditional religious movements (NRMs) as threats to their own members and the larger society, thereby prompting state actions of social control. The patterns are distinguished by a new relationship of countermovement actors to the state. In one pattern, we found the development of a transnational network forging a common collective action frame, movement ideology, and organizational strategy. Seizing political opportunities in the wake of increasing concerns regarding child endangerment, countermovement actors targeted NRMs as harbingers of child abuse and pressed authorities to take action. In the second pattern, we found a concentration of raids in one country (France). Here, the oppositional networks were not simply third‐party interest groups but were fully integrated into the state apparatus, hence awarded power and given extraordinary influence. Consequently, state raids increased exponentially. The study also provides five years of new data from a previous report examining their impact on the larger set of findings and identifying new trends.  相似文献

Although the United States is clearly still reeling from its current and recent exported wars, it has never gotten close enough to fully witness their actual horror. As a result, the nation's profound identification with the archetypes of the warrior and hero has never undergone a corrective experience. The country's one-sided myth of its own exceptionalism and goodness has created not only an unattainable image to live up to, but also its flip side—a very repressed and ignored shadow, which is liable to pop up in highly unregulated forms. The psychic split this creates is now being played out in a deeply divided nation and the seemingly sudden emergence of a president who carries all the shadow aspects of the hero archetype. The United States is certainly not the only nation with a narrative elevating itself above all others—or that has ended up enthroning its own shadow. But because of its size and power, the consequences are much more damaging. It would serve the United States well to relativize its view of itself, and for it to take a more appropriate place among the nations of this world. However, history shows that this kind of shift does not happen voluntarily; instead it is forced upon a country by its own failure. It remains to be seen if the United States will be able to make the necessary leap in consciousness to avoid following in history's footsteps.  相似文献

Insomnia is highly prevalent among active-duty military service members. Cognitive Behavioral Therapy for Insomnia (CBT-I) is a well-established and effective treatment; however, research and treatment recommendations have primarily focused on civilian or veteran populations. A multitude of military-specific factors directly impact service members’ sleep and the subsequent treatment recommendations. This article provides treatment considerations for the use of CBT-I with active-duty U.S. Army personnel. First, an overview of the theoretical model of insomnia, including military-specific predisposing, precipitating, and perpetuating factors, is presented, followed by a review of common comorbid conditions among service members with insomnia. Finally, discussion focuses on considerations and strategies for implementing components of CBT-I with service members, managing sleep during deployments, and adjusting sleep to accommodate overnight duties. Additional training resources and supplemental video examples (with actors) are provided.  相似文献
