人类意識的起源和发展

人类意識的起源和发展問題在現代科学中占有重要的地位,哲学的基本問題是意識对存在的关系問題,它如何解决,是唯物主义和唯心主义的根本分界綫。唯物主义者认为物貭是第一性的;意識是第二性的,是物貭长期发展的結果,是派生的。因此,研究人类意識的起源和发展,对馬克思主义哲学是有着重大意义的。 人类意識的起源和发展問題,是心理学的基本理論,它涉及到广泛的科学领域,只有在馬克思主义指导下,心理学联合人类学、考古学、語言学、历史学以及其它許多学科,进行綜合性的研究才能得到解决。现代科学对于这个問題已经积累了相当重要的資料和科学論据。     

COGNITIVE COMPLEXITY MEASURES AND THE RELATIONSHIP OF COGNITIVE COMPLEXITY TO COMMUNICATION

This review assesses the adequacy of several commonly employed cognitive complexity measures on the basis of five criteria: high test-retest reliability with adults, association with chronological age across childhood and adolescence, independence from intelligence and verbal abilities, association with other indices of developed social cognition, and association with measures of developed communicative functioning. Extant research indicates that only one complexity measure—Crockett's Role Category Questionnaire—is satisfactory on all these criteria, whereas Bieri's widely used measure is deficient on most. However, research to date concerning the relationship of cognitive complexity (as assessed by Crockett's measure) to communication has failed to illuminate the specific role played by complexity as opposed to other social-cognitive factors with which it is associated.     

ARMSTRONG AND THE MODAL INVERSION OF DISPOSITIONS

D.M. Armstrong has objected that the dispositionalist theory of laws and properties is modally inverted, for it entails that properties are constituted by relations to non-actual possibilia. I contend that if this objection succeeds against dispositionalism, then Armstrong's nomic necessitation relation is also modally inverted. This shows that at least one of Armstrong's reasons for preferring a nomic necessitation theory is specious.     

CONSCIOUSNESS AND THE MACHINE

Abstract. We consider only the relationship of consciousness to physical reality, whether physical reality is interpreted as the brain, artificial intelligence, or the universe as a whole. The difficulties with starting the analysis with physical reality on the one hand and with consciousness on the other are delineated. We consider how one may derive from the other. Concepts of universal or pure consciousness versus local or ego consciousness are explored with the possibility that consciousness may be physically creative. We examine whether artificial intelligence can possess consciousness as an extension of the interrelationship between consciousness and the brain or material reality.     

THE STRUCTURE OF SCEPTICAL ARGUMENTS

It is nowadays taken for granted that the core radical sceptical arguments all pivot upon the principle that the epistemic operator in question is 'closed' under known entailments. Accordingly, the standard anti-sceptical project now involves either denying closure or retaining closure by amending how one understands other elements of the sceptical argument. However, there are epistemic principles available to the sceptic which are logically weaker than closure but achieve the same result. Accordingly the contemporary debate fails to engage with the sceptical problem in its strongest form.     

笔画复杂性和重复性对笔画和汉字认知的影响

采用笔画识别和词汇决定的方法 ,对汉字笔画认知和笔画在汉字认知中的作用作了考察。实验一探讨了汉字笔画自身的复杂性对笔画认知的影响。结果表明 ,笔画自身的复杂性对笔画认知无显著影响 ,识别简单笔画和识别复杂笔画的反应时与错误率无显著差异。实验二考察了笔画的重复性对汉字认知的影响。结果表明 ,汉字认知中存在笔画重复性效应。笔画重复较多的汉字比笔画较少重复的汉字识别时间短 ,错误率亦低。整个实验结果支持笔画是汉字加工的基本单元的假设     

ON THE LIMITATIONS AND PROMISE OF QUANTUM THEORY FOR COMPREHENSION OF HUMAN KNOWLEDGE AND CONSCIOUSNESS

Abstract. I present a partially historical discussion of the basis of the quantum theory in nonmathematical terms using human knowledge and consciousness as an underlying theme. I show that the philosophical position in both classical and quantum theory is the experimental and mathematical philosophy of Isaac Newton. Because almost all the systems we deal with are multicomponent, we must consider the limitations and openness imposed by thermodynamics on our claims in both classical and quantum treatments. Here the reality of measurement stands in the way of any simple picture but also provides the basis for considerations of free will. Particular care is taken with the concepts of quantum measurement, entanglement, and decoherence because of their importance in the discussion.     

COGNITIVE TUNING AND DIFFERENTIATION OF ARGUMENTS IN COMMUNICATION

In an experiment examining the effects of cognitive tuning and attitudinal position upon individuals’ cognitive differentiation in generating arguments supporting and opposing an attitude issue, 162 undergraduate students were “tuned” either as potential sources (transmission tuning) or potential receivers (reception tuning) of a persuasive communication on one of two issues. They then prepared two lists of arguments, one positive and one negative for one of the attitude issues, after which they completed an attitude measure in both issues. As predicted, the subjects made salient and reported significantly more arguments consistent with than inconsistent with their attitudes toward the issues. More importantly, those persons prepared to function as communication sources generated significantly more arguments consistent with and fewer arguments inconsistent with their attitudes than did subjects expecting to receive persuasive communications on the issues.     

SCIENCE,SPIRITUALITY, AND AYAHUASCA: THE PROBLEM OF CONSCIOUSNESS AND SPIRITUAL ONTOLOGIES IN THE ACADEMY

Ayahuasca is a psychoactive brew from Amazonas, popularized in the last decades in part through transnational religious networks, but also due to interest in exploring spirituality through altered states of consciousness among academic schools and scientific researchers. In this article, the author analyzes the relation between science and religion proposing that the “demarcation problem” between the two arises from the relations among consciousness, intentionality, and spirituality. The analysis starts at the beginning of modern science, continues through the nineteenth century, and then examines the appearance of new schools in psychology and anthropology in the countercultural milieu of the 1960s. The author analyzes the case of ayahuasca against this historical background, first, in the general context of ayahuasca studies in the academic field. Second, he briefly describes three cases from Spain. Finally, he discusses the permeability of science to “spiritual ontologies” from an interdisciplinary perspective, using insights from social and cognitive sciences.     

智力和元认知技能在发现学习中的作用:任务复杂性的影响

采用自编的计算机模拟发现学习任务,以49名大学生为被试,探讨了在简单和复杂发现学习任务中,智力、元认知技能和学习成绩三者之间的关系。结果发现:在简单任务中,三者关系基本符合混合模型;进行过多的元认知活动,并不能提高学习效果。在复杂任务中,智力对学习成绩起主要预测作用。随着任务复杂性的增加,智力对学习的影响也随之变化,符合难度阈限理论的假设。任务复杂性不同时,智力、元认知技能和发现学习成绩之间的关系也不同,在一定程度上验证了难度阈限扩展理论。
