Framing uncertain scenarios to emphasize potential positive or negative elements influences decision making and behavior. The current experiment investigated sex differences in framing effects on risk-taking propensity in a modified version of the Balloon Analogue Risk Task (BART). Male and female undergraduates completed questionnaires on sensation seeking, impulsiveness, and risk and benefit perception prior to viewing one of three framing conditions for the BART: (1) positively-framed instructions emphasizing the ability to earn money if balloons were inflated to large size; (2) negatively framed instructions emphasizing the possibility that money could be lost if balloons were inflated to bursting; and (3) completely framed instructions noting both possible outcomes. Results revealed correlations between BART performance and impulsiveness for both sexes. Compared to positive and complete framing, negatively framed instructions decreased balloon inflation time in women but not men, indicating sex differences in response to treatments designed to alter risk-taking behavior.  相似文献

Kipnis K  Williamson GM 《Ethics》1984,95(1):90-111
The authors draw on Kipnis' experiences in the clinical presentation of ethical problems arising in a newborn intensive care unit to analyze substantive criteria for decisions to stop life prolonging treatment and to determine the limits of parental authority to decide for nontreatment. They identify three decisions--treatment obligatory, treatment discretionary, and nontreatment obligatory--and apply the criteria of patient burdens and capability for a subjectively valuable life to each. Kipnis and Williamson consider parental authority to be a custodial role which should be assumed by others if the parents are unable or unwilling to secure for the child a subjectively valuable life.  相似文献

Observed in 2 initial studies was converging evidence that helping improves the helpers' moods and self-evaluations. In these studies Ss induced to help showed improved moods and self-evaluations relative to Ss not given an opportunity to help. A 3rd study examined the moderating effects of desired relationship type on reactions to having helped. In this study Ss were led to desire either a communal or an exchange relationship with another. They then helped the other or were not allowed to help. Among Ss led to desire a communal relationship, but not among those led to desire an exchange relationship, helping was associated with greater improvements in moods than not helping. Helping tended to improve self-evaluations regardless of desired relationship type. However, this effect reached statistical significance only among subjects led to desire a communal relationship.  相似文献

Body-image disturbances in bulimia nervosa: influences of actual body size   总被引:2,自引:0,他引:2  
This study evaluated body-image distortion and ideal body-size preferences in 423 nonbulimic women and 108 bulimics. Analyses of covariance were utilized to compare the bulimic and nonbulimic groups on measures of current and ideal body size. Weight was used as a covariate to evaluate the influence of actual body size on perception of current body size and selection of ideal body size. Bulimics chose current body sizes that were significantly larger than those picked by nonbulimics regardless of actual body size. Bulimics also chose thinner ideal body sizes than did nonbulimics, regardless of actual body size. These results suggest that body-image distortion and extreme preference for thinness are a fundamental characteristic of bulimia nervosa. These results were discussed in terms of how perception of a large body size and preference for a very thin body size might interact to produce a high degree of dissatisfaction and overconcern with body size in bulimia nervosa.  相似文献
