惩罚对学习时间分配中决策与绩效的影响*

学习时间分配中的学习决策及其如何影响后续学习绩效是学习心理研究的重要领域。但对惩罚学习条件下,学习者是如何调整学习策略的,以及这种调整与后续学习绩效之间的关系尚不明确。本研究发现,奖励和惩罚条件下,参与者都会更多地选择高分的项目进行学习。在学习时间分配上,奖励组和惩罚组都倾向于将时间更多地分配到困难和高分的项目。但惩罚条件下参与者对低分项目的选择比例显著低于奖励条件,这表明惩罚影响学习者的学习策略。而且惩罚条件也影响低分且容易项目的学习效率。有趣的是,奖励和惩罚虽然对学习策略产生影响,却对学习绩效影响不显著,这表明在不同的学习条件下,不同的学习策略可以获得相似的学习成绩。     

团体心理治疗中凝聚力的概念及测量研究述评

团体心理治疗中的凝聚力最初多被定义为人际信任、吸引和卷入,随着研究的深入,凝聚力的概念逐渐向多维的方向发展。对凝聚力的测量主要有MacKenzie的团体氛围量表、Lese等的治疗因素-凝聚力分量表及Piper的凝聚力量表等。目前团体心理治疗领域的研究对凝聚力的认识缺乏一致性。从凝聚力的概念建构着手,探索团体心理治疗过程,开发评估工具,构建系统的理论和模型,是值得国内研究者关注的方向。     

白血病诱导分化治疗中的生态自然观

诱导分化是一种治疗白血病的新方法,它通过促使分化不完全的肿瘤细胞分化成熟,使恶性转为良性.临床应用全反式维甲酸(ATRA)和三氧化二砷(As2O3)诱导急性早幼粒细胞性白血病取得了较高的完全缓解率,毒副作用也较低.诱导分化治疗策略突破了将杀灭肿瘤细胞作为治疗肿瘤的惟一方法的思维局限,谋求在与白血病细胞的和谐中获得人类的健康,是生态自然观应用于医疗实践的成功范例.

How expected evaluation influences creativity: Regulatory focus as moderator

Two studies investigated the effect of expected evaluation and regulatory focus on individuals’ creative performance. In both studies, first, the type of evaluation (informational versus controlling) was manipulated, and then regulatory focus was measured as an individual difference (in Study 1) or induced as a state using a pencil-and-paper maze task (in Study 2). Results provided evidence that participants who expect an informational evaluation were more likely to adopt an eager strategy; whereas participants who expected a controlling evaluation were more likely to adopt a vigilant strategy. Furthermore, participants in promotion-informational and prevention-controlling groups (regulatory fit conditions) performed more creatively than those in promotion-controlling and prevention-informational groups (regulatory non-fit conditions). In sum, the present findings contribute to a better understanding of how external evaluations and basic motivational orientations influence creative performance.     

On Enhancing the Cross‐Cultural Comparability of Likert‐Scale Personality and Value Measures: A Comparison of Common Procedures

This study aims to evaluate a number of procedures that have been proposed to enhance cross‐cultural comparability of personality and value data. A priori procedures (anchoring vignettes and direct measures of response styles (i.e. acquiescence, extremity, midpoint responding, and social desirability), a posteriori procedures focusing on data transformations prior to analysis (ipsatization and item parcelling), and two data modelling procedures (treating data as continuous vs as ordered categories) were compared using data collected from university students in 16 countries. We found that (i) anchoring vignettes showed lack of invariance, so they were not bias‐free; (ii) anchoring vignettes showed higher internal consistencies than raw scores where all other correction procedures, notably ipsatization, showed lower internal consistencies; (iii) in measurement invariance testing, no procedure yielded scalar invariance; anchoring vignettes and item parcelling slightly improved comparability, response style correction did not affect it, and ipsatization resulted in lower comparability; (iv) treating Likert‐scale data as categorical resulted in higher levels of comparability; (v) factor scores of scales extracted from different procedures showed similar correlational patterning; and (vi) response style correction was the only procedure that suggested improvement in external validity of country‐level conscientiousness. We conclude that, although no procedure resolves all comparability issues, anchoring vignettes, parcelling, and treating data as ordered categories seem promising to alleviate incomparability. We advise caution in uncritically applying any of these procedures. Copyright © 2017 European Association of Personality Psychology     

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.
