Personality change is emerging as an important predictor of health and well‐being. Extending previous research, we examined whether two types of personality change, directional and absolute, are associated with both subjective and objective indicators of health. Utilizing the longitudinal Midlife in the United States survey (MIDUS) data, we examined whether both types of change over 10 years were associated with psychological well‐being, self‐reported global health, and the presence of metabolic syndrome (MetS) components and diagnosis. Socially undesirable personality change (e.g., becoming less conscientious and more neurotic) and absolute personality change were independently associated with worse perceived health and well‐being at Time 2. Notably, absolute personality change, regardless of the direction, was also associated with having a greater number of MetS components and a greater probability of diagnosis at Time 2. In sum, too much personality change may be bad for one's health: Socially undesirable and absolute personality change were both associated with worse psychological health and worse metabolic profiles over 10 years. These findings suggest that personality change may contribute to psychological and physical health, and provide initial insight into potential intermediate links between personality change and distal outcomes such as mortality. 相似文献

Even though it is unlawful to send chain letters through the mails, thousands of Americans send them to friends, acquaintances, and strangers in hopes that their names will move to the top of the pyramid, and they will receive the influx of tax‐free dollars from those at the bottom of the chain. This paper analyzes the content and structure of the chain letter and also describes the accounts which chain letter players (N=129) provide for their participation. Differences between male and female accounts and participation strategies are provided. The implications for these differences for understanding participation in the underground economy are discussed. 相似文献

Groups of subjects watched films under two conditions of density (high and low) and number (large and small groups). After one film a confederate applauded and the reactions of the audience were observed. As predicted by an analysis based on the intensification theory of crowding, high density greatly increased the contagion of the applause, Larger numbers also had a significant, though considerably smaller effect on contagion. The findings indicate that relatively simple environmental factors such as density and number may be major determinants of whether contagion occurs in groups. 相似文献

The earth cannot support humanity's increasing population and consumption. Concerned scientists and citizens are therefore wondering how we might work toward a sustainable, survivable human future. Sustainability involves increased technological efficiency and agricultural productivity, but also incentives and attitudes that moderate consumption. Social psychology contributes to changing attitudes and behavior with evidence that a) materialism exacts psychic as well as environmental costs, and b) economic growth has failed to improve human morale. Two principles-the adaptation level phenomenon and social comparison-help explain why materialism and increasing affluence fail to satisfy. 相似文献

Using data collected in 125 seventh-grade and 56 eighth-grade Texas classrooms in the context of the “Scaling Up SimCalc” research project in 2005–07, we examined relationships between teachers’ mathematics knowledge, teachers’ classroom decision making, and student achievement outcomes on topics of rate, proportionality, and linear function—three important and cognitively demanding prealgebra topics. We found that teachers’ mathematical knowledge was correlated with student achievement in only one study out of three. We also found a lack of correlations between teachers’ mathematical knowledge and critical aspects of instructional decision making. Curriculum and other learning resources (e.g., technology, student–student interactions) are clearly important factors for student learning in addition to, and in interaction with, teachers’ mathematical knowledge. Our results suggest that mathematics knowledge for teaching may have a nonlinear relationship with student learning, that those effects may be heavily mediated by other instructional factors, and that short-term content knowledge gains in teacher workshops may not persist in classroom instruction. We discuss a need in the field for richer models of how “mathematical knowledge for teaching” works in the context of complete instructional systems. 相似文献

Few studies have examined rates of mental health problems among special duty military personnel, who often have frequent deployments and high exposure to operational stressors and trauma. The current study examined the severity and rates of positive screening for posttraumatic stress, depression, and insomnia among 194 U.S. Air Force pararescuemen (PJs) in the active duty (AD) and National Guard/Reserve (NG/R) components. Overall estimated rates were 11.6% for probable posttraumatic stress disorder (PTSD), 1.6% for probable depression, and 16.1% for clinical insomnia. PJs in the NG/R reported significantly more severe posttraumatic stress symptoms (F(1, 162) = 10.031, p = .002, partial η2 = .058) and were approximately twice as likely to screen positive for probable PTSD (8.5% vs. 19.1%; χ2[1] = 3.679, p = .055). No differences in the rate or severity of depression or insomnia symptoms were found. Rates of positive screens are comparable to or lower than previously published rates among military personnel. 相似文献

Most epistemologists hold that knowledge entails belief. However, proponents of this claim rarely offer a positive argument in support of it. Rather, they tend to treat the view as obvious and assert that there are no convincing counterexamples. We find this strategy to be problematic. We do not find the standard view obvious, and moreover, we think there are cases in which it is intuitively plausible that a subject knows some proposition P without—or at least without determinately—believing that P. Accordingly, we present five plausible examples of knowledge without (determinate) belief, and we present empirical evidence suggesting that our intuitions about these scenarios are not atypical. 相似文献

This paper examines the first moments of the emergence of “psychometrics” as a discipline, using a history of the Binet–Simon test (precursor to the Stanford–Binet) to engage the question of how intelligence became a “psychological object.” To begin to answer this, we used a previously-unexamined set of French texts to highlight the negotiations and collaborations that led Alfred Binet (1857–1911) to identify “mental testing” as a research area worth pursuing. This included a long-standing rivalry with Désiré-Magloire Bourneville (1840–1909), who argued for decades that psychiatrists ought to be the professional arbiters of which children would be removed from the standard curriculum and referred to special education classes in asylums. In contrast, Binet sought to keep children in schools and conceived of a way for psychologists to do this. Supported by the Société libre de l'étude psychologique de l'enfant [Free society for the psychological study of the child], and by a number of collaborators and friends, he thus undertook to create a “metric” scale of intelligence—and the associated testing apparatus—to legitimize the role of psychologists in a to-that-point psychiatric domain: identifying and treating “the abnormal”. The result was a change in the earlier law requiring all healthy French children to attend school, between the ages of 6 and 13, to recognize instead that otherwise normal children sometimes need special help: they are “slow” (arriéré), but not “sick.” This conceptualization of intelligence was then carried forward, through the test's influence on Lewis Terman (1877–1956) and Lightner Witmer (1867–1956), to shape virtually all subsequent thinking about intelligence testing and its role in society. 相似文献
