When compared with other demographics, young males are more likely to take a variety of risks (like skateboarding, using drugs) and use risky behaviors to attract romantic partners. This study extended research on risk by assessing the attractiveness of 101 different kinds of risks performed by males and females. As predicted, factor analysis revealed that the attractiveness of diverse risks clustered around two major dimensions: risks like those faced by hunter‐gatherer humans (e.g., handling fire and dangerous animals) and risks that are uniquely modern (e.g., driving without seat belts). Additionally, results confirmed that modern risks were rated as unattractive for both sexes, whereas hunter‐gatherer risks were rated as especially attractive when performed by males. Discussion focuses on cultural and evolutionary explanations for the link between risk and attractiveness. 相似文献
Is identity an important predictor of social behavior? The present longitudinal study is focused on identity in order to understand why people continue to volunteer over an extended period of time. The theory of planned behavior and the role identity model of volunteering are used as theoretical framework. Two hundred thirty Italian volunteers were sampled and followed for 3 years. We analyzed functions of role identity as a volunteer. Results showed a significant impact of role identity in predicting volunteer performance after 3 years, mediated through behavioral intentions. Role identity fully mediated the relationships between behavioral intention and attitude, social norms, past behavior and parental modelling. 相似文献
It was hypothesized that character strengths relate to job performance. Both constructs were investigated with respect to their currently known dimensions (i.e., 24 character strengths; job performance: task performance, job dedication, interpersonal facilitation, organizational support) to get a comprehensive overview of their co-occurrence. Two samples, 318 and 108 employees, respectively, filled in measures assessing character strengths as traits and their usefulness at work, and the job performance dimensions. For Sample 2, also supervisors judged the employees’ job performance. Based on this set of two samples we show replicable associations between character strengths and job performance (self-reports and supervisory ratings). Furthermore, the number of individual strengths beneficial at work was related to job performance. These promising findings open a new field for research on human performance. 相似文献
Cancer is now the biggest cause of mortality worldwide. Although the debilitating physical symptoms of cancer have long been known, the psychological and social impacts of cancer have become the subject of examination only relatively recently. The psychological outcomes that have been examined are primarily negative emotional variables, e.g., anxiety, but emerging research has focused on positive emotional variables, e.g., post‐traumatic growth, or cognitive outcomes. In this article, we provide a synthesis of reviews that have addressed the psychosocial impact of cancer. The framework for this synthesis is provided by a conceptualisation in which the presence of cancer impacts on psychosocial outcomes either directly or via mediating variables, including physical symptoms and treatment, and that this effect may be moderated by several variables, some characteristic of the person with cancer (demographic or personality‐related variables) and some characteristic of their environment (social support and medical variables). We also briefly examine the impact of cancer on the broader family unit following cancer diagnosis, treatment, survivorship and bereavement. We conclude that the heterogeneity of the cancer experience highlights the need for theoretically driven research and consistency in measurement approaches to determine mechanisms by which cancer exerts influence on psychosocial outcomes. This would allow development and delivery of targeted psychological interventions and a clearer delineation of the roles of the various parties, including clinical psychologists, family members and policymakers. 相似文献

The huge impact of technology on people and institutions cannot be denied. More than often, this influence seems to have negative effects on them. However, the proposal of Social Change and Human Behavior Influence for impact brings some new light on this issue: What if society were to enable its members to attain their desired goals by means of the creation and use some technology that made it possible? The central argument of this book is: humankind can take a qualitative leap to nurture people’s quality of life, and thus arrive at a state of Augmented Humanity (AH), if all humans were to understand that individual well-being is the cause and consequence of collective well-being. And technology can contribute to the realization of the AH, if those who design and use it do justice to their own capacity for generosity, compassion, honesty and courage.
This study investigated the orienting of visual attention in rats using a 3-hole nose-poke task analogous to Posner, Information processing in cognition: the Loyola Symposium, Erlbaum, Hillsdale, (1980) covert attention task for humans. The effects of non-predictive (50% valid and 50% invalid) and predictive (80% valid and 20% invalid) peripheral visual cues on reaction times and response accuracy to a target stimulus, using Stimuli-Onset Asynchronies (SOAs) varying between 200 and 1,200 ms, were investigated. The results showed shorter reaction times in valid trials relative to invalid trials for both subjects trained in the non-predictive and predictive conditions, particularly when the SOAs were 200 and 400 ms. However, the magnitude of this validity effect was significantly greater for subjects exposed to predictive cues, when the SOA was 800 ms. Subjects exposed to invalid predictive cues exhibited an increase in omission errors relative to subjects exposed to invalid non-predictive cues. In contrast, valid cues reduced the proportion of omission errors for subjects trained in the predictive condition relative to subjects trained in the non-predictive condition. These results are congruent with those usually reported for humans and indicate that, in addition to the exogenous capture of attention promoted by both predictive and non-predictive peripheral cues, rats exposed to predictive cues engaged an additional slower process equivalent to human's endogenous orienting of attention. To our knowledge, this is the first demonstration of an endogenous-like process of covert orienting of visual attention in rats. 相似文献
