Complex scientific testimony: How do jurors make decisions? 总被引:2,自引:0,他引:2
Critics of the civil jury system question whether jurors can adequately evaluate complex expert testimony. Based on current models of research in persuasion, we hypothesized that when expert testimony is complex, factors other than content will influence persuasion. Participants, serving as mock jurors, watched a videotaped trial in which two scientists provided evidence on whether PCBs could have caused a plaintiff's illness. The complexity of the expert's testimony and the strength of the expert's credentials were varied in a 2×2 factorial design. After watching the videotape, mock jurors rendered a verdict and completed a number of attitude measures related to the trial. Overall, consistent with our prediction, we found that jurors were more persuaded by a highly expert witness than by a less expert witness, but only when the testimony was highly complex. When the testimony was less complex, jurors relied primarily on the content of that testimony, and witness credentials had little impact on the persuasiveness of the message. 相似文献

Community-based policing requires a radically different philosophical and organizational approach from the more traditional approach to policing. Stress may be experienced during organizational change as areas of responsibility and roles are altered. This study had three primary objectives: to identify (1) the areas officers and their immediate supervisors actually consider stressful, (2) the officers' and supervisors' responses to stress, and (3) the influence of their social support systems on these responses. Data were collected from community coordinators, radio response officers, and sergeants of the Charlotte-Mecklenburg Police Department in North Carolina. The officers and sergeants report specific physiological responses, lack of job involvement, and propensity to leave law enforcement; all responses that are considered by the literature to be related to stress. Stressors that are both common in law enforcement in general and stressors unique to a department implementing community policing are found to be significant. Work social support does appear to affect the level of job involvement of the officers. The finding that sergeants do not appear to feel that they have work social support may be working to the detriment of their ability to cope with stress and their willingness to be involved with their job. 相似文献

Brief case histories involving incest were presented to police officers, child welfare workers, and community mental health practitioners in a rural area in Canada. Intervention priorities involving “treatment versus punishment” were assessed across the three professional groups for each specific case vignette. Attitudes were assessed on three factors: perpetrator mentally ill rather than criminal, view regarding treatment of victims and mothers, and support for court mandated treatment. Police and community mental health practitioners had significantly different attitudes as to whether perpetrators of child sexual abuse should be viewed more as criminals or as mentally disturbed. Both mental health and child welfare staff differed significantly from police with a less punitive view towards victims and their mothers. All three profressional groups showed no difference in their modest endorsement of the use of mandated treatment by the courts. Gender was not found to influence response to case vignettes. 相似文献
