Accumulating evidence suggests that particular kinds of dysfunctional beliefs contribute to obsessive-compulsive (OC) symptoms. Three domains of beliefs have been identified: (a) perfectionism and intolerance of uncertainty, (b) overimportance of thoughts and the need to control thoughts, and (c) inflated responsibility and overestimation of threat. These beliefs and OC symptoms are both heritable. Although it is widely acknowledged that OC symptoms probably have a complex biopsychosocial etiology, to our knowledge there has been no previous attempt to integrate dysfunctional beliefs and genetic factors into a unified, empirically supported model. The present study was an initial step in that direction. A community sample of monozygotic and dizygotic twins (N = 307 pairs) completed measures of dysfunctional beliefs and OC symptoms. Structural equation modeling was used to compare 3 models: (a) the belief causation model, in which genetic and environmental factors influence beliefs and OC symptoms, and beliefs also influence symptoms; (b) the symptom causation model, which is the same as (a) except that symptoms cause beliefs; and (c) the belief coeffect model, in which beliefs and OC symptoms are the product of common genetic and environmental factors, and beliefs have no causal influence on symptoms. The belief causation model was the best fitting model. Beliefs accounted for a mean of 18% of phenotypic variance in OC symptoms. Genetic and environmental factors, respectively, accounted for an additional 36% and 47% of phenotypic variance. The results suggest that further biopsychosocial investigations may be fruitful for unraveling the etiology of obsessions and compulsions. 相似文献

This study examined whether a virtual avatar could be perceived as a real human by patients with mental disease, especially schizophrenia, as well as whether a virtual avatar could be applied to acquiring patients' behavior characteristics in a short conversation situation. The virtual avatar has been used for various applications which need to communicate with other person or to train or educate by showing humanlike behavior. Recently, many researches have shown that the virtual avatar technology has been enhanced and the avatar could be perceived like real human. A virtual avatar, standing in a virtual room, was designed for this study. Tasks to approach, initiate a talk, and answer to avatar's questions was assigned to the 11 patients with schizophrenia. As behavioral parameters in the virtual environment, the interpersonal distance and the verbal response time were acquired. In addition, the Positive and Negative Syndrome Scale (PANSS) for patients was administered in order to investigate the relationship between patients' symptomatic characteristics and behavior parameters. The interpersonal distance was negatively correlated with the negative syndrome scale, a subscale of PANSS, which is consistent with previous research reporting the relationship between interpersonal distance and a real person's image. The verbal response time, however, was not correlated with any other subscale of PANSS. After analyzing subitems of the negative syndrome of PANSS, two positive correlations were found: one was with blunted affect and the other was with poor rapport. We concluded that the virtual avatar could be perceived as a real human by schizophrenic patients and the avatar could draw the schizophrenic patients' behavior characteristics. 相似文献

Video-capture virtual reality (VR) systems are gaining popularity as intervention tools. To date, these platforms offer visual and audio feedback but do not provide haptic feedback. We contend that adding haptic feedback may enhance the quality of intervention for various theoretical and empirical reasons. This study aims to integrate haptic-tactile feedback into a video capture system (GX VR), which is currently applied for rehabilitation. The proposed multi-modal system can deliver audio-visual as well as vibrotactile feedback. The latter is provided via small vibratory discs attached to the patient's limbs. This paper describes the system, the guidelines of its design, and the ongoing usability study. 相似文献

Schizophrenia is a devastating mental illness and is characterized by hallucinations and delusions as well as social skills deficits. Generally, social skills training designed to help patients develop social skills includes role-playing, but this form of training has typical shortcomings, which are largely due to a trainer's difficulties to project emotion. Virtual reality (VR)-based techniques have the potential to solve these difficulties, because they provide a computer-generated but realistic three-dimensional world and humanlike avatars that can provide emotional stimuli. In this paper, we report on a method of implementing virtual environments (VEs) in order to train people with schizophrenia to develop conversational skills in specific situations, which could overcome the shortcomings of or complement conventional role-playing techniques. The paper reports the efficacy of the proposed approach in a preliminary clinical trial with 10 patients with schizophrenia. 相似文献

Impairment in social skills is one of the few criteria that all individuals diagnosed with schizophrenia must meet. Successful social skills require the coordination of many abilities, including social perception, which involves the decoding and interpretation of social cues from others. In this study, we examined the potential for virtual reality (VR) in social skill training. We attempted to determine if VR can be used to measure social skills and social perception, and to determine which VR parameters are related to schizophrenic symptoms. Some of these results have clear clinical relevance, while other observations need further study. The VR system appears to be useful in assessing the social perception of schizophrenics and normal people, and could be more widely used in the future for social training and in the assessment of social problem-solving abilities, assertiveness skills, and general social skills. 相似文献

The aim of this study was to examine the relationship between parenting and sexual attitudes and behaviors of college students in India. Both physical sexual behaviors and online sexual behaviors were examined. A sub-sample of Indian college students aged 18–25 years (n?=?159; 32% female) recruited online for survey completion were the focus of this study. Two path models were performed to explore how sexual attitudes and behaviors were associated with perceived parental solicitation, trust, and warmth. Maternal and paternal influences were tested in separate models. Mothering was more strongly associated with daughters’ sexual behaviors while fathering was associated with sons. College students with liberal sexual attitudes reported engaging in more physical and online sexual behaviors. As Indian youth experience a more globalizing coming of age than previous generations, they require an extended period of parental support and involvement. Findings in the current study suggest that young adults are receptive to parental influence with warm and trusting parent–child relationships playing a significant role in shaping college students’ sexual behaviors. 相似文献

The aim of this study was to explore the relationship between mental health and the perceived importance of religion and the frequency of prayer among 200 children ages 10–18 years who lived in temporary camps for earthquake survivors in Nepal. The participants were examined using the Child Behavior Checklist (CBCL) 6–18 and were asked about the importance of religion in their lives. In contrast to expectation that high perceived importance of religion and prayer frequency have positive impacts on mental health after earthquakes, the results indicated significantly higher levels of withdrawal/depression. The group that prayed less frequently after the earthquakes had significantly higher scores for somatic symptoms, withdrawal/depression, anxiety/depression, social immaturity, internalising problems, and total CBCL scores. However, the clinical risk group (T score of 65 or higher in the CBCL total score), no significant difference according to the importance of religion showed and frequency of daily prayer. 相似文献

In computer-mediated communication (CMC) systems, the messages that a user types usually persist on the screen for some time, a feature that distinguishes CMC from face-to-face interaction. Persistence may activate psychological self-perception, leading communicators to infer from their persistent messaging how they feel about the subject more so than if messages did not persist. This study applies persistence and self-perception to the relationships between self-disclosure and liking. It identifies which among several disclosure or liking relationships may be most susceptible to self-perception effects. An experiment found that message persistence interacts with a conversational partner’s responses to self-disclosure and intensifies liking toward the partner. Suggestions follow for future research further exploring the mechanisms of persistence, and reconceptualizing self-perception factors in interactive media settings. 相似文献

Background. Empirical evidence involving the processing of social information by patients with obsessive–compulsive disorder (OCD) has been relatively scarce. Our study investigated the perceptual abilities of patients with OCD to recognize human faces and bodies. Method. Fifty‐four drug‐free or drug‐naïve patients with OCD and 42 healthy controls performed discrimination tasks consisting of four types of stimuli: two sets of faces that were manipulated with regard to configuration and features, human bodies, and chairs. The stimuli were presented in upright and upside‐down orientations. Results. Patients with OCD were significantly less accurate in discriminating pairs of bodily postures implying actions. However, we found no significant differences between patient and control groups in the ability to recognize faces and chairs. The inversion effects for bodies and faces were also comparable between the two groups. Conclusions. The current findings suggest that patients with OCD experience difficulty in perceiving static forms of bodily postures, but are able to adequately recognize human faces. Our data indicate a selective deficit in the perception of bodily postures in those with OCD and suggest that this deficit is probably not related to the abnormal configurational processing of social objects. 相似文献

How many dimensions underlie judgments of learning and recall? Evidence from state-trace methodology
The authors used state-trace methodology to investigate whether a single dimension (e.g., strength) is sufficient to account for recall and judgments of learning (JOLs) or whether multiple dimensions (e.g., intrinsic and extrinsic factors) are needed. The authors separately manipulated the independent variables of intrinsic and extrinsic cues, determining their state traces for recall and JOLs. In contrast to the supposition that intrinsic cues have similar effects on both recall and JOLs whereas extrinsic cues affect JOLs less strongly than recall (i.e., 2 dimensions underlying recall and JOLs), the authors found repeated support for the sufficiency of a single dimension for both recall and JOLs (not only immediate JOLs but also delayed JOLs) across a variety of intrinsic and extrinsic cues. 相似文献
