This investigation studied variability in visual thresholds for six subjects for 50 consecutive days. The results show the following:

1. Session-to-session variability agrees closely with the variability estimates made by Hecht and Zegers.

2. No periodic or cyclic trends appeared for the group or for any individual subject.

3. For all six subjects for the first 15 days of testing, a learning phenomenon was observed for the mean and standard-deviation data. There was a slow rise over the last 10 days of testing for the mean, but not for the standard-deviation data. (A discussion of the possible causes of the rise of the mean over the last 10 days suggested the influence of extraneous factors, such as boredom and fatigue.)

4. No effect of the menstrual cycle upon the threshold values was found.

This study assessed sex differences affecting the psychological wellbeing of Chinese adolescents. Various instruments were used to measure psychiatric symptoms and positive mental health. The results showed that female adolescents displayed significantly more psychiatric as well as somatic symptoms and scored lower on scales reflecting positive mental health. The findings are generally consistent with those found in the Western literature, but suggest that, in the Chinese culture, sex differences in mental health begin to appear in adolescents.  相似文献

This study addresses how moral judgment development, authenticity, and nonprejudice account for variance in scores pertaining to various motivational functions underlying volunteerism in order to clarify certain problems associated with previous research that has considered such relationships. In the study, 127 participants completed measurements that pertain to these constructs. Correlations revealed that moral judgment had a negligible relationship with both authenticity and nonprejudice, thereby affirming that the former construct is distinct from the latter two. Linear regression analyses supported that moral judgment development and nonprejudice provided the strongest contributions to the variance of the considered indices of volunteer motivation. The motivational function underlying volunteerism was also recognized as an important factor that pertains to the observed contributions of variance. Findings are discussed in concert with and compared to prior considerations of relationships between moral judgment development and considerations of the moral self. Implications where moral education is concerned are also considered.  相似文献

贪婪是人性的重要特点之一,也是哲学、经济学等领域经常讨论的话题.本文首先梳理了贪婪的概念,并将问题聚焦在对于物质的贪婪上.然后总结了贪婪的特点,并提出贪婪的定义.接着阐述了情境因素如何影响个体对贪婪的态度,以及贪婪动机如何影响自利行为.贪婪决策是个体决定是否做出贪婪行为的心理过程,受到自我意识和情绪的影响.贪婪决策过程模型整合了控制性、自动化两类加工方式,阐释了自利倾向与道德自觉相互作用的机制.本文对以上内容逐次进行讨论,并提出了未来研究的方向.  相似文献

情绪的动机维度模型认为, 积极情绪对认知加工的影响受其趋近动机强度的调节, 高、低趋近动机积极情绪对认知加工的影响不同。本研究运用情绪图片诱发被试高、低趋近动机积极情绪, 采用停止信号任务和任务转换作业考察了不同趋近动机强度积极情绪对认知控制的影响。结果发现:(1)与中性条件相比, 高趋近动机积极情绪促进了停止信号任务中Go任务和任务转换作业中重复任务的反应执行。(2)在停止信号任务中, 相对于中性条件, 低趋近动机积极情绪条件下的停止信号反应时显著缩短; 在任务转换作业中, 低趋近动机积极情绪条件下的反应时转换损失和错误率转换损失均显著降低, 而高趋近动机积极情绪条件下的反应时转换损失显著增加。因此, 积极情绪对认知控制的影响受其趋近动机强度的调节, 即低趋近动机积极情绪增强认知灵活性, 提高停止反应与任务转换的速度; 而高趋近动机积极情绪增强认知稳定性, 加快停止信号任务中Go任务和任务转换作业中重复任务的反应执行, 增加了反应时转换损失。  相似文献

In contrast with the view that intrinsic and extrinsic motivation are antagonistic, the view proposed in this article is that they are anchors of a continuous variable. According to the theory set out here, intrinsic motivation develops by means of internalization. This gives rise to four types of motivation: external, introjected, identified, and intrinsic. The main purpose of this study was to construct a scale to measure these four types of motivation for academic achievement and then to examine its validity. The Stepping Motivation Scale, created by the author, was administered to 483 junior high school students. Intercorrelations among the four subscales conformed to a simplex structure, and documented a continuum from extrinsic to intrinsic motivation. To clarify the distinction among the four types of motivation, relevant variables such as causal attributions and coping behaviors in failing situations, beliefs in links between extrinsic and intrinsic motivation, and teachers' evaluation of students' motivation were related to motivation types. A difference in motivational types was exhibited in the differential patterns of correlations.  相似文献

Two studies investigated the relationships between personality traits and aspects of job satisfaction. In Study 1, job applicants (n=250) completed the Eysenck Personality Profiler and the Work Values Questionnaire (WVQ), which requires respondents to rate various work-related facets according to the extent to which they contribute to their job satisfaction. These facets were combined into two composites (hygiene and motivator) based on previous research. The three personality superfactors accounted for a small percentage of the variance in importance ratings (about 5%). In Study 2, employees (n=82) completed a measure of the ‘Big Five’ personality traits and the Job Satisfaction Questionnaire (JSQ), which assesses both what respondents consider as important in their work environment as well as their satisfaction with their current job. Importance ratings were again combined into two composites while job satisfaction ratings were factor analyzed and three factors, differentiated along hygiene versus motivator lines, emerged. Personality traits again accounted for a small percentage of the total variance both in importance ratings and in levels of job satisfaction. It is concluded that personality does not have a strong or consistent influence either on what individuals perceive as important in their work environment or on their levels of job satisfaction.  相似文献

Changes in the nature of work and organisations have led to an increased need for self-directed career management (SDCM). However, there is no consensus in the literature of what constitutes SDCM and many related concepts have been proposed. Integrating previous research across different conceptualisations of SDCM, the article proposes four critical career resources which are essential for career development in the modern context: human capital resources, social resources, psychological resources and identity resources. Implications of this framework for counselling practice are presented.  相似文献

The present study explored the relations of emotional self-efficacy, career indecision and motivation in a sample of 200 French university students. Results from standard multiple regression analyses showed that emotional self-efficacy appeared the best predictor of intrinsic motivation toward education. The three dimensions of career indecision, as measured by CDDQ, do not revealed good predictors of intrinsic motivation. Concerning amotivation, inconsistent information (due to unreliable information, internal and external conflicts) is the best predictor of amotivation. Emotional self-efficacy also explains amotivation. The theoretical and practical implications of these findings are discussed.  相似文献

职业幸福感是国内外学者和管理实践者关注的重要问题, 本文综合资源保存理论、工作要求-资源模型和本土心理资本理论, 构建并检验了本土心理资本对职业幸福感的影响模型。研究一通过访谈、问卷调查等方法研制了信效度较好的问卷, 1566名教师的调查结果表明, 本土心理资本包含事务型心理资本(希望、乐观和坚韧)与人际型心理资本(自谦、感恩、利他、情商/情绪智力和信心/自我效能)。研究二使用2280名教师的有效数据, 通过控制了其他变量影响后进行结构方程建模及交叉验证分析, 结果表明:(1)职业幸福感(工作投入、工作倦怠、离职意愿和工作满意度)的积极情感体验(工作投入)与认知评价(工作满意度)存在增益螺旋过程; (2)心理资本通过能量补充和动机激发双过程促进职业幸福感; (3)人际型心理资本通过一级、二级能量补充与动机激发过程影响职业幸福感; 事务型心理资本也通过一级、二级动机激发过程影响职业幸福感, 但是只通过二级能量补充过程影响职业幸福感。在中国文化背景下, 人际型心理资本对职业幸福感的作用更大。  相似文献
