三维动静态场景下返回抑制的扩散

使用虚拟现实技术探讨三维动静态空间下返回抑制是否敏感于深度线索及返回抑制效应是否存在空间扩散。采用线索−靶子范式,分别设置三维静态和动态场景。结果发现：三维静态场景,不同深度及不同侧位置均发生返回抑制且产生效应大小有差异;三维动态场景,不同线索条件反应时无显著差异。结果表明,三维静态场景下,返回抑制敏感于深度线索,其效应在空间中存在扩散;客体运动破坏了返回抑制的产生及其效应的空间扩散。     

NATURAL GOODNESS,RIGHTNESS, AND THE INTERSUBJECTIVITY OF REASON: REPLY TO ARROYO,CUMMISKEY, MOLAND,AND BIRD‐POLLAN

Abstract: In response to Arroyo, I explain my position on the concept of “natural goodness” and how my use of that concept compares to that of Geach and Foot. An Aristotelian or functional notion of goodness provides the material for Kantian endorsement in a theory of value that avoids a metaphysical commitment to intrinsic values. In response to Cummiskey, I review reasons for thinking Kantianism and consequentialism incompatible, especially those objections to aggregation that arise from the notion of the natural good previously described. In response to Moland, I explain why I think Hegelian worries about the supposed emptiness of the Kantian self do not apply to my account. And in response to both Moland and Bird‐Pollan, I argue that, contrary to the view of some Hegelians, the intersubjective normativity of reason is not something developed through actual social relations; rather, it is something essential to an individual's relations with himself or herself.     

FREE WILL ACCORDING TO JOHN DUNS SCOTUS AND NEUROSCIENCE

Abstract. This paper examines two views of free will. It looks first at the fourteenth‐century religious insights of John Duns Scotus, one of history's seminal thinkers about free will. It then examines what current neuroscience tells us about free will. Finally, it summarizes the past and present views and concludes by answering two questions: Does free will refer to an absence of external constraint, or does it refer to a human ability to decide in an acausal manner?     

发散思维的序列位置效应：创新想法动态产生机制的新视角

发散思维的序列位置效应是指随着时间的推移,单位时间内想法生成的数量逐渐降低,但想法的独创性逐渐升高的现象。联想理论和执行控制假说分别侧重对序列位置效应的个体差异和认知加工过程进行解释。神经影像学研究表明,在想法产生的整个阶段序列位置效应依赖于默认网络后部和突显网络的持续增强激活和协同合作;在想法产生的后期阶段,颞-顶区域alpha能量值以及执行控制网络与默认网络的协同模式增强。未来研究需要结合语义和神经动态分析等技术,对序列位置效应的特异性机制、动态加工机制以及影响因素进行深入探究,从而为解构创新思维的动态过程提供新的视角。     

风险情景中不同成就动机者的冒险行为特征

采用计算机模拟和问卷的方法,研究不同成就动机的个体在动态情境下的冒险行为。结合成就动机的静态与动态理论,考察具有不同程度的成就动机个体在动态环境中的行为差异。结果发现,在动态情境的初期,可以看到不同成就动机的被试有稳定的偏好：成就动机高的个体偏爱中等难度的任务,成就动机低的个体偏爱较易或者是较难难度的任务;随着行为的动态进行,个体的冒险行为呈现出与静态情境中不同的规律性：成就动机高的个体在初期选择的中等难度的基础上逐渐选择更难的任务;成就动机低的个体在初期选择较易难度任务的基础上也逐渐选择更难的任务;相对于成就动机低的个体,成就动机高的个体会更慢地选择难度高的任务;高成就动机个体出现非典型转换次数显著低于低成就动机的个体。     

集体问题解决中的认知表征、行为惯例和动态能力

以王建安和张钢(2008)开发的三人TTT纸牌游戏(原游戏)及其变式(变式游戏)为实验任务, 研究了集体问解决中认知表征和行为惯例对提高动态能力的作用。共有240名被试, 分成80个三人小组, 参加了前后两场各20盘游戏。80个小组按照是否被告知游戏的问题表征(即有无认知表征), 以及是玩原游戏还是玩变式游戏, 均分成4个区组来玩第一场游戏。在第二场游戏中, 4个区组都玩变式游戏。以玩每盘游戏的平均步时和在问题表征中走过的路径为指标测量惯例, 以玩第一场原游戏习得的能力向玩第二场变式游戏的迁移率来衡量动态能力。结果发现：一方面, 适当的认知表征有助于提高集体问题解决的动态能力; 另一方面, 没有适当认知表征支持的行为惯例反而会阻碍动态能力的发展。概括地说, 动态能力的决定因素是认知表征而不是行为惯例。     

Stochastic choice models: A comparison between Bush-Mosteller and a source-independent reward-following model

Horner and Staddon (1987) argued that a class of reward-following processes defined by a property they termed ratio invariance is a better model for the probabilistic choice performance of pigeons than competing molecular accounts such as momentary maximizing, melioration, and the Bush-Mosteller model. The critical data were provided by choice distributions-distributions of a variable S, the proportion of Right choices, defined on a moving window typically 32 choices long-obtained under a frequency-dependent schedule. The schedule prescribed equal payoff probabilities, p(S), for both choices. p(S) was a maximum when S = 0.5 and declined linearly for S values above and below 0.5. Pigeons showed generally bimodal choice distributions with the modes at equal p(S) values. These data do not follow easily from melioration or momentary maximizing and are inconsistent with molar maximizing, but they may be consistent with Bush-Mosteller. We present here the results of computer simulations showing that the ratio-invariance model studied yields, as expected, choice modes at equal p(S) values, but that Bush-Mosteller, although capable of generating bimodal choice distributions, does not have choice modes at equal p(S) values.     

精神分析中的主体间性研究

采取主体间性的视角,对精神分析中以治疗关系为核心的工作实践的演变与发展进行探讨。通过研究客体关系学派、拉康精神分析、人际精神分析以及主体间性精神分析在工作实践中的关注焦点与互动形式的差异,探讨患者主体与治疗师主体的主客关系的不同理念的演变,以及语言在主体间互动的重要作用。结论认为在主体间性的视角下,精神分析中的治疗关系与互动向着三个方面发展：治疗关系在根本上是超越的;治疗关系在实践上是双向开放的,是共同参与的;在工作实践中更关注语言诠释的主体以及非语言的互动。

     

Emmanuel Levinas,Radical Orthodoxy,and an Ontology of Originary Peace

Radical Orthodoxy, a growing movement among contemporary Christian theologians, argues that the prominent philosophical paradigms of modern and postmodern thought lack transcendence, are ultimately nihilistic, and are guided by an ontology of violence. Among the thinkers Radical Orthodoxy criticizes are Hegel, Nietzsche, and Hobbes, but surprisingly also the Jewish philosopher Emmanuel Levinas, whom they claim offers an ethics for nihilists. In this essay, I analyze the claims of two prominent thinkers in Radical Orthodoxy, John Milbank and Catherine Pickstock, and argue that their account of Levinas is not only unfounded but point out the ways in which Levinas himself is also just as critical of the prevailing ontology of violence that figures in modern accounts of intersubjectivity and politics. Indeed, in his own way, Levinas also offers an ontology of peace, making him an important dialogue partner for Radical Orthodoxy's construction of an alternative ethics and politics.     

A joint modeling framework of responses and response times to assess learning outcomes

Abstract

A general modeling framework of response accuracy and response times is proposed to track skill acquisition and provide additional diagnostic information on the change of latent speed in a learning environment. This framework consists of two types of models: a dynamic response model that captures the response accuracy and the change of discrete latent attribute profile upon factors such as practice, intervention effects, and other latent and observable covariates, and a dynamic response time model that describes the change of the continuous response latency due to change of latent attribute profile. These two types of models are connected through a parameter, describing the change rate of the latent speed through the learning process, and a covariate defined as a function of the latent attribute profile. A Bayesian estimation procedure is developed to calibrate the model parameters and measure the latent variables. The estimation algorithm is evaluated through several simulation studies under various conditions. The proposed models are applied to a real data set collected through a spatial rotation diagnostic assessment paired with learning tools.
