政策执行偏差严重程度对公众地方政府责任判断的影响机制

为探讨地方政府政策执行偏差严重程度对公众地方政府责任判断的影响机制。采用问卷法对728名社会公众进行调查,结果显示：（1）公众地方政府有意性判断和公众地方政府可控归因中介了政策执行偏差严重程度与公众地方政府责任判断之间的关系。（2）政策执行偏差严重程度还通过公众地方政府有意性判断→公众地方政府可控归因的中介链作用于公众地方政府道德责任判断。并对研究的实践启示进行了讨论。     

反应抑制的训练:内容、效果与机制

近期的研究发现,个体的反应抑制能力具有一定的可塑性。研究者多采用双盲随机对照实验设计,训练的对象包括儿童、成人和特殊群体,研究者通过Go/Nogo、Stop-signal等任务进行为期1周至3周,45至7200试次不等的抑制控制能力训练,并结合行为、脑电以及脑成像等技术对训练效果进行评估,研究结果发现,接受了抑制控制训练的个体其抑制能力得到提升,并伴随脑神经活动的变化。另外,研究者发现,抑制控制能力的训练效果还可以迁移至个体日常生活中的表现。但是,也有些研究并未发现抑制控制训练的效果。训练任务的设置,评估任务的选择以及被试反应策略的差异等因素可能会影响训练的效果。抑制控制训练引发行为与大脑活动的变化可能是由于训练导致了个体建立了自上而下有意识的抑制控制模式和自下而上的自动抑制模式。反应抑制和冲突抑制可塑性的比较,儿童与老年人抑制功能的训练以及训练效果的追踪研究将成为该领域日后研究的重点问题。     

WHY I AM AN ACCOMMODATIONIST AND PROUD OF IT

There is a strong need of a reasoned defense of what was known as the “independence” position of the science–religion relationship but that more recently has been denigrated as the “accommodationist” position, namely that while there are parts of religion—fundamentalist Christianity in particular—that clash with modern science, the essential parts of religion (Christianity) do not and could not clash with science. A case for this position is made on the grounds of the essentially metaphorical nature of science. Modern science functions because of its root metaphor of the machine: the world is seen in mechanical terms. As Thomas Kuhn insisted, metaphors function in part by ruling some questions outside their domain. In the case of modern science, four questions go unasked and hence unanswered: Why is there something rather than nothing? What is the foundation of morality? What is mind and its relationship to matter? What is the meaning of it all? You can remain a nonreligious skeptic on these questions, but it is open for the Christian to offer his or her answers, so long as they are not scientific answers. Here then is a way that science and religion can coexist.     

Dev E-R: A computational model of early cognitive development as a creative process

This paper describes a computational model named Dev E-R (Developmental Engagement-Reflection) that, inspired by Piaget’s theory, simulates the assimilation-accommodation adaptation process. It is implemented with a new extended version of the computational model of creativity known as Engagement-Reflection. That is, this model simulates adaptation as a creative activity. We introduce here the implementation of our model on an agent that is initialized with basic reflex conducts and that through the interaction with a 3D virtual world, it is able to build new behaviors autonomously. The new acquired skills, according to Piaget’s theory, are typically observed in children that have reached the second substage of the sensorimotor period.     

An investigation of DIF mechanisms in the context of differential testlet effects

This study investigated differential item functioning (DIF) mechanisms in the context of differential testlet effects across subgroups. Specifically, we investigated DIF manifestations when the stochastic ordering assumption on the nuisance dimension in a testlet does not hold. DIF hypotheses were formulated analytically using a parametric marginal item response function approach and compared with empirical DIF results from a unidimensional item response theory approach. The comparisons were made in terms of type of DIF (uniform or non‐uniform) and direction (whether the focal or reference group was advantaged). In general, the DIF hypotheses were supported by the empirical results, showing the usefulness of the parametric approach in explaining DIF mechanisms. Both analytical predictions of DIF and the empirical results provide insights into conditions where a particular type of DIF becomes dominant in a specific DIF direction, which is useful for the study of DIF causes.     

重新认识心衰机制中的心脏舒张期耗能

长期以来,对心衰和心衰机制的认识一直存在争议,所以心衰的治疗一直是国内外心血管领域中的一个挑战.为了澄清心衰机制的内涵,本文用弗兰克-斯塔灵定律以及能量守恒定律作为重建心脏理论以及心衰机制的依据,论证了心脏的做功是从动能向势能,又从势能向动能的转换过程.并根据临床事实等来证实心脏舒张是在作功,与收缩期作功是等同的.没有心脏的舒张就没有心脏的收缩,心脏功能下降实际上是舒张与收缩功能同时的下降.不存在有收缩功能正常的舒张功能下降.心功能的判定标准不能采用射血分数,而应该采取能量消耗的定量方法来测定.     

幸福的体验效用与非理性决策行为的偏差机制

基于体验效用的幸福包括预期幸福、即时幸福和回忆幸福,这三者有极其重要的本质差异,导致决策偏差和非理性。本研究运用行为科学和认知神经科学相结合的研究方法,首次从行为层次—信息加工层次—脑神经层次三个层面,立体地开展幸福感的体验效用与非理性决策行为研究。研究计划分为三个部分:(1)预期幸福、即时幸福和回忆幸福的本质特点和行为规律;(2)三种体验效用产生偏差的认知心理机制;(3)体验效用与非理性决策偏差的脑神经机制。通过系列研究,拟解决三个关键问题:(1)在人类判断与决策过程中,预期、即时和回忆三种效用是如何影响人们的判断与决策?(2)三种体验效用出现偏差的信息加工特点和脑神经机制究竟是什么?(3)三种效用的偏差规律及对政府公共政策的启示。对这些问题的深入探讨,不仅对决策理论研究的发展是一个贡献;对政府管理制定有效的公共政策,避免"牺牲体验追求指标",解决"幸福悖论",同样有很强的实践指导意义。     

Inconsistent child-rearing: A reply to rosenthal

Abstract

In a reply to our paper (Kohlmann, Schumacher, & Streit, 1988), Rosenthal (in a Letter to the Editors, this issue) primarily gives some comments on findings regarding the association of inconsistent child-rearing behavior and anxiety in the child. Results of our study were compared to results from a study by Rosenthal, Finkelstein, Ni, and Robertson (1959).     

不同年龄广告名人效应的心理加工机制研究

本研究从自动化加工和控制性加工这个视角研究了名人效应的心理加工机制。实验运用加工分离程序,探讨了不同年龄阶段的受众对名人广告的信息加工模式。结果发现：(1)名人效应是一个普遍存在的现象,与用一般消费者做代言人相比,青少年、成年人(大学生)以及老年人对名人广告均明显存在更多的自动化加工,且加工水平没有年龄差异。但是,老年人的控制性加工明显低于其他两组;(2)在非注意条件下,代言人的专业化程度明显地影响了大学生组的控制性加工,但与各组被试的自动化加工都关系不大。这些研究发现为广告策略的制定带来了一些新的启示。     

Self-deception as affective coping. An empirical perspective on philosophical issues

In the philosophical literature, self-deception is mainly approached through the analysis of paradoxes. Yet, it is agreed that self-deception is motivated by protection from distress. In this paper, we argue, with the help of findings from cognitive neuroscience and psychology, that self-deception is a type of affective coping.First, we criticize the main solutions to the paradoxes of self-deception. We then present a new approach to self-deception. Self-deception, we argue, involves three appraisals of the distressing evidence: (a) appraisal of the strength of evidence as uncertain, (b) low coping potential and (c) negative anticipation along the lines of Damasio’s somatic marker hypothesis. At the same time, desire impacts the treatment of flattering evidence via dopamine. Our main proposal is that self-deception involves emotional mechanisms provoking a preference for immediate reward despite possible long-term negative repercussions. In the last part, we use this emotional model to revisit the philosophical paradoxes.
