表面内容不同方面相似性对样例迁移的影响

应用题表面内容分离为表面概貌和对象对应后,还可以进行再分解。本实验将表面概貌分解为具体属性和问题形式,将对象对应分解表述顺序对应和具体对象对应,研究结果表明,表面内容不同方面的相似性对原理运用有不同的影响。     

Attitudes to Marriage and Sexual Behaviors: A Survey of Gender and Culture Differences in China and United Kingdom

This paper reports a survey carried out among 505 university students in China and 338 students in the United Kingdom. The survey included questions on attitudes toward mate-selection preferences, marriage, and sexual behavior. The findings show that traditional values in mate-selection preferences persist more in China than in the United Kingdom and indicate that, despite a profound social revolution over the last two decades, a relatively conservative sexual culture still exists in China today. Traditional morality and attitudes prevail especially among women. Gender and culture differences are discussed.     

中文词汇切分对眼动数据的影响

该研究使用眼动研究中的“边界”技术范式,材料中的关键词为前两个字为双字词的三字词,如“服务员”,和非三字词,如“服务体”,考察可能存在的中文词汇切分策略对眼动时间指标的影响。实验使用2×2被试内设计,第一个因素是三字词的词频：高频和低频,第二个因素为不同词频条件下的非三字词基线。实验结果是三字词预视条件下的注视时间短于非三字词预视条件下的注视时间。结果表明自然阅读中的词汇切分策略确实存在,并且可以在眼动的时间指标上表现出来,结果还暗示在词汇切分过程中,读者在心理词典中对三字词的搜索是必需的过程。     

汉语转折复句的命题表征项目互换效应研究

采用句子一图画验证任务(sentence-picture verification task)探讨了汉语转折复句的命题表征项目互换效应。结果表明,汉语倒装转折复句的项目表达顺序为“(但是)B→虽然A”,命题表征中项目存在着互换的倾向,所形成的命题表征为“虽然A→但是B”。本研究结果初步表明,读者理解汉语转折复句可能是一个按照“虽然A(事实让步)→但是B(转折)”固定方向进行系列认知加工的过程。     

Imagery and rehearsal as study strategies for written or orally presented passages

In the present research, we studied the influence of text presentation modality on recall under imagery, rehearsal, and no strategy instructions. It was hypothesized that imagery is a more effective recall strategy for an oral presentation and rehearsal for a written presentation, and that imagery and rehearsal are effective study strategies. One hundred twenty participants participated, 80 of whom were trained in the use of imagery or rehearsal in the study of passages and 40 of whom made up the control group. A text was presented orally or in writing; the trained participants were to memorize it using the strategy taught, and the participants in the control group were to memorize it using a freely chosen strategy. They were then asked for free written recall. The results confirmed that the participants using imagery recalled the oral presentation better than the written one, and those using rehearsal recalled the written presentation better than the oral one. The discussion focuses on a selective-interference explanation of the presentation modality effects. Practical suggestions are given, and implications for future research are discussed.     

概念及概念结构研究新进展

近来有关归类和概念结构的研究与理论出现了两个方面的转变。第一个方面是从概念定义属性的假设 (经典观 )到概念表征属性的观点 (概率观 ) ;第二个方面是从概念以相似性组织的观点到概念围绕理论而组织的观点。本文综合概述了基于相似性和理论驱动的归类理论。     

表面概貌对原理运用的影响的实验研究

探讨样例与作业问题的表面概貌相似性对原理运用的影响作用。实验１扩大了Ｒｏｓｓ的研究材料中样例与测题表面概貌方面的差异程度,探讨两者的表面概貌相似性对原理运用的影响。实验２探讨样例与测题在表面概貌的事件类型方面发生改变的条件下,两者的表面概貌相似性对原理运用的影响。实验３探讨在样例与测题表面概貌有两个级别差异的条件下,两者的表面概貌相似性对原理运用的影响。３个实验均采用被试内设计,要求被试学习原理及样例后完成与样例的表面概貌有不同相似关系的测题。结果表明：（１）样例与问题的表面概貌对原理运用有影响,当两者表面概貌发生较大的变化尤其是在表面概貌的事件类型方面发生变化时,其表面概貌相似性对原理运用的影响就会明显地表现出来;（２）样例与问题的表面概貌对原理运用的影响作用,受到两者对象对应性质的制约,当对象对应相似时,其表面概貌相似就会促进解答测题时运用原理,而当两者的对象对应相反时,其表面概貌相似就会对原理运用产生干扰作用。据此可以认为,样例与作业问题表面概貌的相似性,不仅会影响原理的通达,而且也会影响原理的运用。Ｒｏｓｓ关于表面概貌相似与否不影响原理运用的结论应该予以修正。     

A multiplex view of leadership structure in management teams

In the hope of complementing the structural perspective in upper echelon research and advancing a fine-grained understanding of dyadic leadership influence in management teams, the current study combines two types of intrateam structures—leadership network and friendship network—to create a multidimensional conceptualization of leadership structure in management teams. Specifically, we propose that management teams with a denser singular leadership network (i.e., a network consisting of many leadership ties that are not coupled with friendship ties) should have lower management team cohesion, which subsequently renders worse business unit performance. To contrast, management teams with a denser multiplex network (i.e., a network consisting of many leadership ties that are coupled with friendship ties) should have higher management team cohesion, which subsequently renders better business unit performance. Guided by structural contingency perspective, we further propose that management team task interdependence will strengthen team cohesion's positive impact on business unit performance. To test the hypothesized model, we collected team-level social network data and multiple-wave survey data from 697 managers nested in 148 hotels (i.e., 148 management teams) owned by a large hospitality company. We also obtained objective performance data for each hotel (i.e., occupancy percentage rate and revenue per available room per day) as the criterion measure. The data supported our hypotheses. The theoretical and practical implications of our findings are discussed.
