Sexual assault perpetrated by men against women is a distressingly common occurrence, particularly on college campuses. One of the barriers to assault prevention efforts is the general perception of violence against women as an unwanted yet implicitly tolerated aspect of the status quo. Drawing on system justification theory, a concept used to explain why individuals accept aspects of their social systems that are objectively unjust, the mechanisms that perpetuate sexual assault are examined. Furthermore, this theory is used to examine current prevention efforts on college campuses and suggestions for modifications to these programs will be made.  相似文献

The federal regulations of human research were written to permit the use of discretion so that research can fit the circumstances under which it is conducted. For example, the researcher and institutional review board (IRB) could waive or alter some informed consent elements if they deem this the morally and scientifically best way to conduct the research. To do so, however, researchers and IRBs would first have to use mature moral and scientific judgment. They might also have to rely on empirical research to discover the most effective way to act on their moral sense (e.g., to discover how best to approach potential research participants and explain the nature and purpose of the research participation for which they are being recruited, to ensure comprehension and competent decision making). On discovering the most ethical way to proceed, they would then need to look to the federal regulations of human research to discover how to document their decision and justify it within that somewhat flexible regulatory structure. Unfortunately, many IRBs and researchers fail to take these sensible steps to solve ethical problems and proceed immediately to a default requirement of the regulations that places science at odds with the regulations and, ostensibly, with ethics. The following articles in this special issue are about the process of learning to engage in ethical problem solving and using the flexibility permitted by the federal regulations. These articles extricate researchers from the mindset that has gotten them into trouble, and, ideally, provoke them to use mature common sense and moral judgment.  相似文献

This study investigated the multigenerational impact of mothers’ own exposure to physical maltreatment on internalizing symptoms in her child after accounting for her parenting practices, depression, and the child’s own exposure to stressful life events. Children (n?=?101, ages 5–16), predominantly African American, were recruited into this cross sectional study using ethnographic mapping and targeted sampling for high-risk neighborhoods. Mothers reported retrospectively on their own exposure to physical maltreatment in childhood, their parenting practices, as well as current depressive symptoms. Maternal report of her child’s exposure to stressful life events and child behavior was also collected. Maternal childhood exposure to physical maltreatment was significantly associated with her child’s internalizing symptoms (p?=?.004); this effect remained after accounting for child sex, maternal depressive symptoms, harsh parenting practices, and the child’s own exposure to stressful life events. Formal tests of mediation through these pathways were non-significant. Findings suggest mothers’ experience of childhood maltreatment contributes uniquely to children’s internalizing symptoms, potentially through previously uncharacterized pathways. Examination of additional behavioral, psychosocial and biological pathways may help better describe the multi-generational effects of child maltreatment.  相似文献

The framework of plateaus, dips, and leaps shines light on periods when individuals may be inventing new methods of skilled performance. We begin with a review of the role performance plateaus have played in (a) experimental psychology, (b) human–computer interaction, and (c) cognitive science. We then reanalyze two classic studies of individual performance to show plateaus and dips which resulted in performance leaps. For a third study, we show how the statistical methods of Changepoint Analysis plus a few simple heuristics may direct our focus to periods of performance change for individuals. For the researcher, dips become the marker of exploration where performance suffers as new methods are invented and tested. Leaps mark the implementation of a successful new method and an incremental jump above the path plotted by smooth and steady log–log performance increments. The methods developed during these dips and leaps are the key to surpassing one's teachers and acquiring extreme expertise.  相似文献

The following study investigated the effect of poker competition on testosterone (T) responses. Thirty-two participants played one-on-one poker in a lab on campus. Saliva samples were obtained before and after the poker games. On average, participants produced a significant increase in T during the competition, with no difference between winners and losers. This study is the first of its kind to examine T responses in a gambling competition. Possible implications for destructive gambling behaviors are discussed.  相似文献

The current study builds on links between academic social identification and learning behaviours and extends these models by also considering the level of compatibility between the student identity and the pre‐existing self‐concept. This is a crucial extension, in the context of broadening access to higher education and fostering belonging and learning in nontraditional students. Further, where previous work focused on learning behaviours that enhance performance (often learning approaches), we also consider performance‐undermining behaviours (self‐handicapping and procrastination). These effects are explored in survey responses from an undergraduate student sample (N = 121) from UK and broader European samples. Participants were predominantly female (69%) and native English speakers (87%). Three models of the relationships between these variables were tested using Mplus. Results indicate that performance‐undermining behaviours are predicted by identity incompatibility, but not identification level; deep learning approaches are predicted by identification level, but not identity incompatibility. This provides first evidence that identity incompatibility is not just a moderator of the identification‐learning relationships but, in fact, a separate identity process for consideration. We also present initial evidence for a mediation model, where in the identity variables are related to procrastination and self‐handicapping via learning approaches.  相似文献
