Social connections are essential to health and well‐being. However, when pursing social acceptance, people may sometimes engage in behavior that is detrimental to their health. Using a multi‐time‐point design, we examined whether the structure of an emerging network of students in an academic summer school program correlated with their physical health and mental well‐being. Participants who were more central in the network typically experienced greater symptoms of illness (e.g., cold/flu symptoms), engaged in riskier health behaviors (e.g., binge drinking), and had higher physiological reactivity to a stressor. At the same time, they were happier, felt more efficacious, and perceived less stress in response to a strenuous math task. These outcomes suggest that social ties in an emerging network are associated with better mental well‐being, but also with poorer physical health and health behaviors.

Mark Jago has presented a dilemma for truthmaker non-maximalism—the thesis that some but not all truths require truthmakers. The dilemma arises because some truths that do not require truthmakers by the non-maximalist’s lights (e.g., that Santa Claus does not exist) are necessitated by truths that do (e.g., that Barack Obama knows that Santa Claus does not exist). According to Jago, the non-maximalist can supply a truthmaker for such a truth only by conceding the primary motivation for the view: that it allows one to avoid positing strange ‘negative’ entities without adopting a non-standard account of the necessary features of ordinary things. In this paper, I sketch out and defend two plausible non-maximalist proposals that evade Jago’s dilemma.  相似文献

The relationship between emotion and motor action has been previously examined using relatively simple motor tasks. However, there has been limited research using more complex physical tasks. One such complex physical task is high-angle climbing. In this experiment, we examined the performance of climbers in a dual climbing and word memory task, in which they were asked to recall fear-related or neutral words after the climb, as well as single-task performance. Climbing distance, efficiency, and word recall all significantly decreased in the dual-task conditions, relative to the single tasks. Climbing distance and efficiency also decreased in the fear word dual task, relative to the neutral word memory dual task. Subjective measures of performance indicated that climbers were aware of impaired climbing performance in the dual tasks, relative to the climbing-only condition, but that they were not aware of the increased impairment caused by the fear words. These findings have important theoretical and practical implications, particularly in occupational settings requiring climbing-like operations, such as fire-fighting and search and rescue.  相似文献

In a series of four experiments, we examined the impact of disfluency in multimedia learning by testing contrasting predictions derived from disfluency theory and cognitive load theory against each other. Would a less legible text be beneficial to learning when accompanied by pictures, and what would be the role of less legible pictures? Students (N = 308) learned with text and pictures that were either easy‐to‐read (i.e., fluent) or harder‐to‐read (i.e., disfluent) about how a toilet flush works (Experiments 1–3) and about how lightning develops (Experiment 4). In line with disfluency theory, a disfluent text led to better performance in the transfer test and to more invested mental effort in Experiment 1. However, these beneficial effects could not be replicated in Experiments 2, 3, and 4, leaving open questions regarding the stability and generalizability of the disfluency effect, and thus raising concerns regarding its impact for educational practice.

The First World War forced the Russian intelligentsia to rethink its values—values that had been constructed in the nineteenth century. Distancing itself from pacifism and cultural relativism, it began to search for a moral meaning to the war that broke out in 1914—i.e. to defend the war as morally right and having a higher spiritual purpose. Russian philosophers were central to these debates, as they tried to interpret the war, and the relationship between war and peace, from a metaphysical point of view. The paper will look at philosophical, ethical and religious aspects of these debates, and some of the philosophers who participated in them.  相似文献

We investigate the relationship between supervisors’ irritation and follower perceptions of abusive supervision. Based on the integrated self‐control framework, we propose a positive relationship between supervisor irritation and abusive supervision. Moreover, we propose this relationship to be buffered by supervisors’ self‐control capacities and by external monitoring of the supervisor by upper management. We tested our hypotheses in a two‐source survey study with 96 supervisor‐follower dyads. Our results show a positive relationship between supervisor irritation and abusive supervision and an interaction between supervisor irritation and supervisor self‐control. The interaction pattern revealed a positive relationship between supervisor irritation and abusive supervision if supervisor self‐control is low. We also found an interaction between supervisor irritation and external monitoring in predicting active but not passive forms of abusive supervision. Our findings underline the role of self‐control processes in explaining abusive supervision.  相似文献

Many couples tend to report steadily decreasing relationship quality following the birth of a child. However, little is known about the postpartum period for Latino couples, a rapidly growing ethnic group who are notably underserved by mental and physical health caregivers in the United States. Thus, this study investigated whether a brief couples’ intervention focused on helping couples support each other while increasing healthy behaviors might improve dyadic functioning postpartum. This study presents secondary analyses of data regarding couple functioning from a larger randomized controlled trial with 348 Latino couples to promote smoking cessation. Portions of the intervention taught the couple communication and problem‐solving skills to increase healthy behavior. Couples participated in four face‐to‐face assessments across 1 year starting at the end of the first trimester. Latent growth curve analyses revealed that the treatment group reported an increase in relationship satisfaction and constructive communication after the intervention, which diminished by 1‐year follow‐up, returning couples to their baseline levels of satisfaction. Results suggest that incorporating a brief couple intervention as part of a larger health intervention for Latinos may prevent postpartum decreases in relationship satisfaction.  相似文献

Methods to determine the direction of a regression line, that is, to determine the direction of dependence in reversible linear regression models (e.g., xy vs. yx), have experienced rapid development within the last decade. However, previous research largely rested on the assumption that the true predictor is measured without measurement error. The present paper extends the direction dependence principle to measurement error models. First, we discuss asymmetric representations of the reliability coefficient in terms of higher moments of variables and the attenuation of skewness and excess kurtosis due to measurement error. Second, we identify conditions where direction dependence decisions are biased due to measurement error and suggest method of moments (MOM) estimation as a remedy. Third, we address data situations in which the true outcome exhibits both regression and measurement error, and propose a sensitivity analysis approach to determining the robustness of direction dependence decisions against unreliably measured outcomes. Monte Carlo simulations were performed to assess the performance of MOM-based direction dependence measures and their robustness to violated measurement error assumptions (i.e., non-independence and non-normality). An empirical example from subjective well-being research is presented. The plausibility of model assumptions and links to modern causal inference methods for observational data are discussed.  相似文献
