The Mystery of Chinese People’s Happiness

The great improvement in economic wealth and social welfare over the decade doesn’t promote the Chinese people’s happiness. We construct a theoretical framework which covers economic wealth, social welfare, individual functional capability to explore the impact factors and determinants of the Chinese people’s happiness. Based on a national wide questionnaire survey in China, we test and modify the framework by the method of structural equation model. The empirical findings indicate that there are direct and indirect effects on the formation of happiness. For the direct effect, both the increasing of economic wealth and social welfare improves the national happiness, while the individual functional capability reduces it. For the indirect effect, the individual functional capability also reduces happiness by negatively affecting economic wealth and social welfare. The negative effect that played by individual functional capability overwhelms the positive effect played by economic wealth and social welfare. This causes the Chinese people’s happiness goes down while the economic wealth and social welfare are improving. Finally, we conclude that the Chinese people’s happiness is more about individual functional capability rather than social welfare or economic wealth.     

Understanding the Association Between Spirituality,Religiosity, and Feelings of Happiness and Sadness Among HIV-Positive Indian Adults: Examining Stress-Related Growth as a Mediator

This study examined the role of stress-related growth as a mediator of the associations between spirituality, religiosity, and feelings of happiness and sadness in a sample of 178 HIV-positive Indian adults. Results indicated that spirituality, but not religiosity, was associated with feelings of happiness and sadness. Subsequent mediation analyses indicated that stress-related growth fully mediated the relationships involving spirituality and feelings of happiness and sadness. Overall, our findings point to the importance of facilitating greater spiritual development among HIV-positive Indians, as well as promoting strategies that help them develop and apply stress-related growth coping methods in their lives.     

农村留守儿童焦虑情绪的异质性:基于潜在剖面分析

采用中学生心理健康诊断量表（MHT）对湖南省1292名留守儿童的焦虑情绪进行施测,并用潜在剖面分析方法探究留守儿童的焦虑情绪问题是否存在异质性,以及留守儿童相关的人口学因素对焦虑情绪异质性的作用机制。结果发现,留守儿童的焦虑情绪存在明显的异质性,可以分为三种潜在类别：“严重焦虑情绪型”、“中等程度焦虑情绪型”和“低焦虑情绪型”;留守男生、小学五年级、高中二年级、留守时间越长、留守初始年龄越小的留守儿童更容易焦虑情绪严重;无论是父亲外出、母亲外出还是双亲外出对留守儿童的焦虑情绪严重性的影响是一致的。由此,应根据留守儿童的性别、年级、留守时长和留守的初始年龄等情况特点,开展针对性的预防和干预措施,缓解留守儿童焦虑。     

教师支持与心理素质对中学生学业成绩的影响

采用学生感知教师支持行为问卷和中学生心理素质问卷,对西南地区两所中学7~12年级的824名在校中学生进行调查研究,探讨教师整体支持和不同类型支持与中学生学业成绩的关系及心理素质在其中的中介作用。结果发现：（1）教师整体支持与中学生心理素质、学业成绩间存在显著正相关;教师情感支持与中学生心理素质、学业成绩间存在显著正相关,教师学习支持、能力支持与中学生心理素质存在显著正相关,但与学业成绩相关均不显著;（2）控制性别和年龄后,心理素质在教师整体支持与学业成绩的关系中起完全中介作用;心理素质在教师情感支持与学业成绩关系中起部分中介作用,在教师学习支持与学业成绩、教师能力支持与学业成绩关系中均起完全中介作用。     

Nonlinear Predictive Models for Multiple Mediation Analysis: With an Application to Explore Ethnic Disparities in Anxiety and Depression Among Cancer Survivors

Mediation analysis allows the examination of effects of a third variable (mediator/confounder) in the causal pathway between an exposure and an outcome. The general multiple mediation analysis method (MMA), proposed by Yu et al., improves traditional methods (e.g., estimation of natural and controlled direct effects) to enable consideration of multiple mediators/confounders simultaneously and the use of linear and nonlinear predictive models for estimating mediation/confounding effects. Previous studies find that compared with non-Hispanic cancer survivors, Hispanic survivors are more likely to endure anxiety and depression after cancer diagnoses. In this paper, we applied MMA on MY-Health study to identify mediators/confounders and quantify the indirect effect of each identified mediator/confounder in explaining ethnic disparities in anxiety and depression among cancer survivors who enrolled in the study. We considered a number of socio-demographic variables, tumor characteristics, and treatment factors as potential mediators/confounders and found that most of the ethnic differences in anxiety or depression between Hispanic and non-Hispanic white cancer survivors were explained by younger diagnosis age, lower education level, lower proportions of employment, less likely of being born in the USA, less insurance, and less social support among Hispanic patients.     

Associations between Race and Eating Disorder Symptom Trajectories in Black and White Girls

Epidemiological research suggests racial differences in the presentation of eating disorder symptoms. However, no studies have examined associations between race and eating disorder symptom trajectories across youth and adolescence, which is necessary to inform culturally sensitive prevention programs. The purpose of the current study was to examine the trajectories of eating disorder symptoms from childhood to young adulthood and to examine whether race was associated with trajectory group membership. Data were drawn from 2,305 Black and White girls who participated in a community-based longitudinal cohort study (Pittsburgh Girls Study) examining the development of psychopathology. The child and adult versions of the Eating Attitudes Test assessed self-reported eating disorder symptoms at six time points between ages 9 and 21 years. Growth mixture modeling was used to examine developmental trajectories of dieting, bulimia/food preoccupation, and total eating disorder symptom scores. Given potential confounds with race and disordered eating, financial strain (i.e., receiving public assistance) and weight were included as covariates. Four to six distinct developmental patterns were found across eating disorder symptoms, including none, increasing, decreasing, or increasing-decreasing trajectories. Black girls had a greater likelihood of being in the decreasing trajectories for dieting, bulimia/food preoccupation, and total eating disorder symptom scores. White girls were more likely to follow increasing trajectories of dieting and total eating disorder symptom scores compared to Black girls. These results highlight the importance of examining the influence of racial background on eating disorder symptoms and the potential need for differences in the timing and focus of prevention interventions in these groups.     

Autonomic conditioning to monetary and social stimuli and aggression in children

Poor conditioning to punishment, such as loud tones or electric shock, has been proposed as an important factor involved in the etiology of aggressive and psychopathic behavior. However, it is not known whether the association holds when monetary or social stimulus is used as the unconditioned stimulus, and if aggressive individuals also have impaired conditioning to rewards. In this study, skin conductance responses in a conditioning task involving both monetary/social reward and punishment as unconditioned stimuli were assessed in 340 male and female 8‐ to 9‐year‐old children from the community. Children reported their reactive and proactive aggression using the Reactive and Proactive Aggression Questionnaire (RPQ; Raine et al., 2006). Results showed that monetary/social reward and punishment were effective in eliciting physiological classical conditioning in children, and that reduced reward conditioning was associated with high levels of proactive aggression in particular. Findings highlight the importance of distinguishing between reactive and proactive aggression when examining antisocial behavior in children, and suggest that reward‐oriented treatment programs may not be effective for children with more proactive, instrumental aggressive behavior.

     

选择与坚持:跨期选择与延迟满足之比较

做出选择与坚持选择是决策活动的两个重要阶段。跨期选择源于经济学领域对成人对发生在不同时间点的结果"做出选择"过程的研究;延迟满足则源于心理学领域对儿童为获得未来较大收益而抵制当前诱惑的"坚持选择"过程的研究。二者均致力于研究与时间相关的决策活动,从不同视角关注个体的冲动性与自我控制,但鲜见学者对二者异同的系统比较。本文着重从研究方法、认知机制与神经基础入手探讨了二者的异同,冀为两个研究领域协同发展、共同促进人类远见的培养与实践提供科学的理论支持。     

汉语阅读中词N+2的预视对高频词N+1加工影响的眼动研究

本研究采用边界范式,控制单字词N+1的预视加工负荷和词N+2首字的预视信息类型,探讨了汉语阅读中词N+2的预视对高频单字词N+1加工产生的影响。结果发现,当词N+1的预视为低加工负荷时,词N+2首字的预视对词N+1的加工产生了显著的影响;当词N+2首字的预视字与词N+1正字法相似,并且只呈现在副中央凹中时,显著的阻碍了词N+1随后的加工。结果表明,副中央凹中词N+2能够获得预视加工,可能获得正字法预视信息并对随后词N+1的加工产生了影响,并且这种影响受词N+1的预视加工负荷的调节。实验结果符合注意梯度指引模型的假设。
