情绪、刺激呈现方式对现实性监控的影响

以往的来源记忆研究大多以词汇和图形等为实验材料,意义丰富的声音材料尚未涉及.本实验采用中国情感数据声音系统的声音为材料,分析了情绪效价、编码和测验阶段的刺激呈现方式等对区分听觉和想象两种不同来源的现实性监控的影响.实验含编码和测验两阶段,编码任务是听声音或根据提供的文字想象声音,并判断刺激的情绪效价;测验阶段则要求被试听声音或根据文字想象声音,并做出“听过”、“想象过”或“新项目”的三项选择判断.结果显示,想象刺激低于听觉形式获得刺激的提取成绩;情绪效价显著影响听过项目的提取绩效;编码与测验刺激呈现方式匹配条件的来源监控成绩较高;恐惧刺激的判断快于厌恶刺激.上述结果表明:内部来源与外部来源提取是两种不同的活动,情绪效价对区分上述两种任务的现实性监控具有调节作用,编码与提取刺激呈现方式匹配与否对提取结果的影响明显,恐惧刺激的加工相对优先.     

A latent profile analysis of Asian American men's and women's adherence to cultural values

The goal of this study was to identify diverse profiles of Asian American women's and men's adherence to values that are salient in Asian cultures (i.e., conformity to norms, family recognition through achievement, emotional self-control, collectivism, and humility). To this end, the authors conducted a latent profile analysis using the 5 subscales of the Asian American Values Scale-Multidimensional in a sample of 214 Asian Americans. The analysis uncovered a four-cluster solution. In general, Clusters 1 and 2 were characterized by relatively low and moderate levels of adherence to the 5 dimensions of cultural values, respectively. Cluster 3 was characterized by the highest level of adherence to the cultural value of family recognition through achievement, whereas Cluster 4 was typified by the highest levels of adherence to collectivism, emotional self-control, and humility. Clusters 3 and 4 were associated with higher levels of depressive symptoms than Cluster 1. Furthermore, Asian American women and Asian American men had lower odds of being in Cluster 4 and Cluster 3, respectively. These findings attest to the importance of identifying specific patterns of adherence to cultural values when examining the relationship between Asian Americans' cultural orientation and mental health status.     

Birth cohort changes in Chinese adolescents' mental health

In China, rapid economic growth and increasing social problems constitute two basic characteristics of contemporary social change. During the process of dramatic social change, an emerging question is how adolescents' mental health has changed across birth cohorts. The present paper reviews four studies of crosstemporal meta-analysis conducted by us. By meta-analysis of previous literature, we examined changes in mean scores on mental health measures over time (from the early 1990s to the mid-2000s). It was found that since the early 1990s, Chinese adolescents' mental health deteriorated across birth cohorts, shown in increased scores on the negative indicators of mental health (e.g. mental problems, anxiety, and depression), whereas self-esteem as a positive trait decreased. The dropping trend in Chinese adolescents' mental health could be attributed to social change, especially increasing social problems. Therefore, adequate attention must be paid to potential influences of social change on individuals' psychological development.     

如何削弱产品来源国效应*—— 产品信息呈现方式的影响研究

以元认知和双系统模式的心理学理论为背景, 研究了分析式系统对来源国效应的削弱, 检验了产品信息呈现方式对来源国效应的调节作用。三个研究说明, 分析式系统的启动可以有效削弱来源国效应; 特定的产品信息呈现方式所引起的消费者信息处理不流畅性感知会激发消费者的元认知困难, 从而使他们在产品评价过程中主要依赖分析式系统, 达到削弱来源国效应的目的; 并不是所有能引起信息处理不流畅性的产品信息呈现方式都能削弱来源国效应, 过于复杂的呈现方式由于给消费者带来过多认知负荷, 反而不能成功启动分析系统, 从而无法削弱产品来源国形象对消费者产品评价的影响。     

汉字字谜任务中限制解除的电生理机制

尽管“限制解除”作为一种顿悟问题解决的关键途径早在上世纪90年代就被德国心理学者Knoblich及其同事提出, 但学界对于“限制解除”所包含的信息加工程序、阶段以及相应的脑认知过程却并未有进一步的探讨和细化。本文从“限制解除”的理论角度出发, 以答案提示催化的“诱发式”字谜解决顿悟为例, 首次提出了一个关于“诱发式”限制解除过程的信息加工阶段初步构想。该构想认为：顿悟问题解决中的“诱发式”限制解除过程包含3个不同的信息加工阶段。第一阶段是以早期注意参与为特征的冲突信息的预警或预处理过程; 第二阶段是以新旧思路交替为特征的关键限制解除过程, 鉴于这个过程以基本问题表征空间的拓展为特征, 因此我们推测右脑的活动很有可能在这个过程中占据主导地位; 第三阶段是以自上而下的控制加工为特征的重新整合过程。脑电研究数据部分地支持了本研究的假设, 发现了上述第一阶段在脑电变化上体现为顿悟性限制解除所伴随的N100/P200复合体; 第二阶段体现为P300在300~400 ms的时间窗内的地形图分布及差异波; 而第三阶段则体现为N400在400~800 ms内的变化。脑电结果还证实：在第二阶段也就是限制解除的关键阶段, 右脑的活动明显强于左脑, 提示基本问题空间的拓展可能更多地依赖于右脑, 而在第三阶段也就是信息的重新整合阶段则表现出相反的半球偏侧化倾向。上述发现有可能为进一步认识和理解顿悟中“限制解除”的脑认知机理提供了新的见解。     

Prediction of intrinsic motivation and sports performance using 2 x 2 achievement goal framework

The purpose of this study was to examine the influence of 2 x 2 achievement goals on intrinsic motivation and performance in handball. Participants were 164 high school athletes. All completed the 2 x 2 Achievement Goals Questionnaire for Sport and the Intrinsic Motivation subscale of the Sport Motivation Scale; the coach for each team rated his athletes' overall sports performance. Using simultaneous-regression analyses, mastery-approach goals positively predicted both intrinsic motivation and performance in sports, whereas performance-avoidance goals negatively predicted sports performance. These results suggest that athletes who pursue task mastery and improvement of their competence perform well and enjoy their participation. In contrast, those who focus on avoiding normative incompetence perform poorly.     

Aligning inside and outside perspectives of the self: A cross‐cultural difference in self‐perception

Past research shows that European Americans tend to take a first‐person perspective to understand the self and are unlikely to align the inside look with the outside gaze, whereas Asians tend to take a third‐person perspective and are likely to shift their inside look in the direction of the outsize gaze. In three experiments, we compared Asians and European Americans' self‐perceptions when the presence of their parents in the background of self‐perception was primed or otherwise. Without the priming, both European Americans and Asians viewed themselves more positively from their own perspective than from their parents' perspective. With the priming, only Asians lowered the positivity of their self‐perceptions to match the perceived positivity of the self in the parents' perspective. These results suggest that Asians do not have a static, passive tendency to assimilate their self‐views into the perceived external assessments of the self. Rather, their self‐views are fluid and flexible.     

分段是视频学习的有效方式吗?

教育心理学中的分段原则认为,将视频学习材料分割成几个小片段进行学习的效果更好。以往关于分段的研究通过两个角度的操纵考察了分段在学习中的作用,一方面是交互性角度,学习者自己控制的分段及系统分段;另一方面是结构性角度,分段是在任意时间点划分和有意义时间点上划分。通过对以往研究结果的整理发现,大部分研究证明分段学习相较于连续学习的成绩更好,并且能降低学习者在学习过程中的感知难度, 提高积极的情感状态,但是对心理努力的影响比较微弱。研究者们从事件分割理论和认知负荷理论的视角对分段的效果做出了解释。未来研究需要继续关注分段的边界条件、拓宽研究的范围、探究分段的认知神经基础等不断完善分段原则在教学中的应用。     

有“新”同享：共有消费促进对不熟悉产品的选择*

共有消费是多位消费者共同参与并承担开销的一种常见的消费活动。本研究基于风险转移理论, 探究了消费情境(单独消费vs.共有消费)对不熟悉产品偏好的作用机理及边界条件。通过5个实验, 结果发现：相比于单独消费情境下的消费者, 在共有消费情境下的消费者更愿意尝试不熟悉的产品。原因在于共有消费情境会转移消费风险, 使得消费者对不熟悉产品的感知风险降低。但是该效应仅发生于产品风险较低的产品。同时, 当共有消费群体的关系较为疏远时, 该效应会消失甚至逆转。     

认知负荷与编码方式影响小学数学学业不良生的前瞻记忆及其成分

通过两个实验探讨认知负荷对小学数学学业不良生前瞻记忆及其成分的影响, 以及是否可以通过执行意向编码提高其前瞻记忆及其成分的成绩。实验1结果显示数学学业不良生前瞻记忆、前瞻成分及回溯成分正确率显著低于数学学优生, 高认知负荷条件前瞻记忆、前瞻成分及回溯成分的正确率显著低于低认知负荷条件; 实验2结果显示执行意向编码条件下, 数学学业不良生前瞻记忆成绩显著好于标准编码条件, 前瞻成分和回溯成分的正确率高于标准编码条件。结果表明数学学业不良生前瞻记忆及其成分表现差于数学学优生; 无论认知负荷高低, 执行意向编码均可通过提升前瞻成分和回溯成分改善数学学业不良生前瞻记忆表现。
