Research has shown that a disturbed capacity to relate to others is a key feature of borderline personality disorder (BPD; e.g., Bender & Skodol, 2007; Gunderson, 2007). However, few attempts have been made to determine if and how this disturbance translates into identifiable core interpersonal patterns. This study investigated the relationship patterns of 68 patients presenting with BPD. Vignettes of interpersonal interactions spontaneously reported by participants were rated using the Core Conflictual Relationship Theme (CCRT; Luborsky & Crits-Christoph, 1990) method. Results of a factor analysis revealed six patterns of interactions: (1) interactions involving the ego ideal; (2) dependent-depressive interactions; (3) receptive interactions; (4) passive-submissive interactions; (5) successful interactions; and (6) sadomasochistic interactions. The clinical implications of these findings are discussed.  相似文献

Training for coping with stress as the core instrument of prevention of stress-related disorders at the individual level is characterized within the framework of prominent theoretical concepts of stress and derived from these. Response-focused, situation-focused and relational definitions of stress as well as the main results of stress research are described. The cognitive-transactional stress theory and the concept of coping are then outlined in their main features and control of stressor exposition, problem-focused coping, cognitive reappraisal, emotion-focused coping and mobilization of social support are characterized as main targets and modes of intervention in coping skills group programs. General aspects of such programs, selected findings on effectiveness and methodological considerations regarding the evaluation are then depicted. It is concluded that training of individual coping skills should be supplemented by preventive intervention at the institutional or organizational level.  相似文献

Mother's open-ended questions and elaborative statements during reminiscing were analysed for their content (child agency, co-agency, non-social, and social context) in three cultural contexts. Participants were 115 mothers and their 4-year-old children: 35 dyads from Berlin, Germany, 42 from Stockholm, Sweden, and 38 from Tallinn, Estonia. Across samples the most prominent content was talk about non-social context followed by co-agency and child agency. Tallinn mothers asked the children to talk about themselves, and Berlin mothers asked the children to talk about themselves together with other people, more frequently than they talked about these contents themselves. The content was related to the cultural orientations of mothers assessed through questionnaires: the Berlin mothers whose independence/ interdependence ratio was higher talked less about other people and asked the children fewer questions about other people; the Stockholm mothers with a higher independence/interdependence ratio talked more about child agency. In Tallinn both correlations existed on a trend level. The results are discussed in the light of common conversational practices and mothers' orientation to independence and interdependence in these cultural contexts.  相似文献

In this study, effects of weaning on behavioral and physiological stress parameters in young horses (foals) were determined. Foals were weaned either simultaneously without the presence of adult horses (group A, n?=?6), or in the presence of two adult females familiar but unrelated to the foals (group B, n?=?5), or weaned consecutively by removing two mother horses per day (group C, n?=?6). Behavior, locomotion, salivary cortisol concentration, beat-to-beat (RR) interval, heart rate variability (HRV) and weight were determined. Group A foals lost weight for 2 days (mean?±?SEM) -?8.3?±?1.6?kg, p?相似文献

Current GPS-based mobile navigation assistance systems support wayfinding, but they do not support learning about the spatial configuration of an environment. The present study examined effects of visual presentation modes for navigation assistance on wayfinding accuracy, route learning, and configural learning. Participants (high-school students) visited a university campus for the first time and took a predefined assisted tour. In Experiment 1 (n = 84, 42 females), a presentation mode showing wayfinding information from eye-level was contrasted with presentation modes showing wayfinding information included in views that provided comprehensive configural information. In Experiment 2 (n = 48, 24 females), wayfinding information was included in map fragments. A presentation mode which always showed north on top of the device was compared with a mode which rotated according to the orientation of the user. Wayfinding accuracy (deviations from the route), route learning, and configural learning (direction estimates, sketch maps) were assessed. Results indicated a trade-off between wayfinding and configural learning: Presentation modes providing comprehensive configural information supported the acquisition of configural knowledge at the cost of accurate wayfinding. The route presentation mode supported wayfinding at the cost of configural knowledge acquisition. Both presentation modes based on map fragments supported wayfinding. Individual differences in visual-spatial working memory capacity explained a considerable portion of the variance in wayfinding accuracy, route learning, and configural learning. It is concluded that learning about an unknown environment during assisted navigation is based on the integration of spatial information from multiple sources and can be supported by appropriate visualization.  相似文献

Research suggests a central role of executive functions for children's cognitive and social development during preschool years, especially in promoting school readiness. Interventions aiming to improve executive functions are therefore being called for. The present study examined the effect of a small group intervention implemented in kindergarten settings focusing on basic components of executive functions, i.e., working memory, interference control and cognitive flexibility. A total of 135 children enrolled in Swiss prekindergarten (5‐year‐olds) and kindergarten (6‐year‐olds) were involved. Results revealed that the small group intervention promoted gains in all three included components of executive functions: prekindergarten children substantially improved their working memory and cognitive flexibility processes, whereas significant training effects were found for the kindergarten children in interference control. Implications of these findings for early intervention programs and for tailoring preschool curricula are discussed, particularly with respect to children's school readiness.

The effects of emotional stimulus content on attention are well-known. In contrast, the impact of emotional information on higher executive control functions is undetermined. To elucidate the role of negative emotion in cognitive control, 56 adult female participants performed a combined working memory and response inhibition task, with threat-relevant (spider and snake) and neutral (flower and mushroom) stimuli. Threat-relevant stimuli impaired performance, by causing prolonged response times to working memory items and increased response inhibition error rate relative to neutral stimuli. The impaired response inhibition was only evident when threat-relevant stimuli co-occurred with working memory matches, in line with a common resource pool view of executive functions and emotion processing. Individual differences in reported fear of spiders were associated with differences of inhibitory control, while fear of snakes was associated with impaired overall accuracy on working memory trials. The results are discussed in relation to the dual-competition framework for interaction between executive functions and emotion (Pessoa, 2009).  相似文献

Abstract

The growing ill-health in Sweden is related to the crisis of the welfare state and to globalization and the expansion of a new virtual reality affecting the conceptualization of time and space, as well as to wider areas of human interaction, thinking, and ethical judgment. Fear and anxiety are emotional states of mind that have widespread effects on an individual level as well as on the whole of society.  相似文献
