Until now, no general scales have been available for measuring victim or society blaming. This constraint has been an impediment to policymaking with regard to those who are affected by social problems. Four scales were constructed: stable victim-blaming scale, unstable victim-blaming scale, stable society-blaming scale, and unstable society-blaming scale. Based on the results of the preliminary exploratory factor analysis and the reliability coefficients, the unstable society-blaming scale was deleted from further analysis. Then, a confirmatory factor analysis using the LISREL 7 program was conducted to evaluate the parameter estimates of the scale items and examine the construct validity of the 3 scales. The scales were judged to have construct validity with satisfactory reliability. 相似文献

The efficacy of three different schedules of reinforcement for promoting and sustaining drug abstinence was compared in this study. Cigarette smoking was studied as an exemplar of stimulant drug self-administration. Sixty cigarette smokers were assigned to one of three groups (progressive rate of reinforcement, fixed rate of reinforcement, and yoked control). Participants in all three groups were asked to refrain from smoking for 1 week. Participants in the progressive and fixed groups achieved greater mean levels of abstinence than those in the control group. Participants in the progressive group were significantly less likely to resume smoking when they became abstinent than participants in the other groups. 相似文献

This study builds on previous theory of planned behavior (TPB) studies in which we identified the beliefs and values which predict intention to commit driving violations. Four short experimental videos were developed in order to assess the effectiveness of an intervention grounded in the TPB. Three of the videos featured the major constructs of the TPB model. The fourth video featured anticipated regret, an addition to the TPB model which had previously been shown to add significantly to its predictive performance (Parker, Manstead, & Stradling, 1995). Results indicated that two of the videos brought about statistically significant belief changes with respect to scores on TPB items, and significant changes in general attitudes toward speeding. Discussion centers on the problems encountered in operationalizing the TPB constructs and on the potential of theory-based interventions to induce attitude change. 相似文献

Tasks and timing in the perception of linguistic anomaly 总被引:3,自引:0,他引:3

Three experiments were conducted to investigate the relative timing of syntactic and pragmatic anomaly detection during sentence processing. Experiment 1 was an eye movement study. Experiment 2 employed a dual-task paradigm with compressed speech input, to put the processing routines under time pressure. Experiment 3 used compressed speech input in an anomaly monitoring task. The outcomes of these experiments suggest that there is little or no delay in pragmatic processing relative to syntactic processing in the comprehension of unambiguous sentences. This narrows the possible explanations for any delays that are observed in the use of pragmatic information for ambiguity resolution.The research reported in this paper was supported by Program Project Grant HD-01994 to Haskins Laboratories from the National Institutes of Child and Human Development, and in part by a grant to Stephen Crain and Donald Shankweiler from the University of Connecticut Research Foundation. We thank Jacques Mehler and Gerry Altmann for helpful information about speech compression algorithms. We are especially grateful to Ignatius Mattingly for his generous expert advice on speech compression and design of the experimental materials, and also for recording all the speech stimuli. Julie Boland, Brian McElree, Janet Nicol, and Martin Pickering provided very helpful advice on an earlier draft. 相似文献

The health belief model was evaluated for its ability to predict perceived and actual dietary quality. The assessment relied upon data collected from 1,502 respondents by the US. Department of Agriculture in its 1991 Continuing Survey of Food Intakes by Individuals and the Diet and Health Knowledge Survey. The health belief model provided good prediction of perceived dietary quality, but provided moderate to weak prediction of 7 measures of actual dietary quality that were calculated from food intake records. Implications are suggested for using the health belief model to understand the determinants of dietary quality. 相似文献

The purpose of this study was to determine the extent of agreement among a panel of rational-emotive therapy (RET) experts about the essence of RET. The panel of experts consisted of the 9 members of The International Training Standards and Review Committee of the Institute for Rational-Emotive Therapy in New York. The question that the experts were asked was an adaptation of a Talmudic story known in Jewish lore as “While Standing on One Foot.” Responses were assigned to either of 2 categories: general cognitive behavior therapy (CBT) or RET-specific. There seems to be a range of responses that capture the essence of RET. A strong case can be made for subsuming many aspects of CBT under RET because much of what is associated with CBT has its origins in RET. The confusion about where RET ends and general CBT begins goes to the very heart of RET's status today. 相似文献

In this article we explore ethical issues arising in a study of home Internet use by low-income families. We consider questions of our responsibility as educational researchers and discuss the ethical implications of some unanticipated consequences of our study. We illustrate ways in which the principles of research ethics for use of human subjects can be ambiguous and possibly inadequate for anticipating potential harm in educational research. In this exploratory research of personal communication technologies, participants experienced changes that were personal and relational. These unanticipated changes in their way of being complicated our research relationships, testing the boundaries of our committment to the principle of trustworthiness and forcing us to reevaluate our responsibilities. 相似文献

This paper develops a model wherein STM primacy as well as recency effects can occur. The STM primacy effects can be used to generate correct immediate recall of short lists that have not been coded in LTM. The properties of the model are interpreted in terms of explicit neural mechanisms. The STM primacy effect is a behavioral contrast effect that is analogous to the behavioral contrast that can occur during discrimination learning. The adaptational mechanism that accounts for these effects is also implicated in data on reaction time, retinal adaptation, ratio scales in choice behavior, and von Restorff-type effects. Its ubiquitous appearance is due to the fact that it solves a universal problem concerning the parallel processing of patterned data by noisy cells with finitely many excitable sites. It is argued that the STM primacy effect is not measured in interference experiments because it is masked by competitive STM interactions. These competitive interactions do not prevent the LTM primacy effect from influencing performance. The paper criticizes recent models of STM that use computer analogies to justify binary codes, serial STM buffers, and serial scanning procedures. Several deficiencies of serial models in dealing with psychological and neural processing are overcome by a model in which continuous STM activities and parallel real-time operations play an important role. 相似文献
