Joint attention, the tendency to spontaneously direct attention to where someone else is looking, has been thought to occur because eye direction provides a reliable cue to the presence of important events in the environment. We have discovered, however, that adults will shift their attention to where a schematic face is looking—even when gaze direction does not predict any events in the environment. Research with 2 split-brain patients revealed that this reflexive joint attention is lateralized to a single hemisphere. Moreover, although this phenomenon could be inhibited by inversion of a face, eyes alone produced reflexive shifts of attention. Consistent with recent functional neuroimaging studies, these results suggest that lateralized cortical connections between (a) temporal lobe subsystems specialized for processing upright faces and gaze and (b) the parietal area specialized for orienting spatial attention underlie human reflexive shifts of attention in response to gaze direction. 相似文献

In April 2002, the President's New Freedom Commission on Mental Health was created by executive order to study the mental health care delivery system in our nation and to make recommendations for improvements so that individuals with serious mental disorders can live, work, learn, and fully participate in their homes and communities. In its report, "Achieving the Promise: Transforming Mental Health Care in America," the commission provided strategies to address critical infrastructure, practice, and research issues. This article focuses on the work of the commission's Subcommittee on Children and Families, describing its vision for mental health service delivery for children and providing suggestions for strengthening community-based care for youths with or at risk of behavioral health disorders. Training, research, practice, and policy implications for psychologists are discussed. 相似文献

Handwritten autobiographies from 180 Catholic nuns, composed when participants were a mean age of 22 years, were scored for emotional content and related to survival during ages 75 to 95. A strong inverse association was found between positive emotional content in these writings and risk of mortality in late life (p < .001). As the quartile ranking of positive emotion in early life increased, there was a stepwise decrease in risk of mortality resulting in a 2.5-fold difference between the lowest and highest quartiles. Positive emotional content in early-life autobiographies was strongly associated with longevity 6 decades later. Underlying mechanisms of balanced emotional states are discussed. 相似文献

This study investigates the role that youth-level factors play in predicting help-seeking intentions in a nationally representative sample. Eleven help-seeking intentions were examined separately by target conditions (ADHD and depression), gender, race/ethnicity, and self-reported diagnosed/non-diagnosed in respect to the target conditions, and interaction effects were tested. Using factor analysis, a traditional help-seeking scale was created, which captured four help-seeking items, and predictive power of youth-level factors in accounting for traditional help-seeking was tested. Study findings provide practitioners and researchers with fresh evidence on what youth-level factors are associated with which help-seeking intentions, and illustrate the challenges involved in better understanding the complexity of the help-seeking process among youth in the context of ADHD/Depression. With increased understanding of youth’s perceptions and the complexity of their help-seeking behavior, community-based efforts to develop effective strategies that support active help-seeking behavior and eliminate barriers to appropriate care can have a greater likelihood of success. 相似文献

Assessment of risk is one of the key issues in the field of responsible conduct of research which covers discourses of research ethics and research integrity. The principle of minimizing risks and balancing of risks and benefits is one of the main requirements of research ethics. In addition, the content of informed consent that is another fundamental principle of research ethics derives from the assessment of risks and benefits related to a particular research project. Risk assessment also plays a crucial role in methodological design of the research project. This is an important point where research ethics and research integrity discourses overlap. Firstly, because the choice of a control group (e.g., placebo control) is a key ethical issue related to the protection of the research subjects' interests. Secondly, because the quality of the research data, that is one of the key elements of research integrity, is closely connected to the choice of research methodology as well. The problem of biased interpretation or manipulation of risk related features of biomedical research should also be taken into account. Despite the importance of the concept of risk to the field of biomedical research, its relevance has not yet attracted a sufficient attention in the responsible conduct of research debate. 相似文献

The Helsinki Declaration is a very important document regarding the protection of patients’ rights in clinical trials and
one of the fundamental sources of operational principles for every ethics committee. Although they have been updated, the
international guidelines for ethics committees continually fail to address certain issues pertaining to the protection of
patients’ rights in clinical trials. These issues include, most significantly, the method of electing ethics committees (a
free, secret ballot should be preferred to direct appointment), the avoidance of conflict of interest during the election
of ethics committee members, and the necessary insurance coverage for the participants of clinical trials. Polish law should,
on the other hand, be developed in such way as to not limit the effectiveness of ethics committees in protecting patients’
rights in clinical trials. The ideal solution would be to draft a uniform law concerning not only clinical trials, but all
medical experiments. The opinions of experts who have been reviewing medical research projects for several years may prove
to be especially valuable in this setting.
This paper was presented at the 6th International Bioethics Conference on the subject of ‘The Responsible Conduct of Basic
and Clinical Research’, held in Warsaw, Poland, 3–4 June 2005.
