本文以在校大学生为被试,考察社会比较的一个重要领域—学业竞争中的比较偏差。通过操纵竞争双方的实力(强VS.弱)以及竞争对手的信息清晰度(清晰VS.模糊)来考察不同的任务类型与信息清晰度对竞争中认知偏差的影响,以及探讨认知偏差对决策者决策意图的影响。结果发现,在社会比较中,面对不同类型的问题,会出现不同的认知偏差;竞争双方信息清晰时优于常人效应会减弱;认知偏差会影响个体的决策意图和决策行为。  相似文献

Harvey's cognitive model of insomnia (2002a) proposes that sleep-related safety behaviors play a central role in the maintenance of insomnia because such maladaptive coping strategies are thought to reinforce threat-based appraisals of the likelihood and consequences of poor sleep. Research to date has assessed the frequency of safety behavior use in those with insomnia only; however, in addition to the frequency of occurrence, the function of safety behaviors (i.e., a belief that they will prevent a feared outcome from occurring), may be an important consideration. The purpose of this study was to examine sleep-related safety behaviors based on an expanded theoretical understanding of such behaviors across psychological disorders; that is, by examining both their frequency and perceived utility. Undergraduate students (N = 376) completed an online survey about their sleep, mood, and use of sleep-related safety behaviors. Insomnia severity was associated with a greater perceived need to use safety behaviors (i.e., utility) but not with frequency of safety behavior use. Higher perceived utility of safety behaviors was also associated with unhelpful beliefs about sleep, fear and avoidance of fatigue, and both general and sleep-specific helplessness. These results suggest that these behaviors and the associated underlying maladaptive beliefs may be important targets in cognitive behavioral therapy for insomnia. The current study extends the existing literature and refines the concept of safety behaviors in insomnia to include both the function and frequency of these behaviors.  相似文献

Emotional eating has been identified as a factor that promotes the development and maintenance of obesity and hinders its treatment. This study investigated the relationship between unsatisfied basic needs and emotional eating, including the mediating factors of self‐esteem and coping strategies. The results from a survey of 136 obese individuals indicated support for a significant relationship between basic need satisfaction and emotional eating, with a mediating effect of negative coping strategies. These findings extend previous research and provide guidance on how to help individuals who engage in emotional eating by focusing on developing more adaptive coping strategies.  相似文献

We examined the therapeutic efficacy of a culturally adapted form of CBT (CA-CBT) for PTSD as compared to applied muscle relaxation (AMR) for female Latino patients with treatment-resistant PTSD. Participants were randomized to receive either CA-CBT (n = 12) or AMR (n = 12), and were assessed before treatment, after treatment, and at a 12-week follow-up. The treatments were manualized and delivered in the form of group therapy across 14 weekly sessions. Assessments included a measure of PTSD, anxiety, culturally relevant idioms of distress (nervios and ataque de nervios), and emotion regulation ability. Patients receiving CA-CBT improved significantly more than in the AMR condition. Effect size estimates showed very large reductions in PTSD symptoms from pretreatment to posttreatment in the CA-CBT group (Cohen’s d = 2.6) but only modest improvements in the AMR group (0.8). These results suggest that CA-CBT can be beneficial for previously treatment-resistant PTSD in Latino women.  相似文献

Background

Emotion regulation deficits have been consistently linked to psychopathology in cross-sectional studies. However, the direction of the relationship between emotion regulation and psychopathology is unclear. This study examined the longitudinal and reciprocal relationships between emotion regulation deficits and psychopathology in adolescents.

Methods

Emotion dysregulation and symptomatology (depression, anxiety, aggressive behavior, and eating pathology) were assessed in a large, diverse sample of adolescents (N = 1065) at two time points separated by seven months. Structural equation modeling was used to examine the longitudinal and reciprocal relationships between emotion dysregulation and symptoms of psychopathology.

Results

The three distinct emotion processes examined here (emotional understanding, dysregulated expression of sadness and anger, and ruminative responses to distress) formed a unitary latent emotion dysregulation factor. Emotion dysregulation predicted increases in anxiety symptoms, aggressive behavior, and eating pathology after controlling for baseline symptoms but did not predict depressive symptoms. In contrast, none of the four types of psychopathology predicted increases in emotion dysregulation after controlling for baseline emotion dysregulation.

Conclusions

Emotion dysregulation appears to be an important transdiagnostic factor that increases risk for a wide range of psychopathology outcomes in adolescence. These results suggest targets for preventive interventions during this developmental period of risk.  相似文献

The catastrophic Wenchuan earthquake measuring 8.0 on the Richter scale occurred on May 12, 2008 in the West of the Sichuan basin in China and caused severe damage. A project was undertaken to examine the cognitive and psychological effects one year after the disaster among 2080 individuals in the local area. We evaluated the influence of gender, age, education level, and ethnic group on five aspects: work satisfaction, living satisfaction, health self-perception, psychological pressure, and psychological recovery. Male subjects had a better performance in all five aspects, which indicated that women were more affected. Subjects of different ethnic groups showed significantly different attitudes with respect to psychological pressure and psychological recovery. Significant differences for all the five aspects were also found in education level and age. The results showed that older people and those with a lower education level probably had more psychological problems. There were significant correlations between work satisfaction and living satisfaction, living satisfaction and health self-perception, living satisfaction and psychological recovery, and psychological pressure and psychosocial recovery. Living satisfaction and education level were significant predictors of psychological pressure. For psychological recovery, significant predictors were living satisfaction, age, work satisfaction, education level, and gender. The study findings indicated that government programs should provide more support for females, older people, those with a lower education level, and those in lower living conditions. Attention should be given not only to the psychological effects on each victim, but also to related issues such as work and living conditions to promote psychological wellbeing. Limitations of this study are addressed.  相似文献

The Face-to-Face Still-Face paradigm (FFSF) has been used to investigate how infants react to stressful events. However, there is little developmental data on the FFSF effect, and whether it connects to a specific relationship (e.g., to a mother versus a stranger). This prospective longitudinal study aims to evaluate developmental changes in infant reaction to the FFSF presented by the mother or a stranger at 2, 4, 6, and 8 months of age (n = 39). Results show that infant negativity was expressed less in relation to a stranger, the identity effect. Results further suggest that from 6 to 8 months of age, stranger induced protest flattens out; whereas mother induced protest decreases. The results are discussed in relation to different theories regarding infant responsiveness.  相似文献

Recent structural and functional imaging studies have provided evidence for continued development of brain regions involved in social cognition during adolescence. In this paper, we review this rapidly expanding area of neuroscience and describe models of neurocognitive development that have emerged recently. One implication of these models is that neural development underlies commonly observed adolescent phenomena such as susceptibility to peer influence and sensitivity to peer rejection. Experimental behavioural evidence of rejection sensitivity in adolescence is currently sparse. Here, we describe a study that directly compared the affective consequences of an experimental ostracism manipulation (Cyberball) in female adolescents and adults. The ostracism condition led to significantly greater affective consequences in the adolescents compared with adults. This suggests that the ability to regulate distress resulting from ostracism continues to develop between adolescence and adulthood. The results are discussed in the context of models of neurocognitive development.  相似文献
