Previous studies have shown that the prosocial behavior of individuals may be promoted or inhibited by the presence of others. This study hypothesizes that prosocial behavior relates to the relationships among present individuals, beyond their number. This study examines whether there is a significant difference in an individual's prosocial behavior in the presence of different types of others (strangers or friends) and whether this effect is mediated by the perception of face. Two studies that used different methods of data collection were conducted. It was found that the presence of friends promotes prosocial behavior more than does the presence of strangers. In addition, perceived face plays a mediating role between the presence of different types of people and prosocial behavior. 相似文献

Emotionally focused couple therapy (EFT) is an empirically validated attachment based approach to couple therapy. From an EFT perspective, sexual functioning is viewed within the context of an attachment bond, but sexual satisfaction in EFT has not been empirically tested. We examined self-reported sexual satisfaction across 24?months in a sample of 32 couples who received an average of 21 EFT sessions. We found that sexual satisfaction increased across six time points from pre to post therapy and across follow-up (6, 12, 18, and 24?months), and that decreases in attachment avoidance from pre to post therapy predicted increases in sexual satisfaction across time. These findings provide evidence that EFT may help couples improve their sexual satisfaction by reducing attachment avoidance in therapy. 相似文献

Existing antivirus programs detect malicious code based on fixed signatures; therefore, they have limitations in detecting metamorphic malicious code that lacks signature information or possesses circumventing code inserted into it. Research on the methods for detecting this type of metamorphic malicious code primarily focuses on techniques that can detect code based on behavioral similarity to known malicious code. However, these techniques measure the degree of similarity with existing malicious code using API function call patterns. Therefore, they have certain disadvantages, such as low accuracy and large detection times. In this paper, we propose a method which can overcome the limitations of existing methods by using the FP-Growth algorithm, a data mining technique, and the Markov Logic Networks algorithm, a probabilistic inference method. To perform a comparative evaluation of the proposed method's malicious code behavior detection, we performed inference experiments using malicious code with an inserted code for random malicious behavior. We performed experiments to select optimal weights for each inference rule to improve our malicious code behavior inferences’ accuracy. The results of experiments, in which we performed a comparative evaluation with the General Bayesian Network, showed that the proposed method had an 8% higher classification performance. 相似文献

成瘾行为给个体和社会带来了严重的危害。对成瘾人群时间洞察力的研究成为探讨成瘾行为产生和发展的一个新的视角。过去消极、现在享乐和现在宿命时间洞察力取向的个体更可能出现成瘾行为, 而未来时间洞察力取向则是成瘾行为的一个保护性因素, 它不仅可以减少成瘾行为的发生, 也有利于成瘾行为的康复。从自我调节, 冲动性决策等行为机制和前额叶的神经机制方面可以帮助我们深入理解时间洞察力对成瘾行为的影响。未来研究可以进一步探讨不同成瘾行为者时间洞察力的一致性与特异性; 采用纵向研究方法探讨成瘾者时间洞察力的动态变化过程; 对成瘾者的洞察力进行干预, 增加成瘾者的未来时间洞察力, 减少其过去消极和现在时间洞察力取向来帮助成瘾者实现时间洞察力的平衡, 从而提高其戒断效果。 相似文献

自我客体化的女性会内化他人的评价,把自己当做物品一样来定义和评价自我,并习惯性地对自己的身体以及外貌进行监测,从而导致身体羞耻、焦虑、“心流”体验的减少及身体内部感知的迟钝,并进一步造成更多的不良后果。以往的研究多关注于自我客体化在女性心理健康上造成的影响,很少有研究关注于自我客体户对认知表现的影响。本文梳理了自我客体户与认知表现的相关研究,以及自我客体户对认知表现可能的作用机制。未来研究需要从多方面来丰富自我客体化的操纵方式,通过实验的方式来检验自我客体化对认知表现的作用机制,以及考察不同的认知表现,并关注自我客体化对认知表现的累积效应。 相似文献

摘 要 为探讨神经质、青少年情绪化饮食、体验回避及自尊之间的关系,选取1000名青少年为被试,采用简式大五人格问卷、荷兰饮食行为问卷、接纳行动量表及自尊量表进行测试。结果表明:(1)神经质对青少年情绪化饮食有显著的正向影响,并间接地通过体验回避对青少年情绪化饮食产生作用;(2)自尊在体验回避对青少年情绪化饮食的影响中起显著的调节作用,具体而言,在低自尊水平下,体验回避能显著地正向预测青少年情绪化饮食,而在高自尊水平下,体验回避对青少年情绪化饮食的预测作用不显著。 相似文献

亲组织不道德行为是近年来组织行为学界广泛关注的研究议题。但是, 关于亲组织不道德行为的概念内涵, 目前还存在一定模糊性。基于动机视角, 从亲组织不道德行为的定义、特征、动机、类型等方面, 对亲组织不道德行为的概念模糊性进行细致解构与深入剖析, 形成相对系统的亲组织不道德行为概念内涵; 并据此概念内涵背后的动机逻辑, 对现有的亲组织不道德行为影响因素进行分类梳理, 阐释其对亲组织不道德行为的影响机制; 最后, 从细分类型、测量工具、研究视角、影响因素、抑制机制、影响效应与本土化等方面为后续研究提供针对性的建议。 相似文献

Transdiagnostic cognitive behavioral interventions target different cognitive processes to promote mental health, including cognitive fusion and cognitive reappraisal. Determining the relative impact of cognitive fusion and reappraisal on a range of student mental health concerns could help interventions target psychopathological cognitive processes more effectively. Therefore, this study examined the longitudinal impact of cognitive fusion and reappraisal on mental health and functioning outcomes. A series of hierarchical regression models tested the effects of cognitive fusion and reappraisal in a sample of college students (n = 339). When controlling for reappraisal and baseline symptoms, fusion predicted distress, depression, generalized anxiety, social anxiety, hostility, academic distress, and student role problems 1 month later. Reappraisal predicted only student role problems longitudinally when controlling for fusion. These results suggest that cognitive fusion is a stronger predictor than reappraisal for a range of student mental health concerns and may be a particularly important target for improving student mental health. 相似文献

The purpose of the study was to evaluate the factor structure and the reliability of the Prosocial Behavior Scale (PBS). To our knowledge, no factorial validity of the multifactorial structure of PBS has been published to date. The psychometric characteristics of the PBS were examined in several samples of French adolescents (aged 11–19, N1 = 1141, N2 = 1071, and N3 = 1640) using Confirmatory factor analyses (CFA). The original four-factor structure was not confirmed due to lack of discriminant validity. CFA led us to retain a two-factor solution with a good fit and a satisfactory reliability. Furthermore, the results support the convergent validity of the PBS: helping and caring dimensions were positively correlated with empathy. In addition, partial measurement invariance across gender and grade was attested. In conclusion, the results indicate that the French version of the PBS is a useful instrument for the assessment of prosocial behaviors in adolescence. 相似文献
