3～6岁儿童信念理解能力的发展研究

研究设计了冲突真实信念任务,用于考察儿童对真实信念的理解;并利用区分信念、冲突真实信念和意外地点的错误信念任务,考察儿童理解信念推理基本规则、真实信念和错误信念的发展顺序。97名3~6岁儿童完成了测试。结果显示,3岁儿童能理解信念推理的基本规则,5岁儿童能理解真实信念,6岁儿童能理解错误信念。结果支持了儿童先理解真实信念,后理解错误信念的发展模式;也说明在理解信念以前儿童已能掌握信念推理的基本规则。     

Hume's atheism and the role of Cleanthes

This is a reply to Willem Lemmens' discussion of my interpretation of the Dialogues on Natural Religion in my 2000 collection Themes from Hume: Self, Will, Religion. I use Lemmens' careful textual analysis to clarify my considered position and to further the reading of Part 12 of the Dialogues.     

Counter‐Interrogation Strategies when Anticipating Questions on Intentions

The present experimental study adds to the emerging line of psycholegal research focusing on true and false intentions. It is the first to examine mock suspects' (N = 120) counter‐interrogation strategies in investigative interviews in which they anticipate questions on their intentions. As planning is an inherent part of many intentions, mock suspects were, in addition to questions on their intentions, asked a set of questions that pertained to the planning phase in which they formed their intentions. Besides ratings of the anticipation and difficulty of the questions, participants were asked to provide their principal strategy for being perceived as truthful. Both truth tellers and liars perceived the questions on the planning phase as significantly more unanticipated than the questions on their intentions. Furthermore, liars perceived the questions on the planning phase as more difficult to answer than did truth tellers. Liars and truth tellers differed with respect to their principal strategy employed for being perceived as truthful. Liars' most commonly used strategy was to stick to the cover story, whereas truth tellers' most common strategy was to be honest. The results are discussed in relation to the unanticipated questions approach and psychological concepts such as the illusion of transparency. Copyright © 2012 John Wiley & Sons, Ltd.     

Knowledge and True Belief at Theaetetus 201a–c

This paper examines a passage in the Theaetetus (201a–c) where Plato distinguishes knowledge from true belief by appealing to the example of a jury hearing a case. While the jurors may have true belief, Socrates puts forward two reasons why they cannot achieve knowledge. The reasons for this nescience have typically been taken to be in tension with each other (most notably by Myles Burnyeat). This paper proposes a solution to the putative difficulty by arguing that what links the two cases of nescience is that in neither case do the jurors act from an epistemic virtue and that doing so is a necessary condition of knowledge. Appreciating that it is a necessary condition of knowledge that it be the result of an epistemic agent's agency in a distinctive way provides a satisfying solution to the difficulty Burnyeat detected and also does justice to an otherwise neglected aspect of Plato's epistemology: his talk of cognitive capacities and virtues and his focus on what it is that is active and passive in epistemic processes.     

Statistical inference for multiple choice tests

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.     

The Failed Courage of the Fanatic

Fanatic acts are carried out by those who regard their inner being as having to be denied. By means of a projective identification to a leader and a strident religious cause, they experience their unworthy and evil self as having to be sacrificed so that their good self—as projected on the leader and the cause—can survive and reign. True prophets, as contrasted with the leaders of fanatic groups, do not teach their disciples to hate and flee those who oppose them; but, instead, to build a better world by coming caringly together with their adversaries to heal the wounds of loneliness, shame, and self-hatred.     

The ‘true religion’ of the sceptic: Penelhum reading Hume's Dialogues

According to Terence Penelhum, Philo's confession in the last part of Hume's Dialogues Concerning Natural Religion reveals on the side of the author a reconciliatory and pacifying attitude towards the liberal moderate clergy of his days. This article investigates whether another reading of this intriguing text is not more appropriate. It defends the idea that Philo's speeches and Cleanthes' reactions to it in the last part of the Dialogues reveal on Hume's side an attitude of mild despair and isolation towards the religious culture of eighteenth-century Scotland, in both its orthodox and more moderate form.     

Jesus and Muhammad

This essay foregrounds the reformatory teachings of two of the greatest men that walked the earth – Jesus and Muhammad. The majority of the followers of these honoured prophets attribute their success to the power and influence of their transcultural theologies and see them as nothing more than founders of independent religions. Another presumption is that their religions are mutually exclusive. This essay looks beyond creedal orthodoxies and inflexible articles of faith to find commonalities in the approaches of prophets Jesus and Muhammad while exploring the possibility of imagining their missions as liberatory responses to the socio-political conditions that prevailed during their times.     

Some Thoughts about the Hardest Logic Puzzle Ever

The Hardest Logic Puzzle Ever was first described by the late George Boolos in the Spring 1996 issue of the Harvard Review of Philosophy. Although not dissimilar in appearance from many other simpler puzzles involving gods (or tribesmen) who always tell the truth or always lie, this puzzle has several features that make the solution far from trivial. This paper examines the puzzle and describes a simpler solution than that originally proposed by Boolos.     

Classical Test Theory as a first-order Item Response Theory: Application to true-score prediction from a possibly nonparallel test

We give an account of Classical Test Theory (CTT) in terms of the more fundamental ideas of Item Response Theory (IRT). This approach views classical test theory as a very general version of IRT, and the commonly used IRT models as detailed elaborations of CTT for special purposes. We then use this approach to CTT to derive some general results regarding the prediction of the true-score of a test from an observed score on that test as well from an observed score on a different test. This leads us to a new view of linking tests that were not developed to be linked to each other. In addition we propose true-score prediction analogues of the Dorans and Holland measures of the population sensitivity of test linking functions. We illustrate the accuracy of the first-order theory using simulated data from the Rasch model, and illustrate the effect of population differences using a set of real data.This research is collaborative in every respect and the order of authorship is alphabetical. It was begun when both authors were on the faculty of the Graduate School of Education at the University of California, Berkeley.We would like to thank both Neil Dorans, Skip Livingston and two anonymous referees for many suggestions that have greatly improved this paper.
