Historical accounts of the social sciences have too often accepted local or national institutions as a self-evident framework of analysis, instead of considering them as being embedded in transnational relations of various kinds. Evolving patterns of transnational mobility and exchange cut through the neat distinction between the local, the national, and the inter-national, and thus represent an essential component in the dynamics of the social sciences, as well as a fruitful perspective for rethinking their historical development. In this programmatic outline, it is argued that a transnational history of the social sciences may be fruitfully understood on the basis of three general mechanisms, which have structured the transnational flows of people and ideas in decisive ways: (a) the functioning of international scholarly institutions, (b) the transnational mobility of scholars, and (c) the politics of trans-national exchange of nonacademic institutions. The article subsequently examines and illustrates each of these mechanisms.  相似文献

The development of three aspects of selective attention was studied in 451 Dutch schoolchildren attending second to sixth grade. Selective attention was measured with the d2 Test of attention. The largest age differences were found for processing speed that continued to improve until the sixth grade. Impulsivity, as measured by the percentage of errors of commission, decreased until the fourth grade. Inattention, measured by the percentage of errors of omission, was stable in all grades. Processing speed and impulsivity were correlated with the score on the Attention Problems subscale of the Child Behavior Checklist. These results imply that selective attention continues to develop, at least, until the end of elementary school. The findings are support for a step-wise model of cognitive development (P. Anderson, 2002).  相似文献

This study examines international adoptees and factors associated with searching for birth parents. A total of 1,417 international adoptees in The Netherlands, aged 24 to 30 years, were divided into 4 groups: uninterested nonsearchers, interested nonsearchers, searchers, and reunited searchers. In total, 32% of adoptees had searched. Although the majority of searchers were well-adjusted, they had more problems--mainly internalizing problems--than uninterested nonsearchers. These problems, however, were not caused by the search itself. It is concluded that searching is the product of natural curiosity influenced by external factors such as the divorce of adoptive parents and the options for searching.  相似文献

Separation anxiety and social phobia are intertwined to a considerable degree, and high comorbidity rates have been reported. The present study used latent class analysis (LCA) to investigate if classes of children and adolescents with-simultaneously-high rates of separation anxiety and low rates of social anxiety symptoms, or vice versa, could be identified. Eight- to 18-year-olds from a large general population (n=1000) and referred sample (n=735) were assessed with the Multidimensional Anxiety Scale for Children (MASC). With LCA, a separate class of referred 8-11-year-old children with high separation anxiety scores, and simultaneously lower social anxiety scores was identified, next to a class of children with high scores on separation anxiety and social anxiety. In the other groups (referred 12-18-year-olds and children and adolescents from the general population), a class with individuals who specifically scored high on separation anxiety could not be revealed. The results indicated that separation anxiety represents a different construct than social anxiety in referred children (but not in referred adolescents or in the general population). It can be concluded that, in referred children, research regarding etiology and treatment outcome of anxiety symptoms should be aimed specifically at separation anxiety and social anxiety, instead of just investigating a broader anxiety dimension.  相似文献

The author argues that objections to involving the infant in a relationship with an analyst have led psychoanalysts to overlook the possibility that the interaction between the infant and the analyst may be able to activate and retrieve those parts of the infant's inner world that have been excluded from containment and be conducive to a vitalisation of the emotional disturbance that can then become worked through in the mother-infant relationship. As long as the infant's ego is weak, the infant and the mother have a unique flexibility that enables them to repair disturbances in their relationship when the emotional container-contained link is (re-)established. Based on the assumptions (1) that a relationship can be established between the infant and the analyst, (2) that the infant has a primordial subjectivity and self as base for intersubjectivity and the search for containment, (3) that the infant has an unique flexibility in changing representations of itself and others that comes to an end as the ego develops, and (4) that the infant is able to process aspects of language, three cases, at the ages of 6, 18 and 20 months, are presented to illustrate what is considered to be a novel approach to work with infants.  相似文献

We investigated the relative importance of convexities (protrusions) and concavities (indentations) for the perception of shape. On the one hand, it has been suggested that convexities determine the shape of an object, whereas concavities merely act as “perceptual glue” between the convexities. On the other hand, it has been argued that concavities are more salient than convexities. We show that participants find it easier to detect asymmetry in a 2-D silhouette when there is a mismatch between the shapes of convexities on either side of the axis of symmetry than when there is a mismatch between the shapes of concavities. This is the case even when the concavities are closest to the axis of symmetry, and despite the usual bias toward this axis in symmetry perception. We suggest that the actual shape of concavities is less important in symmetry perception, because the main role of concavities is to act as part boundaries in the representation of the shape of objects.  相似文献

Fear of movement/(re)injury is assumed to contribute to the development and maintenance of chronic low back pain (CLBP) in a subgroup of patients. Studying fear of movement/(re)injury with implicit attitude measures, without the awareness of the patient, might be a valuable addition to self-report questionnaires. The aims of the current study were to investigate whether CLBP patients demonstrate more implicit fear of movement/(re)injury than healthy controls, and whether 2 implicit measures are related to each other, and to an explicit self-report measure of fear of movement/(re)injury. A group of 66 CLBP patients and 30 healthy controls took part in this study. In addition to self-report questionnaires, fear of movement/(re)injury was implicitly assessed by the Extrinsic Affective Simon Task (EAST) and the Go-No-Go-Association Task (GNAT) that aimed to determine the association between back-stressing movements and the evaluation "threatening". On both implicit tasks it was found that neither CLBP patients nor healthy controls demonstrated implicit fear of movement/(re)injury, and that CLBP patients did not differ from healthy controls in their level of implicit fear of movement/(re)injury. In general, no associations were found between the EAST and the GNAT, or between implicitly measured and self-reported fear of movement/(re)injury. One major caveat in drawing inferences from these findings is the poor reliability of these implicit measures. Research towards the psychometric properties of these measures should first be expanded before modifying, and applying, them to more complex domains such as fear of movement/(re)injury.  相似文献

Long-term follow-up studies of long-term psychoanalytically oriented psychotherapy or psychoanalysis are extremely rare, and few have focused on the post-treatment process itself. In the Stockholm Outcome of Psychoanalysis and Psychotherapy project, one of the results was that patients in psychoanalysis continued to improve after termination to a higher degree than patients in long-term psychotherapy. In this study 20 patients selected from the project were interviewed on two occasions, one and two years after termination, in order to explore how they described their post-treatment processes. The interviews were studied qualitatively using a multiple case study design, and categories of different types of post-treatment development were created from these case studies. Results indicate that the variation within treatment groups is large, and that development may continue in several ways after termination. The most striking difference between psychoanalysis and psychotherapy was not, as hypothesized, in the self-analytic function, but in various self-supporting strategies described by former analysands but not by former psychotherapy patients. However, only self-analysis was significantly correlated with post-termination improvement across both treatments. Three patients improving after termination and three deteriorating are described in detail as illustrations. Some methodological constraints of the design limit the generalizeability of results.  相似文献

Type D personality, a synergy between negative affectivity and social inhibition, has established itself as a serious risk factor for morbidity and mortality in patients suffering from cardiovascular disease. In this review, we summarize studies on the validity of the assessment methods of Type D, emphasizing its role as an independent vulnerability factor in the progression of cardiovascular disease. We further present evidence on the physiological characteristics that accompany the 2 psychological traits negative affectivity and social inhibition and may mediate the relation between personality and prognosis in heart disease. Further research needs to determine the mechanisms by which Type D affects the course and outcome of cardiovascular disease as well as how Type D patients may benefit from psychosocial intervention.  相似文献
