Effects of a meaningful, a discriminative, and a meaningless stimulus on equivalence class formation

Thirty college students attempted to form three 3-node 5-member equivalence classes under the simultaneous protocol. After concurrent training of AB, BC, CD, and DE relations, all probes used to assess the emergence of symmetrical, transitive, and equivalence relations were presented for two test blocks. When the A-E stimuli were all abstract shapes, none of 10 participants formed classes. When the A, B, D, and E stimuli were abstract shapes and the C stimuli were meaningful pictures, 8 of 10 participants formed classes. This high yield may reflect the expansion of existing classes that consist of the associates of the meaningful stimuli, rather than the formation of the ABCDE classes, per se. When the A-E stimuli were abstract shapes and the C stimuli became S(D)s prior to class formation, 5 out of 10 participants formed classes. Thus, the discriminative functions served by the meaningful stimuli can account for some of the enhancement of class formation produced by the inclusion of a meaningful stimulus as a class member. A sorting task, which provided a secondary measure of class formation, indicated the formation of all three classes when the emergent relations probes indicated the same outcome. In contrast, the sorting test indicated "partial" class formation when the emergent relations test indicated no class formation. Finally, the effects of nodal distance on the relatedness of stimuli in the equivalence classes were not influenced by the functions served by the C stimuli in the equivalence classes.     

Psychopathic personality traits in relational aggression among young adults

Psychopathy is a robust predictor of overt physical aggression that may also be relevant to relational aggression (RA). This study was conducted to investigate the utility of psychopathic personality traits in the prediction of RA in a sample of 291 college students. Hierarchical multiple regression analyses indicated that both primary and secondary psychopathic traits explained additional variance in general/peer and romantic RA beyond physical aggressiveness. Consistent with previous research, no gender differences were found on either form of RA, challenging the popular stereotype of RA as a female behavior. Moreover, psychopathic traits were not differentially predictive of RA by gender or level of physical aggressiveness. Implications of these findings for research and clinical practice are discussed.     

累积生态风险与高职生学习倦怠：消极自我图式和网络成瘾的中介作用

采用累积生态风险问卷、消极自我图式问卷、网络成瘾问卷以及学习倦怠问卷对湖南省4所高职院校的664名高职生进行调查,考察累积生态风险与高职生学习倦怠的关系以及消极自我图式、网络成瘾的中介作用。结果发现:(1)高职生累积生态风险、消极自我图式、网络成瘾和学习倦怠均呈显著正相关;(2)高职生累积生态风险对学习倦怠的直接效应和间接效应均显著。间接效应包括了三条路径:通过消极自我图式的中介作用、通过网络成瘾的中介作用以及通过消极自我图式和网络成瘾的链式中介作用。这一结论有助于理解累积生态风险对学习倦怠的作用机制,为降低高职生的学习倦怠提供参考建议。     

想象性群际接触对合作行为的影响：内隐性别偏见的中介作用

为考察想象性群际接触对内隐性别偏见与合作行为的影响,采用单类内隐联想测验（SC-IAT）和三种合作范式进行了两个实验。结果发现：与对照组相比,（1）积极想象性接触能显著降低不同性别个体对异性的内隐性别偏见。（2）积极想象性接触仅能显著增加个体在囚徒困境中的合作行为,内隐性别偏见起部分中介作用。结果表明,积极想象性接触既能减少个体对异性群体的内隐性别偏见,并可进一步促进两人情境中与异性间的合作行为。     

The function of wisdom dimensions in ego‐identity development among Chinese university students

This study investigates the relationship between wisdom and ego‐identity among university students in China. Using Marcia's ego‐identity statuses and Ardelt's wisdom dimensions as the theoretical and conceptual framework, the study investigates 356 university students in China. After exploratory and confirmatory factor analyses, four factors from wisdom and five factors from ego‐identity were retrieved. A structural equation model was then conducted to analyse the relationships. The findings were: (1) among wisdom dimensions, cognitive, and reflective wisdom, especially perspective‐taking best predicted achievement, (2) all three dimensions of wisdom predicted moratorium, but reflective wisdom was the most pronounced predictor, (3) all three dimensions of wisdom predicted diffusion, but resentment items from reflective wisdom were the most pronounced predictors, and (4) gender was a significant predictor of ego‐identity achievement and diffusion. These findings suggest that efforts to build reflective wisdom might contribute to healthier ego‐identity formation.     

Unraveling Brain Functional Connectivity of encoding and retrieval in the context of education

Human memory is an enigmatic component of cognition which many researchers have attempted to comprehend. Accumulating studies on functional connectivity see brain as a complex dynamic unit with positively and negatively correlated networks in perfect coherence during a task. We aimed to examine coherence of network connectivity during visual memory encoding and retrieval in the context of education. School Educated (SE) and College Educated (CE) healthy volunteers (n = 60) were recruited and assessed for visual encoding and retrieval. Functional connectivity using seed to voxel based connectivity analysis of the posterior cingulate cortex (PCC) was evaluated. We noticed that there were reciprocal dynamic changes in both dorsolateral prefrontal cortex (DLPFC) region and PCC regions during working memory encoding and retrieval. In agreement with the previous studies, there were more positively correlated regions during retrieval compared to encoding. The default mode network (DMN) networks showed greater negative correlations during more attentive task of visual encoding. In tune with the recent studies on cognitive reserve we also found that number of years of education was a significant factor influencing working memory connectivity. SE had higher positive correlation to DLPFC region and lower negative correlation to DMN in comparison with CE during encoding and retrieval.     

超文本环境下大学生自我调节学习的特征

随着计算机网络技术的出现和普及,超文本也开始逐渐成为人们阅读和学习的主要信息呈现方式。为了深入地了解大学生在超文本环境下的自我调节学习特点,采用口语报告的方法,使用修订的自我调节学习的过程模型对75名大学生进行研究。结果表明,超文本学习环境中大学生自我调节学习表现出对目标、区分有效信息、时间分配、选择新的信息资源、对情境的利用等过程的使用偏好。优生在目标、学习判断、略读过程上的使用率显著高于差生,差生在求助和无效搜索过程上的使用率显著高于优生。超文本学习环境下大学生自我调节学习存在着过程使用偏好,优差生在自我调节过程中表现出不同的使用偏好。

大学生自尊与网络过激行为的关系:社交焦虑和双自我意识的作用

本研究探讨了自尊与网络过激行为的关系,以391名大学生为被试,采用问卷法考察了社交焦虑在自尊与网络过激行为关系中的中介作用,以及该过程是否受到公我意识、私我意识水平的调节。结果发现：（1）在控制了性别、年龄后,自尊对网络过激行为具有负向预测作用;（2）社交焦虑在自尊和网络过激行为间起部分中介作用;（3）公我意识调节自尊对网络过激行为的直接作用。相对于公我意识水平高的大学生,直接效应对公我意识水平低的大学生更显著;（4）自尊对社交焦虑的作用还受到个体私我意识的调节,相对于私我意识水平低的大学生,间接效应对于私我意识水平高的大学生更显著。
