"不明现象"终会明

笔者手中有这样一本出版物。这是前些年某省级科学技术出版社推出的一本科普读物,名曰:《人类面临不明现象》,从其文字的通俗易懂、生动有趣、引人入胜的特点来看,它的读者对象正是广大青少年。编著者在该书的前言中要求读者在阅读时"既不自囚于现代科学所能提供的认识客观世界的'取     

前瞻记忆的情绪一致性反转效应

采用经典双任务实验范式,探讨前瞻记忆的情绪一致性效应及其理论模型。情绪电影片段诱发被试高兴或悲伤情绪后,观察被试在高兴、悲伤和自然情绪状态下的前瞻记忆任务和当前任务的成绩。结果发现,情绪一致性前瞻记忆出现反转效应,即在高兴背景下前瞻记忆负性词比正性词成绩好,在悲伤背景下前瞻记忆正性词比负性词成绩好。实验结果支持前瞻记忆的注意—搜索模型,不支持自动激活模型。     

The Organizational Principles of Online Political Discussion: A Relational Event Stream Model for Analysis of Web Forum Deliberation

The structure of online political discussion has proven important to deliberative democracy. However, the organizational mechanisms of the structure receive little attention in scholarship. This study employed a random‐effects relational event model to differentiate and examine the effects of a set of organizational principles in web forum discussions. By analyzing more than 175,000 forum replies, the study found that cross‐ideological debate is an independent organizational mechanism even when accounting for the effects from common interests, opinion congruity, purely structural effects, and conversational norms. These findings differ from the selective exposure thesis and previous incidental claims of political disagreement. In addition, the findings indicate that endogenous mechanisms and opinion congruity could influence the tendency of cross‐ideological debate to varying degrees.     

亲子互动中游戏参与方式、情感交流和儿童心理理论的关系

本研究通过亲子互动游戏观察来考查亲子游戏参与方式、情感交流与儿童心理理论发展的关系。实验结果如下:第一,控制了年龄因素后,儿童的亲子游戏参与方式中的主动参与和建议游戏两种方式与儿童心理理论发展之间存在显著的相关;而对于母亲来说,指导游戏的参与方式和儿童心理理论发展存在显著相关。第二,控制了年龄因素之后,儿童情感交流方面的分享积极情感和心理理论发展之间存在显著相关。而母亲这方面的指标和儿童心理理论发展没有显著相关。文章对上述结果进行了分析讨论。     

Upward intergenerational influences on parents' innovativeness and innovation adoption: A comparative study of single‐ and multiple‐child families

In the marketing and consumer behavior literature, there has been a growing attention on upward intergenerational influences, or reverse socialization, which is largely because of children's increasing influences on family decisions. This paper hypothesizes different patterns of upward intergenerational influences in single versus multiple‐child families, controlling for peer and spousal influences. We found that young adult single children had a direct positive influence on their parents' innovation adoption behavior, but not a significant influence on their parents' overall innovativeness, whereas young adult children with siblings had a different effect: Their innovativeness had a significant positive influence on their parents' overall innovativeness, but not a direct impact on their parents' innovation adoption.     

Effect of Poverty on Mental Health of Children in Rural China: The Mediating Role of Social Capital

Underprivileged children are a relatively special vulnerable group in rural China, but the relationship between poverty and children’s mental health has been rarely examined. This study aimed to investigate the effect of poverty on children’s mental health and the mediating role of social capital in their family, peer, school, and community level. Data used in this study were collected in 2015 from a school-based survey of 1314 children in grades 4–9 through a multi-stage cluster random sampling method in Xiushui, a poverty-stricken city in Mainland China. The result of structural equation modeling indicated that poverty elicited a significant predictive effect on children’s negative and positive mental health. Family social capital and peer social capital played intermediary effects between poverty and children’s mental health. However, the mediating effects of school and community social capital are not significant. The implications of these findings on theory, social policy, and social work services were also discussed.

     

Unconscious integration of pointing relation between two masked arrows

In the present study, by using a briefly masked prime display paradigm, we investigated whether the pointing relation (same or different) between two unconsciously perceived arrows in the prime could be processed. Since only motor response priming can reflect unconscious processing of two arrows’ pointing-direction relation (i.e., a relational integration), we could distinguish the motor response priming from the visual priming in this study which in other studies were not separated. We also manipulated the prime-to-target stimulus onset asynchronies (SOA) by using a 70?ms and a 180?ms SOA. In this experiment, two masked arrow signs pointing in the same or different directions (> > or > <) were simultaneously presented in the prime, followed by two arrow symbols also pointing in the same or different directions in the target. The participants were asked to decide whether the two arrows in the target were pointing in the same or different directions. The results did not show any visual priming effect, but did show that the unconsciously perceived pointing relation in the prime elicited a positive motor response priming effect in RT under the 70?ms SOA condition, and a negative motor response priming effect in accuracy under the 180?ms SOA condition. The results were discussed in terms of self-motor-inhibition (or mask-triggered inhibition) and attention mechanisms. Overall, this study indicated that the pointing relation between the two subliminal arrows in the prime could influence the subsequent responses to the target and suggested that people can integrate unconsciously perceived information.     

拟人化:从“它”到“他”

拟人化是将人类特征、动机、意向或心理状态赋予非人对象的心理过程或者个体差异。拟人化的产生受到激发主体知识、效能动机和社会动机的影响,现有研究包括对自然、超自然、动物、机器、品牌和产品等的拟人化。对自然的拟人化能够促进环境保护行为,对动物、机器、品牌和产品的拟人化则形式多样、后果复杂。未来研究的焦点可能在人-机器人交互以及拟人化与可爱的关系问题上。     

内隐情绪加工对返回抑制效应的调节

为探讨内隐情绪加工是否会对返回抑制产生影响,采用线索靶子范式,以情绪性面孔图片作为目标,要求被试完成定位任务。结果发现,行为数据和脑电数据均显示了显著的返回抑制效应;N1成分上情绪效价和线索有效性的主效应及交互作用均显著,有效线索条件下情绪目标诱发的波幅显著大于中性目标;N170成分上线索有效性主效应显著,相较于N1成分,N170成分在有效线索上波幅更小,在无效线索上波幅更大。实验结果表明返回抑制效应受到内隐情绪加工的调节,提示该效应来源于早期的知觉抑制,支持知觉抑制理论。     

母亲抑郁对青少年抑郁的影响:亲子关系的中介作用与青少年消极情绪性的调节作用

对1708名八年级青少年（平均年龄14.30±0.48岁,男生852名）及其母亲（平均年龄39.17±2.47岁）的抑郁症状、母子关系和青少年消极情绪性进行测量,考察了母亲抑郁对青少年抑郁的影响机制。结果发现：（1）母亲抑郁能够正向预测青少年的抑郁;（2）母子关系在母亲抑郁与青少年抑郁之间起中介作用,母亲抑郁既能增加母子冲突的强度,也能降低母子亲合水平,进而导致青少年的抑郁;（3）青少年消极情绪性在母亲抑郁影响青少年抑郁的中介机制中起调节作用,仅在高消极情绪性的青少年中,母子冲突能够显著预测青少年的抑郁;但消极情绪性不能调节母子亲合对青少年抑郁的影响;（4）母亲抑郁影响青少年抑郁的有调节的中介模型不存在性别差异。
