Free and informed consent is generally acknowledged as the legal andethical basis for living organ donation, but assessments of livingdonors are not always an easy matter. Sometimes it is necessary toinvolve psychosomatics or ethics consultation to evaluate a prospectivedonor to make certain that the requirements for a voluntary andautonomous decision are met. The paper focuses on the conceptualquestions underlying this evaluation process. In order to illustrate howdifferent views of autonomy influence the decision if a donor's offer isethically acceptable, three cases are presented – from Germany, theUnited States, and India. Each case features a person with questionabledecision-making capacity who offered to donate a kidney for a siblingwith severe renal insufficiency. Although the normative framework issimilar in the three countries, different or sometimes even contraryarguments for and against accepting the offer were brought forward. Thesubsequent analysis offers two explanations for the differences inargumentation and outcome in spite of the shared reference to autonomyas the guiding principle: (1) Decisions on the acceptability of a livingdonor cannot simply be deducted from the principle of autonomy but needto integrate contextual information; (2) understandings of the wayautonomy should be contextualized have an important influence on theevaluation of individual cases. Conclusion: Analyzing the conceptualassumptions about autonomy and its relationship to contextual factorscan help in working towards more transparent and better justifieddecisions in the assessment of living organ donors. 相似文献

The past and current states of research on social comparison are reviewed with regard to a series of major theoretical developments that have occurred in the past 5 decades. These are, in chronological order: (1) classic social comparison theory, (2) fear-affiliation theory, (3) downward comparison theory, (4) social comparison as social cognition, and (5) individual differences in social comparison. In addition, we discuss a number of expansions of research on social comparison as they are currently occurring, and we outline what we see as likely and desirable future directions, including an expansion of areas, methods, and conceptualizations, as well as a stronger focus on cognitive, neuroscientific, and evolutionary aspects of social comparison. 相似文献

The aim of this study was to investigate whether maternal anxiety that is temporary or chronic during the pre‐ and postnatal period predicts infant temperament. Mothers of 2997 infants in a population‐based birth cohort reported levels of pregnancy‐specific anxiety (Pregnancy Outcome Questionnaire) and general anxiety symptoms (Brief Symptom Inventory) prenatal and at 6 months postnatal. Temperament characteristics were assessed by maternal report using the Infant Behavior Questionnaire—Revised when the infants were 6 months of age. Maternal pregnancy‐specific and general anxiety during the pre‐ and postnatal period were all independently associated with perceived infant temperamental difficulties. Chronically high maternal anxiety predicted the highest perceived infant activity level and negative affectivity. These findings show that different forms of maternal anxiety during both the pre‐ and postnatal period are independently related to perceived temperamental problems in infancy. They also emphasize the significance of chronic maternal anxiety for infant mental health. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

The present ERP study investigated effects of subliminal emotional words on preference judgments about subsequent visual target stimuli (paintings, portraits). Each target was preceded by a masked 17-ms emotional adjective. Four classes of prime words were distinguished according to the combinations of positive/negative valence and high/low arousal. Targets were liked significantly more after positive-arousing primes (e.g., happy), relative to negative-arousing (brutal), positive-nonarousing (mild), and negative-nonarousing primes (lazy). In the target ERP, amplitude of right-hemisphere positive slow wave was increased after positive-arousing compared to negative-arousing primes. Evaluative priming effects on judgments and ERPs were more pronounced in high state-anxious participants. The results suggest that (1) there is indeed affective/semantic processing of unconscious words, (2) evaluative priming operates relatively late during target processing, (3) to be effective, prime words need to score high on the arousal dimension, and (4) individual differences in state anxiety modulate the susceptibility to subliminal evaluative priming. 相似文献

OBJECTIVE: To determine whether the effect of movie exposure to smoking on adolescent smoking onset is mediated through increased affiliation with peers who smoke. DESIGN: A longitudinal study was conducted with a sample of 5th- 8th graders; persons who were nonsmokers at the baseline assessment (N = 2,614) were followed up 18 months later. Movie exposure to smoking cues was assessed at baseline with a rigorous coding procedure. MAIN OUTCOME MEASURE: A school-based survey and follow-up telephone interview determined whether the participant smoked cigarettes. RESULTS: Longitudinal structural modeling analysis indicated movie-smoking exposure was related to smoking onset both through an indirect effect involving increased affiliation with peer smokers and through a direct effect. The analysis controlled for demographics, parenting style, rebelliousness and sensation seeking, school performance, parental smoking, and sibling smoking; several of these variables also had mediated or direct effects to smoking onset. CONCLUSION: The effect of movie exposure on adolescent smoking onset is attributable in part to a social mechanism. Implications of media effects for prevention are discussed. 相似文献
