This research examined the relationship between White racial consciousness development and perceived comfort with Black individuals. Participants were 339 White undergraduate students from a large southeastern state university who were asked to complete a two-part inventory: part one measuring White racial consciousness development (a five-stage scale) and part two measuring perceived comfort in situations involving Black individuals. An eta coefficient was calculated, providing evidence for the existence of a strong curvilinear relationship between White racial consciousness and perceived comfort with Black individuals η =.23 at p<.0001. These findings suggest that Whites who are completely foreclosed (stage one) or who are well acquainted with Blacks (stage five) are more comfortable in situations with Blacks than Whites who had a moderate amount of contact with them (stages two, three, and four).  相似文献

The increasing incidence of AIDS has created a societal fear of AIDS that, in turn, has raised the level of fear and anxiety in individuals prone to fear responses. Fears accentuated by AIDS are discussed and guidelines for counseling offered.  相似文献

The Sentencing Reform Act of 1984, which created the U.S. Sentencing Commission, required that the commisson consider prison capacity in drafting sentencing guidelines. As part of the commission's efforts to meet this requirement, we developed a computer simulation capable of projecting the impact of the commission's guidelines on future sentences and prison populations. According to our projections, “straight” probation sentences will be reduced significantly under the guidelines. However, reducing the use of probation will generate only modest demands on the prisons, and then mostly for community corrections phased in over the course of 5 years. We also project that, while average time served for violent offenses will increase substantially, average time served for most property crimes will remain largely the same. Finally, while we forecast that federal prison populations will grow markedly by the end of this century, this is more a result of the Anti-Drug Abuse Act of 1986 and the career offender provision of the Comprehensive Crime Control Act of 1984 than a result of the guidelines.  相似文献

This article reviews the history of and basis for mental health testimony. It surveys the roles of such experts in the legal system and the concomitant problems with current approaches. Finally, it suggests specific reforms that may improve the use of mental health experts in legal proceedings.  相似文献

This article provides a critical review of two major types of expert evidence: (a) clinical assessments, and (b) generalizations drawn from psychological research. Strong arguments both for and against both types of testimony have been offered by legal experts and psychologists. These arguments are evaluated and the conclusion is drawn that there are two fundamental problems for psychologists in the role of expert. First, the types of assessments clinicians are asked to make (e.g., concerning the accused's mental state at the time of committing the offense) may exceed the capacity of the discipline; such assessments are problematic. Second, the research foundation that psychologists employ in court does not always apply to the court situation in the way experts imply; the application of laboratory research findings to real world contexts is sometimes premature. The article concludes with an admonition that psychologists should adopt a more conservative response to requests to provide expert evidence.  相似文献

Available data indicates that the incidence of malpractice in military psychiatry, involving both civilian and active duty beneficiaries, is the lowest of all specialties and may be lower than in the civilian sector. Recovery for malpractice damages by means of claim versus suit is restricted to civilian patients; active duty service members recover through a special disability system. The federal government provides military psychiatrists with considerable protection from personal financial loss when involved in malpractice, but there may be limits to that protection. There have been recent efforts to criminally prosecute military physicians in some instances. A registry review of military psychiatry malpractice cases from 1978 to 1987provides a profile of the malpractice situation and suggests areas of practice that need vigilance. The Department of Defense has established a broad-based, comprehensive program of quality assurance and risk management in the interest of maximizing the benefit of medical care and minimizing substandard practice.  相似文献

Principles in the judgment/decision making literature relevant to the legal community are reviewed. These principles are divided into four areas: the decision process itself, communicating a judgment to others, evaluating a decision, and possible ways of “debiasing.” Several influences on the decision process are enumerated, among them being insufficient consideration of base rates, selective memory for relevant material, the framing of the decision in either the domain of losses or the domain of gains, and consideration of the “cues to causation.” Particular attention is paid to suboptimal consideration of covariation information. In communicating the decision to others the two most prominent findings are overconfidence in expressing one's decision and the inability to describe accurately the bases of one's decision. Evaluating a decision is plagued by two biases. The first is the hindsight bias. After an event has occurred we tend to exaggerate how easily we could have predicted the event beforehand. The second is the outcome bias. We tend to base our evaluation of the decision upon the evaluation of the outcome. Among the debiasing techniques mentioned are the admonition to “consider the opposite” of the preferred option, the reduction of reliance on memory, and the use of decision aids.  相似文献

This article examines the hindsight bias in the context of mental health malpractice litigation, analyzes various legal mechanisms for dealing with the bias, and discusses whether the law should strive for debiasing in all mental health malpractice cases.  相似文献
