A central component of Beck et al.’s (1979) cognitive theory of depression is faulty information processing reflected by so-called cognitive errors. These cognitive errors are the reason why depressed individuals systematically misinterpret the significance of events in a negative way. They are usually assessed with the application of the Cognitive Error Questionnaire (CEQ). This study examines the psychometric properties and factor structure of the German version of the CEQ in a sample of 796 volunteers at a German university. Results confirmed that the German CEQ has satisfactory to very good psychometric properties, like the American original. Confirmatory factor analyses demonstrated that a hierarchical four-factor model with four subscales and 1 s order factor fits the data best. Therefore, besides using the German CEQ in studies with German-speaking samples, the similarities in psychometric properties of the American and German CEQ allow for cross-cultural studies.  相似文献

论进化心理学的“心理机制”   总被引:1,自引:0,他引:1  
“心理机制”是进化心理学的核心概念。对这一概念的理解直接影响着对整个进化心理学理论的理解。该文尝试从心理学其它相关学科的角度,对这一概念的性质进行充分的解读与分析,同时也指出进化心理学“心理机制”理论之明显误区,并在此基础上对进化心理学价值之所在给予充分的彰显。  相似文献

An investigation of Proclus' logic of the syllogistic and of negations in the Elements of Theology, On the Parmenides, and Platonic Theology. It is shown that Proclus employs interpretations over a linear semantic structure with operators for scalar negations (hypernegation/alpha-intensivum and privative negation). A natural deduction system for scalar negations and the classical syllogistic (as reconstructed by Corcoran and Smiley) is shown to be sound and complete for the non-Boolean linear structures. It is explained how Proclus' syllogistic presupposes converting the tree of genera and species from Plato's diairesis into the Neoplatonic linear hierarchy of Being by use of scalar hyper and privative negations.  相似文献

标量计时模型为人类时间知觉的研究提供了理论框架和研究范式, 它采用信息加工的观点, 包含时钟、记忆和决策三个阶段。时间二分任务是在标量计时模型的框架下研究时间知觉和加工的理想范式。它要求被试对时距进行与标量计时模型相对应的多阶段操作, 包含了时间知觉所涉及的各个过程, 能有效测量主观时距和时间敏感性的变化。通过这个范式, 研究者发现, 除了任务参数, 年龄和疾病都会影响人的主观时距和/或时间敏感性。这些时间二分任务的实验结果促进了标量计时模型的发展, 最近提出的两阶段决策模型和差别模型分别以不同的方式对标量计时模型进行了修正, 并解释了参数设置的影响和计时的个体差异。  相似文献

在存在论的意义上,《管子》中的“道”、“德”是被作为重要的哲学范畴运用的,指生命产生的根源和生命存在的内在根据,二者是一体共在的关系。《管子》的“道”、“德”论揭示了人与万物在自然本性层面上的内在一体性和生态伦理的存在论维度,启示我们生态伦理应超越人与自然的外在关系,建立于人与自然内在关系的基础上。  相似文献

Coecke  Bob 《Studia Logica》2002,71(1):47-56
In Coecke (2002) we proposed the intuitionistic or disjunctive representation of quantum logic, i.e., a representation of the property lattice of physical systems as a complete Heyting algebra of logical propositions on these properties, where this complete Heyting algebra goes equipped with an additional operation, the operational resolution, which identifies the properties within the logic of propositions. This representation has an important application towards dynamic quantum logic, namely in describing the temporal indeterministic propagation of actual properties of physical systems. This paper can as such by conceived as an addendum to Quantum Logic in Intuitionistic Perspective that discusses spin-off and thus provides an additional motivation. We derive a quantaloidal semantics for dynamic disjunctive quantum logic and illustrate it for the particular case of a perfect (quantum) measurement.  相似文献

This paper focuses on the question of whether DNA patents help or hinder scientific discovery and innovation. While DNA patents create a wide variety of possible benefits and harms for science and technology, the evidence we have at this point in time supports the conclusion that they will probably promote rather than hamper scientific discovery and innovation. However, since DNA patenting is a relatively recent phenomena and the biotechnology industry is in its infancy, we should continue to gather evidence about the effects of DNA patenting on scientific innovation and discovery as well the economic, social, and legal conditions relating to intellectual property in biotechnology. We should give the free market, the courts, researchers, and patent offices a chance to settle issues related to innovation and discovery, before we seek legislative remedies, since new laws proposed at this point would lack adequate foresight and could do more harm than good. However, we should be open to new laws or regulations on DNA patents if they are required to in order to deal with some of the biases and limitations of the free market.  相似文献
