Are there distinctly European values in bioethics, and if there are, what are they? Some Continental philosophers have argued that the principles of dignity, precaution, and solidarity reflect the European ethos better than the liberal concepts of autonomy, harm, and justice. These principles, so the argument goes, elevate prudence over hedonism, communality over individualism, and moral sense over pragmatism. Contrary to what their proponents often believe, however, dignity, precaution, and solidarity can be interpreted in many ways, and it is not clear which reading would, or should, be favored by popular opinion. It is therefore dangerous to think that any one understanding of "European", or any other, values could be legitimately imposed on those who have different ideas about morality in health care and related fields. Bioethical principles should be employed to promote discussion, not to suppress it.  相似文献

The study set out to examine parents' evaluations of the school they had attended and the role of these evaluations in the formation of parental attitudes towards education. A group of vocationally educated (N = 343) and a group of academically educated (N = 231) parents were asked to think back to their primary school days and evaluate the functioning of their school; they were also requested to indicate their opinions on a set of attitude statements and to predict their preschool-aged child's future direction in secondary education. The parents' evaluation of their schools averaged at satisfactory, with the highest grade given to the quality of the instruction and the lowest grades to the giving of encouragement and the capability of taking individual needs into consideration. The school evaluations were organized by the school generation and, in particular, by the educational position of the subject, so that those parents who had gone to the (new) comprehensive school and those who were university-educated gave more positive evaluations of their schools than did those who had gone to the (old) folk school and those who were vocationally educated. The critical educational attitudes corresponding to the educational position of the academically educated parents were enhanced if their evaluation of their own school was negative, whereas the positive educational attitudes corresponding to the educational position of the vocationally educated parents were enhanced if their evaluation of their own school was positive. With the vocationally educated parents, their school evaluation also organized their prediction of their child's secondary education: a positive evaluation raised and a negative evaluation lowered the likelihood of vocational education as the predicted alternative.  相似文献

Cross-situational stability in parents' emotional warmth and guidance was studied by observing parents (N = 77, M age = 38 years) with their school-aged child in 2 dyadic problem-solving situations and in a family discussion concerning a moral dilemma. The observational data were coded by independent observers using dimensional ratings and dichotomous frequency counts as the 2 coding procedures. These procedures yielded a similar pattern of findings. Parents tended to behave consistently across situations, although the type of situation did affect the amount of emotional warmth and guidance manifested by the parent. Stability was further analyzed by means of structural equation modeling to test whether variance in parents' emotional warmth and guidance across situations was attributable to a generalized parenting style factor. A Parenting Style factor was identified that reflected the parents' child-centeredness; this factor explained, in part, parental behavior within each situation, although contextual factors also contributed to situation-specific variations from task to task.  相似文献

Four experiments explored how readers use temporal information to construct and update situation models and retrieve them from memory. In Experiment 1, readers spontaneously constructed temporal and spatial situation models of single sentences. In Experiment 2, temporal inconsistencies caused problems in updating situation models similar to those observed previously for other dimensions of situation models. In Experiment 3, merely implied temporal order information was inferred from narratives, affecting comprehension of later sentences like explicitly stated order information. Moreover, inconsistent temporal order information prevented the creation and storage in memory of an integrated situation model. In Experiment 4, a temporal inconsistency increased processing time even if readers were unable to report the inconsistency. These results confirm the significance of the temporal dimension of situation models.  相似文献

Visual perception in 'low vision'   总被引:1,自引:0,他引:1  
Hyvärinen L 《Perception》1999,28(12):1533-1537
'Low vision' has an international classification as an impairment of vision that is defined by loss of visual acuity and the size of the visual field. Functional classification that would depict capability to use vision in different activities has not yet been agreed upon. Abnormal visual information leads to changes in visual perception, and brain-damage-related visual impairment may alter or prevent one or several cognitive visual functions. Abnormal visual perception opens a window into brain mechanisms that the psychophysicists otherwise do not have. Together with clinicians, psychophysicists can help visually impaired persons to understand the nature of their disability by thoroughly studying the nature of the altered image and the profile of cognitive visual functions.  相似文献

Motor activity during encoding of verbal information has been suggested to reduce age differences in episodic memory. Here we examined memory for sentences encoded with enactment (SPTs, subject-performed tasks) or without enactment (VTs, verbal tasks) in a population-based sample consisting of 10 groups ranging in age from 35 to 80 years (N = 1000). Memory performance was assessed by immediate free- and category-cued recall. Degree of clustering was measured by the adjusted ratio of clustering score. Recall of cognitive activities served as a complementary measure of memory for performed tasks. Sentence recall showed a gradual decline across age, of about the same magnitude for SPTs and VTs, in both free and cued recall. Clustering in free recall was higher for SPTs than for VTs, but there were no age differences in clustering. A pattern of gradual decline from age 35 was observed also in activity recall, regardless of whether the activities involved motor activity or not. Across the memory measures, differences in education accounted for all of the age-related variance in performance among the younger (35-55 years) but not the older groups (60-80 years), suggesting that genuine aging effects in these measures are more prominent in old age. Together, the results indicate that age differences in episodic memory, in line with most, if not all, types of encoding support, generalize across the performed/non-performed distinction.  相似文献

Decision makers typically overweight small probabilities and underweight large probabilities. However, there are recent reports that when probability is presented in the form of relative frequencies, this typical pattern reverses. We tested this hypothesis by comparing decision making in two tasks: In one task, probability was stated numerically, and in the other task, it was conveyed through a visual representation. In the visual task, participants chose whether a "stochastic bullet" should be fired at either a large target for a small reward or a small target for a large reward. Participants' knowledge of probability in the visual task was the result of extensive practice firing bullets at targets. In the classical numerical task, participants chose between pairs of lotteries with probabilities and rewards matched to the probabilities and rewards in the visual task. We found that participants' probability-weighting functions were significantly different in the two tasks, but the pattern for the visual task was the typical, not the reversed, pattern.  相似文献

Deficits in executive functioning and working memory associated with frontal lobe dysfunction are prominent in depression and work-related long-term sick leave (LTSL). This study used functional magnetic resonance imaging (fMRI) to investigate potential differences in brain activation patterns in these conditions. In addition, the function of the hypothalamic-pituitary-adrenal (HPA) axis was examined and compared between groups. Since there is a clear overrepresentation of women in these diagnostic groups, and to ensure a more homogenous sample population, only women were included. To examine the neural correlates of relevant cognitive processes in patients on sick leave >90 days due to work-related LTSL, recently diagnosed patients with major depression Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV criteria, untreated), and healthy controls (n?=?10, each group), a 2-back working memory task and a visual long-term memory task were administered during fMRI scanning. HPA axis functioning was investigated using a diurnal curve of saliva cortisol and a dexamethasone suppression test. Task performance was comparable among the three groups. Multivariate image analysis revealed that both memory tasks engaged a similar brain network in all three groups, including the prefrontal and parietal cortex. During the 2-back task, LTSL patients had significant frontal hypoactivation compared to controls and patients with depression. Saliva cortisol measurements showed a flattening of the diurnal rythmicity in LTSL patients compared to patients with depression and healthy contols. Taken together, these findings indicate that work stress-related LTSL and major depression are dissociable in terms of frontal activation and diurnal cortisol rhythmicity.  相似文献

Induction of lucid dreams: A systematic review of evidence   总被引:1,自引:0,他引:1  
In lucid dreams the dreamer is aware of dreaming and often able to influence the ongoing dream content. Lucid dreaming is a learnable skill and a variety of techniques is suggested for lucid dreaming induction. This systematic review evaluated the evidence for the effectiveness of induction techniques. A comprehensive literature search was carried out in biomedical databases and specific resources. Thirty-five studies were included in the analysis (11 sleep laboratory and 24 field studies), of which 26 employed cognitive techniques, 11 external stimulation and one drug application. The methodological quality of the included studies was relatively low. None of the induction techniques were verified to induce lucid dreams reliably and consistently, although some of them look promising. On the basis of the reviewed studies, a taxonomy of lucid dream induction methods is presented. Several methodological issues are discussed and further directions for future studies are proposed.  相似文献

Using two clinical samples of patients, the presented studies examined the construct validity of the recently revised Anxiety Sensitivity Index-3 (ASI-3). Confirmatory factor analyses established a clear three-factor structure that corresponds to the postulated subdivision of the construct into correlated somatic, social, and cognitive components. Participants with different primary clinical diagnoses differed from each other on the ASI-3 subscales in theoretically meaningful ways. Specifically, the ASI-3 successfully discriminated patients with anxiety disorders from patients with nonanxiety disorders. Moreover, patients with panic disorder or agoraphobia manifested more somatic concerns than patients with other anxiety disorders and patients with nonanxiety disorders. Finally, correlations of the ASI-3 scales with other measures of clinical symptoms and negative affect substantiated convergent and discriminant validity. Substantial positive correlations were found between the ASI-3 Somatic Concerns and body vigilance, between Social Concerns and fear of negative evaluation and socially inhibited behavior, and between Cognitive Concerns and depression symptoms, anxiety, fear of negative evaluation, and subjective complaints. Moreover, Social Concerns correlated negatively with dominant and intrusive behavior. Results are discussed with respect to the contribution of the ASI-3 to the assessment of anxiety-related disorders.  相似文献
