In order for theology to have a cognitive dimension, it is necessary to have procedures for testing and critically evaluating theological models. We make use of certain features of scientific models to show how science has been able to move beyond the poles of foundationalism, represented by logical positivism, and antifoundationalism or relativism, represented by the sociologists of knowledge. These ideas are generalized to show that constructing and testing theological models similarly offers a means by which theology can move beyond confessionalism and postmodernism. Our starting point is Paul Tillich's concept of God as the ground of being and the different levels of consciousness and thinking that accompany his understanding of theology. The ontological argument of Anselm is shown to play a key role, not as a proof for the existence of God but as a means for testing theological models. An example of a theological model, drawn from the domain of philosophy of science, is presented to show how theological models are constructed and tested.  相似文献

与一阶因素模型相比,二阶因素模型具有较多优点,但二阶因素模型的测量等价性检验要更复杂,它需要依次进行七个不同水平的检验:形等价、一阶弱等价、二阶弱等价、一阶强等价、二阶强等价、二阶严等价和一阶严等价。低水平的等价性满足之后,才能进行更为严格的高一水平的等价性检验。运用均值和协方差结构(MACS)模型对大学生网络利他行为量表(IABSU)进行二阶因素模型的测量等价性检验,结果表明,IABSU具有跨地域的完全一阶、二阶严等价性。  相似文献

不同类型考试焦虑影响考试成绩的差异模式   总被引:6,自引:0,他引:6       下载免费PDF全文
调查了440名高中生,以不同类型考试焦虑为预测变量,以掌握目标、情绪性、应对反应、考试自我效能感、成绩-接近目标、成绩-回避目标、担忧、学习和考试技能、认知干扰为中介变量,期末数学考试成绩为最终结果变量,探讨不同类型考试焦虑影响考试成绩的模式。结果表明:不同类型考试焦虑具有不同的影响考试成绩的模式,即存在认知主导型模式(简称C模式)、生理唤醒主导型模式(简称P模式)、技能缺乏主导型模式(S模式)等三种不同的模式。担忧是C模式中的主要中介变量,P模式的主要特征是担忧对情绪性存在显著影响,S模式的特点是中介变量较少,学习和考试技能变量受考试焦虑和考试自我效能感双重影响并作用于考试成绩。  相似文献

The cognitive reflection test (CRT) is a short measure of a person's ability to resist intuitive response tendencies and to produce a normatively correct response, which is based on effortful reasoning. Although the CRT is a very popular measure, its psychometric properties have not been extensively investigated. A major limitation of the CRT is the difficulty of the items, which can lead to floor effects in populations other than highly educated adults. The present study aimed at investigating the psychometric properties of the CRT applying item response theory analyses (a two‐parameter logistic model) and at developing a new version of the scale (the CRT‐long), which is appropriate for participants with both lower and higher levels of cognitive reflection. The results demonstrated the good psychometric properties of the original, as well as the new scale. The validity of the new scale was also assessed by measuring correlations with various indicators of intelligence, numeracy, reasoning and decision‐making skills, and thinking dispositions. Moreover, we present evidence for the suitability of the new scale to be used with developmental samples. Finally, by comparing the performance of adolescents and young adults on the CRT and CRT‐long, we report the first investigation into the development of cognitive reflection.

在IRT框架下,建立了0-1评分方式下单维双参数Logistic多题多做(MAMI)测验模型。与Spray给出的一题多做(MASI)模型相比,MAMI不仅模型更加精致,而且扩展了适用范围,参数估计方法也不同,采用EM算法求取项目参数。Monte Carlo模拟结果显示,应用MAMI测验模型与测验题量作相应增加的作法相比,两者给出的能力估计精度相同,但MAMI模型给出的项目参数估计精度更高。如果将MAMI测验模型与被试人数相应增加的作法相比,项目参数的估计精度相同,但MAMI给出的能力参数估计精度更高。这个发现表明,在一定条件下若允许修改答案,并采用累加式记分方式,纵使题量不变,也可使能力估计的精度相当于题量增加一倍的估计精度,而项目参数估计精度也会提高。这些发现不仅对技能评价和认知能力评价有参考价值,而且对数据的处理方式也有参考价值  相似文献

拟合指数检验是评价结构方程模型(SEM)的重要环节。从协方差结构分析的角度将SEM与传统的回归模型比较,容易理解为什么SEM需要拟合指数。揭示了目前几种流行的拟合指数检验的实质:基于卡方的绝对拟合指数(如RMSEA)检验的实质是重新设定卡方检验的显著性水平(不同于通常的.05),相对拟合指数(如NNFI和CFI)检验的实质是基于虚模型设定均方(卡方与自由度之比)降低到的比例;在NNFI大于临界值后,报告和检验CFI是不必要的。根据研究结果提出了一些方便实用的拟合检验建议。  相似文献

From a study of methods of test construction – criterion-keying, item analytic, factor analytic and using item characteristic curves – it is shown that, in the sphere of personality tests, only factor analytic methods can ensure univariate measures. A further scrutiny of factor analytic methodology reveals various technical defects which have created a chaos of different findings and factors in personality inventories. It is finally demonstrated that rotation to simple structure yields reliable and replicable factors and that when this is done, four or five factors account for most of the variance in personality inventories. It is concluded that in occupational testing only tests measuring these factors, or primary factors clearly related to them, should be used.  相似文献

Increasing awareness of and the potentially concomitant increasing demand for cancer genetic services is driving the need to explore more efficient models of service delivery. The aims of this study were to determine which service delivery models are most commonly used by genetic counselors, assess how often they are used, compare the efficiency of each model as well as impact on access to services, and investigate the perceived benefits and barriers of each. Full members of the NSGC Familial Cancer Special Interest Group who subscribe to its listserv were invited to participate in a web-based survey. Eligible respondents were asked which of ten defined service delivery models they use and specific questions related to aspects of model use. One-hundred ninety-two of the approximately 450 members of the listserv responded (42.7 %); 177 (92.2 %) had provided clinical service in the last year and were eligible to complete all sections of the survey. The four direct care models most commonly used were the (traditional) face-to-face pre- and post-test model (92.2 %), the face-to-face pretest without face-to-face post-test model (86.5 %), the post-test counseling only for complex results model (36.2 %), and the post test counseling for all results model (18.3 %). Those using the face-to-face pretest only, post-test all, and post-test complex models reported seeing more new patients than when they used the traditional model and these differences were statistically significantly. There were no significant differences in appointment wait times or distances traveled by patients when comparing use of the traditional model to the other three models. Respondents recognize that a benefit of using alternative service delivery models is increased access to services; however, some are concerned that this may affect quality of care.  相似文献

风险决策是人类赖以生存和发展的重大决策。如何进行风险决策是人类不断认识和改造世界过程中遇到的未解之谜。主流风险理论认为, 风险决策是一个补偿性的、期望值最大化的过程; 而非主流的风险理论则认为, 风险决策是非补偿性的, 并不遵循期望法则所假设的加权求和等过程。这一谜团为何一直没有得以破解, 或许是因为我们未找到揭示其心理过程的令人信服的证据。近10年来, 我们针对风险决策过程, 借助行为实验、眼动记录法、事件相关电位、功能磁共振成像等技术, 系统探索风险决策的心理和神经机制, 为回答“风险决策是否遵循补偿性规则”这一问题提供了汇聚性证据。本文依据期望法则所假设的概率函数推导、加权过程、加权求和过程、总分最大化等步骤, 对这些研究进行梳理与回顾, 以期加深人们对风险决策机制的理解, 并为建立、健全与风险决策相关的政策、法律法规提供理论依据。  相似文献

Based upon findings from the organizational communication, management, and marketing literatures, this study evaluates three competing models describing sales force communication. The results of the analysis suggest that the theorized PEO (Sales Manager Communication Practices? Sales Force Communication Environment? Salesperson Communication and Job Outcomes) Model best accounts for the relations between sales manager communication practices and salesperson communication and job outcomes. Specifically, the PEO Model holds that sales manager communication practices are positively associated with salesperson perceptions of communication quality. Communication quality is positively associated with salesperson satisfaction with communication; salesperson communication satisfaction is positively related to salesperson's job satisfaction and organizational commitment. These results and their implications for developing an effective sales force communication environment are detailed.  相似文献

A multinormal partial credit model for factor analysis of polytomously scored items with ordered response categories is derived using an extension of the Dutch Identity (Holland in Psychometrika 55:5?C18, 1990). In the model, latent variables are assumed to have a multivariate normal distribution conditional on unweighted sums of item scores, which are sufficient statistics. Attention is paid to maximum likelihood estimation of item parameters, multivariate moments of latent variables, and person parameters. It is shown that the maximum likelihood estimates can be found without the use of numerical integration techniques. More general models are discussed which can be used for testing the model, and it is shown how models with different numbers of latent variables can be tested against each other. In addition, multi-group extensions are proposed, which can be used for testing both measurement invariance and latent population differences. Models and procedures discussed are demonstrated in an empirical data example.  相似文献

在众多的实验基础上, 研究者提出了分析视觉工作记忆的“容量有限模型”和“资源灵活分配模型”, 而两个模型在以下三方面存在着争论:(1)视觉工作记忆中保存的项目精度是否是固定的, (2)资源分配的模式是连续分配的还是以量子化模式分配的, (3)存储单元是以特征为单元还是以客体为单元。未来该领域的研究应加强对视觉工作记忆容量单元的探讨, 探索应用新的研究方法, 控制影响视觉工作记忆容量的空间因素等。  相似文献
