This paper examines the culture, the dynamics and the financial underpinnings that determine how medical research is being conducted on children in the United States. Children have increasingly become the subject of experiments that offer them no potential direct benefit but expose them to risks of harm and pain. A wide range of such experiments will be examined, including a lethal heartburn drug test, the experimental insertion of a pacemaker, an invasive insulin infusion experiment, and a fenfluramine "violence prediction" experiment. Emphasis, however, is given to psychoactive drug tests because of the inherent ethical and diagnostic problems involved in the absence of any objective, verifiable diagnostic tool. Effort is made to provide readers comprehensive reference sources to evidence-based reports about the serious risks these drugs pose for adults and children so that the reader may judge whether the benefits (if any) outweigh the risks for children. 相似文献

The evaluation of everyday memory (EM) was reviewed and reconceptualized. EM has established new objectives of study and the development of new methods to reach these objectives . At the basic level, this approach has already produced important discoveries and the development of new principles about memory and functioning. At the clinical level, this new area of investigation has resulted in evaluating deficits of EM, which is defined as what daily life functions remain impaired after a deficit pathology has occurred. A type of evaluation has evolved that is oriented toward treatment and extremely useful in designing rehabilitation programs for individuals with alterations in memory. 相似文献

Previous studies have promoted the use of elaborative interrogation (a “why”-questioning strategy) for the acquisition of factual information. One assumption in these studies is that prior knowledge influences when students will be able to use the strategy, with greater prior knowledge leading to higher recall performance. In the studies reviewed here, the effect of prior knowledge on strategy effectiveness was investigated. Specifically, students' performances were compared for materials about which they possessed substantial prior knowledge, little prior knowledge, inconsistent prior knowledge, or shared prior knowledge. In general, the data support the use of elaborative interrogation when studying alone or in dyads especially when learners possess some relevant prior knowledge about the new information. 相似文献

People typically attribute lower health risks to themselves than to others, a phenomenon referred to as unrealistic optimism. The present study tested the person positivity bias as a previously unexamined explanation of the phenomenon and analyzed the relationship between unrealistic optimism and expectations of control. High-school students estimated their own and one of three other persons’(the average student's, a randomly chosen student's, or their best same-sex friend's) chances of getting health problems. They also filled out questionnaires measuring locus of control and health-protective behavior. In contrast with the person positivity explanation, unrealistic optimism was not restricted to the “average other” condition. However, unrealistic optimism was stronger in subjects with a more internal locus of control than in subjects with a rather external locus of control. An unpredicted effect of estimation order was observed: Unrealistic optimism was stronger in subjects who estimated the comparison person's risks first than in subjects who started with own risks. This effect can be understood in terms of Codol's observation that people perceive others as more similar to themselves than they themselves are to others. 相似文献

The subject of this research is the deprivation of freedom at two time points. A total of 490 convicts from open, semi‐open, and closed prisons participated in the research. Freedom deprivation intensity was determined by using the freedom deprivation scale (α = .93). The results of the research indicate that almost all the participants reported freedom deprivation. The prison type had an impact on freedom deprivation intensity, whereas an influence of the ward type on deprivation was not demonstrated. Freedom deprivation intensity was consistent from the turn of the century to the present day. 相似文献

We investigated whether category focus at encoding affects how people estimate category frequencies. Participants in three experiments viewed items of various categories. They estimated category frequencies after categorizing them into relevant versus irrelevant categories (Experiments 1-2) or after categorizing versus memorizing them (Experiment 3). Verbal protocols (Experiments 2A and 2B), response latencies (Experiments 2A and 2B), frequency estimate changes (Experiment 2B), and the relationships between objective and estimated category frequencies and instance recall (Experiments 1-3) showed that the participants mainly used availability to estimate category frequencies after memorizing instances (Experiment 3) or after categorizing them into irrelevant categories (Experiments 1-2). After categorizing items into relevant categories, the participants relied more often on stored category frequency information (Experiments 1-3). 相似文献

Conducted a qualitative investigation to identify the perceptions of risk factors for violence in a sample of inner-city African American youth. Using ethnographic analyses, themes emerging from these data included concerns about the reciprocity between drugs and violence, familial quality of life issues, gender differences in the experience of violence and risk for violence, community safety concerns, and fears about managing peer relationships specific to violence. These data are interpreted relative to the risk factors the violence prevention literature has identified among youth residing in urban environments. Findings are discussed in terms of their potential contribution to generating hypotheses for the development of theory and effective violence prevention practice. 相似文献
