声旁与笔画省略方式对形声字识别的影响

本研究通过两个实验,考察笔画省略方式和声旁对形声字识别的影响。实验一采用命名任务考察了声旁和三种笔画省略方式（省前、略后、不省）对左右结构形声字识别的影响。结果表明存在笔画顺序效应和声旁位置效应,并发现略后的笔画中有声旁,笔画顺序效应会消失。这说明声旁的作用抵消了笔画顺序效应,体现了声旁在形声字识别中的重要作用;实验二在实验一的基础上,采用上下结构的形声字,实验结果表现出了相同的趋势,且更加显著。     

成败反馈对大学生核心自我评价的影响：任务重要性、外向性的调节作用

该研究以247名大学生为被试,采用2（反馈类型：成功、失败）×2（任务重要性：重要任务、不重要任务）×2（外向性：内向、外向）组间设计探讨成败反馈对大学生核心自我评价的影响,以及任务重要性和外向性在其中的调节作用。结果表明：（1）反馈类型、任务重要性和外向性对核心自我评价变化的主效应及三者的交互作用效应均显著。（2）成败反馈与任务重要性对核心自我评价变化存在显著的交互作用;简单效应分析表明,在失败反馈条件下,执行重要任务被试核心自我评价的下降幅度显著大于执行不重要任务被试核心自我评价的下降幅度。（3）成败反馈与外向性对核心自我评价变化存在显著的交互作用;简单效应分析显示,在失败反馈条件下,外向被试核心自我评价的下降幅度显著小于内向被试。（4）在失败反馈条件下,任务重要性和外向性对核心自我评价的变化存在交互作用。     

Prediction of goal orientation and perceived competence on intensity and direction of precompetitive anxiety among adolescent handball players

This study explored the main and interactive effects of goal orientations and perceived competence on intensity and direction of the symptoms of precompetitive cognitive and somatic anxiety. 109 handball players from 16 high school teams (M = 16.2 yr., SD = 1.5) participated. All were asked to complete the Task and Ego Orientation in Sport Questionnaire, Perceived Competence Questionnaire, and a modified version of the Competitive State Anxiety Inventory-2. Using separated multiple hierarchical regression analyses, direction of the symptoms of precompetitive somatic anxiety was predicted by perceived competence and interaction of ego orientation x perceived competence. Perceived competence and the interaction of ego orientation x task orientation x perceived competence were significant predictors of direction of the symptoms of precompetitive cognitive anxiety. The results suggest that perceptions of competence and task orientation moderate the relationship between ego orientation and direction of the symptoms of precompetitive anxiety.     

社会认知复杂性的量化指标及其关系

在Kelly个人构念理论的基础上,Bieri提出用构念的分化程度衡量个体社会认知复杂性的思路,并具体用从不同构念上评价每个角色时评分的匹配个数作为复杂性的最化指标。此后,研究者从不同分析思路提出了一系列新的复杂性指标,如根据对构念的相关分析所得组内相关、RMS、SMC等,基于因素分析所得第一因素解释率、主要因素个数及其解释率等,冲突分析所得整体冲突百分比,此外还有MPP、LPP、ASO等各种Fiedler分数。本研究以402名初中一二年级青少年为被试。采用库格测验收集数据,以Gridstat4．0、Excel、SPSSl0．0等软件统计数据,分析了上述各种复杂性指标的内在关联,为同类研究选择使用这些指标提供了依据。     

先天性色觉异常的特性及检查方法

本文简单介绍了各种先天性色觉异常的特性及常用的色觉检查方法。不同类型的先天性色觉异常在颜色匹配、光谱感受性、色差辨别等方面均表现出不同的特点,色觉检查方法就是在这些特点的基础上,根据异常者的某一色觉缺陷设计的。常用的检查方法有假同色图测验,色相排列测验和色盲镜等。一般来说,不同的检查方法各有所长,并应用于临床的不同阶段     

Occupational stress in clinical nurses

The present study was based on an integrative work stress model proposed by Cooper and his associates (Cooper et al., 1988), which focused on stress perception and outcomes, as well as potential moderating variables such as personality and coping efforts. Specifically, this article examines occupational stress in clinical nurses who worked in various hospitals in southern Taiwan. When compared with Chinese industrial white and blue-collar workers, nurses experienced higher work stress, more physical and mental ill-health, lower job satisfaction, and also made more efforts to cope with work stress. There were also some interesting differences in types of stressors experienced by nurses and industrial workers.     

Self-Explanations: How Students Study and Use Examples in Learning to Solve Problems

The present paper analyzes the self-generated explanations (from talk-aloud protocols) that “Good” and “Poor” students produce while studying worked-out examples of mechanics problems, and their subsequent reliance on examples during problem solving. We find that “Good” students learn with understanding: They generate many explanations which refine and expand the conditions for the action parts of the example solutions, and relate these actions to principles in the text. These self-explanations are guided by accurate monitoring of their own understanding and misunderstanding. Such learning results in example-independent knowledge and in a better understanding of the principles presented in the text. “Poor” students do not generate sufficient self-explanations, monitor their learning inaccurately, and subsequently rely heavily on examples. We then discuss the role of self-explanations in facilitating problem solving, as well as the adequacy of current AI models of explanation-based learning to account for these psychological findings.     

The Joint Moderating Effects of Activated Negative Moods and Group Voice Climate on the Relationship between Power Distance Orientation and Employee Voice Behavior

Employees inherently have concerns about the consequences of speaking up, and this is particularly notable for employees with high power distance orientation (PDO). Drawing on ideas from the dual‐pathway model of mood and social information processing theory, we propose that activated negative mood and group voice climate can synergistically facilitate high‐PDO employees' voice behaviors. Using a sample from 305 real‐estate sales agents in 66 work groups in Taiwan, we examined the joint moderating effects of activated negative mood and group voice climate on employees' two forms of voice behavior. Our results show that PDO had a negative relationship with promotive voice but did not have a significant relationship with prohibitive voice. Nevertheless, our results show that in the situation where both activated negative mood and group voice climate were high, PDO no longer had a negative relationship with promotive voice, and even had a positive relationship with prohibitive voice. The findings of this study provide theoretical insights for the voice literature and offer practical suggestions for facilitating opinion expression in organisations.
