This paper is a modification of Nicola Guarino and Christopher Welty's conception of the subsumption relation. Guarino and Welty require that that whether one property may subsume the other should depend on the modal metaproperties of those properties. I argue that the part of their account that concerns the metaproperty carrying a criterion of identity is essentially flawed. Subsequently, I propose to constrain the subsumption relation not, as Guarino and Welty require, by means of incompatible criteria of absolute identity but by means of incompatible criteria of relative identity. After discussing the benefits of applying relative identity in ontological investigations I provide a formal framework in which to prove a counterpart of the identity criteria constraint.This revised version was published online in October 2005 with corrections to the Cover Date.  相似文献

The aim of latent variable selection in multidimensional item response theory (MIRT) models is to identify latent traits probed by test items of a multidimensional test. In this paper the expectation model selection (EMS) algorithm proposed by Jiang et al. (2015) is applied to minimize the Bayesian information criterion (BIC) for latent variable selection in MIRT models with a known number of latent traits. Under mild assumptions, we prove the numerical convergence of the EMS algorithm for model selection by minimizing the BIC of observed data in the presence of missing data. For the identification of MIRT models, we assume that the variances of all latent traits are unity and each latent trait has an item that is only related to it. Under this identifiability assumption, the convergence of the EMS algorithm for latent variable selection in the multidimensional two-parameter logistic (M2PL) models can be verified. We give an efficient implementation of the EMS for the M2PL models. Simulation studies show that the EMS outperforms the EM-based L1 regularization in terms of correctly selected latent variables and computation time. The EMS algorithm is applied to a real data set related to the Eysenck Personality Questionnaire.  相似文献

Our goal was to develop a commensurate measure of personality‐based person‐organization fit and examine its criterion‐related validity for two retention‐related attitudes: job satisfaction and intention to stay. At T0, 637 employees completed our questionnaire. Two years later, at T1, 171 of the original respondents completed our questionnaire again. Results showed that the organizational personality perceptions are relatively stable. Polynomial regression analyses and surface plots revealed that job satisfaction and intention to stay are higher when there is perfect fit between the person and the organization compared to when the person and the organization differ in traits. However, in most cases, we found the work attitudes to be maximized when both the person and the organization score high on the personality traits.  相似文献

In recognition memory experiments participants must discriminate between old and new items, a judgment influenced by response bias. Research has shown substantial individual differences in the extent to which people will strategically adjust their response bias to diagnostic cues such as the prior probability of an old item. Despite this significant between subject variability, shifts in bias have been found to be relatively predictive within individuals across memory tests. Experiment 1 sought to determine whether this predictability extends beyond memory. Results revealed that the amount a subject shifted response bias in a recognition memory task was significantly predictive of shifting in a visual perception task, suggesting that shifting can generalise outside of a specific testing domain. Experiment 2 sought to determine how predictive shifting would be across two manipulations well known to induce shifts in bias: a probability manipulation and a response payoff manipulation. A modest positive relationship between these two methods was observed, suggesting that shifting behaviour is relatively predictive across different manipulations of shifting. Overall, results from both experiments suggest that response bias shifting, like response bias setting, is a relatively stable behaviour within individuals despite changes in test domain and test manipulation.  相似文献

Learning is an important aspect of cognition that is crucial for the success of many species, and has been a factor involved in the evolution of distinct patterns of life history that depend on the environments in question. The extent to which different degrees of social and individual learning emerge follows from various species-dependent factors, such as the fidelity of information transmission between individuals, and that has previously been modelled in agent-based simulations with meme-based representations of learned knowledge and behaviours. A limitation of that previous work is that it was based on fixed environments, and it is known that different learning strategies will emerge depending on the variability of the environment. This paper will address that limitation by extending the existing modelling framework to allow the simulation of life history evolution and the emergence of appropriate learning strategies in changing environments.  相似文献

心理差异量对儿童青少年分类活动影响的研究   总被引:4,自引:1,他引:3  
本研究选择自制的、被试从前未看过的墨渍图为实验材料,探讨心理差异量对分类活动的影响。以40名11-20岁儿童青少年为被试,一方面使用速示仪测量墨渍图之间的心理差异量,一方面要求被试对墨渍图进行自由分类,并说明理由。结果发现:①心理差异量直接影响分类结果。②心理差异量在11岁、14岁与17岁、20岁之间存在着非常显著的差异(P〈0.01)。③分类标准的选择的年龄差异主要表现在分类标准的复杂性方面。  相似文献

The mood disorder work group has proposed to eliminate the bereavement exclusion criterion from the diagnosis of major depression in the 5th edition of the American Psychiatric Association's (2012) Diagnostic and Statistical Manual of Mental Disorders. The proposal would break tradition with the long‐held distinction between depression and normal bereavement. This article reviews the development of the bereavement exclusion, discusses evidence for and against the proposal, and offers some relevant implications for counselors in light of the research on depression and bereavement.  相似文献

Finite sample inference procedures are considered for analyzing the observed scores on a multiple choice test with several items, where, for example, the items are dissimilar, or the item responses are correlated. A discrete p-parameter exponential family model leads to a generalized linear model framework and, in a special case, a convenient regression of true score upon observed score. Techniques based upon the likelihood function, Akaike's information criteria (AIC), an approximate Bayesian marginalization procedure based on conditional maximization (BCM), and simulations for exact posterior densities (importance sampling) are used to facilitate finite sample investigations of the average true score, individual true scores, and various probabilities of interest. A simulation study suggests that, when the examinees come from two different populations, the exponential family can adequately generalize Duncan's beta-binomial model. Extensions to regression models, the classical test theory model, and empirical Bayes estimation problems are mentioned. The Duncan, Keats, and Matsumura data sets are used to illustrate potential advantages and flexibility of the exponential family model, and the BCM technique.The authors wish to thank Ella Mae Matsumura for her data set and helpful comments, Frank Baker for his advice on item response theory, Hirotugu Akaike and Taskin Atilgan, for helpful discussions regarding AIC, Graham Wood for his advice concerning the class of all binomial mixture models, Yiu Ming Chiu for providing useful references and information on tetrachoric models, and the Editor and two referees for suggesting several references and alternative approaches.  相似文献

读者的元理解监测为什么不精确?   总被引:1,自引:0,他引:1       下载免费PDF全文
精确的元理解监测对随后的元理解控制和阅读理解有重要作用,但是,通常情况下,读者的元理解监测并不精确。回顾20余年的元理解监测研究,发现元理解监测的精确性主要受制于阅读材料特征、监测线索与标准测验特征等因素。未来研究应注意元理解监测的判断形式、监测线索及评价标准对元理解监测精确性的交互关联影响。  相似文献

论三段论推理过程中结论正确性的两种判断标准   总被引:3,自引:1,他引:3       下载免费PDF全文
人们进行三段论推理加工时是根据什么标准来判定推理结论的正确性的?实验结果支持下述观点:人们在进行三段论推理过程中,在判定推理结论的正误时,存在两种判定标准:一种是“形式标准”,另一种是“内容标准”;两种判定标准对于人们判定结论的正确性都有影响,哪个判定标准的影响力更大依赖于人们已掌握的知识结构。  相似文献
