We report investigations of change in, and cognitive representation of young people's stereotypes of the police, in response to a police-schools liaison programme. This programme provides a real-life application of the ‘conversion’ model of stereotype change (in which stereotypes change radically in response to salient instances of disconfirming information). Study 1 revealed that school police officers were rated significantly more positively than the police in general, but that this view did not generalize to perceptions of the police in general. Stereotypes of the police became less positive over one year, although females were more positive than males, and school police officers were not judged typical of the category. Study 2 revealed that subjects categorized their school police officer separately from the police in general, and perceived him to share features with ‘caring and welfare’ professions, rather than other police officers and authority figures. Both studies converge on the limitations of the conversion model and tend to support the subtyping model (in which extremely disconfirming individuals are isolated from other group members). 相似文献

A method and an apparatus are described for measuring the point at which subjects elect to stop smoking when cigarette smoke is delivered more rapidly than in typical smoking. The device allows either the subject or the experimenter to control the volume of smoke and the interval between puffs. The device delivers reliable quantities of particulate matter from cigarette smoke. Subjects retested a week apart exhibited consistent stopping points. 相似文献

In the Protagoras, Socrates argues that each of the virtue-terms refers to “one thing” (εν: 333b4). But in the Laches (190c8–d5, 199e6–7), Socrates claims that courage is a proper part of virtue as a whole, and at Euthyphro 11e7–12e2, Socrates says that piety is a proper part of justice. But A cannot be both identical to B and also a proper part of B – piety cannot be both identical to justice and also a proper part of justice. In this paper we argue that coherent sense can be made of Socrates' apparently conflicting claims. The key to understanding Socrates' position, we will argue, is the central role of wisdom among the virtues. It is through the relationship of each virtue to wisdom that each may be said to be the same as all of the others, on the one hand, and also that some virtues may be regarded as proper parts of some other virtues, or as proper parts of virtue in general, on the other. 相似文献

The relationship between contemporary household family structures at fourth-grade and sixth-grade parent- and teacher-rated aggression was examined in an epidemiologically defined population of urban school children. The relationship between family structure and aggression varied by child gender and by parent and teacher ratings in the home and school, respectively. After taking into account family income, urban area, and fourth-grade aggressive behavior, boys in both mother—father and mother—male partner families were significantly less likely than boys in mother-alone families to be rated as aggressive by teachers. No significant relations between family structure and teacher- or parent-rated aggression were found for girls.This work was supported by the following National Institute of Mental Health (NIMH) grants: Epidemiologic Prevention Center for Early Risk Behavior P50 MH38725; Periodic Outcome of Two Preventive Trials RO1 MH42968; and a Postdoctoral Training Program 2T32MH18834-06A1. The authors would like to thank the Baltimore Public City School System and the children and parents who participated. The views expressed here are those of the authors; no official endorsement by NIMH is intended or should be inferred.Address all correspondence and reprint requests to Dr. Ialongo, Department of Mental Hygiene, School of Hygiene and Public Health, Johns Hopkins University, 624 North Broadway, Baltimore, Maryland 21205. 相似文献

I show how scientism leads to deconstruction and both, in turn, lead to nihilism. Nihilism constitutes a denial both of the existence of fallacious moral reasoning and the existence of a moral dimension to fallacious reasoning. I argue against all of these positions by maintaining that (1) there is a pre-theoretical framework of norms within which technical thinking function, (2) the pre-theoretical framework cannot itself be technically conceptualized, and (3) the explication of this framework permits us to identify both fallacies of moral reasoning and the immorality of fallacious reasoning. 相似文献

During the 1980s, federal regulations transferred significant portions of the responsibility for monitoring the care and use of research animals from animal care programs to Institutional Animal Care and Use Committees (IACUCs). After a brief review of the history of the regulation of the use of animals in research preceding and during the 4 decades following World War II, this article raises 4 problems associated with the role IACUCs currently play in monitoring the use of animals in research: (a) lack of expertise, (b) diverted resources, (c) conflict of interest, and (d) restrictions of academic freedom. It is concluded that the care and treatment of animals used in research would be served better and organized more rationally if the day-to-day responsibilities for approving projects and caring for animals were separated more clearly from broader, oversight functions, with the former being assigned to animal care programs and the latter to IACUCs. 相似文献

A line of constant width viewed against an expanding or contracting grating appears to become narrower or wider, respectively. This effect was studied using a computer-controlled video system with a motorized zoom lens. The magnitude of the illusory size (width) change with a vertical line did not differ when viewed against a horizontal or an oblique background, and the size change was not due to static size contrast between the line and the background. The illusory narrowing observed with an expanding background was equivalent to the widening observed with a contracting background. The apparent change in the width of lines that actually expanded was consistently underestimated, either on a similarly changing background or when viewed against a gray field. Although the transformation of the background and line produced changes in their perceived distance, this did not occur for a constant line against a transforming background, even though this condition induced the perceived size change. 相似文献

Heart rate and motor responses were recorded in cats of different ages during classical conditioning. A deceleratory-acceleratory heart rate pattern observed during the CS-US interval in one and four-week-old kittens is an alpha conditioned response, a potentiated original response to the CS. At eight weeks of age two new distinct patterns of pure acceleration or pure deceleration are acquired during conditioning and in the absence of motor learning. At 12 weeks of age and in adult subjects, heart rate patterns during the CS-US interval become more complex and conditioned motor responses can be observed. A covariance of HR acceleration and motor responses during the CS-US interval is absent in eight-week-old subjects, but quite high in 12-week-old subjects and adult cats. The data are interpreted as suggesting separate elicitatory mechanisms of HR and motor responses which may show synchrony later in ontogeny. 相似文献

The author presents an interesting version of the Narcissus myth which she combines with the legend of Peter Pan for a better understanding of the narcissistic personality in group therapy. A lively case is presented of a young man named Jeffrey, whose narcissistic defenses were dismantled during a three-year group participation. A particular encounter between Jeffrey and another client and a powerful intervention by the therapist is described. The therapeutic importance of the group therapist as a firm but protective parent for these clients is emphasized. Definitions of narcissistic are given and some generalizations about these personalities in group therapy are explored.She has completed a book entitledChange in the Context of Group Therapy to be published by Brunner/Mazel in 1984. 相似文献
