Unification of models for choice between delayed reinforcers.   总被引:2,自引:2,他引:0       下载免费PDF全文
Two models for choice between delayed reinforcers, Fantino's delay-reduction theory and Killeen's incentive theory, are reviewed. Incentive theory is amended to incorporate the effects of arousal on alternate types of behavior that might block the reinforcement of the target behavior. This amended version is shown to differ from the delay-reduction theory in a term that is an exponential in incentive theory and a difference in delay-reduction theory. A power series approximation to the exponential generates a model that is formally identical with delay-reduction theory. Correlations between delay-reduction theory and the amended incentive theory show excellent congruence over a range of experimental conditions. Although the assumptions that gave rise to delay-reduction theory and incentive theory remain different and testable, the models deriving from the theories are unlikely to be discriminable by parametric experimental tests. This congruence of the models is recognized by naming the common model the delayed reinforcement model, which is then compared with other models of choice such as Killeen and Fetterman's (1988) behavioral theory of timing, Mazur's (1984) equivalence rule, and Vaughan's (1985) melioration theory.  相似文献

This article offers a broad overview of transformative learning theory focusing primarily on the rational and affective dimensions of the theory. As a comprehensive theory of adult learning, transformative learning theory seeks to articulate a process by which persons make meaning of their experiences and their lives. The theory provides a solid educational basis for the learning process in CPE. A list of major sources in the theory is included.  相似文献

In two articles the controversial situation within contemporary psychoanalytic theory is discussed with reference to both the form and content of the theory. In the first article some areas of theoretical conflict between traditional drive theory, on the one hand, and object relations theory, self theory, and ego theory, on the other, are surveyed. It is concluded that inconsistency and ambiguity seem so penetrating that one can hardly speak of a unified theory of psychoanalysis at present. This seems to be a new situation in the history of psychoanalysis. A main issue of disagreement is that between drive theory and object relations theory concerning the nature of human motivation. In order to bridge the theoretical gap between the two positions, it seems necessary for psychoanalysis to disclaim the monolithic status of the drives and to adopt a broad theory of motivation where drives are only one contribution among several types of motivating forces. In the second article some lines of advance in psychoanalytic theory are discussed.  相似文献

当代医学道德发展的走向理应是健康道德,后医学伦理学时代理应是健康伦理学。建设健康伦理学需要搭成一个基本理论架构。其组成至少应该有“九大理论”,即生命神圣论、生命质量论、生命价值论,医学人本论、医学功利论、医学公正论,医者美德论、医者义务(患者权利)论、医患和谐论。其间,按顺序由每三论构成一个“统一论”,将第一个“统一论”作为立论前提,将第二个“统一论”作为直接依据,将第三个“统一论”作为应用指南,如此,才能由三个“统一论”共同地更好地阐释全部健康伦理学问题。  相似文献

This paper contains a formal theory of functional parthood. Since the relation of functional parthood is defined here by means of the notion of design, the theory of functional parthood turns out to be a theory of design. The formal theory of design I defend here is a result of introducing a number of constraints that are to express the rational aspects of designing practice. The ontological background for the theory is provided by a conception of states of affairs. The theory is accompanied with a formal model. I prove that the theory is sound and complete with respect to this model.  相似文献

The evolutionary theory of behavior dynamics is a complexity theory that instantiates the Darwinian principles of selection, reproduction, and mutation in a genetic algorithm. The algorithm is used to animate artificial organisms that behave continuously in time and can be placed in any experimental environment. The present paper is an update on the status of the theory. It includes a summary of the evidence supporting the theory, a list of the theory's untested predictions, and a discussion of how the algorithmic operations of the theory may correspond to material reality. Based on the evidence reviewed here, the evolutionary theory appears to be a strong candidate for a comprehensive theory of adaptive behavior.  相似文献

This paper provides an overview of theory in religion, aging, and health. It offers both a primer on theory and a roadmap for researchers. Four “tenses” of theory are described—distinct ways that theory comes into play in this field: grand theory, mid-range theory, use of theoretical models, and positing of constructs which mediate or moderate putative religious effects. Examples are given of both explicit and implicit uses of theory. Sources of theory for this field are then identified, emphasizing perspectives of sociologists and psychologists, and discussion is given to limitations of theory. Finally, reflections are offered as to why theory matters.  相似文献

This paper considers the current fragmentation of psychoanalytic theory as a result of the illusorily close association of practice and theory. The author argues that the politically motivated assertion of a direct connection between theory and practice should be set aside and that practice should be liberated from theory, permitting theory to evolve in the context of radically modified patterns of practice. If theory were decoupled from practice, technique might progress on purely pragmatic grounds, on the basis of what is seen to work. Psychoanalytic theory of mental function could then follow practice, integrating what is newly discovered through innovative methods of clinical work. Such a pragmatic, principally action-oriented use of theory would bring psychoanalysis more in line with modern, postempirical views of science.  相似文献

The paper reviews and discusses a number of issues relating to the use of computer technology to assist the process of assessing psychologically relevant variables — computer-assisted diagnostics. A definition of computer-assisted diagnostics is given and theoretical developments are discussed. The paper emphasizes the need to consider theoretical issues relating to a number of domains: theory of content, test theory, human—computer interaction, programming theory, instructional theory, normative theory and situation theory. The paper concludes with a view of the current situation and future perspectives, and describes some important ethical issues.  相似文献

Some mathematicians and philosophers contend that set theory plays a foundational role in mathematics. However, the development of category theory during the second half of the twentieth century has encouraged the view that this theory can provide a structuralist alternative to set-theoretical foundations. Against this tendency, criticisms have been made that category theory depends on set-theoretical notions and, because of this, category theory fails to show that set-theoretical foundations are dispensable. The goal of this paper is to show that these criticisms are misguided by arguing that category theory is entirely autonomous from set theory.  相似文献

Summary The distinction is drawn between the metatheoretical commitments of Gestalt theory and their instantiations in explicit theory. It is argued that the metatheoretical commitments of Gestalt theory reflect important insights which might have served as the foundation of a theory of perception that avoids a number of the major difficulties associated with constructivism and the theory of direct perception. For this reason rehabilitation of the reputation of Gestalt theory is urged. In the concluding section certain similarities between the foundational premises of Gestalt theory and parallel distributed processing approaches are noted.The contents of this paper were presented initially at a symposium on perceptual theory in honor of Irvin Rock which convened in Washington, DC, on the occasion of the 1986 meetings of the American Psychological Association  相似文献

Over the 50 years since Donald Campbell advanced his Darwinian theory of creative thought, now better known as the blind variation, selective retention (BVSR) theory of creativity, a considerable literature has evolved, involving both support and opposition to the theory. The most prolific support of BVSR theory is due to Dean Keith Simonton. In response to a detailed exposition by Simonton of BVSR theory, a set of cognitive-historical case studies to refute it was presented by Dasgupta; this, in turn, had elicited a response from Simonton. Very recently, Simonton presented an updated version of the theory, which will be called here Simonton's BVSR theory. This article offers two detailed cognitive-historical case studies of actual episodes of technological creativity to challenge and contest BVSR theory as a general theory of creativity.  相似文献

该文对Braine提出的在推理心理学研究领域占居重要地位的“心理逻辑理论”做了综合述评。“心理逻辑理论”主要包括三方面内容:构成“心理逻辑理论”基础的一组推理规则图式、将推理规则图式应用于推理过程的推理方案、实际应用意义。Braine认为他和他的同事于1984年设计并实施的以“自然推理系统”所含各推理规则为实验材料的实验结果支持该理论的基本观点。  相似文献

In the contemporary biomedical literature, every disease is considered genetic. This extension of the concept of genetic disease is usually interpreted either in a trivial or genocentrist sense, but it is never taken seriously as the expression of a genetic theory of disease. However, a group of French researchers defend the idea of a genetic theory of infectious diseases. By identifying four common genetic mechanisms (Mendelian predisposition to multiple infections, Mendelian predisposition to one infection, and major gene and polygenic predispositions), they attempt to unify infectious diseases from a genetic point of view. In this article, I analyze this explicit example of a genetic theory, which relies on mechanisms and is applied only to a specific category of diseases, what we call “a regional genetic theory.” I have three aims: to prove that a genetic theory of disease can be devoid of genocentrism, to consider the possibility of a genetic theory applied to every disease, and to introduce two hypotheses about the form that such a genetic theory could take by distinguishing between a genetic theory of diseases and a genetic theory of Disease. Finally, I suggest that network medicine could be an interesting framework for a genetic theory of Disease.  相似文献

I argue in this paper that anyone who accepts the ontology of scientific realism can only accept a pragmatic theory of truth, i.e., a theory on which truth is what it is epistemically right to believe. But the combination of realism with such a theory of truth is a form of internal realism; therefore, a scientific realist should be an internal realist. The strategy of the paper is to argue that there is no adequate semantic or correspondence theory of truth compatible with a realist ontology, that a redundancy theory cannot account for the value of truth, and that the only kind of truth theory which can account for the value of truth, and is compatible with a realist ontology, is a pragmatic theory. The kind of truth theory I wish to defend is objective and naturalistic, and the ontology is realistic. My position is, therefore, one of objective, naturalistic realism.  相似文献

After a discussion of the impact of psychoanalysis on psychological thinking about personality theory and the changes that have been taking place within psychoanalytic theory about women, eight criteria arising out of feminist therapy theory are stated. These criteria represent suggested minimum conditions that a woman-based theory of female development and personality needs to fulfill. Freudian theory, current psychoanalytic theory, and several feminist theories are then evaluated in light of the stated criteria. The author concludes that feminists have arrived at some degree of general agreement about personality theory, although they have often arrived at their specific approaches via diverse theoretical routes.  相似文献

弗完全理论通过限制排中律的使用,弱化经典逻辑,采用非经典的三值语言来处理语义悖论,最终使得形式语言能够一致地包含自身的真谓词。文中我们讨论了弗完全理论的两种基本形式——基础的弗完全理论和高级的弗完全理论。基础的弗完全理论引入了"真值空缺"的思想,认为句子除了真假之外还有"既不真也不假"的第三值,像说谎者这样的语义悖论语句就落在真假之空缺中,该理论借助于对不动点的归纳构造过程证明了形式语言中真谓词的存在性。高级弗完全理论在前者的基础上引入一个适当的条件句,定义了一个"更强的真",发展出了既满足真的素朴模式又具有不动点解释的、一致的高级弗完全理论。  相似文献

In the preceding article it was argued that control theory is not a useful paradigm for understanding work motivation. In doing so, three primary criticisms were presented: (a) that control theory, as originally formulated, does not adequately describe human behavior, (b) that modifications of control theory to describe human behavior have not been successful, and (c) that the use of logical deductions to develop a control theory model of work motivation is less efficacious than a grounded theory approach. In this reply, it will be shown that (a) the first criticism is not incorrect but is an inappropriate basis for criticism, (b) statements regarding modified control theory models are either inaccurate or premature, and (c) both inductive and deductive reasoning play an important role in theory development. In addressing these issues and in discussing the distinct advantages of current control theory models it will be shown that control theory does provide a viable paradigm for understanding work motivation.Thanks to John R. Hollenbeck for his helpful comments on this paper.  相似文献

The theory of Wahdat al-Wujūd, or as it is called in English the Oneness of Being, is the core idea of Sufism. The founder of this theory is Ibn ‘Arabī. There are contradictions in Ibn ‘Arabī’s theory of the Oneness of Being. The most important one, which is my main concern in this essay, occurs in his explanation of the relation between Being, which is, according to him, the only real being, and other beings. According to Ibn ‘Arabī, Being is identical and also non-identical with beings. Different philosophers, through hundreds of years, tried to dissolve such contradictions, by proposing consistent readings of Ibn ‘Arabī’s theory of the Oneness of Being. I will not follow this path. Instead, I take the theory of the Oneness of Being to be a dialetheic one, that is, according to this theory there are true contradictions. Thus, I claim that one can have a paraconsistent semantics of the theory of the Oneness of Being. To do so, I appeal to Graham Priest’s Gluon theory. Gluon theory concerns the problem of unity, that is, what makes the plurality of an object’s parts into a whole? I give a translation of the theory of the Oneness of Being into Gluon theory, and show how Gluon theory explains the theory of the Oneness of Being.  相似文献

传统中国哲学中的阴阳论一直是学界所关注的一个焦点,但对于该体系所具备确切内涵的各方面、以及由其所结成的整个架构的整体理论性质,却很少有人能深入体察。本文通过对《周易》阴阳论的细致分析,提出该理论作为一种形而上学宇宙论,实则是一个内在含括生命论、差异论与秩序论等三个主要方面,并以其中生命论为根基也是最终目的的层级结构。  相似文献
