The present study compared the number of severe life events and chronic adversities as reported retrospectively by mothers
of children with an anxiety disorder (n = 39) prior to the onset of their most recent episode, with controls (n = 39) matched for age and sex. The parent version of the Psychosocial Assessment of Childhood Experiences (PACE) was used
to assess chronic adversities (long-term experiences with negative impact on child) and severe life events (discrete life
events with high long-term threat). A significantly greater number of severe life events and chronic adversities were assessed
prior to onset for anxious children compared to controls. The finding for severe life events held regardless of whether impact
ratings were assigned by mothers or a panel of independent raters, suggesting the findings reflect actual as opposed to perceived
differences. Results suggest that both discrete and chronic stressors may constitute risk for future episodes of anxiety in
children.

The information content of panoramic images II: view-based navigation in nonrectangular experimental arenas 总被引:2,自引:0,他引:2
Cheung A Stürzl W Zeil J Cheng K 《Journal of experimental psychology. Animal behavior processes》2008,34(1):15-30
Two recent studies testing navigation of rats in swimming pools have posed problems for any account of the use of purely geometric properties of space in navigation (M. Graham, M. A. Good, A. McGregor, & J. M. Pearce, 2006; J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, 2004). The authors simulated 1 experiment from each study in a virtual reality environment to test whether experimental results could be explained by view-based navigation. The authors recorded a reference image at the target location and then determined global panoramic image differences between this image and images taken at regularly spaced locations throughout the arena. A formal model, in which an agent attempts to minimize image differences between the reference image and current views, generated trajectories that could be compared with the search performance of rats. For both experiments, this model mimics many aspects of rat behavior. View-based navigation provides a sufficient and parsimonious explanation for a range of navigational behaviors of rats under these experimental conditions. 相似文献

Much of the debate about the ethics of enhancement has proceeded according to two framing assumptions. The first is that although enhancement carries large social risks, the chief benefits of enhancement are to those who are enhanced (or their parents, in the case of enhancing the traits of children). The second is that, because we now understand the wrongs of state-driven eugenics, enhancements, at least in liberal societies, will be personal goods, chosen or not chosen in a market for enhancement services. This article argues that both framing assumptions must be rejected, once it is understood that some enhancements--especially those that are most likely to garner resources and become widespread--will increase human productivity. Once one appreciates the productivity-increasing potential of enhancements, one can begin to see that enhancement need not be primarily a zero sum affair, that the social costs of forgoing enhancements may be great, and that the state may well take an interest in facilitating biomedical enhancements, just as it does in facilitating education and other productivity-increasing traditional enhancements. Appreciating the productivity-increasing potential of enhancements also makes it possible to view the enhancement debate in a new light, through the lens of the ethics of development. 相似文献

Intersectional Identities and the Politics of Altruistic Care in a Low-Income, Urban Community 总被引:1,自引:0,他引:1

The literatures on the ways in which social identity and social position (e.g., gender, class, race) inform altruism have developed orthogonally. In this community-based qualitative study we use intersectionality theory to explore the complex ways in which social identity and social structures jointly influence altruism among African American adults (n?=?40) in an urban, economically distressed housing community in New York City. Content analysis of participants’ narratives reveals the ways in which gender, race, ethnicity, class, age, and urbanicity work in tandem to create differential patterns of vulnerability, differential needs, differential commitments to caring for particular subgroups, and informs how altruists are perceived by others. The implications of this work for future research on altruism are highlighted. 相似文献

Our research examines whether intersecting racial and gender identities affect person perception. Predominantly White undergraduates (292) from a large northeastern U.S. university categorized and rated pictures (Study 1) and videos (Study 2) of Black and White men and women. We supported three hypotheses: 1) intersectionality affects person perception processes, leading to gender categorization errors for Black women; 2) “Blackness” and “maleness” are highly associated for Black male and female targets; and, 3) women are perceived as unattractive proportionally to their perceived masculinity, leading Black women to be rated as less attractive than other women. We suggest that intersectional approaches are required in order to fully understand person perception. Further, the Black/male association may lead to unique harms for Black women. 相似文献
