The association of environmental,individual factors,and dopamine pathway gene variation with smoking cessation

This study aimed to examine whether dopamine (DA) pathway gene variation were associated with smoking cessation, and compare the relative importance of infulence factors on smoking cessation. Participants were recruited from 17 villages of Shandong Province, China. Twenty-five single nucleotide polymorphisms in 8 DA pathway genes were genotyped. Weighted gene score of each gene was used to analyze the whole gene effect. Logistic regression was used to calculate odds ratios (OR) of the total gene score for smoking cessation. Dominance analysis was employed to compare the relative importance of individual, heaviness of smoking, psychological and genetic factors on smoking cessation. 415 successful spontaneous smoking quitters served as the cases, and 404 unsuccessful quitters served as the controls. A significant negative association of total DA pathway gene score and smoking cessation was observed (p < 0.001, OR: 0.25, 95% CI 0.16–0.38). Dominance analysis showed that the most important predictor for smoking cessation was heaviness of smoking score (42%), following by individual (40%), genetic (10%) and psychological score (8%). In conclusion, although the DA pathway gene variation was significantly associated with successful smoking cessation, heaviness of smoking and individual factors had bigger effect than genetic factors on smoking cessation.     

Association of financial and health literacy with cognitive health in old age

We tested the hypothesis that higher financial and health literacy is associated with better cognitive health in 755 older persons who completed a literacy measure (M = 67.9, SD = 14.5) and then had annual clinical evaluations for a mean of 3.4 years. In proportional hazards models, higher literacy was associated with decreased risk of developing incident Alzheimer’s disease (n = 68) and results were similar for financial and health literacy subscales and after adjustment for potential confounders. In mixed-effects models, higher literacy was related to higher baseline level of cognition and reduced cognitive decline in multiple domains. Among the 602 persons without any cognitive impairment at baseline, higher literacy was associated with a reduced rate of cognitive decline and risk of developing incident mild cognitive impairment (n = 142). The results suggest that higher levels of financial and health literacy are associated with maintenance of cognitive health in old age.     

Orientations to Happiness and Subjective Well-Being in Chinese Adolescents: The Roles of Prosocial Behavior and Internet Addictive Behavior

Researchers have studied individual’s pursuit of well-being through two perspectives: the eudaimonic perspective and the hedonic perspective. Peterson and his colleagues (2005) introduced their Orientations to Happiness scale, a self-report measure assessing individual’s pursuit of well-being that corresponds to these two perspectives. Specifically, the Life of Meaning subscale is the index of the eudaimonic pursuit; the Life of Pleasure subscale is the index of the hedonic pursuit. Previous research has demonstrated that orientations to happiness are positively associated with individual’s subjective well-being, whereas little research has addressed the mechanisms underlying the associations. Based on goal theory of happiness, the present study investigated how orientations to happiness were associated with subjective well-being by examining the indirect effects of the prosocial behavior and Internet addictive behavior in a sample of Chinese adolescents aged between 13 and 18 (N = 2082). The results showed that: (1) both life of meaning and life of pleasure were positively associated with adolescents’ subjective well-being; (2) prosocial behavior partially mediated the positive association between life of meaning and subjective well-being; and (3) prosocial behavior also partially mediated the positive association between life of pleasure and subjective well-being, whereas Internet addictive behavior undermined the positive association here. The findings shed light on the underlying mechanisms between orientations to happiness and subjective well-being.     

句法加工中的预测现象及实验证据

句法加工是读者通过整合输入的言语信息来理解句子的过程。句法加工的存在,使得读者能够提前预测文本的信息,提高阅读效率。由于阅读离不开信息整合,研究者提出两类不同的句法理论:句法预测的模块局域性理论和句法预测的互动分析性观点。这两类理论的争论点在于句法加工是单独模块化的自上而下加工,还是自下而上-自上而下的互动分析加工过程。其区别表现为句法预测的作用——前者认为句法预测对句子加工有抑制作用,后者认为句法预测对句子加工起促进作用。来自眼动、ERP等研究的数据佐证了句法预测的存在。未来研究应围绕其差异进行深入探讨,以揭示句法加工的实质。     

自尊的认知神经机制

自尊是个体对自己总体的情感性评价。自尊有助于促进个体的心理健康,帮助个体应对威胁,具有重要的适应价值。近年来随着社会认知神经科学的兴起,关于自尊的认知神经机制的研究日益增多,主要涉及三个方面:1)自尊与大脑的结构(如海马体积、前扣带回等区域的灰质体积)和功能(静息态下的默认网络活动以及脑区之间的功能联结性)存在一定的关联;2)自尊调节大脑对威胁的反应,与高自尊个体相比,低自尊个体面对威胁时产生更强的防御性反应,自尊通过影响个体面对威胁时的大脑活动帮助个体更好地应对威胁;3)自我评价过程涉及大脑前额叶、眶额叶、扣带回等多个脑区,自尊调节个体在自我评价过程中的大脑活动。总之,自尊作为个体重要的人格特质,与大脑的结构、功能以及活动状态等都具有一定的关系;这些发现在一定程度上揭示了自尊的神经机制,加深了对自尊及其功能的理解。     

自我不确定感:内涵、结构和理论

自我不确定感是个体在遇到认知、情感以及行为间的不一致或冲突,对重要的心理品质产生困惑和怀疑时体验到的一致性和连续性缺乏的状态。文章对自我不确定感的概念进行了梳理,然后提出了概念构想模型,认为其结构应包含认知、情绪和动机成分,再后则以自我不确定感的管理策略为线索对相关理论和模型进行了初步整合。未来研究需在明确界定自我不确定感的基础上开展跨文化比较,从多角度检验自我不确定感管理策略的效果,深入探讨自我不确定感的发生和作用机制,探索如何变自我不确定感的被动防御为主动预防与管理。     

不公平感及相关决策的认知神经机制

公平是人类社会生活的基本规范之一,不公平感及其相关决策则是研究者们关注的重要课题。长期以来,该领域的研究一般采用最后通牒博弈或其变式展开。大量脑成像研究探查了关于不公平感及相关决策的认知神经机制,尤其集中探讨了最后通牒博弈的回应者对不公平提议进行反应的脑区及其对应功能。经常得到关注的脑区包括了前脑岛、前扣带皮层、背外侧前额叶、内侧前额叶、杏仁核和颞顶交界等。对特殊人群的不公平感及相关决策进行研究可以帮助检验或澄清上述重要脑区及脑网络在不公平感及相关决策中扮演的角色,同时也阐释特殊人群的社会认知功能的特点。近年来,相当数量的研究关注了不同情境因素(包括分配方案相关因素和社会情境相关因素)调制不公平感及相关决策的过程,并讨论其背后的认知神经机制。未来的研究更应利用多模态数据分析方法,同时结合基因和激素层面的研究,以期深入对不公平感及相关决策的心理和生理机制的理解。     

On recognition and self: a discussion based on Nyāya,Mīmāṃsā and Buddhism

The phenomenon of recognition is a point of contention in the debate between the orthodox Hindus and Buddhists on whether the self (ātman) exists. The Hindus, including Naiyāyikas and Mīmā?sakas, argue that recognition evidences the existence of the self, while Buddhist philosopher ?āntarak?ita maintains that there is no self and recognition should be explained in another way. This article examined two disputes, focusing on the two subsidiary aspects of a recognition: memory and self-recognition. For Hindus, it is the existence of the self that makes memory and self-recognition possible. For Buddhists, it is due to the phenomena of memories and self-recognitions that people postulate the existence of the self. I argue that Buddhist explanation of memory is more acceptable, while their debates on self-recognition should be considered as a tie.     

家庭社会经济地位与父母教养方式对儿童青少年公正世界信念的影响

以全国24013名10~15岁儿童青少年为对象,探讨家庭社会经济地位与父母教养方式对公正世界信念的影响。结果发现：（1）家庭社会经济地位能够正向预测一般公正世界信念与个人公正世界信念;（2）权威型教养方式能够正向预测一般公正世界信念与个人公正世界信念,独裁型与纵容型教养方式能够负向预测一般公正世界信念与个人公正世界信念;（3）家庭社会经济地位与父母教养方式的交互作用对公正世界信念的影响显著,其中,权威型教养方式对高家庭社会经济地位比对低家庭社会经济地位儿童青少年公正世界信念的促进作用更大,独裁型与纵容型教养方式对低家庭社会经济地位比对高家庭社会经济地位儿童青少年公正世界信念的削弱作用更大。
