The individual deciding on a nuclear weapons production policy is faced with a dilemma in which a choice must be made to support one of several conflicting defense policies. In order to investigate the social-psychological variables that are related to armament policy decision making, a telephone survey was conducted in the City of St. Louis, Missouri. Adult subjects (N= 110) responded to questions concerned with cognitive, attitudinal, and emotional responses to nuclear arms. Participants were also asked to choose a weapons production policy for the United States under conditions of continued and decreased Soviet nuclear arms production. Results indicated that respondents decisions about nuclear weapons production were related to their support for deterrence, the availability of their nuclear-related images, their emotional response to nuclear war, their attributions of responsibility for the prevention of nuclear war, and their political party affiliation. Distinctions between antinuclear decision-makers and pronuclear decision-makers are discussed.  相似文献

Evidence increasingly links a high-fat, low-fiber diet to coronary heart disease and certain site cancers, indicating a need for large-scale dietary change. Studies showing the effectiveness of particular procedures in specific settings are important at this point. The present study, using an A-B-A-B design and sales data from computerized cash registers, replicated and extended previous work by showing that inexpensive prompts (i.e., signs and fliers) in a national fast-food restaurant could increase the sales of salads, a low-fat, high-fiber menu selection. Suggestions also are made pertinent to more widespread use of the procedures.  相似文献

Gender differences in friendship patterns   总被引:1,自引:0,他引:1  
The same-sex and opposite-sex friendship patterns of men and women students from two first-year psychology classes at the University of Waikato in New Zealand were examined. A friendship questionnaire previously used in the United States of America was administered to compare results of the two cultures. Findings from this study support American research suggesting that women are more intimate and emotional in their same-sex friendships than men, and tend to place a higher value on these friendships than men do. In accordance with findings of the American sample, New Zealand women emphasized talking, emotional sharing, and discussing personal problems with their same-sex friends, and men showed an emphasis on sharing activities and doing things with their men friends. Differences between the American and New Zealand samples were shown for men in the number of friends and the intimacy levels of these friendships. New Zealand men preferred numerous but less intimate same-sex friends, while women (as in the United States) showed a preference for a few, close, intimate same-sex friends. Men, in contrast to women, derived emotional support and therapeutic value more from their opposite-sex relationships than their same-sex friendships. Finally, more men than women stated they would not cancel an engagement with an opposite-sex friend in order to go out with a same-sex friend. Results are interpreted as suggesting a need for changes in the current socialization process of males who are taught to repress their emotions and form rather less intimate and possibly less beneficial same-sex friendships than women.  相似文献

This paper reports on an unusual study of survivors of rape and the effects on the victim, her significant male other person, and her parents. All survivors were victims of the same rapist and were interviewed from 21 months to ten years after the event. The study indicates that the long-term effects of rape may be more significant than previous researchers and practitioners thought was the case. Recommendations are given for more effective help for survivors and those close to them.This study was funded by the Ohio Department of Mental Health, Office of Program Evaluation and Research, Columbus, Ohio, 1985.  相似文献

This study assessed how confidence in judgments is affected by the need to make inferences about missing information. Subjects indicated their likelihood of taking each of a series of gambles based on both probability and payoff information or only one of these sources of information. They also rated their confidence in each likelihood judgment. Subjects in the Explicit Inference condition were asked to explicitly estimate the values of missing information before making their responses while subjects in the Implicit Inference condition were not. The manner in which probability information was framed was also manipulated. Experiment 1 employed hypothetical gambles and Experiment 2 employed gambles with real money. Expressed likelihood of taking gambles was higher when probability was phrased in terms of '% chance of winning' rather than '% chance of losing', but this difference was somewhat less with real gambles than with hypothetical gambles. Confidence ratings in each experiment were actually higher on incomplete information trials than on complete information trials in the Explicit Inference condition. Results were related to the general issue of confidence in judgments.  相似文献
