东西方文化下的真实自我研究：一种关系的视角

真实自我反映了个体行为与其价值观、信仰、需求等内在状态的一致性程度, 分为特质真实与状态真实。在辨析了真实自我与自我认知、自我概念清晰性、自我一致性、正直、真诚等相关概念的异同, 并梳理该领域已有理论后, 提出真实自我表现或实现的文化差异, 即西方文化中的真实自我是自主动机驱动的, 而东方文化中的真实自我是关系要求驱动的。未来可以将“关系化”作为现象场, 以儒家传统思想为理智资源, 从理论建构、社会现象(新兴网络社交平台、社会变迁), 以及结合具体的研究方法(如跨文化比较、突显情境变化的方法)等方面开展研究。     

同伴特点如何影响人们的合作与冲突行为?

人类的生存繁衍依赖于人们之间的相互合作,合作与冲突行为的研究近年来成为心理学的研究热点。本研究通过实验程序操纵Chicken Game中博弈同伴的特点,考察个体在社会困境中面对不同特点同伴时的合作行为。结果发现：(1)同伴道义论组和功利论组总和解率没有显著差异,同伴竞争组和合作组的总和解率也没有显著差异。(2)在与道义论以及合作型的同伴互动时,个体的行为没有明显受到上次博弈反馈的影响。(3)当同伴为功利论时,相比于上次博弈个体选择和解而同伴选择进攻,双方都选择和解时个体在当前博弈中更倾向于和解;(4)在同伴竞争组中,相比于上次博弈个体选择进攻而同伴选择和解,双方都选择和解时被试在当前博弈中会更倾向于和解。实验结果表明个体在博弈任务中会受到同伴特点的影响,并且同伴在博弈中的行为特点的影响更为显著。本研究从同伴特点来考察个体的合作行为,揭示了影响个体博弈行为的一种因素。     

Infertility-Related Stress and Life Satisfaction among Chinese Infertile Women: A Moderated Mediation Model of Marital Satisfaction and Resilience

The present study investigated the effects of infertility on Chinese women’s life satisfaction. Infertile women (n?=?466) who were seeking medical help completed a survey that included the Fertility Problem Inventory (FPI), the Dyadic Adjustment Questionnaire (DAS), the Connor-Davidson Resilience Scale (CD-RISC), the Satisfaction with Life Scale, and demographic variables. We used a moderated mediation model to test our hypotheses, with life satisfaction as the dependent variable, representations about the importance of parenthood as the independent variable, the impact of infertility on life domains as a mediator, and marital satisfaction and resilience as moderators. Results showed that representations about the importance of parenthood and the impact of infertility on life domains are two main types of infertility-related stress, which could play independent roles in predicting life satisfaction. Representations about the importance of parenthood had a negative indirect effect on life satisfaction through the impact of infertility on life domains, and the indirect effect of the impact of infertility on life domains was moderated by marital satisfaction and resilience. Specially, representations about the importance of parenthood had a weaker indirect effect (through the impact of infertility on life domains) on life satisfaction in individuals with higher marital satisfaction or resilience. Therefore, the type of infertility-related stress and both marital satisfaction and resilience should be addressed in psychological interventions for women coping with infertility in mainland China.

     

得失情境下他人参照点及心理距离对自我-他人利益权衡的影响

以福利权衡率(WTR)为利他程度的指标, 通过3个实验逐步深入地考察了得失情境下他人参照点及心理距离对自我-他人利益权衡的影响。实验1的结果表明, 得失情境并未改变被试的WTR。实验2引入他人底线、现状和目标三个参照点变量, 发现被试获益情境下的WTR高于损失情境, 且WTR从高到低依次为他人临近底线、目标和现状; 他人临近底线时, 被试在获益情境下的WTR高于损失情境, 而他人临近现状和目标时, 个体在得失情境下的WTR无显著差异。实验3进一步引入心理距离变量, 发现心理距离较近他人的WTR高于较远他人, 且与得失情境和参照点发生了复杂的交互效应, 得失情境的主效应消失了, 但总体上并未改变实验2发现的参照点效应。这些结果对于更深入地理解得失不对称效应、三参照点理论及社会折扣和自我-他人决策差异研究的相关发现具有一定的启示意义。     

Decision-makers use social information to update their preferences but choose for others as they do for themselves

People's risky decisions are susceptible to the social context in which they take place. Across three experiments using different paradigms, we investigated the influence of three social factors upon participants' decisions: the recipient of the decision-making outcome (self, other, or joint), the nature of the relationship with the other agent (friend, stranger, or teammate), and the type of information that participants received about others' preferences: none at all, general information about how previous participants had decided, or information about a specific partner's preference. We found that participants' decisions about risk did not differ according to whether the outcome at stake was their own, another agent's, or a joint outcome, nor according to the type of information available. Participants did, however, adjust their preferences for risky options in light of social information.     

年老化对中文阅读眼动控制的影响:来自词长和语境预测性效应的证据

本研究通过对比老年与青年人在阅读中词长、词频和语境预测性效应上的差异,探讨中文阅读中眼动控制的年老化问题。结果发现:(1)词长的年龄主效应显著,注视时间和首次注视位置指标上年龄与词长的交互作用显著;(2)在注视时间指标上发现了显著的词频和语境预测性效应,年龄与语境预测性之间交互作用显著。综合而言,中文阅读中老年读者的词长效应和语境预测性效应不同于青年读者,由此可见,视觉功能和词汇加工功能衰退都是中文阅读眼动控制年老化的诱发原因。     

一在二中与即用是体——方以智对理学的回应

方以智多次提到“一在二中”,这也是其处理超越者与现实世界之关系的基本思路。在讨论“一”和“二”的关系时,方以智一反宋儒强调有本到末,由体达用的思维模式,转而把重心放在“二”上,甚至主张“止有后天,并无先天”,有以现实世界为先、为本的倾向。以此为基础,方以智对于理学所讨论的一系列重要问题予以了回应,也体现出了重视思辨和强调智识的一面。不过,方以智的回应颇有深受庄学和佛学影响的痕迹,与理学的主流观点有较大的不同。     

睡眠剥夺对风险决策的影响机制探讨

许多行业的决策者必须在睡眠不足的状态下做出选择与判断。睡眠剥夺是睡眠不足的实验室模型, 被证明能显著影响风险决策, 但内在机制不明。基于前人研究基础提出假设模型, 即睡眠剥夺通过影响个体的反馈加工、风险感知、抑制控制、决策理性, 进而影响风险决策。拟通过实验室研究与现场研究, 采用简单赌博任务、概率折扣任务、双选择Oddball任务等研究范式, 对比睡眠剥夺前后被试在执行上述实验任务时的行为差异, 同时比较执行控制网络、奖赏网络等脑功能网络连接强度, 以及任务诱发的FRN等脑电成分在睡眠剥夺前后的变化, 进而论证上述反应被试反馈加工等心理过程的行为-脑电-脑成像指标的变化与睡眠剥夺后被试风险决策变化的关系。研究结果将科学地解释睡眠剥夺影响风险决策的内在机制, 为进一步探讨如何规避睡眠不足导致的决策失误提供理论与实证依据。
