This article compares a variety of imputation strategies for ordinal missing data on Likert scale variables (number of categories = 2, 3, 5, or 7) in recovering reliability coefficients, mean scale scores, and regression coefficients of predicting one scale score from another. The examined strategies include imputing using normal data models with naïve rounding/without rounding, using latent variable models, and using categorical data models such as discriminant analysis and binary logistic regression (for dichotomous data only), multinomial and proportional odds logistic regression (for polytomous data only). The result suggests that both the normal model approach without rounding and the latent variable model approach perform well for either dichotomous or polytomous data regardless of sample size, missing data proportion, and asymmetry of item distributions. The discriminant analysis approach also performs well for dichotomous data. Naïvely rounding normal imputations or using logistic regression models to impute ordinal data are not recommended as they can potentially lead to substantial bias in all or some of the parameters. 相似文献

This study explored the relationships between psychological contract types and innovative behavior. We focused on the mediating effect of work engagement and the moderating effect of job resources (organizational and social resources). Participants were 267 dyads of research and development engineers and their supervisors from 30 high‐tech companies. Moderated path analysis was used to test the hypotheses. Findings showed that: (a) work engagement fully mediated the negative relationship between transactional contracts and innovative behavior; in addition, it also fully mediated the positive relationship between relational contracts and innovative behavior; and (b) job resources attenuated the former and strengthened the latter mediating effects. These findings contribute to understanding how, why, and when psychological contract types lead to innovative behavior via work engagement. 相似文献

采用父母教养方式问卷、佛洛斯特多维完美主义量表和一般拖延量表对315位大学生进行调查,建立父母教养方式、完美主义和拖延的结构方程模型,考察完美主义在父母教养方式与拖延之间的中介作用。结果发现:(1)消极的父母教养方式负向预测适应性完美主义,正向预测非适应性完美主义;(2)适应性完美主义负向预测拖延,非适应性完美主义正向预测拖延;(3)父母教养方式通过完美主义的中介作用影响拖延行为,非适应性完美主义者易拖延,适应性完美主义者则不易拖延。 相似文献

辩证情绪是指个体对同一刺激同时体验到积极和消极情绪的一种心理状态.为探索辩证思维和辩证情绪的因果关系,在研究1中首先收集和筛选了诱发辩证情绪的视频;在研究2中,选取219个被试,先通过思维启动改变被试的辩证思维程度,然后考察辩证思维程度的改变对随后诱发辩证情绪强度的影响.结果发现,思维启动(辩证思维和线性思维)引起的辩证思维程度的差异显著,辩证情绪诱发效果显著,辩证思维在启动类型和辩证情绪之间的中介作用显著.这揭示了辩证思维程度的改变确实引起随后诱发的辩证情绪强度的变化,即辩证思维和辩证情绪存在因果关系. 相似文献

为了解中小学生的生活满意度状况,课题组用中小学生的愉快心境来定义生活满意度,对我国10249名中小学生进行了调查。结果表明:85%的中小学生生活得很愉快或比较愉快,72.3%的中小学生有烦恼,经检验存在明显的年级、性别及城乡差异;中小学生最烦恼问题排在前三位的分别是学习紧张、父母期望值高、同学中没友谊;中小学生最烦恼问题与愉快心境相关的排序依次是:父母期望值高、学习紧张、家庭气氛紧张和同学中没友谊。 相似文献

学习判断是指对当前已经学习的项目在以后测验中成绩的预见性判断。本研究以小学五年级学生为被试,选取正向词对和反向词对为实验材料,考察不同回忆任务下小学生学习判断的准确性及偏差。研究发现,小学五年级学生的即时学习判断的准确性受到词对类型和回忆任务的影响:(1)小学生线索回忆任务下的学习判断中,正向词对的准确性较好,反向词对出现了高估,表现出了学习判断的预见偏差;(2)自由回忆任务下的学习判断中,两种词对都出现了显著的高估。研究结果丰富和细化了流畅性假说对学习判断加工机制的解释,并提出即时学习判断准确性的偏差是由于编码流畅性和提取流畅性的差异造成的。 相似文献

元认知监控包括自我监控和监控他人。本研究用两个实验分别探讨了小学低年级学生自我监控和监控他人之间的关系及其发展趋势。实验一采用100以内加减法的计算任务,来探讨小学低年级学生的自我监测和监测他人。实验二采用难度不同、分值不同的计算任务,来探讨学生的自我控制和控制他人。研究发现:第一,小学低年级学生的自我监测和监测他人都会以前期任务表现为依据,支持MPT假说。而且,自我监测和监测他人都在二年级表现出了明显的转化和提高。第二,小学低年级学生在监测他人时,逐渐由以自我信息为依据调整到以他人认知状态为依据。第三,元认知控制能力的发展落后于监测能力。二年级和三年级学生仍旧不能很合理地进行自我执行和计划他人。 相似文献

Background. Methods for teaching thinking may be described as out‐of‐context or infusion. Both approaches have potential to raise students’ general cognitive processing ability and so raise academic achievement, but each has disadvantages. Aims. To describe and evaluate a theory‐based learn to think (LTT) curriculum for primary school students, which draws on the strengths of both out‐of‐context and infusion approaches. Sample. One‐hundred and sixty‐six students in three classes of Grade 1 (6+ years old), Grade 2 (7+ years old), and Grade 3 (8+ years old) in a primary school in Shanxi province, China, randomly ascribed to experimental (90) and control (76) groups. Methods. All students were pre‐tested for non‐verbal intelligence and academic achievement. Experimental students followed the LTT curriculum (one activity every 2 weeks) for 4 school years. All were post‐tested on three occasions for thinking ability and four times for academic achievement. Results. Grade 1 and Grade 2 students showed effects of LTT from 1 year after their start and increasing: on thinking ability d= .78–1.45; on Chinese d= .68–1.07; on maths .58–.87. Grade 3 students showed effects from 6 months after their start: on thinking ability .90–1.37; Chinese .77–1.32; maths .65–1.29. The effects were concentrated in students in the middle band of initial ability. Conclusions. A curriculum for teaching thinking based on a structured theoretical model that combines elements of out‐of‐context and infusion methods has been shown to have long‐term far transfer effects on students’ thinking ability and academic achievement. More work is needed to meet the needs of a wider range of abilities. 相似文献
