Identification and the commitment shift: accounting for gender differences in relationship illusions
Previous work revealed gender differences in relationship illusions. Women, and not men, perceived their dating partners more favorably than their partners' self-perceptions. In two studies, the authors replicated these findings and showed they are moderated by relationship commitment but not by relationship satisfaction. Dating men low in commitment devalued their partners' virtues, whereas those high in commitment exaggerated their partners' virtues compared to their partners' self-perceptions. In contrast, dating women showed relationship illusions irrespective of their commitment. In Study 2, similar results were obtained with relationship-specific identification. Moreover, men's commitment mediated the effect of identification with the relationship. This suggests that gender differences in relationship identities exist at a general level and that men need to identify with and then commit to a specific relationship before they exhibit pro-relationship thinking, which women exhibit as general dispositions. 相似文献

Prevalence rates of trauma and posttraumatic stress disorder (PTSD) were estimated from a probability sample of 2,509 adults from 4 cities in Mexico. PTSD was assessed according to Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1994) criteria using the Composite International Diagnostic Interview (CIDI; WHO, 1997). Lifetime prevalence of exposure and PTSD were 76% and 11.2%, respectively. Risk for PTSD was highest in Oaxaca (the poorest city), persons of lower socioeconomic status, and women. Conditional risk for PTSD was highest following sexual violence, but nonsexual violence and traumatic bereavement had greater overall impact because of their frequency. Of lifetime cases, 62% became chronic; only 42% received medical or professional care. The research demonstrates the importance of expanding the epidemiologic research base on trauma to include developing countries around the world. 相似文献

Previous work has demonstrated that the graded internal structure of phonetic categories is sensitive to a variety of contextual factors. One such factor is place of articulation: The best exemplars of voiceless stop consonants along auditory bilabial and velar voice onset time (VOT) continua occur over different ranges of VOTs (Volaitis & Miller, 1992). In the present study, we exploited the McGurk effect to examine whether visual information for place of articulation also shifts the best exemplar range for voiceless consonants, following Green and Kuhl's (1989) demonstration of effects of visual place of articulation on the location of voicing boundaries. In Experiment 1, we established that /p/ and /t/ have different best exemplar ranges along auditory bilabial and alveolar VOT continua. We then found, in Experiment 2, a similar shift in the best-exemplar range for /t/ relative to that for /p/ when there was a change in visual place of articulation, with auditory place of articulation held constant. These findings indicate that the perceptual mechanisms that determine internal phonetic category structure are sensitive to visual, as well as to auditory, information. 相似文献

The authors examined how people integrate knowledge of agents and patients of events with the temporal and causal properties of present and past participles to constrain interpretation of isolated participle-noun phrases like arresting cop and arrested crook. Good-agent head nouns were more easily combined with present participles (e.g., arresting cop) than with past participles (e.g., arrested cop), and the reverse was true for good patients. Furthermore, present-participle good-patient phrases (e.g., serving customer) were often interpreted as verb phrases. This research provides further evidence of the interaction between morphosyntactic cues and world knowledge of events in language comprehension. 相似文献

Mood changes after maximal exercise testing in subjects with symptoms of exercise dependence 总被引:1,自引:0,他引:1
Considering exercise has positive and negative reinforcing properties, the mood states of sedentary, nonexercise-dependent and exercise-dependent volunteers were compared after maximal exercise testing. Mood status was evaluated by the Beck Depression Inventory, Trait-State Anxiety Inventory, and Profile of Mood States (POMS). No differences were detected before the test or after it, indicating little possibility of positive reinforcement. However, a significant reduction in the POMS Tension-Anxiety scores was observed in both exerciser groups (greater in the exercise-dependent group) but not in the sedentary group. Only in the exercise-dependent group were significant reductions in Anger and Total Mood Disorders scores observed compared with their pre-exercise scores. These data suggest that exercising has stronger negative reinforcement properties for exercise-dependent volunteers and is a factor which could increase the odds of their becoming dependent on exercise. 相似文献

We evaluated the role of the medial prefrontal cortex (mPFC) in the elaboration of egocentric navigation strategies in a water maze (WM). Lesions of mPFC cell bodies was achieved in 21 rats using bilateral injections of ibotenic acid (IA); 13 control rats were injected with saline. After 17 days, rats had to learn an allocentric (using external cues: 10 lesioned, 7 saline rats) or an egocentric WM (using internal/kinetic cues: 10 lesioned, 6 saline rats) over six trials in a same session. The initial trajectory on the sixth trial was used as an index of the elaboration of a navigation strategy. In the egocentric test, lesioned rats were more rarely located in the target quadrant than control rats. No differences were found between lesioned and control rats in the allocentric test. These results show that lesions of the mPFC impairs the capacity to elaborate an egocentric navigation strategy. 相似文献

Exposure is a highly effective treatment for pathological fear and anxiety, but rarely used in routine care. Issues of practicability and lack of therapists in rural areas are main barriers for the dissemination of exposure. Smartglass devices may enable therapists to guide exposure from their own office via real-time feedback and may thereby increase practicability. The present study explored the technological usability and clinical feasibility of Smartglass-guided exposure in a behavioral approach test in spider-fearful individuals (N = 40).Fearful individuals were asked to start the Smartglass themselves and established a connection to a therapist, who guided the exposure test from afar. Clinical severity of spider fear was assessed via questionnaire. Technological usability was assessed with established measures of usability, user experience, and user acceptance. Exploratory, individual characteristics of exposure were collected (e.g., within-session fear reduction, duration, safety behavior).Overall, fearful individuals (94.9%) and therapists (100%) were able to establish a connection. Usability of Smartglass-guided exposure was evaluated as positive. Within-session fear reduction was large (d = 1.91). Adverse events were minimal. There were, however, some associations between exposure characteristics and usability evaluation (e.g., lower user-friendliness and exposure duration). Two case examples further highlight chances and risks of Smartglass-guided exposure.These findings provide first evidence that Smartglass-guided exposure could be useful in exposure therapy. Smartglass-guided exposure may ultimately help to increase practicability of exposure and increase dissemination, also in rural areas. These findings are promising for future research on the long-term outcome of evidence-based exposure in treatment seeking patients. 相似文献

The misclassification error distance and the adjusted Rand index are two of the most common criteria used to evaluate the performance of clustering algorithms. This paper provides an in-depth comparison of the two criteria, with the aim of better understand exactly what they measure, their properties and their differences. Starting from their population origins, the investigation includes many data analysis examples and the study of particular cases in great detail. An exhaustive simulation study provides insight into the criteria distributions and reveals some previous misconceptions. 相似文献

Carers of patients with borderline personality disorder (BPD) experience high levels of distress. Several studies have been carried out on interventions designed to decrease their burden. However, the evidence from these studies has not been summarized. The objective of this work is to explore the clinical utility of interventions developed for family members of patients with BPD. A systematic review was conducted following the PRISMA guidelines (registration number CRD42018107318), including psychological interventions focused on relatives of patients with BPD. The following databases were used: PsycINFO, PubMed, EBSCOhost, and Web of Science. Two independent researchers reviewed the studies to determine whether the eligibility criteria were met. A total of 2,303 abstracts were identified. After duplicates had been removed, 1,746 studies were screened. Finally, 433 full‐text articles were reviewed, yielding 11 studies that satisfied the inclusion criteria. Results show that these interventions with different clinical formats and settings are effective. The quality of the included studies varies, and the empirical support for these programs is still preliminary. The results help to establish a general framework for interventions specifically developed for family members of patients with BPD, but additional efforts should be made to improve the methodological quality of this field of research and more solidly determine the utility of these interventions. Given the paucity of data so far, this information may open up new lines of research to improve the effectiveness of future programs for carers of patients with BPD and help to reduce their burden. 相似文献
