问题解决的表征态理论

问题解决的表征态理论(简称RST)认为问题解决就是问题的表征态连续、非线性的变化的过程,其中存在数据驱动和概念驱动两种方式。在问题表征态变化的过程中,问题解决者所掌握的专业知识起着重要的作用,它是问题解决者对问题情境信息进行同化的基础,也是对问题结构进行心理建构的基础。RST的假设及其推论在中学生物理问题解决过程中得到检验。     

列斐伏尔与现代世界的日常生活批判

列斐伏尔的《现代世界的日常生活批判》一书,是他从马克思哲学观点出发．批判现代消费社会的一本重要著作。在这本书中,列斐伏尔指出：现代社会是一个被控消费的官僚社会,这是一个风格消失、意义走向零度化的社会,日常生活世界成为资本主义社会意识形态的共谋者。从日常生活批判出发,以文化革命日常生活中的异化现象,构成了列斐伏尔的理论主题。     

Intuitive physics and cognitive algebra: A review

IntroductionIntuitive physics explores how people without a formal instruction in physics intuitively understand physical phenomena. After a general overview of the topics of current research in intuitive physics and a discussion of current debates, this paper provides an introduction to Information Integration Theory (IIT).ObjectiveBy means of examples, it is shown how IIT can be used to directly compare the algebraic structure of physical laws and the algebraic structure of cognitive representations of these laws.MethodThe review considers about 40 years of research on the application of IIT in the field of intuitive physics. Occasionally, reference is also made to intuitive physics studies outside this theoretical framework.ResultsThe reviewed studies highlight four main factors that affect the degree of consistency between physical laws and cognitive algebraic laws: the participants’ age, their familiarity with the event under study, the type of task, and possible learning processes.ConclusionThe last part of the article discusses the implications of the results of the reviewed studies for the two main current hypotheses on the nature of intuitive physics, namely, that intuitive physics may be based on sub-optimal heuristics or may be based on the internalization of physical laws.     

Toward an Integrative Model of Creativity and Personality: Theoretical Suggestions and Preliminary Empirical Testing

The present work proposes an integrative model of creativity that includes personality traits and cognitive processes. This model hypothesizes that three high‐order personality factors predict two main process factors, which in turn predict intensity and achievement of creative activities. The personality factors are: Plasticity (high openness, extraversion, energy, and inspiration), Divergence (low agreeableness and conscientiousness, high non‐conformity and impulsivity), and Convergence (high ambition, precision, persistence, and critical sense). The process factors are Generation (idea production and originality) and Selection (idea evaluation and formalization). We hypothesized and found that: (a) Plasticity and Divergence predict positively Generation, (b) Convergence predicts positively Selection, (c) Generation, Selection, and their interaction predict positively both intensity and achievement of everyday creative activities.     

Freedom and the psychoanalytic ontology of quantum physics

Jung's paper ‘Synchronicity – an acausal connecting principle’, defining the phenomenon as a ‘meaningful’ coincidence depending on archetypal activation, was published in 1952, together with a conceptually related piece by physicist and Nobel Laureate Wolfgang Pauli entitled, ‘The influence of archetypal ideas on the scientific theories of Kepler’. Slavoj ?i?ek, in The Indivisible Remainder: On Schelling and Related Matters, suggests that, in contrast to any notion of a ‘pre‐modern Jungian harmony’, the main lesson of quantum physics was that not only was the psychoanalytic, empty subject of the signifier constitutively out‐of‐joint with respect to the world, but that the Real in itself was already incomplete, out‐of‐joint, ‘not‐all’. Yet while ?i?ek frequently tries to separate Jung from his own ontology, this paper shows that his ontology is not as different as he suggests. Consistent with our earlier publications on Jung and Zizek, a closer investigation reveals an underlying congruence of both of their approaches. In this paper we show that this affinity lies in the rejection by both Jung and ?i?ek of the ideology of reductive materialism, a rejection that demonstrably draws on quantum physics in similar ways. While Jung posits an inherently meaningful universe, ?i?ek attempts to salvage the freedom of human subjectivity by opposing his Lacanian ‘dialectical materialism’ to reductive materialism.     

Everyday Problem Solving and Emotion: An Adult Developmental Perspective

ABSTRACT— Despite cognitive declines that occur with aging, older adults solve emotionally salient and interpersonal problems in more effective ways than young adults do. I review evidence suggesting that older adults (a) tailor their strategies to the contextual features of the problem and (b) effectively use a combination of instrumental and emotion-regulation strategies. I identify factors of problem-solving contexts that affect what types of problem-solving strategies will be effective. Finally, I discuss how this identification of factors affects what we know about developmental differences in everyday problem-solving competence.     

Time to completion of web-based physics problems with tutoring

We studied students performing a complex learning task, that of solving multipart physics problems with interactive tutoring on the web. We extracted the rate of completion and fraction completed as a function of time on task by retrospectively analyzing the log of student-tutor interactions. There was a spontaneous division of students into three groups, the central (and largest) group (about 65% of the students) being those who solved the problem in real time after multiple interactions with the tutorial program (primarily receiving feedback to submitted wrong answers and requesting hints). This group displayed a sigmoidal fraction-completed curve as a function of logarithmic time. The sigmoidal shape is qualitatively flatter for problems that do not include hints and wrong-answer responses. We argue that the group of students who respond quickly (about 10% of the students) is obtaining the answer from some outside source. The third group (about 25% of the students) represents those who interrupt their solution, presumably to work offline or to obtain outside help.     

The presumption of movement

The conceptualisation of movement has always been problematical for Western thought, ever since Parmenides declared our incapacity to conceptualise the plurality of change because our self-identical thought can only know an identical being. Exploiting this peculiar feature and constraint on our thought, Zeno of Elea devised his famous paradoxes of movement in which he shows that the passage from a position to movement cannot be conceptualised. In this paper, I argue that this same constraint is at the root of our incapacity to conceptualise the unseen movement at the micro-level and that the aporetic idea of super-position far from opening the gate on a deeper reality is a symptomatic word for this lack of understanding.

Against digital ontology

The paper argues that digital ontology (the ultimate nature of reality is digital, and the universe is a computational system equivalent to a Turing Machine) should be carefully distinguished from informational ontology (the ultimate nature of reality is structural), in order to abandon the former and retain only the latter as a promising line of research. Digital vs. analogue is a Boolean dichotomy typical of our computational paradigm, but digital and analogue are only “modes of presentation” of Being (to paraphrase Kant), that is, ways in which reality is experienced or conceptualised by an epistemic agent at a given level of abstraction. A preferable alternative is provided by an informational approach to structural realism, according to which knowledge of the world is knowledge of its structures. The most reasonable ontological commitment turns out to be in favour of an interpretation of reality as the totality of structures dynamically interacting with each other. The paper is the first part (the pars destruens) of a two-part piece of research. The pars construens, entitled “A Defence of Informational Structural Realism”, is developed in a separate article, also published in this journal.     

Joseph Rotblat and the Moral Responsibilities of the Scientist

Professor Sir Joseph Rotblat was one of the most distinguished scientists and peace campaigners of the post second world war period. He made significant contributions to nuclear physics and worked on the development of the atomic bomb. He then became one of the world’s leading researchers into the biological effects of radiation. His life from the early 1950s until his death in August 2005 was devoted to the abolition of nuclear weapons and peace. For this he was awarded the Nobel Peace Prize, together with Pugwash Conferences on Science and World Affairs (that he helped found) in 1995. His work in this area ranked with that of Albert Einstein and Bertrand Russell and this article is an attempt to summarise his life, achievements, but in particular outline his views on the moral responsibilities of the scientist. He is a towering intellectual figure and his contributions to mankind should be better known and more widely understood.
