选择性注意在人工语法学习中的作用——回应Eitam，Schul和Hassin(2009)中的两点疑问

从语法规则复杂性（复杂语法vs.简单语法）的角度考察选择性注意在人工语法学习中的必要性,并且比较两种非法序列下的成绩差异来检验被选择忽视的语法规则是否能被习得却未能在测验阶段体现出来。结果表明纵使降低被选择注意的语法的复杂性,被忽视的语法也未被成功习得,只有被选择注意的语法才能被习得;两种非法序列下的正确率无显著差异,即非法序列b所遵循的被忽略的语法未能在分类判断中起作用。选择性注意是语法规则被习得的关键。     

言语工作记忆、句子理解与句法依存关系加工

言语工作记忆在句子理解中作用的机制和性质,是当前认知神经科学研究的一个中心课题。文章首先回顾了与支撑语言理解的工作记忆资源的性质有关的理论争论和实验证据,然后回顾了填充语-空位依存关系加工这一能够揭示言语工作记忆与句子理解之间关系的重要领域,最后简要展望了今后应该进一步研究的几个问题     

复杂性理论及其问题

Complexity theories are on the way to establish a new worldview—processes instead of objects, history and uniqueness of everything instead of repetition and lawlikeness are the elements. These theories from deterministic chaos via the dissipative structures, the theory of catastrophes, self organization and synergetics are mathematical models, connected with a new understanding of science. They are characterized by new fundamental commitments of sciences. But at the same time, they are characterized by epistemic boundaries. During my stay as a visiting professor at Dalian University of Technology in September 2006, I had the opportunity to deliver parts of this paper at North-Eastern University at Shenyang and at Beijing Normal University; a first draft has been presented at the IV. Russian Congress of Philosophy, May 2005, Moscow, and published as congress material as Knowledge and Society, edited by Ilya Kassavine, Moscow: Kanon 2005, 178–189.     

基于关系-表征复杂性模型的数学应用题表征能力测验

基于关系-表征复杂性模型,从每道应用题涉及集合关系的嵌套程度角度事前分析其关系复杂性,编制了难度序列变化的应用题测验,以考察问题表征能力。采用该测验测查了四至七年级共165名学生,考察事前分析的合理性及表征水平随年龄的变化。结果表明:(1)事前分析对两个事后难度指标(错误率和Rasch模型分析的任务难度)的解释率分别为73.7%、78.7%;该测验得分与测查思维水平层次变化的SOLO分类测验上的得分有较高相关(r=0.65)。(2)四年级的应用题表征水平显著低于五、六、七年级,其他三个年级差异不显著;而且随着问题关系复杂性的增加,年级差异增大。这说明基于关系-表征复杂性模型的事前分析是合理的,据此编制的测验能够测查表征水平随年龄的变化。     

认知负荷和控制性注意对工作记忆广度任务成绩的影响

通过stroop干扰实验严格筛选被试,考察了控制性注意能力不同的被试在加工部分认知负荷不同的工作记忆广度任务中的成绩。结果表明：任务复杂性和加工速度对工作记忆广度任务成绩有重要影响,任务越复杂或加工速度越快,被试的工作记忆广度任务成绩越低;在复杂的和加工速度快的工作记忆广度任务中,控制性注意能力高的被试成绩要好于控制性注意能力低的被试,但在简单的和加工速度慢的任务中两者成绩没有显著差异。     

Distinct Neurophysiological Patterns Reflecting Aspects of Syntactic Complexity and Syntactic Repair

Aspects of syntactic complexity and syntactic repair were investigated by comparing the event-related (brain) potentials (ERPs) for sentences of different syntactic complexity to those containing a syntactic violation. Previous research had shown that both aspects of syntactic processing are reflected in a late positivity (P600). Results from the present reading experiment demonstrate, however, that although both processing aspects elicit a late positivity, they are different in distribution. The repair-related positivity preceded by a negativity displayed a centroparietal distribution, whereas the complexity-related positivity showed a frontocentral scalp distribution. These data indicate that the P600 is not a unitary phenomenon. Moreover, the distributional differences strongly suggest that different neural structures underlie the two aspects of processing, namely syntactic repair and syntactic integration difficulties, most evident when processing syntactically complex sentences.     

The concurrent validity and test–retest reliability of a visuospatial working memory task

To determine whether the visuospatial n-back working memory task is a reliable and valid measure of cognitive processes believed to underlie intelligence, this study compared the reaction times and accuracy of performance of 70 participants, with performance on the Multidimensional Aptitude Battery (MAB). Testing was conducted over two sessions separated by 1 week. Participants completed the MAB during the second test session. Moderate test–retest reliability for percentage accuracy scores was found across the four levels of the n-back task, whilst reaction times were highly reliable. Furthermore, participants' performance on the MAB was negatively correlated with accuracy of performance at the easier levels of the n-back task and positively correlated with accuracy of performance at the harder task levels. These findings confirm previous research examining the cognitive basis of intelligence, and suggest that intelligence is the product of faster speed of information processing, as well as superior working memory capacity.     

Paradoxical frames and creative sparks: Enhancing individual creativity through conflict and integration

Across industries, organizations operate in increasingly complex and uncertain environments. To succeed in such environments, organizations require their members to think creatively and integrate conflicting demands. We propose that the adoption of paradoxical frames—mental templates that encourage individuals to recognize and embrace contradictions—increases creativity. In four laboratory studies using different creativity tasks and different manipulations for eliciting paradoxical frames, participants who adopted paradoxical frames were more creative than their counterparts who did not. Our results suggest that the positive influence of paradoxical frames on creativity is due to the paradoxical relationship between task elements and not merely to their joint activation. This paradoxical relationship creates a sense of conflict in individuals and enhances their ability to integrate contradictions, which in turn increases creativity.     

A Completeness Proof for a Logic with an Alternative Necessity Operator

We show the completeness of a Hilbert-style system LK defined by M. Valiev involving the knowledge operator K dedicated to the reasoning with incomplete information. The completeness proof uses a variant of Makinson's canonical model construction. Furthermore we prove that the theoremhood problem for LK is co-NP-complete, using techniques similar to those used to prove that the satisfiability problem for propositional S5 is NP-complete.     

Order,disorder, and the absolute: An experiment in dialogue

The first section of this dialogue is excerpted from an edited conversation between Sean Kelly and the late David Bohm, and focuses on the concepts of order, disorder, and the Absolute. The second section explores these concepts in greater depth, with Bohm maintaining the impossibility of absolute knowledge and the fundamental unintelligibility of the concept of disorder, preferring instead to speak of “orders of infinite degree” which emerge out of an “unknown ground.” Kelly responds by proposing the concept of “absolute knowing” as the cognitive process within which the concepts of order and disorder, the known and the Unknown are seen as dialectically related moments of the Absolute as complex whole. The third section is Edgar Morin's response to the preceding dialogue. He begins by outlining his views on the nature and limits of rationality, maintaining, with Bohm, the superiority of the “negative modality” of speaking about “being” or “reality.” In the second part, however, he proposes the notion of nature as “chaosmos,” which he understands as a creative “dialogic” of order, disorder, and organization.
