Cognitive perspectives on gambling propose that biased thinking plays a significant role in sustaining gambling participation and, in vulnerable individuals, gambling problems. One prominent set of cognitive biases include illusions of control involving beliefs that it is possible to influence random gaming events. Sociologists have reported that (some) gamblers believe that it is possible to throw dice in different ways to achieve gaming outcomes (e.g., ‘dice-setting’ in craps). However, experimental demonstrations of these phenomena are lacking. Here, we asked regular gamblers to roll a computer-simulated, but fair, 6 sided die for monetary prizes. Gamblers allowed the die to roll for longer when attempting to win higher value bets, and when attempting to hit high winning numbers. This behaviour was exaggerated in gamblers motivated to keep gambling following the experience of almost-winning in gambling games. These results suggest that gambling cognitive biases find expression in the motor behaviour of rolling dice for monetary prizes, possibly reflecting embodied substrates. 相似文献

Pollen specialization by solitary bees in an urban landscape 总被引:1,自引:1,他引:0
Many polylectic bee species are known to specialize locally on one or a few pollen types to increase foraging efficiency. What is relatively unknown is how different landscapes influence foraging decisions, and whether habitat alteration, such as that resulting from urbanization, influences broad-scale foraging activities of bees. This study evaluates the type and diversity of pollen collected by two solitary bees that are common in Toronto, Ontario, Canada, the native Osmia pumila and the exotic O. caerulescens, sampled in trap nests set up in urban parks and gardens. We found that the dominant pollen in every successful brood cell was either of one widespread, cosmopolitan lawn-invasive plant species (Trifolium repens) or one of two wind-pollinated tree genera (Quercus spp. and Betula spp.). In combination, these three represented more than 90 % of all pollen collected by each bee species. Despite considerable overlap in the dominant pollen types collected by each bee species, the exotic O. caerulescens was significantly more specialized than the native O. pumila. Brood cells with Betula as the dominant pollen type were more pollen species-rich than those cells having Trifolium or Quercus as dominant, perhaps a result of the comparatively low protein content in Betula pollen. 相似文献

The percentage of female-headed African American families has increased significantly since the 1960s. It is now estimated that over half of all African American children will grow up in a female-headed household. This article examines factors related to the formation of these households as well as the challenges associated with these households. Policies and programs that have been implemented to treat these families are examined. 相似文献

In this study, we examined possible gender differences in reasons for faculty attrition during the last 20 years at a small women's liberal arts college. The attrition rate was calculated from archival data collected through old college directories. As in earlier studies, the attrition rate was higher for women (31%) than for men (18.5%). Reasons for leaving the college were assessed in an online survey completed by 45 out of 66 tenure-track or tenured professors who left (excluding retirees). Work–family conflict was the most frequently cited reason for leaving, with disproportionately more women than men giving this reason. Open-ended responses revealed that work–family conflict typically referred to the difficulty of coordinating two careers. Female faculty who left were also significantly more dissatisfied than males with the support for balancing work and family life at the college. The need for colleges to create spousal policies to help faculty coordinate dual careers was discussed. 相似文献

This investigation sought to elaborate Koerner and Fitzpatrick’s theory of family communication by testing two theoretical models of family communication patterns (FCP), child-to-parent inclusion of the other in the self (IOS), and relational maintenance. Participants included 374 young adults recruited from two universities in different regions of the United States. Results best supported a model positioning maintenance as a mediator of the association between FCP and IOS, as compared to an alternative model with IOS as a mediator of the association between FCP and maintenance. These findings extend Koerner and Fitzpatrick’s theory by highlighting communication as the means by which overarching family schemas influence relationship-specific schemas; additionally, they commend the self-expansion model as a useful theoretical approach to relational maintenance behavior in family contexts. 相似文献

The objective of this study was to measure the relationships between online sexual compulsivity, three dimensions of dissociation (absorption, depersonalization, and amnesia), and past child abuse among men who have sex with men (MSM). A total of 517 MSM, recruited from Internet chat rooms, completed the survey. Results indicated that past child abuse was significantly related to dissociation but not online sexual compulsivity. It was also found that the amount of time MSM spent online in a one-week period, in general and specifically engaged in sexual activity, was significantly related to online sexual compulsivity and three dimensions of dissociation. Online sexual compulsivity was a significant predictor of absorption, depersonalization, and amnesia. Implications for clinicians and future research are presented. 相似文献

Research has shown that lesbian and gay (LG) individuals are coming out not only to their parents, but also to their siblings. Eighty percent of individuals in the United States are raised with one or more siblings; however, researchers have frequently underestimated the importance of the sibling bond. This study examined potential correlates of heterosexual siblings’ acceptance of their LG sister or brother using an online survey format (N = 189). In addition, psychometric properties for the Acceptance of Sibling Sexual Orientation Scale are provided. Results revealed that greater sibling relationship quality in adulthood, more contact with LG individuals, greater knowledge of LG communities, more support for LG civil rights, and various demographics (being female, having higher educational levels, not having an orthodox/fundamentalist religious orientation, less church attendance, and more liberal political ideology) are related to heterosexual siblings’ acceptance of their LG sister or brother. However, when these variables were examined together in a regression model, only sibling relationship in adulthood, contact with LG individuals, support for LG civil rights, and religious attendance were significant unique predictors of acceptance. 相似文献

The development of one's sexual minority identity is often stunted by a heterosexist society. For individuals with multiple minority oppressions, this process becomes even more complicated. As such, there has been a call among researchers for more empirical research on the experiences of lesbian, gay, bisexual (LGB) individuals from racial/ethnic minority groups. This study uses qualitative methods to fill gaps in the literature related to identity development among same-gender attracted Middle Eastern/Arab individuals living in the United States. From 12 interviews, 13 themes associated with intersectionality, race/ethnicity, sexual identity development, discrimination, stigma, oppression, and invisibility. Themes, subthemes, and their implications are discussed. 相似文献

This paper examines whether receipt of public or private assistance is associated with recipients’ own generosity in the form of formal and informal volunteering. Using matched data from the 2007–2011 American Time Use Survey and the Annual Social and Economic Supplement to the Current Population Survey, this paper finds that receipt of private assistance from friends and relatives is negatively associated with the time women spend caring for non-household adults and the time men spend caring for non-household children. Receipt of public assistance is found to be negatively associated with men’s care of non-household adults. No associations are found between either type of assistance and time spent volunteering for a formal organization. 相似文献

The authors of this article are two teacher educators who worked collaboratively to co-teach an interdisciplinary English and US history class to eleventh-grade students in an urban high school. They wanted to ensure the methods they were teaching preservice teachers were current and effective. The article discusses the foundational beliefs that influenced their teaching, the interdisciplinary curriculum they taught, some of the challenges they encountered, and a brief snapshot of the students' views of the curriculum. The authors discuss that putting their beliefs into practice outweighed the challenges they encountered—a culturally relevant, authentic, interdisciplinary curriculum can be effective in an urban classroom. The experience also assisted them in teaching their English and social studies methods classes. 相似文献
