The application of neuroimaging technology to the study of the injured brain has transformed how neuroscientists understand disorders of consciousness, such as the vegetative and minimally conscious states, and deepened our understanding of mechanisms of recovery. This scientific progress, and its potential clinical translation, provides an opportunity for ethical reflection. It was against this scientific backdrop that we convened a conference of leading investigators in neuroimaging, disorders of consciousness and neuroethics. Our goal was to develop an ethical frame to move these investigative techniques into mature clinical tools. This paper presents the recommendations and analysis of a Working Meeting on Ethics, Neuroimaging and Limited States of Consciousness held at Stanford University during June 2007. It represents an interdisciplinary approach to the challenges posed by the emerging use of neuroimaging technologies to describe and characterize disorders of consciousness. 相似文献

Does unconscious perception at the objective detection threshold (ODT) exist? In this reply, formal meta-analyses of previously narratively reviewed evidence (Snodgrass, Bernat, & Shevrin, 2004) provide strong evidence for large, reliable unconscious perceptual effects, and further strengthen previous conclusions for their ODT status. These meta-analyses dispel general concerns that ODT effects are small, unreliable, or susceptible to file drawer concerns (cf. Reingold, 2004). Furthermore, the specific objections (Holender & Duscherer, 2004) to individual ODT effects are refuted, and objections to our proposed solutions to the exhaustiveness, exclusiveness, and null sensitivity problems (Haase & Fisk, 2004; Reingold, 2004) are shown to be inapplicable, contradicted by the available evidence, or both. Accordingly, the strong evidence for ODT effects, taken together with the nonmonotonic relationship, contradicts the single-process conscious perception model (e.g., Holender & Duscherer, 2004) and provides stronger evidence for unconscious perception than hitherto available. 相似文献

Correlates of concern about weight gain following smoking cessation and self-efficacy about controlling weight gain were examined in 940 men and 1,166 women who were surveyed on 2 occasions as part of a randomized trial of work-site interventions for smoking cessation. Weight concerns were positively associated with female sex, body weight, dieting for weight control, nicotine addiction, and social encouragement to quit. Bivariate analyses replicated prior findings that elevated weight concerns are associated with a reduced likelihood of quitting smoking, at least in women. Analyses controlling for demographics, nicotine dependence, and social factors replicated prior findings that weight concerns are not negatively related to smoking cessation and that some measures of concern are positively related to cessation. These analyses suggest that conflicting findings found in this literature are due primarily to how weight concerns are defined and whether covariates like nicotine addiction are used in data analyses. 相似文献

This study's purpose was to extend the distantresearch on gender roles. The specific objective was tobetter understand the gender role of male psychologists.It was hypothesized that male psychologists would exhibit an androgynous gender role.Gender role styles in professional work and in thepersonal realm were assessed. Questionnaire packets weremailed to 300 male clinical psychologists affiliated with the American Psychological Associationacross six regions within the United States. Sixty ofthe 61 participants reported being Caucasian and 1reported being Native American. Being that the sample was that of practicing psychologists, all withdoctorate degrees, the social class is presumed to be atleast upper middle class. The packets contained ademographics questionnaire and two Personal Attributes Questionnaires. Results suggest that malepsychologists do exhibit an androgynous gender role inboth professional and personal realms. A great deal ofthe prior literature indicates that androgynoustherapists have more adaptive communication skills and arebetter at assessing and treating their clients. Thisresult is therefore advantageous to therapeuticoutcomes. 相似文献

Use of carbon monoxide breath validation in assessing exposure to cigarette smoke in a worksite population 总被引:2,自引:0,他引:2
Assessed the usefulness of carbon monoxide (CO) breath validation of self-reported smoking status in a large worksite population (N = 4,647). CO assessment was performed as part of a baseline survey procedure. CO levels differed substantially in relation to self-reported smoking status and amount smoked. Correcting for ambient exposure (estimated by mean CO levels among never smokers) produced more satisfactory results than uncorrected CO levels. Striking company differences were observed in mean CO exposures among self-reported never smokers. An unexpected finding was that 17.1% of current smokers reported smoking less than daily. Although the CO measure was excellent in detecting moderate and heavy smokers, it was inadequate in detecting occasional and light smokers. If detection of occasional or lighter smoking is critical to the purposes of the study, the more expensive (but more accurate) cotinine measure is preferred. 相似文献
