高师生心理健康教育实验研究

本文采用自然教学实验的研究方法,探讨心理健康教育对高师生健康信念、健康行为和健康水平的影响,以高师９５级大学三年级学生１２６个为实验组,进行５４个课时的心理健康课程教学,并以同校同级学生１０９个对照组。采用健康信念和健康行为调查表和Ｃａｗｔｅ健康量表,对实验组和控制组被试进行调查和测试。结果表明,心理健康教育不仅明显改善了高师生的健康信念和健康行为,而且提高了他们的身心健康水平。     

元认知的本质与要素

该文就元认知的本质和要素进行了探讨。文章首先对已有的相关观点进行了分析,在此基础上,将元认知的内涵界定为“个体对当前认知活动的认知调节”,并确定了元认知活动的三要素,即元认知技能、元认知知识、元认知体验,论述了每一要素在元认知活动中的作用,并以元认知三要素关系示意图描述了三者之间的关系。     

工业与组织心理学中的前瞻性人格

前瞻性人格是指个体不受情境阻力的制约,主动采取行动以改变其外部环境的倾向性。相关的实证研究发现前瞻性人格对个体工作结果、职业生涯结果、团队效能、领导效能、新进人员适应性以及创业等后果变量均具有一定的影响。该文对工业与组织心理学领域有关前瞻性人格的相关研究进行了较为全面的总结,并在此基础上指出未来的研究有必要加强组织层面因素在前瞻性人格与相关结果变量之间的调节作用等三方面问题的探讨     

Conversation Orientation and Cognitive Processes: A Comparison of U.S. Students in Initial Interaction With Native‐ Versus Nonnative‐Speaking Partners

The present study compares thought patterns, perceptions of interaction (perceived interaction smoothness and interaction involvement), and conversation orientation of U.S. students (N = 60) in dyadic interaction with a partner who is either another American or a non‐American nonnative speaker of English. As hypothesized, U.S. participants with nonnative‐speaking partners perceived interaction as more difficult, or less smooth, than did their counterparts with native‐speaking partners. U.S. participants with nonnative‐speaking partners also displayed different thought patterns, having more thoughts showing confusion, as well as more thoughts focused on the partner and less on the content of the ongoing conversation, than those with fellow native‐speaking partners. U.S. participants with a nonnative‐speaking partner also exhibited a different conversation orientation pattern, focusing more on understanding of the other's message, less on clarifying their own message, and less on displaying their own involvement. Specific thought categories and perceived interaction smoothness were correlated with conversation orientation indices for participants in interactions between native and nonnative speakers. Finally, interaction involvement was found to contribute most to variation in perceived interaction smoothness for both U.S. and non‐U.S. participants in interactions between native and nonnative speakers. Implications of the findings are discussed.     

消费行为研究中的联合分析法

联合分析(Conjoint Analysis)是一种定量的研究消费者选择偏好的方法。虽然从它诞生到现在只有40年的历史,但它对消费者行为学的影响很大,它的发展更是日新月异。文章首先介绍了联合分析的基本概念,然后重点阐述了联合分析的原理、步骤和发展历程,最后对联合分析的发展方向作了一个简要概括。     

Individual Goal Orientations,Team Empowerment,and Employee Creative Performance: A Case of Cross‐level Interactions

Intrigued by relationship between team motivational context and individual characteristics in the organizational reality, we developed and tested a cross‐level model to investigate the interactive effects of team empowerment and individual goal orientations on individual creative performance through the mediating mechanism of an individual's creative self‐efficacy. Using multi‐wave multi‐source data from 63 R&D teams in three IT companies, we found that (1) team empowerment, individual learning goal orientation, and individual performance orientation are all positively related to individual creative performance through mediation of creative self‐efficacy; (2) learning orientation and performance approach orientation could both supplement the effects of team empowerment on individual creative self‐efficacy. Our findings point to the importance of individual goal orientation in shaping the effects of team motivation climates and provide insights for both scholars and practitioners. The specific practical implications include but are not limited to (1) individuals with learning and performance approach orientations should be identified during hiring procedures given that they could still thrive in less empowered teams and maintain a relatively high level of creative self‐efficacy and creative outcomes; (2) managers should consider assigning employees who are more learning oriented to more empowering and open‐ended tasks in order to obtain better creative results.     

The Mediating Role of Creative Process Engagement in the Relationship between Shyness and Self‐Rated Creativity

Shyness has been found to have a negative impact on creativity. However, little attention has been given to the underlying process of the relationship between shyness and creativity. On the basis of literature, we hypothesize that shyness has an indirect impact on creativity through creative process engagement. Two studies were conducted on undergraduate students (Study 1) and working adults (Study 2) to test the hypothetical relationship. Analysis on participants self‐report showed that shyness was negatively associated with self‐reported creativity as well as creative process engagement. There was a positive relationship between creative process engagement and creativity. More importantly, mediation analysis supported that shyness was indirectly linked to creativity via creative process engagement. Specifically, shy people are found to be less involved in creativity‐relevant processes such as information searching and idea generation. The low level of creative process engagement, in turn, hinders their creativity. The findings not only lend support to the detrimental effect of shyness on creativity but also shed light on the underlying mechanism of the relationship.     

Comparing mand training and other instructional methods to teach a foreign language

The purpose of the current study was to examine the effects of mand, tact, and native‐to‐foreign (NFI) and foreign‐to‐native (FNI) intraverbal training on the acquisition of a foreign language. We used a multiple‐baseline design across participants with an embedded adapted alternating treatments design to compare the effects of mand training, tact training, NFI training, and FNI training on the acquisition rate of Chinese words in four typically developing adults. We also examined the emergence of untrained foreign language responses for each training condition. Data for 3 out of the 4 participants suggest that mand training was the most efficient training procedure with respect to acquisition rate. The greatest amount of emergent responding was observed for the mand and tact training conditions.     

时间洞察力对成瘾行为的影响及其机制

成瘾行为给个体和社会带来了严重的危害。对成瘾人群时间洞察力的研究成为探讨成瘾行为产生和发展的一个新的视角。过去消极、现在享乐和现在宿命时间洞察力取向的个体更可能出现成瘾行为, 而未来时间洞察力取向则是成瘾行为的一个保护性因素, 它不仅可以减少成瘾行为的发生, 也有利于成瘾行为的康复。从自我调节, 冲动性决策等行为机制和前额叶的神经机制方面可以帮助我们深入理解时间洞察力对成瘾行为的影响。未来研究可以进一步探讨不同成瘾行为者时间洞察力的一致性与特异性; 采用纵向研究方法探讨成瘾者时间洞察力的动态变化过程; 对成瘾者的洞察力进行干预, 增加成瘾者的未来时间洞察力, 减少其过去消极和现在时间洞察力取向来帮助成瘾者实现时间洞察力的平衡, 从而提高其戒断效果。
