文本阅读中情境模型空间维度的非线索更新

采用实时窗口阅读技术,探讨文本阅读中不同研究范式下空间信息更新的特点。结果表明,阅读中情境模型空间信息的非线索实时更新是存在的,但要实现这种更新则需要一定的条件。相对于自动呈现材料,在更为自由的手动阅读条件下,先前阅读的空间信息,尤其是外显的位置信息（如“广场”）能够进行非线索的实时更新（实验一、实验二）;此外,实验三的结果表明,不同的探测位置对空间信息的通达也产生了影响。在更为敏感的探测位置上,内隐的空间实体信息（如,“雕像”）也表现出了非线索的更新。     

决策中个体差异研究现状述评

决策中个体差异的研究有助于进一步检验和深化传统决策理论。文章回顾了近十年决策个体差异研究的主要变量（人格、认知能力、认知风格和年龄）和研究结果,并简要总结了该类研究的背景、研究范式和理论意义。这些研究一致发现个体差异变量对决策过程、决策表现等具有影响作用,说明个体差异与决策加工中复杂的人-情境间联系有关。文章提出,未来研究应该综合考虑决策情境、情绪和决策主体的理论模型,以期对个体差异在决策中的作用做出更好解释     

Do Health Care Workplaces Affect Treatment Environments?

Previous research has demonstrated that characteristics of the health care workplace influence staff outcomes such as morale and burnout, but the potential effect of health care workplaces on the treatment environment has been little studied. Building on a model proposed by Schaefer and Moos (1993), we propose that the workplace factors of supervisory work environment (e.g. support from supervisors, managerial control) and programme philosophical orientation (e.g. disease model of addiction, psychosocial learning model of addiction) predict four treatment environment elements: patient autonomy, staff control, staff sensitivity, and patient alienation. Multiple regression analysis of data drawn from a survey (response rate = 86%) of 327 staff members at 15 Veterans Affairs (VA) inpatient substance abuse treatment programmes revealed that greater managerial control over staff predicted greater patient alienation, lower staff sensitivity towards patients, and greater staff control over patients. Stronger disease model programme orientations predicted less patient alienation and greater staff sensitivity, whereas stronger psychosocial model programme orientations predicted less staff control. These results suggest that health care workplaces may influence treatment environments. Implications for further research and practice are discussed. © 1997 John Wiley & Sons, Ltd.     

The operation of Lake Kariba: A multiobjective decision analysis

The paper describes a successful application of Bayesian decision analysis to the operation of the Lake Kariba hydropower system. This management problem is complicated by the high uncertainty of the inflow process, multiple and conflicting objectives and the influence of time on some of the parameters in the management task. Inflows to the reservoir are forecast through dynamic linear models. Managerial preferences are modelled through a multiattribute utility function. Since the solution of the exact model is computationally too demanding, a heuristic method is applied to find a feasible control strategy. A comparison with results obtained by methods used previously demonstrates the superiority of the methodology presented here.     

COMMENTS ON SANBORN BROWN'S “CAN PHYSICS CONTRIBUTE TO THEOLOGY?”

Abstract. Sanborn Brown raised in a preliminary form issues relating to science and religion that have been subjects for increasingly more sophisticated discussion over the intervening forty years.     

习得无助理论模型的演变与争议

习得无助理论是由美国心理学家马丁．塞里格曼于上世纪60年代提出、而后在美国以至全世界引起广泛研究热潮的一种心理学理论,围绕着习得无助产生的机制及实验操作中的关键变量,形成了许多有价值的理论模型。该研究介绍了这些理论模型的起源、发展与演变．以及无助现象对人们的认知、情绪和动机造成的损害,为我们在临床上诊断和治疗抑郁提供了一个新的视角,同时为预测和矫治学生的习得无肋感提供了方法上的借鉴。     

Models for a paraconsistent set theory

In this paper the existence of natural models for a paraconsistent version of naive set theory is discussed. These stand apart from the previous attempts due to the presence of some non-monotonic ingredients in the comprehension scheme they fulfill. Particularly, it is proved here that allowing the equality relation in formulae defining sets, within an extensional universe, compels the use of non-monotonic operators. By reviewing the preceding attempts, we show how our models can naturally be obtained as fixed points of some functor acting on a suitable category (stressing the use of fixed-point arguments in obtaining such alternative semantics).     

A cognitive model in which representations are images

Interpretations of images of the brain are starting to reveal the conceptual tasks in which the person was engaged at the time of imaging. Existing mathematical models can explain the patterns of activity observed in such images in terms of the coherent activity of large populations of neurons, but not in terms of cognition. This paper is an early investigation into how such patterns might provide the internal representations for a cognitive system. Probes, working memories and memories are all represented as images. The accompanying process model describes how attention is set according to the contents of working memory, how attention determines what parts of the probe are memorised, how memories are activated according to similarity to the probe in areas in attention, and how working memory is managed. The model is demonstrated on re-creations of classic simulations of recognition memory and categorisation.     

Models Clarified: Responding to Langdon Gilkey

We respond to concerns raised by Langdon Gilkey. The discussion addresses the nature of theological thinking today, the question of truth within the situation of pluralism, the identity and difference between theological models and scientific models, and the proposed methods for testing theological models.     

Reducing ethnic prejudice: an evaluation of seven recommended principles for incorporation in public campaigns

The present study investigated the effects of seven principles drawn from cognitive models of ethnic prejudice, general information processing models and persuasion models, on levels of ethnic prejudice. It was hypothesized that exposure to cue cards incorporating these principles would result in lower levels of prejudice than cue cards which did not incorporate the principles. A total of 400 caucasian participants were randomly assigned to experimental conditions (where participants were exposed to a cue card incorporating or omitting each of the seven principles), or the control condition (with no cue card exposure), and completed a questionnaire measuring ethnic prejudice. Results revealed that the absence of the principles in the cards led in several cases to unwanted negative effects (higher levels of prejudice than the control group). Reasons for these findings and implications for launching poster campaigns to reduce ethnic prejudice are discussed. Copyright © 2003 John Wiley & Sons, Ltd.
