Mapping differential responses to cognitive training using machine learning

We used two simple unsupervised machine learning techniques to identify differential trajectories of change in children who undergo intensive working memory (WM) training. We used self‐organizing maps (SOMs)—a type of simple artificial neural network—to represent multivariate cognitive training data, and then tested whether the way tasks are represented changed as a result of training. The patterns of change we observed in the SOM weight matrices implied that the processes drawn upon to perform WM tasks changed following training. This was then combined with K‐means clustering to identify distinct groups of children who respond to the training in different ways. Firstly, the K‐means clustering was applied to an independent large sample (N = 616, M_age = 9.16 years, range = 5.16–17.91 years) to identify subgroups. We then allocated children who had been through cognitive training (N = 179, M_age = 9.00 years, range = 7.08–11.50 years) to these same four subgroups, both before and after their training. In doing so, we were able to map their improvement trajectories. Scores on a separate measure of fluid intelligence were predictive of a child's improvement trajectory. This paper provides an alternative approach to analysing cognitive training data that go beyond considering changes in individual tasks. This proof‐of‐principle demonstrates a potentially powerful way of distinguishing task‐specific from domain‐general changes following training and of establishing different profiles of response to training.     

人口统计学特征对公共服务动机有什么影响?来自元分析的证据

采用元分析方法探讨人口统计学特征与公共服务动机之间的关系。经筛选, 共纳入138篇492个独立样本(N = 1078442)。结果发现, 性别、年龄、教育程度、组织任期、工作任期、职位等级和收入与公共服务动机之间均呈显著的正相关关系, 且与公共服务动机不同维度之间的关系均存在差异, 婚姻状况与公共服务动机间不存在显著的相关关系。此外, 公共服务动机测量工具、测量时间点和文化背景对部分人口统计学特征与公共服务动机之间的关系有调节作用。研究结果为人口统计学特征如何影响公共服务动机提供了较为精确的估计, 对于发展公共服务动机理论, 激励员工工作积极性, 提高公共部门服务水平都有重要意义。     

社交媒体信任对重大突发公共卫生事件中公众网络谣言自治行为的影响

从社会心理学视角、以社交媒体信任为切入点,基于新冠肺炎疫情,考察公众在重大突发公共卫生事件中网络谣言自治行为的心理机制。采用问卷方法对963名成年居民进行调查。结果表明:(1)公众对官方社交媒体的信任既能直接促进公众的辟谣行为,也能通过增强公众对战胜疫情的信心产生间接影响;(2)公众对官方社交媒体的信任影响公众对自媒体的信任,但自媒体信任不能独立于官媒信任影响辟谣行为。因此,我国社交媒体存在着两个舆论场且官方舆论占主导地位,及时、有效的官方报道不仅能提高公众对战胜疫情的信心,也能促进公众网络谣言自治,进而实现网络谣言治理主体的多元化。     

线索冲突情境下幼儿对不同领域知识的选择性信任特点

探讨幼儿在准确性线索和共识线索冲突情境下对自然与社会领域知识的选择性信任特点。实验1探究幼儿在线索冲突情境下对自然领域知识的选择性信任,选取88名4~6岁幼儿,采用对物品命名的方法,结果发现4岁幼儿依据共识线索进行信任判断,而5~6岁幼儿依据准确性线索进行信任判断;实验2探究幼儿在线索冲突情境下对社会领域知识的选择性信任,选取94名4-6岁幼儿,采用对人格特质命名的方法,结果发现4岁幼儿依据共识线索进行信任判断,5岁幼儿对两类线索没有做出偏向性选择,6岁幼儿依据准确性线索进行信任判断。实验3采用被试内设计,探讨5岁幼儿对两个领域知识的选择性信任,验证了实验1和实验2的相关结果。结论:在线索冲突情境下幼儿对不同领域知识的选择性信任具有不同的年龄发展特点。     

精神分析视域下的身心观

身心关系问题是人类长期探究的重要议题。精神分析学家对身心关系具有诸多独特见解,具体表现为：身体是心理的基础,身体是心理的象征,身体与心理的交织。此三种观点不仅反映出不同精神分析学家在方法论、认识论以及本体论上的差异,也蕴含着精神分析不同流派的理论脉络。厘清精神分析视域下的身心观,既有助于自然科学心理学与人文科学心理学在精神分析中寻求一种主客交织的研究视角,也可为心理学和其他学科领域研究身心关系问题提供新的切入点。     

“己之所欲”还是“成人之美”？解释水平视角下个体赠送-接受礼物的偏好不对称性

解释水平理论被广泛应用于消费研究领域。本研究以解释水平理论为理论基础,采用情境问卷调查方法,通过5个实验探讨个体赠送与接受礼物时是否存在性别和角色偏好的不对称性。结果发现,一般情境下,受性别因素影响,男生偏好赠送和接受工具性礼物,女生偏好赠送和接受表达性礼物。但随着心理距离（社会距离和空间距离）的拉近,个体的解释水平降低,更关心他人的喜好和需求,赠送者会更基于接收者的偏好进行礼物选择。     

论公共行政管理的伦理基础——一个公共伦理分析视角

当代中国正处在以城市化为主导的社会转型的关键时期,社会出现了种种不协调,需要相应价值尺度来引导。行政管理本身不是最终目的,它是传达人民的需求与愿望,并保证这些需求和愿望能够通过国家控制反映出来。长期以来,行政管理学界高扬效率、忽视伦理的主题定位,在一定程度上阻碍了行政管理学研究向纵深领域的发展。公共行政管理从产生时起就与某种伦理价值观相联系;公共行政管理的主要伦理规范有公益至上、有害不为、慎用权力、社会责任、平等竞争、增进信任。这些规范为公共行政管理奠定了伦理基础。     

What do you think I think you think?: Strategic reasoning in matrix games

In reasoning about strategic interpersonal situations, such as in playing games, an individual's representation of the situation often includes not only information about the goals and rules of the game, but also a mental model of other minds. Often such mental models involve a hierarchy of reflexive reasoning commonly employed in social situations ("What do you think I think you think..."), and may be related to the developmental notion of 'theory of mind'. In two experiments, the authors formally investigate such interpersonal recursive reasoning in college-age adults within the context of matrix games. Participants are asked to predict the moves of another player (experimenter's confederate) in a two-choice, sequential-move game that may terminate at various stages with different payoffs for each player. Participants are also asked to decide optimally on their own moves based on the prediction made. Errors concerning the prediction, or translation of those predictions into decisions about one's action, were recorded. Results demonstrate the existence of a "default" mental model about the other player in the game context that is dynamically modified as new evidence is accumulated. Predictions about this other player's behavior are, in general, used consistently in decision-making, though the opponent tends to be modeled, by default, to behave in a myopic fashion not anticipating the participant's own action.     

Measuring Chinese psychological well-being with Western developed instruments

We explored the possibility of applying 4 psychological scales developed and commonly used in the West to Chinese culture. The participants, 273 Chinese and 302 Americans, completed measures of self-esteem (Self-Esteem Scale; Rosenberg, 1965), depression (Center for Epidemiologic Studies-Depression Scale; Radloff, 1977), social support (Multidimensional Scale of Perceived Social Support; Zimet, Dahlem, Zimet, & Farley, 1988), and suicidal ideation (Scale for Suicide Ideation; Beck, Kovacs, & Weissman, 1979). All scales were found to be reliable and valid cross culturally. Comparative analyses suggest that gender differences on all 4 scales are smaller among the Chinese than the Americans. Americans were more likely to score higher on the socially desirable scales (self-esteem and social support) and lower on the socially undesirable scale (suicidal ideation). However, no cultural differences were found in this study on the measure of depression. Results suggest that, with a few considerations or potential modifications, the current measures could be used in Chinese culture.
