背外侧前额叶对主动遗忘负性社会反馈的作用：针对抑郁症的TMS研究

抑郁症患者的负性心境可能源于其抑制功能障碍。患者在主动遗忘负性材料时无法有效调用背外侧前额叶(the dorsolateral prefrontal cortex, DLPFC)等负责抑制控制的额叶脑网络。同时, 患者对社会信息的加工比对非社会信息的加工存在更明显的认知神经障碍, 很难主动遗忘对自己不利的社会反馈信息。为了提高抑郁症患者对负性社会反馈的主动遗忘能力, 本研究采用经颅磁刺激技术(transcranial magnetic stimulation, TMS), 考察抑郁症患者在左侧(n = 32)或右侧DLPFC (n = 30)被激活后其记忆控制能力的改变。结果表明, 当患者的DLPFC被TMS激活时, 他们对社会拒绝的回忆正确率与健康对照组(n = 31)无差异, 且TMS激活右侧DLPFC还改善了患者对他人的社会态度。本研究是采用TMS提高抑郁症患者主动遗忘能力的首次尝试, 研究结果不但支持了DLPFC与记忆控制功能的因果关系, 还为临床治疗抑郁症、创伤后应激障碍、药物成瘾等患者的记忆控制缺陷提供了明确的神经靶点。     

大学生主观童年创伤症状对抑郁的影响:抗挫折能力和外向性的多重中介效应

本研究将"童年创伤"定义为"个体14岁以前所经历的,站在主体的角度主观感受到的创伤性事件"。采用问卷调查法对302名大学生进行调查,通过定量加定性的方式探索了童年创伤与抑郁之间的关系。相关分析表明：主观童年创伤症状、外向性、抗挫折能力、抑郁之间两两显著相关;结构方程模型表明：主观童年创伤症状通过外向性、抗挫折能力完全、多重中介作用间接预测抑郁。本研究结果在理论和实践层面对大学生抑郁问题的预防和干预工作提供重要的借鉴依据。     

Action Generalization Across Group Members: Action Efficiency Matters

Actions are usually generalized among social group members. Importantly, the efficiency of an action with respect to achieving an external target determines action understanding, and it may have different degrees of social relevance to social groups. Thus, this study explored the role of action efficiency in action generalization. We used computer animations to simulate actions in social groups initiated by visual action cues or category labels, and we measured differences in response times between identifying actions that were and were not consistent with group members, without explicit requirements regarding generalization. It was found that in both visually introduced and explicitly labeled social groups, when the group members acted inefficiently toward the external object, perceivers identified group-consistent actions faster than group-inconsistent actions, indicating that the exemplars' common inefficient actions are generalized to the unknown ingroup member, accordingly facilitating the identification of expected consistent inefficient action (Experiment 1). As this effect was not present when removing social group cues, it was determined to be specific to social groups (Experiment 2). Importantly, such generalization was not observed when the identical action was deemed efficient toward the external object (Experiment 3) and was specific to the demonstration of the action being completed by multiple group members rather than being repeated twice by one group member, supporting the group-based inference and ruling out the possibility of the increased memorability of inefficient actions leading to more generalization relative to efficient actions (Experiment 4). Therefore, the efficiency of an action bounds the generalization of the action across social group members through a process that is spontaneous and implicit. This constrained action generalization may be due to inefficient actions being represented as culture-specific conventional forms.     

中国人社会善念的心理结构

为探究中国人社会善念的心理结构, 研究采用人格词汇法, 在开放调查收集的词汇中选取代表社会善念的心理词语, 确立了社会善念词库。通过两次探索性因素分析和验证性因素分析, 得到包含18个人格特质词的社会善念词汇评定量表和包含17项描述的社会善念自陈量表。研究表明, 中国人的社会善念是一种具有二阶四因素结构的人际特质, 二阶是指宜人特质和外倾特质, 四因素分别是善良尊重、谦和恭逊、包容理解和积极开放。     

未来时间洞察力与大学生职业决策自我效能感的关系:领悟社会支持与自尊的链式中介

为考察未来时间洞察力对大学生职业决策自我效能感的影响及其作用机制,本研究采用未来时间洞察力量表、领悟社会支持量表、自尊量表和职业决策自我效能感量表,对756名高校学生进行调查。结果表明:(1)未来时间洞察力、领悟社会支持、自尊、职业决策自我效能感两两之间存在显著正相关;(2)社会支持和自尊在未来时间洞察力与职业决策自我效能感之间起显著的中介作用。具体为三条中介路径:一是社会支持的单独中介作用; 二是自尊的单独中介作用; 三是社会支持和自尊的链式中介作用。研究揭示了未来时间洞察力与大学生职业决策自我效能感的关系及其作用机制,拓展了大学生职业决策自我效能感的影响因素,对大学生的职业指导具有一定的现实意义。

The Association between Home Environment and Quality of Life in Children and Adolescents in Hangzhou City,China

To investigate the influence of the home environment, defined as family socioeconomic status (SES) (parent education level, household income), student resource-mediated SES (access to nutritional resources and cognitively stimulating experiences), reading ability, and difficulty with homework on quality of life in children and adolescents residing in urban and suburban areas in Hangzhou City, Zhejiang Province, China. This study included 3200 Grade 3–6 students from 8 elementary schools in Hangzhou City. Assessments included questionnaires that evaluated student quality of life, family SES, resource-mediated SES (dietary behavior and the home literacy environment), reading ability, and difficulty with homework. The effects of the home environment on student quality of life were analyzed by univariate analysis, multiple linear regression analysis, and structural equation modeling. Overall, 80.6% of students had a medium or better quality of life. Young age (Grade 3 or 4), female sex, household income of 10000–15000 RMB, high breakfast consumption, daily intake of fruit, a balanced diet, and good reading habits were positively correlated with student quality of life (P?<?0.05), while overuse of electronic devices was negatively correlated with quality of life (P?<?0.05). Dietary behaviors, home literacy environment, and student reading ability and difficulty with homework directly affected quality of life. Family SES indirectly affected student quality of life. Children and adolescents in China should have access to good nutrition and cognitively stimulating experiences to enhance their well-being and provide them with social and academic advantages.

     

Effects of containment and closure policies on controlling the COVID‐19 pandemic in East Asia

Growing efforts have been made to pool coronavirus data and control measures from countries and regions to compare the effectiveness of government policies. We examine whether these strategies can explain East Asia’s effective control of the COVID‐19 pandemic based on time‐series data with cross‐correlations between the Stringency Index and number of confirmed cases during the early period of outbreaks. We suggest that multidisciplinary empirical research in healthcare and social sciences, personality, and social psychology is needed for a clear understanding of how cultural values, social norms, and individual predispositions interact with policy to affect life‐saving behavioural changes in different societies.     

自动观点采择：内隐心智化与潜心智化的争议

自动观点采择现象已有很多研究证实, 但其产生机制还存在争议。目前存在内隐心智化与潜心智化两种观点：前者认为自动观点采择是自发采择他人视角的领域特殊加工; 而后者提出自动观点采择实质为反射性注意定向、位置的空间编码等领域一般加工, 模拟了心智化在社会环境中的作用。在内隐心智化和潜心智化可独立或共同运行的基础上, 提出了内隐心智化和潜心智化协同作用模型。未来研究应借助先进的技术手段研究多样的被试群体, 探索自动观点采择的作用机制。     

技术信任和领导信任对企业员工新技术接受的影响

在当今知识经济时代, 新技术的采用对于企业提高核心竞争力至关重要。如何使员工面对新技术带来的风险和不确定性, 信任并接受新技术是企业新技术推广的重要问题。现今学界虽已关注到信任在新技术采用这一过程中的积极作用, 但仍缺乏相关的理论和实证研究, 特别是对于其内在心理机制的解释。为弥补这一研究的不足, 本研究通过分析企业新技术推广情境下, 技术信任和领导信任对员工新技术接受的影响, 并引入了感知风险性与技术自我效能感作为中介变量, 探寻信任影响的内在机制。此外, 还进一步探讨企业文化的调节作用, 从而建构信任与企业员工新技术接受的理论模型, 为企业新技术的推广提出合理建议。
