How Incidental Confidence Influences Self‐Interested Behaviors: A Double‐Edged Sword

The present research investigates how incidental confidence influences self‐interested behaviors. It is well established that being in a psychological state of lower confidence causes people to experience psychological aversion that they are motivated to reduce. We study the transfer effect of confidence; people strive to compensate for lower confidence in one domain by obtaining higher status in other unrelated domains. Prior research has linked money with status and suggested that money can increase confidence. Building on this research, we proposed and showed in four experiments that lower incidental confidence increased self‐interested behaviors that brought financial gains. Drawing on research on competitive altruism, we also predicted and found that when altruism, rather than money, was seen as the primary source of status, the effect of incidental confidence reversed such that lower incidental confidence decreased self‐interested behaviors. Data ruled out alternative explanations and provided consistent evidence for the proposed compensatory mechanism. We also discussed theoretical and practical implications of the present research.

二级项目题组混合IRT模型及其稳健权重估计

在心理测量和教育测量中,二级项目和题组项目是两类常见的项目类型。由这两种项目混合构成的测试在实践中有着重要的应用。被试在答题时,由于个人的潜在能力和项目难度不匹配,常常会产生异常反应,这些异常反应会影响IRT中潜在特质估计的准确性。仿真实验证明,二级项目题组混合IRT模型的稳健估计方法在出现异常值的情况下,能够比极大似然估计对被试的潜在特质做出更加准确的估计,能够满足实际测试的需求。     

Unsatisfied relatedness,not competence or autonomy,increases trait anger through the right amygdala

Anger is a common negative emotion in social life. Behavioral research suggests that unsatisfied relatedness, autonomy, and competence are related to anger. However, it remains unclear whether these unsatisfied needs all contribute to anger or just a particular unsatisfied need is the main source of anger. In addition, little is known about the neural substrate between unsatisfied needs and anger. To address these two questions, we used voxel-based morphometry (VBM) to explore the neural substrate underlying the relation between unsatisfied needs and trait anger. Behaviorally, we found that although all three unsatisfied needs were correlated with trait anger, unsatisfied relatedness was the only factor that was uniquely related to trait anger. Neurally, the gray matter volume of the right amygdala was correlated with trait anger, which fits nicely with the role of the amygdala as a core region for processing anger. Importantly, the right amygdala mediated the total effect of unsatisfied relatedness on trait anger, even after controlling for general personality dispositions. Our results contribute to the theoretical conceptualization of anger by elucidating the unique role of unsatisfied relatedness in anger and the neural substrate underlying such relation.     

Norms of valence,arousal, concreteness,familiarity, imageability,and context availability for 1,100 Chinese words

In the present study, we collected valence, arousal, concreteness, familiarity, imageability, and context availability ratings for a total of 1,100 Chinese words. The ratings for all variables were collected with 9-point Likert scales. We tested the reliability of the present database by comparing it to the extant Chinese Affective Word System, and performed split-half correlations for all six variables. We then evaluated the relationships between all variables. Regarding the affective variables, we found a typical quadratic relation between valence and arousal, in line with previous findings. Likewise, significant correlations were found between the semantic variables. Importantly, we explored the relationships between ratings for the affective variables (i.e., valence and arousal) and concreteness ratings, suggesting that valence and arousal ratings can predict concreteness ratings. This database of affective norms will be a valuable source of information for emotion research that makes use of Chinese words, and will enable researchers to use highly controlled Chinese verbal stimuli to more reliably investigate the relation between cognition and emotion.

Motion direction discrimination training reduces perceived motion repulsion

Participants often exaggerate the perceived angular separation between two simultaneously presented motion stimuli, which is referred to as motion repulsion. The overestimation helps participants differentiate between the two superimposed motion directions, yet it causes the impairment of direction perception. Since direction perception can be refined through perceptual training, we here attempted to investigate whether the training of a direction discrimination task changes the amount of motion repulsion. Our results showed a direction-specific learning effect, which was accompanied by a reduced amount of motion repulsion both for the trained and the untrained directions. The reduction of the motion repulsion disappeared when the participants were trained on a luminance discrimination task (control experiment 1) or a speed discrimination task (control experiment 2), ruling out any possible interpretation in terms of adaptation or training-induced attentional bias. Furthermore, training with a direction discrimination task along a direction 150° away from both directions in the transparent stimulus (control experiment 3) also had little effect on the amount of motion repulsion, ruling out the contribution of task learning. The changed motion repulsion observed in the main experiment was consistent with the prediction of the recurrent model of perceptual learning. Therefore, our findings demonstrate that training in direction discrimination can benefit the precise direction perception of the transparent stimulus and provide new evidence for the recurrent model of perceptual learning.     

情绪与决策：躯体标记假设及其研究新进展

人类的决策被广泛认为是一个理性的和认知主导的过程,因此在决策研究中,任何形式的情绪都被避免。最近,一些神经科学的研究显示,情绪是人类决策中的一部分,它不可以与认知分析过程相分离,并且有些时候,情绪甚至在决策过程中起着重要的作用。躯体标记假设就提供了一个情绪如何影响人们决策的神经解剖和认知的框架,其核心为决策受躯体状态（或标识信号）所影响,躯体状态来源于生物调节过程,包括情绪和情感过程。该文章介绍了何为躯体标记假设,躯体标记假设的实验研究,以及研究中的新进展。

阅读能力个体差异的遗传基础—— 双生子研究的元分析

阅读能力的个体差异来源是行为遗传学的研究焦点之一。文章通过对80个阅读双生子研究的元分析发现：(1)遗传对阅读及其加工过程、基本认知技能具有中等强度影响; (2)不同阅读加工成分既受到共同遗传因素的作用, 又同时受到特异遗传因素的影响。(3)阅读与一般认知能力、数学能力在遗传上存在中等强度相关。这些结果表明了双生子研究对探索阅读的遗传机制具有分子遗传学所不可替代的价值, 文章还提出了如提升行为表型的测查质量等对未来研究的具体建议。
