Although the literature on reinforcement in behavioral psychology is extensive, few studies have examined the derived transformation of reinforcing functions in accordance with equivalence classes, and no published research has yet examined the derived transformation of consequential functions in accordance with nonequivalence relations. In the present study, which consisted of four experiments, the basic preparation was as follows. First, an arbitrary stimulus, B2, was established as a conditioned punisher, using direct stimulus pairing. Following nonarbitrary relational training, designed to establish SAME and OPPOSITE contextual cues, subjects were exposed to arbitrary relational training using these contextual cues to establish A1 as the same as B1 and C1, and as opposite to B2 and C2. Subsequently, C2 (based on its Same relation with B2) functioned as a punisher and C1 (based on its Opposite relation with B2) functioned as a reinforcer in a simultaneous discrimination task. Critically, the C1 stimulus acquired reinforcing functions, based on the derived relation of Opposite, although no such function had actually been established for any member of the network. Furthermore, these effects were observed across ABA reversals in the baseline contingencies.  相似文献

Humans are a part of the complex system including both natural and cultural-technological environment. Evolution of this system included self-amplifying feedbacks that lead to the appearance of human conscious mind. We describe the current state of the understanding of human brain evolution that stresses neurohormonal and biochemical changes rather than simple increase of anatomical substrate for the mind. It follows that human brain is strongly influenced by the state of the body and may operate at various levels of consciousness depending on its biochemical environment created by ingestion of various substances and by specific physical activities. Through the study of the widespread phenomenon of shamanism that uses mind-altering practices we argue that altered states of consciousness and non-local minds are not only real phenomena, but that they are products of natural evolution, valuable for human survival and development. Consideration of altered states of consciousness and broadening of the framework for understanding brain function beyond mechanistic interpretations is necessary to further develop human adaptations and provide a better way of fitting humans as parts of the interconnected system into the global and universal patterns.  相似文献

Abstract. Borowitz's book is primarily a systematic response by a liberal Jewish theologian to his perceived challenges from rationalism on one hand and postmodernism on the other. It is within this context that Borowitz discusses issues of the relationship between modern science and Judaism. The first part of this essay is a summary of Borowitz's book. Here I locate Borowitz's place in the general discipline of Jewish philosophy and theology. The second part of the paper is a critique of Borowitz's discussion of postmodernism and liberalism. It is in this concluding section that the issues raised by contemporary science for Jewish religious thought are discussed.  相似文献

Abstract: Human rights developed in response to specific violations of human dignity, and can therefore be conceived as specifications of human dignity, their moral source. This internal relationship explains the moral content and moreover the distinguishing feature of human rights: they are designed for an effective implementation of the core moral values of an egalitarian universalism in terms of coercive law. This essay is an attempt to explain this moral‐legal Janus face of human rights through the mediating role of the concept of human dignity. This concept is due to a remarkable generalization of the particularistic meanings of those “dignities” that once were attached to specific honorific functions and memberships. In spite of its abstract meaning, “human dignity” still retains from its particularistic precursor concepts the connotation of depending on the social recognition of a status—in this case, the status of democratic citizenship. Only membership in a constitutional political community can protect, by granting equal rights, the equal human dignity of everybody.  相似文献

The concept of children as researchers has gained credence in response to changing perspectives on their status in society, recognition of their role as consumers and increased attention to children’s rights. While this has led to greater involvement of children as participant and co-researchers, research led by children—research they design, carry out and disseminate themselves with adult support rather than adult management—is still relatively rare. Children designing and leading their own research opens up new protagonist frontiers. Children are party to the subculture of childhood which gives them a unique “insider” perspective critical to our understanding of their worlds. Child-to-child enquiry generates different data from adult-to-child enquiry because children observe with different eyes, ask different questions and communicate in fundamentally different ways. This paper explores some of the issues in empowering children as active researchers and draws on theory relating to participation, empowerment, voice and emancipation. Its primary focus is to celebrate and value children’s own research and includes the full text of an original research study by an 11-year-old girl.  相似文献

In contemporary moral and political philosophy, there are two leading approaches to the justification of rights. These could be broadly identified as deontological theories and consequential theories. These two schools of theories each have their own strengths and weakness, while there is also a third contractual approach that is under represented. Because Rawls' and Scanlon's well-known contractual theories are designed for purposes other than the justification of rights, the purpose of this paper is to establish a principle of rights on the basis of Rawls' justification device of the "original position." First, it supplies a criterion based on human conduct or action. Second, based on this account of human conduct, different types of relationships are constructed and presented to the parties in the "original position." Third, it will show that the parties in the "original position" would choose one of these relationships as the principle of rights. Finally, Rawls' first principle of justice will be reformulated. The procedure of choosing a principle of rights in this paper could also be viewed as a demonstration that, when properly situated and motivated, human beings exhibit their potential as rational beings.  相似文献
