Emotion dysregulation in Borderline Personality Disorder (BPD) is characterized by high baseline negative intensity, high reactivity, and slow return to baseline. Patients with BPD often engage in self-injurious behavior because it leads to immediate relief of stress levels. We aimed to assess stress regulation as well as the influence of tissue damage on subjective (aversive tension) and objective (heart rate) stress correlates in BPD. In 14 unmedicated patients with BPD and 18 healthy controls, a stress induction was followed by an incision into the forearm conducted by an investigator. For aversive tension, we found elevated baseline levels as well as slower return to baseline in BPD. In controls, incision resulted in a short-term increase of aversive tension, whereas tension and heart rate decreased in the BPD group. Our preliminary results support the hypothesis that tissue damage may play a role in disturbed stress regulation in BPD. 相似文献

Memory updating is the ability to select and update relevant information and suppress no-longer-relevant data. The few studies in this area, targeting mainly the verbal domain, have investigated and confirmed an age-related decline in working memory updating ability (De Beni & Palladino, 2004; Van der Linden, Bredart, & Beerten, 1994). The present research examines the ability of younger and older adults to update information in verbal and visuo-spatial running memory tasks. Results showed that the participants' performance was higher in the verbal than in the visuo-spatial task. Nonetheless, independently of the task domain, an age-related decline in updating performance was found. Moreover, analysis of serial positions suggested that, in the updating procedure, the participants were not attempting to actively maintain items, preferring to adopt a low-effort, "recency-based" strategy. The use of this type of strategy is more evident in older participants, as shown in both the accuracy performance and the proportion of intrusion errors. 相似文献

Counseling studies have shown that increasing experience is not always associated with better judgments. However, in such studies performance is assessed against external criteria, which may lack validity. The authors applied the Cochran–Weiss–Shanteau (CWS) index, which assesses the ability to consistently discriminate. Results showed that novice counselors performed almost on the same level as very experienced counselors. The authors thus replicated earlier findings with a novel approach: applying an internal coherence criterion. 相似文献

Recent literature has focused on the relation between childhood teasing and adulthood psychopathology, with the majority of this work dependent on a single measure, the Teasing Questionnaire-Revised (TQ-R; Storch et al. Journal of Anxiety Disorders 18:681–694, 2004). However, the factor structure and reliability of the TQ-R requires further examination. The present investigation reevaluated the factor structure of the TQ-R in two large samples. In Study 1, three previous factor models were investigated through confirmatory factor analyses (CFAs) in a large clinical sample. Due to their poor fit, exploratory factor analyses (EFAs) were used to investigate alternative factor models. In Study 2, the factor structure of the previous models and new models from Study 1 EFAs were investigated through CFAs and estimates of internal consistency in a large college sample. Together, these findings provided the most support for a new 21-item five factor model, identified in the Study 1 EFAs and supported by the Study 2 CFAs, with the content of the teasing subscales consistent with the constructs of anxiety, appearance, academics, weight, and height. 相似文献

Standard interventions, such as antidepressive medication or psychotherapy, show only medium effect sizes in the reduction of depressive symptomatology. In addition, medication has problematic and not well accepted side-effects therefore it seems reasonable to look for alternative, cost-effective, easily available treatments which show no side-effects. A large number of studies have demonstrated similar neurophysiological effects of sport as antidepressants or psychotherapies but the crucial question remains unanswered: does sport show antidepressive effects by alleviating depressive symptomatology? Some randomized, controlled studies and all available recent meta-analysis addressing this question are reviewed. This review concludes that randomized control trials including sport activities have similar positive effect sizes as psychotherapy or antidepressant studies. The pre-post effects are in the medium to high range. Such a conclusion is jeopardized by a limited number of methodolically sound studies. It is too early to make evidence-based recommendations about the antidepressive effect of sport. Currently, it can only be speculated about moderators and mechanisms mediating outcome. 相似文献

Non‐standard work schedules involve work outside the Monday–Friday daytime hours. Although research has heavily studied the health and family effects of such schedules, few studies have investigated their relationship to retention. We draw from Maertz and Campion's discussion of motivational forces that influence turnover to propose that employees on non‐standard schedules are more likely to quit their employer because of general job dissatisfaction and because of normative pressures from family and/or friends. Specifically, we hypothesized that employees on day shifts or weekday only schedules would remain with their employer longer than those who work on nonday shifts or on the weekends. We also hypothesized that perceived employment mobility would moderate the effects of non‐standard schedules on retention length. Hypotheses were tested among 3,178 retail employees who worked five different distinct shift arrangements and different weekday/weekend schedules. Cox regression analyses indicated that, as hypothesized, employees working nonday shifts or schedules including weekends remained with their employer for a shorter duration of time than employees not on such schedules. Perceived mobility moderated the schedule–turnover relationship, though not in the hypothesized manner. We discuss the theoretical and practical implications of these findings for work schedule assignment and retention strategies. 相似文献

An increasing number of genetic counselors are moving into non-clinical roles, where their primary duties do not involve direct patient contact. According to the National Society of Genetic Counselors Professional Status Survey in 2010, 23% of counselors working in non-clinical roles identified laboratory or genetic testing as their primary area of work. Using a survey, we identified 43 genetic counselors who work predominately in laboratory settings. The two primary tasks performed by participants, include acting as a customer liaison (95%) and calling out test results (88%). Nineteen participants (44.2%) also reported spending a considerable amount of time signing reports. The most prevalent areas of job satisfaction were support from laboratory directors (76.8%), autonomy (76.7%), interactions with clinicians (69.7%) and interaction with other genetics counselors (67.5%). This is the first study specifically looking at the roles of laboratory genetic counselors, which is an expanding area of genetic counseling. 相似文献

In the present study, introductory-level German students read a simplified story and learned the meanings of new German words
by reading English translations in marginal glosses versus trying to infer (i.e., guess) their translations. Students who
inferred translations were given feedback in English or in German, or no feedback at all. Although immediate retention of
new vocabulary was better for students who used marginal glosses, students who inferred word meanings and then received English
feedback forgot fewer translations over time. Plausible but inaccurate inferences (i.e., those that made sense in the context)
were more likely to be corrected by students who received English feedback as compared with German feedback, providing support
for the beneficial effects of mediating information. Implausible inaccurate inferences, however, were more likely to be corrected
on the delayed vocabulary test by students who received German feedback as compared with English feedback, possibly because
of the additional contextual support provided by German feedback. 相似文献

Naming a picture is slower while ignoring a semantically related versus an unrelated distractor word (semantic picture–word
interference, or PWI). To locate the PWI effect in the word production processing stream (during perceptual encoding, response
selection, or afterward), we used the psychological refractory period paradigm, in which participants identified a tone and
then, at varying SOAs, named a picture while ignoring a semantically related or unrelated word (following Dell’Acqua, Job,
Peressotti, & Pascali, 2007). As in results from the Stroop paradigm (Fagot & Pashler, 1992), we found equivalent PWI effects at short and long SOAs following tone identification in two experiments, indicating that
semantic competition occurs at response selection or later. Our results suggest that it is premature to assume that competitive
selection occurs at multiple levels in the word production system (van Maanen, van Rijn, & Borst, 2009) or that the Stroop and semantic PWI effects are fundamentally different (Dell’Acqua et al., 2007). 相似文献
