This study examined the influences of semantic characteristics of objects in real-world scenes on allocation of attention as reflected in eye movement measures. Stimuli consisted of full-color photographic scenes, and within each scene, the semantic salience of two target objects was manipulated while the objects' perceptual salience was kept constant. One of the target objects was either inconsistent or consistent with the scene category. In addition, the second target object was either smoking-related or neutral. Two groups of college students, namely current cigarette smokers (N=18) and non-smokers (N=19), viewed each scene for 10s while their eye movements were recorded. While both groups showed preferential allocation of attention to inconsistent objects, smokers also selectively attended to smoking-related objects. Theoretical implications of the results are discussed. 相似文献

Although several studies show symptomatic improvements in patients with personality disorders after short-term inpatient psychotherapy, reintegration remains difficult. In this study the effectiveness of a specifically designed reintegration training program is investigated. One hundred twenty-eight patients were randomized to either a reintegration training program aimed at improving general functioning and work resumption, or booster sessions. Outcome measures used were symptom level, work status, absence from and impediments at work. The results showed that compliance in the booster session group was significantly better than in the reintegration training program. The percentage of persons with a paid job increased during the booster sessions from 64 to 87%, but not during the reintegration training (76%). There were no differences in the other outcome measures. We concluded that reintegration training was not more (cost)-effective than booster sessions. Our hypothesis is that continuity of care (same therapists and program) explains the favorable results of the booster sessions. 相似文献

The question whether executive function (EF) deficits in children are associated with conduct problems remains controversial.
Although the origins of aggressive behavior are to be found in early childhood, findings from EF studies in preschool children
with aggressive behavior are inconsistent. The current study aimed to investigate whether preschool children with aggressive
behavior show impairments in EF. From a population-based sample, 82 preschool children who were showing aggressive behavior
as indicated by scores at or above the 93rd percentile on the Aggressive Behavior Scale of the CBCL 1 1/2-5 were selected.
These children with aggressive behavior were matched on IQ to a group of typically developing control children (N = 99). Six neuropsychological tasks were administered to assess set shifting, inhibition, working memory and verbal fluency.
A factor analysis was conducted which yielded one clear factor: inhibition. Aggressive preschool children showed poorer performance
on this inhibition factor than control children and boys performed worse on this factor than girls. This association between
aggressive behavior and inhibition deficits was maintained after controlling for attention problems. In addition, gender differences
in all EFs measured were found with boys exhibiting more impairment in EF than girls. These findings demonstrate that preschool
children with aggressive behavior show impairments in inhibition, irrespective of attention problems. 相似文献

On the basis of personal reminiscences an account is given of Harlow’s role in the development of attachment theory and key
notions of attachment theory are being discussed. Among other things, it is related how Harlow arrived at his famous research
with rhesus monkeys and how this made Harlow a highly relevant figure for attachment theorist Bowlby.
Stephen J. Suomi is Head of the Laboratory of Comparative Ethology at the National Institute of Child Health and Human Development (NICHD) in Bethesda, Maryland. He became well-known for his research on the biobehavioral development of rhesus monkeys and other nonhuman primate species. He authored over 300 published articles in refereed scientific journals and chapters in edited volumes. Among his current interest are the interactions between genetic and environmental factors that shape individual developmental trajectories. Frank C.P. van der Horst is a Ph.D. student and Lecturer at the Centre for Child and Family Studies at Leiden University, The Netherlands. The work presented in this special issue is part of his doctoral thesis on the roots of Bowlby’s attachment theory. The defence of this thesis, titled John Bowlby and ethology: a study of cross-fertilization, is scheduled for early 2009. René van der Veer is Professor of History of Educational Thinking at Leiden University, The Netherlands. His research addresses the work of key educational thinkers such as Gal’perin, Janet, Piaget, Vygotsky, Werner, and Wallon. In a longer study the origin of the idea of the social mind was traced. He is on the Editorial Board of Integrative Psychological and Behavioral Sciences. 相似文献

Psychosocial factors have been shown to play an important role in the aetiology of coronary heart disease (CHD). A strong
association between CHD and socioeconomic status (lower-level education, poor financial situation) has also been well established.
Socioeconomic differences may thus also have an effect on psychosocial risk factors associated with CHD, and socioeconomic
disadvantage may negatively affect the later prognosis and quality of life of cardiac patients. The aim of this study was
to review the available evidence on socioeconomic differences in psychosocial factors which specifically contribute to CHD.
A computer-aided search of the Medline and PsycINFO databases resulted in 301 articles in English published between 1994 and
2007. A comprehensive screening process identified 12 empirical studies which described the socioeconomic differences in CHD
risk factors. A review of these studies showed that socioeconomic status (educational grade, occupation or income) was adversely
associated with psychosocial factors linked to CHD. This association was evident in the case of hostility and depression.
Available studies also showed a similar trend with respect to social support, perception of health and lack of optimism. Less
consistent were the results related to anger and perceived stress levels. Socioeconomic disadvantage seems to be an important
element influencing the psychosocial factors related to CHD, thus, a more comprehensive clarification of associations between
these factors might be useful. More studies are needed, focused not only on well-known risk factors such as depression and
hostility, but also on some lesser known psychosocial factors such as Type D and vital exhaustion and their role in CHD. 相似文献

人与自然和谐的道德基础——古代"天人合一"思想的现代生态伦理启示 总被引:4,自引:0,他引:4
人与自然的和谐有着道德基础。古代的“天人合一”思想为我们从道德的视角研究人与自然的和谐,以及建构现代生态伦理观提供了一定的帮助。从道德的意义上,人与自然的和谐中人是道德主体,承担着全部道德责任,其行为是道德评价的对象。人对自然的适应与改造、尊重与利用是辩证的统一。 相似文献

This study examined whether distinct groups of young adolescents with mainly anxiety or mainly depression could be identified in a general population sample. Latent class analysis was used on self-report ratings of DSM-IV symptoms of anxiety and depressive disorders, because it was hypothesized that these ratings provide a bigger chance to identify distinct groups than parent ratings of symptoms that are poorly associated with DSM-IV. Results from exploratory and confirmatory latent class analysis showed that only very small numbers of young adolescents had mainly anxiety or mainly depressive symptoms. Instead, a five-group model fitted the data best. These five groups contained young adolescents who either had a high, intermediate, or low probability to have comorbid symptoms of anxiety and depression. It was concluded that symptoms of DSM-IV anxiety and depressive disorders co-occur in young adolescents, and that latent class analysis on items that capture also severe symptoms like suicidal thoughts are needed to derive groups with specific comorbidity patterns in a general population sample. 相似文献

Cognitive behavioural conceptualisations of grief propose that negative cognitions and avoidance strategies play a key role in emotional problems after bereavement. In the current study, this assumption was examined. Ninety-seven individuals who had lost a relative less than 5 months ago completed questionnaires tapping background and loss-related variables, negative cognitions (about the self, life, the future, and one's own grief reactions), avoidance, and symptoms of complicated grief (CG) and depression. Of these mourners, 70 people (72%) completed symptom measures again 6 months later at T2 (7-10 months after the loss), and 60 (62%) completed symptoms measures still 9 months later at T3 (16-19 months after the loss). Among other things, results showed that all four cognitive variables and the avoidance variable were strongly associated with concurrent and prospective symptom levels, even when the influence of relevant background/loss-related variables was controlled. In addition, independent of initial symptom levels, most of the cognitive variables predicted later CG and depression. The avoidance variable only predicted additional variance in depression at T3 beyond T1 symptom levels. Findings indicate that negative cognitions are important in emotional problems after bereavement and that the role of avoidance in the development of these problems needs further scrutiny. 相似文献
