While a variety of cognitive deficits and biases have been found to characterize aggressive and delinquent children and youth, very little attention has focused on determining whether aggressive youth also display deviant attributional beliefs in response to social failure. Research in the more impersonal cognitive domains such as achievement has shown attributions for failure to be potent determinants of both affective rections and subsequent responding. Thus, the present study was designed to investigate whether specific attributional patterns following social failure may also relate to aggressive behavior. The aim of this study was to determine the relation betweeen the level of self-reported physical aggression and specific atttributional patterns following hypothetical social failure in a sample of incarcerated delinquent males. While the general hypotheses were that increased aggressiveness would be related to a greater tendency to endorse attributions for social failure that are external, stable, and controllable, only the hypothesis with regard to controllability was supported. The findings are discussed in terms of the relation between cognition and aggression in delinquent youth.This research was supported in part by grant MH 44768-01 from the National Institute of Mental Health to the first author. The authors would like to thank the staff of the Illinois Youth Center-St. Charles for their cooperation. 相似文献

Examined a program designed to prevent adolescent pregnancy, school failure, and dropout using a process model of evaluation to assess with which groups of participants and under what conditions the program was most effective. Students in the Teen Outreach Program of the Association of Junior Leagues and matched comparison students in 35 schools nationwide participated. Sites that highly utilized a volunteer service component, and sites that primarily served older students reported lower levels of student problem behaviors at program exit, after controlling for problem behaviors at entry. These findings occurred only for program youths and not for comparison youths. The connection of volunteer service to reductions in adolescent problem behaviors is interpreted in terms of helper-therapy and empowerment theories. Limitations of the analytic strategy used in this study, as well as techniques for addressing the limitations, are also discussed. 相似文献

It is often assumed that the chief responsibility medical professionals bear is patient care and advocacy. The meeting of other duties, such as ensuring a more just distribution of medical resources and promoting the public good, is not considered a legitimate basis for curtailing or slackening beneficial patient services. It is argued that this assumption is often made without sufficient attention to foundational principles of professional ethics; that once core principles are laid bare this assumption is revealed as largely unwarranted; and, finally, that these observations at the level of moral theory should be reflected, in various ways, in medical practice. Specifically, this essay clarifies a tension that exists between different kinds of moral principles and explores the possibility of dissipating that tension by shoring up foundational principles. The paper begins by setting out three alternative models of how best to balance patient advocacy responsibilities with broader social responsibilities. It then turns to critically assess these models and argue that one has several advantages over the others. 相似文献

This field experiment explored the use of informational brochures to encourage home radon testing. Homeowners ( N = 271) received a radon brochure, a questionnaire, and a form for ordering a $20 radon test kit. The brochures differed in their presentations of the magnitude of the threat (varying risk likelihood and severity) and the difficulty of reducing radon levels. Some also included a detailed list of home radon risk factors. Combinations of these three variables yielded a 2 × 2 × 2 factorial design. Although 19.2% of the sample ordered tests, the percentage was constant across brochures. Data from the questionnaire showed that self-reported risk likelihood, risk seriousness, and concern were strongly correlated with intentions to test and with actual test orders. Calculations revealed that although the threat manipulation had a highly significant effect on these risk perceptions, the effect was too small to produce different rates of test orders. Confirming previous radon studies, perceived mitigation difficulty proved unrelated to interest in radon testing. 相似文献

This study investigated the relationship between stages of adult life development and causal attributions for attending college among a sample of nontraditional students. It was hypothesized that the meaning of attending school is reflected in the kinds of attributions that are given for attending school. It was also hypothesized that internal attributions are more common at later stages of adult life development. The findings confirmed the existence of internal and external (career and situational) cognitive attributional dimensions, with the internal dimension being the strongest. Coherent stages of adult life development were identified, which corresponded to a transitional stage, an early adult stage, and a mid-adult stage. Students in the transitional stage were less likely to give external situational attributions, and students in the mid-life stage were more likely to give external situational attributions. There was also a tendency for internal attributions to increase during the mid-life phase, although the relationship was not highly significant. The findings are discussed in the context of attribution theory and adult life development theory as well as in terms of implications for educational policy. 相似文献

We report the effects of using a visual and auditory stimulus signaling impending painful medical procedures versus “safe” periods on the affective behavior of a hospitalized infant. The results of a reversal design suggested that the signaling procedures increased positive behaviors and decreased negative behaviors during both noninvasive and invasive caregiver events. 相似文献

The present study investigated young adolescents' beliefs about the use and effectiveness of their strategies for coping with anger. Our goal was to examine how variations in the event provoking anger (being hit vs. having rumors told about oneself), the level of anger reported in response to the event, and the gender of the subject were related to choices and effectiveness ratings of three types of coping strategies: expressive (hitting, yelling, displacing), avoidant (getting away, doing something fun, doing work), and approach (talking to the offender, talking to someone else, thinking about the problem). Gender, the provoking situation, and the level of reported anger were all found to be related to ratings of both the use and effectiveness of these three types of strategies, and the relationships included interactions among these factors. In the rumor situation, girls endorsed approach strategies more often than boys and expressive strategies less often than boys. In contrast, in the hit situation girls rated the expressive strategies more highly than did boys. Adolescents in the hit situation with high ratings of anger were more likely to endorse expressive strategies than were those who reported minimal anger in this situation, the latter favoring avoidant and approach strategies. These anger level effects were not apparent in the rumor situation. Overall, adolescents reported using the strategies rated effective and not using those they saw as less useful. In addition, when given the option of multiple responses, adolescents favored a sequence in which expressive strategies were selected first, followed later by approach strategies. However, this sequence, like the overall ratings of strategy use and effectiveness, varied with gender, the provoking situation, and the level of reported anger. Our findings highlight the complex nature of anger and anger control in early adolescence and point to the importance of context, both individual and situational, in understanding coping responses. 相似文献

A series of five experiments was conducted to test the optimal speed for performing two- and three-dimensional imagery tasks. Subjects were required to keep track of the location of a pathway in an imagined matrix, as the directions of its successive movements were described verbally. Matrices varied in size and in number of spatial dimensions, with two-dimensional matrices drawn on cardboard and three-dimensional ones built from wooden blocks. When subjects were able to dictate the rate of presentation of the terms describing the pathway, they preferred slower rates for three-dimensional than for two-dimensional stimuli. In subsequent experiments, very fast presentation rates had a larger detrimental effect on performance with three-dimensional matrices than with two-dimensional matrices. A comparison of the patterns of performance for subjects who generally scored high with the patterns for those who scored low showed a stronger effect of dimensionality for poor performers, suggesting that individual differences mediate performance on the task. 相似文献
