Formal modeling and analysis of cognitive agent behavior

From an external perspective, cognitive agent behavior can be described by specifying (temporal) correlations of a certain complexity between stimuli (input states) and (re)actions (output states) of the agent. From an internal perspective the agent's dynamics can be characterized by direct (causal) temporal relations between internal and mental states of the agent. The latter type of specifications can be represented in a relatively simple, executable format, which enables different types of analysis of the agent's behavior. In particular, simulations of the agent's behavior under different (environmental) circumstances can be explored. Furthermore, by applying verification techniques, automated analysis of the consequences of the agent's behavior can be carried out. To enable such types of analysis when only given an external behavioral specification, this has to be transformed first into some type of executable format. An automated procedure for such a transformation is proposed in this paper. The application of the transformation procedure is demonstrated for a number of cases, showing examples of the types of analysis as mentioned for different forms of behavior.     

情绪复杂性对精神症状的影响途径及干预技术

情绪复杂性指的是个体情绪体验的多样性和分化度。情绪复杂性影响了精神症状的形成, 它不仅通过改变情绪调节策略的频率和程度来影响精神症状, 而且会影响情绪调节策略和精神症状之间的关系。基于情绪复杂性的干预增加了暴露治疗的疗效。正念能提升情绪复杂性, 但两者的作用机制可能有所差别。情绪复杂性的多角度测量、作用条件及脑机制应成为今后在临床领域的研究方向。     

情绪复杂性：探讨情绪功能的新视角

情绪复杂性指个体情绪体验的多样性、广泛性和深刻性。可从情绪觉察能力和混合情绪两个角度测量情绪复杂性。情绪复杂性既受个体注意分配能力, 社会认知技能和某些人格特质的影响, 也与所处情境密切相关。此外, 情绪复杂性还存在年龄与文化差异。维持情绪复杂性对个体的认知功能和身心健康有重要意义, 如增加个体的环境适应能力和帮助个体从压力中更快恢复。正念训练和情绪聚焦疗法是两种增进情绪复杂性的心理干预手段。     

The Problematics of Human Subjectivity: Gilles Deleuze and the Deweyan Legacy

This article is part of alarger project exploring the continuity betweentwo philosophical positions – that of Frenchpoststructuralist Gilles Deleuze (1925–1995)and John Dewey – that appear at first sight tobe separated by time, place and culture. Thescope of the present paper is necessarilylimited and focuses on one aspect of theproject, namely: the problematics ofsubjectivity, or subject formation, inDeleuze's philosophy. Deleuze's position isestablished as pragmatic by virtue of itssharing the value allotted by Dewey toexperiential and experimental inquiry inphilosophy. By drawing initial parallels with anumber of selected Dewey's excerpts, this paperaims to open up a space for the imaginarydialogue between two philosophical thoughts soas to consider a possibility for applyingDeleuze's philosophy to educational theory andpractice in the context of current debates andin a manner continuous with the Deweyan legacy.The paper concludes by affirming Deleuze'splace in the contemporary scholarship on Dewey.     

The Measurement of Cognitive Complexity and Its Relationship With Political Extremism

Three studies tested the relationship between political extremism and cognitive complexity in an adult sample (N = 135), a sample of students (N = 145), and a sample of political party members (N = 47). According to value pluralism theory, advocates of extreme ideologies exhibit low levels of cognitive complexity. Context theory, in contrast, states that extremists think in a more complex and sophisticated way about politics. In accordance with context theory, significant positive correlations between cognitive complexity and extremist ideology were found in all samples. The results of these studies also revealed weak correlations among the cognitive complexity instruments used in previous research. Problems concerning the measurement of cognitive style and cognitive complexity are discussed.     

Falsification and the protective belt surrounding entity-postulating theories

Meehl’s article is a contradiction. In every area, he recognizes some of what is wrong and then advocates a course that will produce more of the same. He sees the problem with falsification and in essence advocates for its alternative, verification, but falsely claims this strategy is still falsification and is useful when there is a loose link between theories and their auxiliaries and conditions. He acknowledges the proven value of tightening the link between theories and their auxiliaries and conditions, but rejects that course because it does not apply to his preferred theories. Twenty-five years later there is even more “slow progress” to ponder. It is time to dismantle the protective belt surrounding entity-postulating theories that Meehl’s reasoning has helped to create.     

Early Communications in the War Against Terrorism: An Integrative Complexity Analysis

Integrative complexity reflects the degree to which the source of a communication perceives several dimensions and points of view relevant to the topic (differentiation) and the degree to which such characteristics are seen as related to each other (integration). During international crises, bilateral decreases in the integrative complexity of communications frequently precede the outbreak of war; a unilateral decrease reliably precedes surprise strategic attacks. In the current study, complexity was scored in the messages of selected leaders from before to approximately a month after the terrorist attacks of 11 September 2001. Even this limited database replicated some of the complexity patterns found previously, as well as showing some novel characteristics. This was the first application of the method to hostilities other than inter–nation or civil wars.

客体复杂度影响工作记忆可存储的客体数目

采用变化觉察范式,以对侧延迟活动（contralateral delay activity,CDA）的幅值为指标,通过操纵记忆刺激的复杂程度,对视觉工作记忆中可存储的客体数目（即工作记忆容量）问题进行了探讨。结果表明,2个复杂客体条件下的CDA幅值与4个复杂客体条件无显著差异,而4个简单客体条件的CDA幅值显著高于2个简单客体条件,即CDA的幅值受客体复杂度的调节。基于该结果推论：并非视觉工作记忆总能存储4个客体,其可存储的客体数目受客体复杂度影响。
