This article discusses the phenomenon of "context effects" by reviewing the findings and practices of a range of scientific fields, including astronomy, physics, biology, medicine, and especially the relevant research and theory from psychology. Context information, such as expectations about what one is supposed to see or conclude, has been found to have a small but relentless impact on human perception, judgment, and decision-making. The article then considers the vulnerability of forensic science practice to context effects, and concludes by suggesting that forensic science adopt practices familiar in other fields of scientific work, in particular blind or double-blind testing and also the use of evidence line-ups.  相似文献

This study examined the psychological impact of stalking upon female undergraduates, a population previously determined to experience a surprising stalking prevalence rate. Despite common understanding that stalking has deleterious effects, there have been no previous efforts to systematically assess them with standardized measures. Thirty-six female stalking victims were compared with 43 females who had been harassed and 48 controls. Psychological impact was assessed with the Posttraumatic Stress Disorder Scale, the Symptom Checklist-90-R, and the Self-Report Interpersonal Trust Scale. Stalked subjects endorsed significantly more PTSD symptoms and with greater severity than the harassed or control subjects. Stalked subjects also had significantly higher scores on several subscales of the SCL-90, and had significantly higher positive symptom totals and distress indices.  相似文献

The conclusion of the Clinton Administration presents an opportune time to investigate the outcomes of the National Performance Review (NPR). Any such evaluation, however, is complicated by the nature of the objectives sought, many of which relate to subtle and elusive elements of organizational life: empowering employees, inducing a less risk-adverse culture, and enhancing the quality of service delivery. The strategy employed here as a means of gaining insight into such phenomena was to couple a broad review of government-wide survey results with an in-depth investigation into the impact of NPR on a single agency, the Social Security Administration. A conclusion is that many of the NPR's "higher-order" objectives have not been met on a systemic basis. While a variety of proximate explanations for this finding can be identified, a more fundamental explanation relates to a failure by the sponsors to adjust their strategy to account for basic differences between NPR and past reforms.  相似文献

Eleven incidents of carbon monoxide (CO) intoxication resulting in sixteen fatalities are reported. All of the cases involved heating systems as either the source or the means of distributing the CO. Blood samples were analyzed for ethanol and CO. Elevated blood CO saturations were found in 14 of the 16 victims while none of the victims had a blood ethanol concentration greater than 0.10% (w/v).  相似文献
