方差分量估计是概化理论的必用技术,但受限于抽样,需要对其变异量进行探讨。采用Monte Carlo数据模拟技术,探讨非正态数据分布对四种方法估计概化理论方差分量变异量的影响。结果表明:(1)不同非正态数据分布下,各种估计方法的“性能”表现出差异性;(2)数据分布对方差分量变异量估计有影响,适合于非正态分布数据的方差分量变异量估计方法不一定适合于正态分布数据。  相似文献

Preschoolers were tested on a variety of oddity problems—that is, problems where one object in a set of four differed from the other three on one dimension. These dimensions consisted of colour, size, or form. The children were most accurate on size oddity problems in which one object was bigger than the others. They were almost as accurate on colour oddity problems. Form problems were next, and size oddity problems wherein the odd object was smaller than the other three objects were next. These decalages are interpretable in terms of relational complexity theory and executive function.  相似文献

Collective moral disengagement refers to shared group beliefs that morally justify negative actions. This study reports an initial validation of the newly developed Classroom Collective Moral Disengagement Scale (CCMDS) for adolescents. This self-report instrument assesses the degree to which mechanisms of moral disengagement are shared by students in their class. Data were collected from two samples of 486 and 654 adolescents attending middle and high schools in Italy. Through exploratory and confirmatory factor analyses the unidimensional structure of the scale was established. Multigroup analyses demonstrated configural, metric and scalar invariance of the model across age and gender groups. The final version of the scale consists of 17 items and it has good internal consistency and validity. It is concluded that the scale is a promising measure for research concerning group level morality.  相似文献

Research on “theory of mind” (TOM) suggests that a grasp of the mind develops universally and sequentially, but both these claims require testing in different cultural groups. Study 1, involving 72 preschoolers, showed the expected developmental transition on false belief tasks; 3 year olds were below statistical chance, while 4 year olds were at chance, representing a lag behind Western children. The same pattern of at chance (pretence, desire and belief) and below chance performance (false belief) was replicated in study 2 with 77 preschoolers (3–5 years) and corroborated the lag identified for some Asian countries. This deficient and varied timing of TOM performance is consistent with theories (social constructivist) supporting the role of social factors in TOM development. Moreover, significant inter-task correlations corroborate the need to broaden the research focus beyond false belief tasks.  相似文献

贿赂是指财物由行贿者向受贿者转移, 公共权力由受贿者向行贿者的暂时转移, 并涉及到为私利而滥用公共权力的过程。研究者认为集体主义是影响贿赂的文化心理根源, 而实证研究发现集体主义与贿赂的关系受到两个方面因素的影响。一方面贿赂的研究视角影响集体主义与贿赂的关系。研究一致证明集体主义促进贿赂行为意向。然而虽然大部分研究表明集体主义与贿赂感知和贿赂态度正相关, 但仍有少量不一致结果。另一方面集体主义类型也影响着集体主义和贿赂的关系。前人关于集体主义对贿赂的作用机制仍以理论探讨为主, 实证研究主要以道德卷入和计划行为理论为基础。未来可以从澄清不同贿赂研究视角的区别与联系、区分不同类型集体主义与贿赂的关系以及关注集体主义对贿赂的作用机制这三个角度进行深入探索。  相似文献

The objective of this study was to examine the effectiveness of a 12 week weight loss intervention within a commercial fitness centre on body weight, moderate to vigorous physical activity (MVPA), dietary intake, and behavioural regulations for exercise and healthy eating. Using a quasi-experimental design, the intervention group received weekly coaching sessions and bi-weekly seminars designed to increase MVPA and improve dietary intake. Outcome variables were assessed at three time points over a six month period. Results showed a significant interaction for body weight (p = .04) and dietary changes (p < .05) following the weight loss challenge but were not maintained across the six month period. Changes in behavioural regulations favoured the intervention condition. Results imply that a 12 week weight loss challenge within a commercial fitness centre may be effective at prompting short-term weight loss and support the internalization of behavioural regulations specific to healthy eating and exercise.  相似文献

In this paper, we study the connections between working memory capacity (WMC) and learning in the context of economic guessing games. We apply a generalized version of reinforcement learning, popularly known as the experience-weighted attraction (EWA) learning model, which has a connection to specific cognitive constructs, such as memory decay, the depreciation of past experience, counterfactual thinking, and choice intensity. Through the estimates of the model, we examine behavioral differences among individuals due to different levels of WMC. In accordance with ‘Miller’s magic number’, which is the constraint of working memory capacity, we consider two different sizes (granularities) of strategy space: one is larger (finer) and one is smaller (coarser). We find that constraining the EWA models by using levels (granules) within the limits of working memory allows for a better characterization of the data based on individual differences in WMC. Using this level-reinforcement version of EWA learning, also referred to as the EWA rule learning model, we find that working memory capacity can significantly affect learning behavior. Our likelihood ratio test rejects the null that subjects with high WMC and subjects with low WMC follow the same EWA learning model. In addition, the parameter corresponding to ‘counterfactual thinking ability’ is found to be reduced when working memory capacity is low.  相似文献

Sport consumerism is a burgeoning field of practice and serves both the utilitarian and behaviouristic goals. The utilitarian aspects are aligned to derivatives of value generated through the sport consumption effort. Behaviourism in the consumer context suggests a communal narrative, informed through observable actions which, in totality, construe social phenomena. This article applied social exchange theory to understand the utilitarian and behavioural functions sub-served by sport consumer psychology in the African context. An evaluation of literature from regional studies is made and the theory is explored with the view of putting forward research themes for the future.  相似文献

This study aimed to evaluate the latent structure of the Prospective and Retrospective Memory Questionnaire (PRMQ) and to estimate the reliability and validity of scores from the measure in a Nigerian adult population (N = 758; age range = 18 - 63 years; females = 52.24%). Respondents also completed the Cognitive Failures Questionnaire (CFQ). The data were analysed utilising confirmatory factor analysis (CFA). The results suggest the PRMQ to have a tripartite structure characterised by the following features: general memory, plus eight prospective and eight retrospective memory items. Scores from the PRMQ had evidence of convergent validity with the CFQ. The reliability of scores from the PRMQ was of acceptable magnitude for the research purposes investigated in the study.  相似文献

BackgroundHealth inequalities are to a substantial degree due to socioeconomic status (SES) related differences in health behaviors such as physical activity. However, little is known about the role SES plays in the self-regulation of physical activity.PurposeThis systematic review with meta-analysis examines whether a comprehensive set of indicators of SES (income, education, occupational status) impacts on the behavioral self-regulation by moderating the relationships between social cognitions in the Theory of Planned Behavior (TPB) and physical activity.MethodsA systematic literature search identified 99 studies from 88 articles that provided information on sample SES and correlations between TPB variables and physical activity. Random-effects meta-analyses were used to pool correlations corrected for sampling and measurement error. Random-effects meta-regression was used to examine moderating effects of study-level SES on these correlations.ResultsEducation moderated the relationship between intentions and physical activity, such that studies with better educated samples reported stronger intention-physical activity relationships.ConclusionsThese results suggest that education might play a major role in the self-regulation of physical activity, with better educated samples more likely to translate intentions into behavior. This can both help to explain heterogeneity in the relation between intentions and physical activity as well as support the development of more effective interventions targeting intentions and physical activity.  相似文献
