大学生的性格优势及与主观幸福感的关系

性格优势与主观幸福感是积极心理学的两大核心研究领域,其中,关于性格优势的"价值实践分类体系"被认为是积极心理学发展至今最具影响的成就之一。研究招募115名在校大学生(69女,46男),分别完成优势价值实践调查、牛津幸福体验问卷,以及生活满意度量表。研究发现:(1)在24种优势中,大学生的五大"显著优势"依次为爱与被爱、正直诚实、感恩感激、美的领悟、善良慷慨;(2)希望乐观、爱与被爱、社交智慧、洞察悟性等性格优势与主观幸福感密切相关;(3)希望乐观、爱与被爱、谨慎审慎、洞察悟性对幸福体验的回归方程拟合程度最优,而希望乐观、宽容宽恕、社交智慧、创造才能对生活满意度的回归方程拟合程度最优。     

The modulation of stimulus structure on visual field asymmetry effects: The case of Chinese character recognition

Recent research suggests that visual field (VF) asymmetry effects in visual recognition may be influenced by information distribution within the stimuli for the recognition task in addition to hemispheric processing differences: Stimuli with more information on the left have a right VF (RVF) advantage because the left part is closer to the centre, where the highest visual acuity is obtained. It remains unclear whether visual complexity distribution of the stimuli also has similar modulation effects. Here we used Chinese characters with contrasting structures—left-heavy, symmetric, and right-heavy, in terms of either visual complexity of components or information distribution defined by location of the phonetic component—and examined participants' naming performance. We found that left-heavy characters had the largest RVF advantage, followed by symmetric and right-heavy characters; this effect was only observed in characters that contrasted in information distribution, in which information for pronunciation was skewed to the phonetic component, but not in those that contrasted only in visual complexity distribution and had no phonetic component. This result provides strong evidence for the influence of information distribution within the stimuli on VF asymmetry effects; in contrast, visual complexity distribution within the stimuli does not have similar modulation effects.     

BUILDING CHARACTER: A LEADERSHIP ESSENTIAL

Character is an increasingly important topic of discourse and analysis, however, much of the research remains problematic and conceptual. Even less evidence exists of the nature of the relationship between character and leadership. This study examined self-reported character and associated demographic correlates among a sample of 238 Australian business leaders. Exploratory factor analysis identified three dimensions of character consistent with theory. These dimensions were examined in relation to demographic variables. After controlling for social desirability bias, few statistically significant demographic differences were found. Further research is recommended to validate the model of character developed in our paper.

Institutional culture and individual behavior: Creating an ethical environment

Much of the work in professional ethics sees ethical problems as resulting from ethical ignorance, ethical failure or evil intent. While this approach gets at real and valid concerns, it does not capture the whole story because it does not take into account the underlying professional or institutional culture in which moral decision making is imbedded. My argument in this paper is that this culture plays a powerful and sometimes determinant role in establishing the nature of the ethical debate; i.e., it helps to define what are viable action options, what is the organization’s genuine mission, and what behaviors will be rewarded or criticized. Given these conclusions, I also argue that consulting ethicists need more than an understanding of ethics theory, concepts and principles; they also need a sufficiently rich understanding of organizational culture and a willingness and an ability to critique that culture. An earlier version of this paper was presented at the “Ethics and Social Responsibility in Engineering and Technology” meeting, New Orleans, 2003.     

结构对称性汉字视觉识别特点的实验研究

用命名作业通过二个实验考察了结构对称性汉字的视觉识别特点,结果表明,汉字识别具有显著的结构对称性效应,识别结构对称性汉字的加工明显快于非对称性汉字,对称性效应与字频效应,笔画效应具有显著的交互作用,进一步的简单效应的分析表明,这种结构对称性效应在低频字中起作用,而在高频字中不起显著作用;在多笔画字中起作用,而在少毛画字中不起显著作用,这表明,对称性汉字中的具有冗余信息的格式塔部件促进地识别汉字的加

大脑半球损害病人的汉字抄写研究

对３７例左、右半球病变者进行汉字抄写等测查。结果发现：１．大脑半球病变影响汉字抄写,但左和右半球病变者、皮层和皮层下病变者、失语和非失语病人的汉字抄写成绩无明显差异;２．无论有无失语,抄写与听写都无相关;与画图的关系取决于文化背景,即文化水平低者（无读写能力）汉字抄写与临摹画图高度相关,并受半测空间疏忽影响,而有读写能力者汉字抄写不受以上因素影响。由此推测：不同的汉字书写方式有着不同的神经机制;无汉字读写能力者抄写过程主要与右脑有关,而有读写能力者汉字抄写时双脑并用。     

SELECTIVE ASSOCIATIONS PRODUCED SOLELY WITH APPETITIVE CONTINGENCIES: THE STIMULUS-REINFORCER INTERACTION REVISITED

In studies reporting stimulus-reinforcer interactions in traditional conditioning paradigms, when a tone-light compound was associated with food the light gained stimulus control, but when the compound was paired with shock avoidance the tone gained control. However, the physical nature of the reinforcerrelated events (food vs. shock) presented in the presence of the tone-light compound was always confounded with the conditioned hedonic value of the compound's presence relative to its absence. When the compound was paired with shock, its presence was negative relative to its absence (which was shock-free). In contrast, when the compound was paired with food, its presence was positive relative to its absence (which was food-free). The present experiment dealt with this confounding effect by conditioning a tone-light compound to be positive or negative, relative to its absence, solely with food reinforcement. One group of rats received food for responding in the presence of the tone-light compound and no food in its absence. The other group also responded in the presence of the compound, but received food only in its absence. These rats were trained on a chained schedule in which responding in the presence of the tone-light compound produced a terminal link signaled by the absence of the compound; responding ceased in the terminal link because it delayed food delivery. In a test session to assess stimulus control by the elements of the compound, tone and light were presented separately under extinction conditions. Rats that had been exposed to a positive correlation between food and the compound emitted almost double the responses in the presence of the light as in the presence of the tone. In comparison, rats that had been exposed to a negative correlation emitted only two thirds as many responses in the presence of the light as in the presence of the tone. Because this selective association was produced using only food, it appears that the contingencies under which a reinforcer is presented, rather than (or as well as) its physical properties, can generate the selective associations previously attributed to “stimulus-reinforcer interactions.” This could mean that regardless of the class of reinforcer that ultimately maintains responding (appetitive or aversive), the contingency-generated hedonic value of the compound stimulus may influence the dominant modality of stimulus control.     

词素位置概率在中文阅读中的作用：词汇判断和眼动研究

中文词切分的认知机制一直是心理语言学关注的焦点问题之一,研究发现中文读者可使用词素位置概率等语言学线索帮助词切分,而首、尾词素位置概率的重要程度以往研究观点并不一致。本研究通过词汇判断和眼动实验,考察中文读者对首、尾词素位置概率的利用情况。实验1a和1b采用词汇判断任务,考察在不同词频条件下词首与词尾词素位置概率对词汇识别的影响。在错误率和反应时指标上,高频词条件下词首与词尾词素位置概率效应不显著;低频词条件下词首词素位置概率效应显著,词尾词素位置概率效应不显著。实验2a和2b采用句子阅读任务,考察在自然阅读情境中被试对词素位置概率的运用。在凝视时间、回视路径时间和总注视时间指标上,低频词条件下词首词素位置概率效应显著,词尾词素位置概率效应不显著。高频词条件下词首与词尾词素位置概率效应均不显著。词汇判断和眼动证据共同表明,词素位置概率信息是中文读者重要的语言词切分线索,且与词尾词素位置概率相比,词首词素位置概率在词汇切分与识别过程中发挥的作用更大。同时,词素位置概率线索的运用会受到词频的影响,研究结果支持复合词加工的混合通达表征模型。
