汶川地震9.5年后,对汶川县和都江堰市767名中学生进行调查,考察惩罚敏感性和孤独感在创伤后应激障碍症状和网络成瘾症状之间的多重中介作用及性别差异。结果发现:(1)PTSD症状正向预测网络成瘾症状,并分别通过惩罚敏感性、孤独感的单独中介作用及两者的链式中介作用显著预测网络成瘾症状;(2)女性的PTSD症状显著正向预测网络成瘾症状,并分别通过惩罚敏感性和孤独感间接影响网络成瘾症状;男性的网络成瘾症状仅被PTSD症状正向预测。  相似文献

As shown in our previous paper (‘Regression I. Experimental approaches to regression’, JAP, 65, 2, 345-65), the common mechanism of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the proportion of low-differentiated (older) systems in actualized experience. Experimental data show that regression following disease (chronic tension headache) is followed by adaptation and an increase in system differentiation in that experience domain which contains systems responsible for that adaptation. The results of mathematical modelling support the idea that reversible dedifferentiation can be one of the mechanisms for increasing the effectiveness of adaptation through learning. Reversible dedifferentiation, which is phenomenologically described as regression, is a general mechanism for restructuring the organism-environment interactions in situations where behaviours that were effective in the past become ineffective. Reversible dedifferentiation has evolved as a component of adaptation when new behaviours are formed and large-scale modifications in the existing behaviours are required in the face of changes in the external and/or internal environment. Thus, the authors believe that this article provides evidence for Jung’s view that regression is not only a ‘return’ to past forms of thinking, affects and behaviour, but that regressive processes provide a significant impetus for psychological growth and development.  相似文献

Abstract

By integrating job demands-resources theory with social information processing theory, we examined how and when seeking challenges and seeking resources influence employees’ turnover intention and helping behavior. We propose that seeking challenges and seeking resources increase employees’ psychological capital. We furthermore suggest that the effects of seeking challenges and seeking resources on psychological capital are moderated by job insecurity, such that employees with high job insecurity will gain more psychological capital through seeking challenges and less psychological capital through seeking resources. Results from a multiwave, multisource study using a sample of 245 supervisor-subordinate dyads provided support for our hypotheses. Implications for theory and practice are discussed.  相似文献

G.E.M. Anscombe argued that we should dispense with deontic concepts when doing ethics, if it is psychologically possible to do so. In response, I contend that deontic concepts are constitutive of the common moral experience of guilt. This has two consequences for Anscombe's position. First, seeing that guilt is a deontic emotion, we should recognize that Anscombe's qualification on her thesis applies: psychologically, we need deontology to understand our obligations and hence whether our guilt is warranted. Second, the fact that guilt is a deontic moral emotion debunks Anscombe's claim that deontic concepts are a relic of the Western, religious past: guilt feelings–hence the idea of moral duty as well–can be found in cultures without an ethics of divine command. Modern moral philosophers' interest in oughts and obligations is not an academic hobbyhorse, but a vital concern arising out of a primeval human emotion.  相似文献

Social networking sites (SNSs) enrol new subscribers each day. However, problematic SNS use has undesirable effects on psychological functioning. Therefore, it is important to identify the factors that contribute to the development of problematic SNS use. Very few studies have focused on revealing the underlying mechanisms of problematic SNS use. Although many past studies have examined the relationship between metacognitive beliefs and Internet addiction, the association between metacognitive beliefs and problematic SNS use has not been adequately explored. In this study, we aimed to explore the association between metacognitive beliefs and problematic SNS use among young adults. A total of 308 individuals participated in this study. A socio-demographic data form, the Metacognitions Questionnaire-30 (MCQ-30), and Social Media Addiction Scale (SMAS) were administered. Group comparisons were performed using multivariate analysis of covariance. Pearson's correlational and multiple linear regression analyses were conducted to examine the associations between metacognitive beliefs and problematic SNS use. The SNS addicts scored higher in all of the SMAS assessments. When compared to non-addicts, SNS addicts obtained higher scores on all the subtests of the SMAS and MCQ-30 except cognitive self-consciousness. The negative beliefs about the uncontrollability and danger of worry, cognitive confidence, and need for control thoughts were associated with SMAS mood modification, relapse and conflict subdimensions. Our findings revealed that dysfunctional metacognitive beliefs are related to problematic SNS use among young adults. These findings indicate that mental health workers should consider the modification of metacognitive beliefs in the treatment of problematic SNS use.  相似文献

Our objective was to examine the differential effects of antenatal breastfeeding intention (BI) and breastfeeding practice (BP) on maternal postnatal responsiveness. We conducted a secondary analysis of longitudinal data from a subsample of 962 mother–infant dyads from a U.K.-based birth cohort study the Avon Longitudinal Study of Parents and Children. Exposures were BI and BPs measured at 32 weeks of gestation and 18 months’ postpartum. The outcome was maternal responsiveness assessed at 12 months’ postpartum. We used logistic regression analyses unadjusted and adjusted for confounders. Intention to breastfeed was associated with increased odds of postnatal maternal responsiveness independent of BP, adjusted odds ratio (OR) = 2.34, 95% CI [1.42, 3.86]. There was no evidence that BP was an independent predictor of maternal responsiveness, OR = 0.93, 95% CI [0.55, 1.57]. Life-course epidemiology analyses demonstrated that maternal responsiveness is most positive when both BI and BP are present. This is the first population-based study to provide evidence that BI during pregnancy is more strongly associated with maternal postnatal responsiveness than is BP. Further research is needed to understand the determinants of BI in pregnancy and its relationships with maternal responsiveness.  相似文献

外观创新在市场竞争中的地位越来越突出,然而因此而导致的成败案例都很普遍。如何进行外观创新更受消费者欢迎,其内在机制是什么,我们却知之甚少。基于独特性需求理论、风险感知理论及自我建构理论,本文探讨了自我建构与外观新颖性对消费者购买意愿的交互作用、影响机制以及边界条件。通过3个实验,发现对于独立型自我建构的消费者而言,高外观新颖性能引发独特性需求从而提高购买意愿,而对于相依型自我建构而言,低外观新颖性则通过降低社会风险感知从而提高购买意愿;同时,本文也确定了产品类型对该机制的调节作用,具体来讲,对于实用品,所有消费者都对低外观新颖性产品具有更强的购买意愿,而对于享乐品,所有消费者都对高外观新颖性产品具有更强的购买意愿。  相似文献

New technologies based on artificial agents promise to change the next generation of autonomous systems and therefore our interaction with them. Systems based on artificial agents such as self-driving cars and social robots are examples of this technology that is seeking to improve the quality of people’s life. Cognitive architectures aim to create some of the most challenging artificial agents commonly known as bio-inspired cognitive agents. This type of artificial agent seeks to embody human-like intelligence in order to operate and solve problems in the real world as humans do. Moreover, some cognitive architectures such as Soar, LIDA, ACT-R, and iCub try to be fundamental architectures for the Artificial General Intelligence model of human cognition. Therefore, researchers in the machine ethics field face ethical questions related to what mechanisms an artificial agent must have for making moral decisions in order to ensure that their actions are always ethically right. This paper aims to identify some challenges that researchers need to solve in order to create ethical cognitive architectures. These cognitive architectures are characterized by the capacity to endow artificial agents with appropriate mechanisms to exhibit explicit ethical behavior. Additionally, we offer some reasons to develop ethical cognitive architectures. We hope that this study can be useful to guide future research on ethical cognitive architectures.  相似文献

人们喜欢关注道德事件并表达自己的立场。以往研究发现回忆自己(而非他人)的道德行为能影响个体的道德自我知觉和道德行为。本研究关注参与道德评价是否会对个体的道德自我和道德行为产生影响。2个研究共同发现:(1)存在道德“沾光”效应:评价支持他人的道德事件,或反对他人的不道德事件,能提升个体的道德自我知觉;(2)道德评价通过提升道德自我知觉,进一步增加个体的道德行为。  相似文献

采用道德困境判断的CNI(consequence, norm, inaction)模型,通过两个实验考察权力感对道德困境判断的影响。实验1探讨个人权力感对道德困境判断的影响,结果显示高个人权力感显著增加被试对规则的敏感,促使个体做出道义论的道德判断。实验2考察回忆任务启动的权力感对道德困境判断的影响,发现相对于低权力感启动的被试,高权力感启动的被试在进行判断时更关注行为的结果,对规则更不敏感,这说明启动的权力感促进功利主义的道德判断,抑制道义论的道德判断。结果表明,不同类型的权力感对道德困境判断的影响存在差异。  相似文献
