Changes in the wording of core measures of political attitudes in the American National Election Studies have generated a good deal of controversy about artifactual sources of change in the U.S. electorate. This research, based on several field experiments and replications, investigates the effects of using or not using various types of opinion filter questions that have appeared in the SRC/CPS series over the years. The analysis shows that the use of a filter interacts significantly with a respondent's level of education and interest in politics, particularly the latter, in determining whether a respondent will offer an opinion on a given public policy issue. But the study also demonstrates that such an interaction occurs primarily when the question about interest in politics is askedafter, rather thanbefore, a set of political issue items. In interpreting these order-and-context effects the authors develop a self-perception model of how respondents infer their interest in politics from information that isavailable in memory about their own behavior in the survey interview. 相似文献
A basic tenet of the new conservatism in political economy is that government policies frequently lead to unintended consequences which may offset the benefits of the policy. Auto safety legislation may be a case in point. As the first country to make the wearing of seat belts compulsory, Australia is highly suitable as a case study. Traffic accident casualties were regressed on six independent variables for the pre-seat belt period 1949–71. The equations were then used to predict casualties for the period 1972–77, using the actual values of the independent variables. In the aggregate, predicted occupant casualties were higher than the actual rates, whereas non-occupant casualties were underpredicted by the equations. An additional test, using a dummy variable to predict the effect of seat belts, supported these conclusions. The results are consistent with the hypothesis that drivers respond to a reduction in risk by increasing driving intensity, shifting some of the welfare cost of auto safety legislation on to non-occupants, whose casualty rates are higher than they would have been in the absence of seat belt legislation.I am grateful to Chris Adam and to an anonymous reviewer for helpful comments and suggestions. 相似文献

The Computer-Aided Design Centre has developed a new face recall system which enables a witness to construct the image of a suspect on a television screen. The system currently uses the Photofit library and method of construction. Likenesses of target faces produced by subjects (n=36) using the new system were compared to conventional Photofits produced by a second group of subjects (n=36) of the same targets. There was no difference on any of the three measures employed in the assessed quality of the likenesses produced by Photofit and the CADC System. Both systems tended to produce more recognizable composites when construction was carried out in the presence of the target compared to its absence. Composites made from memory on the initial trial were marginally better with the CADC System than with Photofit. While both systems showed low absolute accuracy, they enjoyed a measure of success in transmitting a likeness of a facial type. It is concluded that while the CADC system shows promise, psychological constraints upon witnesses' powers of recall may place limits on the absolute accuracy achievable with any system of face reconstruction.These experiments were financed by grant No. POL/73 1675/24/3 from the Police Scientific Development Branch of the U.K. Home Office. Points of view expressed in this article are solely those of the authors and do not necessarily reflect the opinions or positions of the funding body. Our gratitude and thanks are due to Tony Kitson and Clive Holloway for their many hours spent developing and operating the CADC system; Jean Shepherd for her skills as a Photofit operator; the Computer-Aided Design Centre; and the MRC Applied Psychology Unit, Cambridge for facilities and subjects. 相似文献
A number of social and psychological factors present in most adolescent parents place them at high risk for abusive behavior toward their children. However, current child abuse potential measures do not include adolescent samples as part of the psychometric data base. Consequently, the purpose of this study was twofold: (1) to investigate whether a Black adolescent sample would perform differently than an adult nonabusing sample on the Child Abuse Potential Inventory (CAP), and (2) to examine the relationship between history of abuse or witnessing violence to scores on the CAP. Results revealed that Black adolescents scored significantly higher than the adult normative sample on the CAP; consequently, cutoff scores need to be empirically established for adolescents. Additional analyses indicated that a history of abuse, as well as a history of witnessing violence, are associated with a high potential for abuse. 相似文献
