On Selective Left Neglect during Walking in a Child

In this article we describe a child affected by right parieto-occipital lesion due to head injury. The patient showed left hemianopia, but not unilateral spatial neglect on traditional paper-and-pencil tests and on "ecological" tests. However, his parents reported frequent collisions with obstacles on the left side. A specific test was set up: The patient had to kick down skittles put on both sides of a route traced on the floor. He kicked down 89% of skittles on the right, but only 38% on the left side. These findings are discussed in light of recent theories on unilateral neglect.     

Self-control and frequency of model presentation: Effects on learning a ballet passé relevé

The purpose of this experiment was to examine the combined effects of self-control and frequency of model presentation on learning a complex motor skill, i.e., ballet passé relevé. Before practice started self-control participants were asked to choose two viewings or six viewings (before practice and then every five trials) and the externally controlled groups were yoked to their self-control counterparts. All participants completed 15 acquisition trials followed by 5 trials for the immediate and 5 trials for the delayed retention tests 48 hours later. Dependent variables included cognitive representation scores, physical reproduction rankings, and balance time. Statistical analyses indicated that under limited physical practice conditions self-control and higher frequency of model presentation facilitated the development of cognitive representation and did not produce further benefits in movement reproductions and balance time. The results were discussed with respect to the social cognitive theory.     

Inferring hidden causal structure

We used a new method to assess how people can infer unobserved causal structure from patterns of observed events. Participants were taught to draw causal graphs, and then shown a pattern of associations and interventions on a novel causal system. Given minimal training and no feedback, participants in Experiment 1 used causal graph notation to spontaneously draw structures containing one observed cause, one unobserved common cause, and two unobserved independent causes, depending on the pattern of associations and interventions they saw. We replicated these findings with less-informative training (Experiments 2 and 3) and a new apparatus (Experiment 3) to show that the pattern of data leads to hidden causal inferences across a range of prior constraints on causal knowledge.     

以实质心理学为基础的评估：认知诊断

评价除了了解学习者的学习情况外,同时还应该提供学习者学习状况的诊断信息,以利于教学与学习。评价应该以认知心理学对学习过程的研究,作为编制测验的实质理论依据,进行认知诊断评估。本文针对认知诊断的心理学基础：知识的习得、知识诱发、知识表征、知识结构等进行梳理,以便测验开发者对认知诊断评估有更清晰的认识。

Narrative Representation and Phenomenological Knowledge

The purpose of this paper is to demonstrate that narrative representations can provide knowledge in virtue of their narrativity, regardless of their truth value. I set out the question in section 1, distinguishing narrative cognitivism from aesthetic cognitivism and narrative representations from non-narrative representations. Sections 2 and 3 argue that exemplary narratives can provide lucid phenomenological knowledge, which appears to meet both the epistemic and narrativity criteria for the narrative cognitivist thesis. In section 4, I turn to non-narrative representation, focusing on lyric poetry as presenting a disjunctive objection: either lucid phenomenological knowledge can be reduced to identification and fails to meet the epistemic criterion, or lucid phenomenological knowledge is provided in virtue of aesthetic properties and fails to meet the narrativity criterion. I address both of these problems in sections 5 and 6, and I close with a tentative suggestion as to how my argument for narrative cognitivism could be employed as an argument for aesthetic cognitivism.     

Harry Potter and Contemporary Magic: Fantasy Literature,Popular Culture,and the Representation of Religion

This article discusses the reasons for the religious reactions to the Harry Potter novels, arguing that the books contribute to, and reflect, the reconfiguration of religion in contemporary society. The article analyses the media qualities of fantasy literature and the specific representation of magic in the novels and argues that these aspects form an important part of the reasons for the religious reactions. Fantasy literature and other popular culture that represents and mediates religious expressions and phenomena actively contribute to the reconfiguration of, and communication about, religion in contemporary society and are thus of consequence for what we understand ‘religion’ to be in the study of religions.     

Emotional,Sensitive, and Unfit for Office? Gender Stereotype Activation and Support Female Candidates

Women are underrepresented at all levels of elected office. It is suspected that gender stereotypes hinder the electoral success of female candidates, but empirical evidence is inconclusive on whether stereotypes have a direct effect on voting decisions. This empirical conflict stems, in part, from the assumption that voters automatically rely on gender stereotypes when evaluating female candidates. This study explicitly tests the assumption of automatic stereotype activation. I suggest that stereotype reliance depends on whether stereotypes have been activated during a campaign, and it is only when stereotypes are activated that they influence evaluations of female candidates. These hypotheses are tested with a survey experiment and observational analysis. The results show that campaign communication activates stereotypes when they otherwise might not be activated, thereby diminishing support for female candidates.     

Palestinian Educational Philosophy Between Past and Present

The article discuses the education issue as a central and decisive factor inshaping, reproducing and representing individual and collective identity.I present the Palestinian case study because the Palestinian people are atthe present in a very critical period of constructing their national identityand education is part of the nation-building project. I have chosen to studytwo periods in the life of Palestinians, 1972 during the revolution and thepresent 1999 the start of the establishment of an independent Palestinianentity and to examine how the economic, social, political conditions etc.affect the formation of the educational philosophy of those periods; aneducational philosophy that will affect the formation of education and theformation of private and collective consciousness.     

Probability, logic and the cognitive foundations of rational belief

Since Pascal introduced the idea of mathematical probability in the 17th century discussions of uncertainty and “rational” belief have been dogged by philosophical and technical disputes. Furthermore, the last quarter century has seen an explosion of new questions and ideas, stimulated by developments in the computer and cognitive sciences. Competing ideas about probability are often driven by different intuitions about the nature of belief that arise from the needs of different domains (e.g., economics, management theory, engineering, medicine, the life sciences etc). Taking medicine as our focus we develop three lines of argument (historical, practical and cognitive) that suggest that traditional views of probability cannot accommodate all the competing demands and diverse constraints that arise in complex real-world domains. A model of uncertain reasoning based on a form of logical argumentation appears to unify many diverse ideas. The model has precursors in informal discussions of argumentation due to Toulmin, and the notion of logical probability advocated by Keynes, but recent developments in artificial intelligence and cognitive science suggest ways of resolving epistemological and technical issues that they could not address.
