This study examined the relationship between emotional intelligence (EI), assessed with an ability test, and interpersonal decision-making using the Prisoner’s Dilemma Game (PDG). Previous research found that individuals who self-report high EI tend to cooperate more than others in the Prisoner’s Dilemma. We relativize these findings by showing that individuals scoring high on an ability measure of EI choose effective strategies to deal with three different PDG conditions during real interactions. This suggests that emotionally intelligent individuals are not rigidly predisposed to cooperate regardless of others’ behavior. Instead, EI is associated with the capacity to respond flexibly to others’ strategies and to the interaction context in order to maximize long-term gains – even when this means competing rather than cooperating.  相似文献

本篇综述总结了帕金森病的诊断、鉴别诊断和病程监测的各领域的生物学标记物的研究进展。其中重点介绍了神经影像学和生物化学领域的生物学标记物,也是当前研究较为成熟的两大领域。神经影像学标记物以多巴胺能影像及非多巴胺能影像为代表,生物化学标记物为包括a一突触核蛋白在内的多种蛋白和激素,两者的结合能够有效提高疾病诊断的特异性和灵敏性。同时文章还介绍了当前研究的热点——帕金森病的前驱诊断手段,即在疾病典型的运动症状和非运动症状出现前便可预测帕金森病的诊断手段。  相似文献

炎症性肠病(IBD)病程迁延反复,影响患者生活质量,耗费卫生资源。虽然传统药物如5-氨基水杨酸、糖皮质激素、免疫抑制剂等仍是目前治疗主流,但是大量有关发病机制的研究以及循证医学的发展对IBD的治疗产生了积极的推进作用。IBD的治疗正步入免疫调节的生物学时代,多种新型生物制剂的出现为IBD的治疗提供了新的策略和选择。现就目前IBD药物治疗现状以及最新进展进行综述,以期对临床IBD治疗提供参考。  相似文献

探讨Zuckerkandl结节(ZT)在甲状腺手术中对上甲状旁腺的定位与保护作用.对我院2011年10月至2013年1月在我院行甲状腺手术患者351例进行回顾分析,结果显示,ZT在左侧叶甲状腺的发生率为89.0%(268/301),右侧叶中的发生率为87.3%(254/291),共计5例患者出现术后甲状旁腺功能一过性下降,未有永久性甲状旁腺功能损失患者出现.ZT为甲状腺手术中探查上甲状旁腺提供了新的途径与解剖标志,值得引起甲状腺外科医生的关注.  相似文献

This study extends prior research that identified client-derived variables believed to contribute to therapeutic alliance development. Forty-two clients participated in a three-round-modified Delphi poll in which the subjective importance of 74 client-derived, common alliance formation variables was rated using a six-point scale. Participants consensually identified 23 variables as highly important, five as moderately important and three as low in importance to the formation of a strong alliance. Variables related to validation and asking about parts of the client’s life other than the presenting concern were considered as most important by at least one-third of the sample. Limitations of the study are presented and implications for theory, measurement, practice and future research are briefly discussed.  相似文献

This paper sheds new light on the subtle relation between probability and logic by (i) providing a logical development of Bruno de Finetti's conception of events and (ii) suggesting that the subjective nature of de Finetti's interpretation of probability emerges in a clearer form against such a logical background. By making explicit the epistemic structure which underlies what we call Choice-based probability we show that whilst all rational degrees of belief must be probabilities, the converse doesn't hold: some probability values don't represent decision-relevant quantifications of uncertainty.  相似文献

Parenting has been found to act as a mediator of the relation between parents' depressive symptoms and children's adjustment. The present study replicated this result, and also found specific effects of gender for both parents and children. A total of 319 parents provided reports of their depressive symptoms (BDI) and two parenting styles (APQ; inconsistent discipline and positive parenting) as well as of their elementary schoolchildren's adjustment (VBV-EL; oppositional-defiant behaviour, hyperactivity, internalizing, social-emotional competence). The first and second measurement occasions were six months apart. Bivariate correlations showed the expected pattern of positive associations between parental depression, child maladjustment and problematic parenting. However, the results differed for mothers and fathers, and the mediation was moderated by the children's gender. Inconsistent discipline was a mediator for both fathers and mothers. The path from fathers' depression was additionally negatively mediated by positive parenting. Boys were more vulnerable than girls.  相似文献

To investigate everyday memory, more and more studies rely on virtual‐reality applications to bridge the gap between in situ approaches and laboratory settings. In this vein, the present study was designed to assess everyday‐like memory from the virtual reality‐based Human Object Memory for Everyday Scenes (HOMES) test (Sauzéon et al., 2012 , Exp. Psychol., 59, 99) in ageing and in Alzheimer's disease (AD). Two aims motivated this study: the first was to assess multiple processes of episodic memory (EM) functioning embedded within contexts closely related to real life in ageing and AD using the multi‐trial free‐recall paradigm, and the second aim was to evaluate the mediating effects of executive functioning (EF), EM, and subjective memory complaints (SMCs) on age differences in the HOMES measures and in AD. To this end, the HOMES test and neurocognitive tests of EF and EM were administered to 23 younger adults, 23 older adults, and 16 patients with AD. The results were: firstly, compared to young adults, elderly adults presented only free‐recall decline that almost disappeared in recognition condition whereas AD patients exhibited a poor clustering, learning, and recognition performance, and also a high amount of false recognition; secondly, age differences as well as AD related deficits on the HOMES test were mediated by both memory and EF measure while those observed on false memory indices were only mediated by EM measure; thirdly, the HOMES indices are related to SMCs even when episodic or EF measures are controlled. Overall, the results supported the fact that the VR‐based memory test is an appropriate device to capture age‐related differences as well as the AD effect with respect to both in situ and laboratory settings.  相似文献

The idea of functional differentiation between vision-for-action and vision-for-perception has been supported by evidence from different domains. According to this account, perception is based on consciously accessible, relative representations, whereas vision-for-action is performed in an analytic, automatic manner. Support for this idea comes from studies that showed that unlike perception, grasping movements are refractory to illusions and to Weber’s law. Yet, interactions between the systems may occur when an action is performed in a less automated fashion. To test this idea, we asked participants to monitor their fingers apertures in flight and to halt their movement for a short duration when they felt that their aperture reached a maximum amount. The results showed that movements in the monitored condition were biased by the Ponzo illusion and showed atypical adherence to Weber's law. These results show that action and perception are more likely to interact when movements are performed in a controlled manner.  相似文献
