Previous studies have found that a stressful observational context challenges the mother-child relationship, thus highlighting negative interactive behavior. However, the impact of observational context has only been investigated in infants and preschoolers without specifically using the Emotional Availability Scales. Nor have they explored whether the association of mother-child interaction with children’s emotional or behavioral problems depends on the observational context. We observed 140 mothers and their five to 12-year-old children in non-stressful free play and in a stressful task context. In general, dyads showed higher emotional availability in the task context compared to the free play. Specifically, mothers showed higher levels of Sensitivity, Structuring and Nonhostility, but lower levels of Nonintrusiveness during the task compared to the free play context; children showed higher levels of Responsiveness during the task than during free play. After controlling for dyadic stress, contextual effects decreased for all dimensions of emotional availability. The association of mother-child interaction with child problem behavior depended on the observational context. Specifically, we found maternal emotional availability during free play to be more strongly associated with child problem behavior than during the stressful task; however, emotional availability of the child was more strongly associated with problem behavior when obtained during the task. We conclude that context impacts on mother-child interactive behavior and also on the association of mother-child-interaction and child behavior. Stress is a relevant contextual factor influencing mother-child interactive behavior.  相似文献

A robust finding in social psychology is that people judge negative events as less likely to happen to themselves than to the average person, a behavior interpreted as showing that people are "unrealistically optimistic" in their judgments of risk concerning future life events. However, we demonstrate how unbiased responses can result in data patterns commonly interpreted as indicative of optimism for purely statistical reasons. Specifically, we show how extant data from unrealistic optimism studies investigating people's comparative risk judgments are plagued by the statistical consequences of sampling constraints and the response scales used, in combination with the comparative rarity of truly negative events. We conclude that the presence of such statistical artifacts raises questions over the very existence of an optimistic bias about risk and implies that to the extent that such a bias exists, we know considerably less about its magnitude, mechanisms, and moderators than previously assumed.  相似文献

Of 1,409 eligible children aged 6-13 years in grades 1 to 7 who were randomly selected from a national sample of Norwegian schools, 858 participated in the present study (60.9%). The sample was stratified by school centrality, region and size of grade cohort. The teachers assessed their children's academic performance, adaptive school functioning, and levels of emotional/behavioral problems using the 2001 version of the Teacher Report Form (TRF). Only one child was randomly selected from each grade cohort. Girls had significantly higher scores than boys in the Working Hard, Appropriate Behavior, Learning, and Total Adaptive Functioning domains. For girls, only the Working Hard domain was of medium effect size. While boys had significantly higher scores than girls on Attention, Thought Problems, Rule-Breaking, Aggression, Externalizing Problems and Total problems, only Attention Problems showed a medium effect size. Significant sex by age interaction effects were also found for Rule-Breaking, Externalizing, Internalizing, Anxious-Depressed and Total Problems. In all these comparisons, 10-13-year-old boys had significantly higher scores than 6-9-year olds, while girls had similar problem levels across age groups. Our mean Total Problems score (17.2) was lower than the grand mean (21.6) reported in a multi-country comparison but higher than in another Norwegian large-scale survey. Overall, our findings indicate that teachers in Scandinavia report, just as do parents, relatively low levels of emotional/behavioral problems among school-aged children.  相似文献

Prior research has found entrepreneurs to experience significantly higher job control and job demands compared with employees. This suggests that entrepreneurs have so‐called active jobs and thus may benefit from positive health consequences. The present research compared entrepreneurs' health with employees' health in a national representative sample with regard to the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD‐10) diagnoses of somatic diseases, the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM‐IV) diagnoses of mental disorders, blood pressure, well‐being (life‐satisfaction) as well as behavioural health indicators (sick days, physician visits). Entrepreneurs showed significantly lower overall somatic and mental morbidity, lower blood pressure, lower prevalence rates of hypertension, and somatoform disorders, as well as higher well‐being and more favourable behavioural health indicators. The results are discussed with regard to the active job hypothesis and recommendations for future research are provided.  相似文献

Is the wrongness of an action a reason not to perform it? Of course it is, you may answer. That an action is wrong both explains and justifies not doing it. Yet, there are doubts. Thinking that wrongness is a reason is confused, so an argument by Jonathan Dancy. There can’t be such a reason if ‘?-ing is wrong’ is verdictive, and an all things considered judgment about what (not) to do in a certain situation. Such judgments are based on all the relevant reasons for and against ?-ing. If that ?-ing is wrong, while being an all things considered verdict, would itself be a reason, it would upset the balance of reasons: it would be a further reason which has not yet been considered in reaching the verdict. Hence, the judgment wasn’t ‘all things considered' after all. I show that the argument against wrongness being a reason is unsuccessful, because its main assumption is false. Is main assumption is that a consideration which necessarily does not affect the balance of reasons is not a reason. I also argue that there can be no deontic buck-passing account.  相似文献

Treatments for eating disorders, in particular for people with anorexia nervosa, have often been adaptations of therapies designed for other conditions. Indeed, there is a move advocating the use of a transdiagnostic treatment approach in which general module based treatments are mixed together as needed rather than using a specific anorexia nervosa targeted strategy. The outcome of treatment is relatively poor, especially for those who for some reason do not have the benefit of an expert form of early intervention for anorexia nervosa. Technological advances in the neurosciences and genetics have radically altered how eating disorders and in particular anorexia nervosa have been conceptualised. In this paper we describe evidence that suggests that key aspects of the social information processing network both the cognitive and affective elements may be anomalous in people with anorexia nervosa. This has implications for models of treatment which can be tailored more directly to these causal and or maintaining factors. We describe the Maudsley method of working with adults with anorexia nervosa which has integrated these elements. This treatment approach includes working with the individual to develop a more flexible and holistic cognitive style with greater emotional intelligence. This is supplemented with work with the families to interrupt interactions that either accommodate to or aggravate the symptoms. Thus we are now in the position to understand and work to change how people with anorexia nervosa think and behave rather than focusing on what people think and say they do. Our prediction is that treatments that focus more directly on aetiology such as the intrapersonal and interpersonal maintaining factors will improve outcome.  相似文献

Logic-based XML data integration: a semi-materializing approach   总被引:1,自引:0,他引:1  
We first describe the approach to XML data integration in the XPathLog/LoPiX project that uses a warehouse strategy. We show that the DOM model and the XML Query Data Model are not suitable for this task since the integrated database is not necessarily a tree, but a set of overlapping (original and integrated) trees. The problem is solved by using a node-labeled graph-based data model, called XTreeGraph, for the internal XML database that represents multiple, overlapping XML trees, or tree views.In the second part, we return to the standard XML data model—by still keeping the overlapping tree idea by “simulating” it: The data is internally represented by XML where the “overlayed” resulting tree is represented by XLink elements that refer to the original sources. By using a logical, transparent data model for XLinks as investigated in [May, in: 11th WWW Conference, 2002], all queries behave as stated against the XTreeGraph. The use of links for partial materialization also turns the approach from a warehouse approach into a mixed approach that combines the advantages of the warehouse approach and of the virtual approach. The approach is again illustrated by using XPathLog as data integration language.  相似文献

Disturbances of body-images in women with anorexia and bulimia nervosa are described at the behavioral, perceptional and affective-cognitive level. The disturbances of body image, which are often accompanied by personality-structural deficits and have a decisive influence on the course of disease, can be reached only in part by verbal forms of therapy. Considering these facts, we present an integrative clinical procedure in which the application of body-related therapy modules play a central role in supplement to cognitive-behavioral and psychodynamic forms of therapy. Process-oriented body-perception therapy in an individual setting and a communicative movement group therapy are used and their relevance to the in-patient therapy process examined from the patient’s point of view. The study reveals a high value of body-psychotherapy, wherebydifferences were observed between anorexia (15) and bulimia (27) patients in the course of the process. The results suggest an indication for the application of combined individual and group body-psychotherapy for hospitalized anorexia patients. A communicative body therapy in group form is also very important in the in-patient treatment of bulimia patients, but there is a differential indication with regard to individual body therapy.  相似文献

Studies investigating changes in functional cerebral asymmetries (FCAs) with hormonal fluctuations during the menstrual cycle in young women have led to controversial hypotheses about an influence of estrogen (E) and/or progesterone (P) on FCAs. Based on methodical, but also on principal problems in deriving conclusions about hormone effects from correlational designs, the present study investigated hemispheric asymmetries in postmenopausal women, who received hormone replacement either with E alone (E group, n = 32), an E–P combination (E–P group, n = 29) or no hormone substitution (control group, n = 31). Speed and accuracy of responses to a word- and a face decision task, both presented laterally by means of the visual half field technique, were assessed. The control group showed the typical pattern of hemispheric asymmetry with more correct responses to verbal stimuli presented in the right visual field (RVF) and to face stimuli presented in the left visual field (LVF). A hormone-effect was demonstrable only for the verbal task, in which the E group showed an enhanced performance of the right hemisphere (LVF). The E–P group showed no significant differences to the control group or the E group. The results suggest a role of E in the modulation of FCAs at least with regard to verbal processing.  相似文献
