We studied how evaluation of changes in low-probability risks are affected by reference points and framing effects. Subjects considered hypothetical situations with one or two low-probability risks. Different frames were used to describe changes in risk levels. In the first experiment, subjects chose between risk-reduction options that achieved the same overall risk reduction: large reduction of one risk vs. equal (smaller) reduction of two risks. When the risks were described as losses relative to the no-risk ideal, more subjects were indifferent between the options than when the same options were described as gains relative to the status quo. In the latter case subjects preferred equal reduction of both risks, unless one risk could be reduced to zero. In a related experiment, subjects were less willing to pay any price for a commodity that carried small increases in two risks than for a commodity carrying a comparable large increase in one risk. In other experiments, subjects evaluated single changes in risks rather than comparing or evaluating pairs of changes. Subjects again placed particularly high value on reducing any risks to zero, and they were even more inclined to do so when some other risk would also be reduced to zero. In a final experiment, elimination of risk was found to be less highly valued if its source was not fully eliminated, and a status-quo effect was found. The findings are interpreted in terms of reference theories of choice. 相似文献

This paper presents findings from a study of children lookedafter by 24 local authorities. It combines analysis of statisticaldata with analysis of qualitative and quantitative data froma questionnaire survey of a targeted sub-sample of childrenwho had been looked after for 4 years or more. The paper highlightsa complex picture of continuity and discontinuity in attemptsto achieve stability and permanence in a range of birth family,foster care, adoption, residential and leaving care placementsfor long-stay children. Some long-stay children are moving smoothlyand in a planned way towards a family for life, while some experiencelong periods in stable but temporary placements or have a numberof moves prior to finding stability and a sense of belonging.A further group of children experience stability or moves whilelooked after, without having a family to belong to when theymove into adult life. The paper discusses the difficulty withthe Governments current long-stay performance measurein capturing the difference between stability in placement andplanned permanence for children and families. 相似文献

Previous research has documented an association between adolescent community violence exposure (CVE) and poor psychological functioning. The purpose of this study is to delineate the relations of CVE, parental mental health, and adolescent PTSD and depression. Participants consisted of 121 pairs of junior high and high school students and their parents. Adolescents completed measures to assess their history of violence exposure and current psychological functioning. Parents completed a demographic questionnaire and measures assessing their psychological functioning. Hierarchical regression analyses were conducted, and results indicated that, after controlling for demographic variables and family violence exposure, parental mental health emerged as a moderating variable in the relation between CVE and adolescent-rated PTSD, but not in the association between adolescent CVE and depression. Clinical implications of this study and directions for future research are discussed. 相似文献

The paper presents some key findings of qualitative research with older primary school children in Wales on their attachments to places and cultures. There is discussion of children's perspectives on the global, national and local arenas. We argue both that there are continuities with adult perspectives and that the children's views on place and identity need to be understood in the context of the social location of middle childhood. The study shows children making relatively little use of culturally-filled categories of local, national and global place-identifications. The differences they articulate are largely framed in terms of divisions between groups of people rather than in the characteristics of place, and generally related back to the self. 相似文献

People's perceptions of benefits and risks play a key role in their acceptance or rejection of medical interventions, yet these perceptions may be poorly calibrated. This online study with N = 373 adults aged 19–76 years focused on unrealistic optimism in the health domain. Participants indicated how likely they were to experience benefits and risks associated with medical conditions and completed objective and subjective numeracy scales. Participants exhibited optimistic views about the likelihood of experiencing the benefits and the side effects of treatment options described in the scenarios. Objective and subjective numeracy were not associated with more accurate ratings. Moreover, participants’ underestimation of the risks was significantly greater than their overestimation of the benefits. From an applied perspective, these results suggest that clinicians may need to ensure that patients do not underestimate risks of medical interventions, and that they convey realistic expectations about the benefits that can be obtained with certain procedures. 相似文献
