In three experiments, a rat's lever presses could postpone timeouts from food pellets delivered on response-independent schedules. In Experiment 1, the pellets were delivered at variable-time (VT) rates ranging from VT 0.5 to VT 8 min. Experiment 2 replicated the VT 1 min and VT 8 min conditions of Experiment 1 with new subjects. Finally, subjects in Experiment 3 could postpone timeouts from delivery of pellets that differed in quality rather than quantity (unsweetened versus sweetened pellets). In general, response rates and success in avoiding increased as a function of the rate and quality of the pellets. Also, performance efficiency increased as the experiments progressed, that is, the avoidance response occurred later and later in the response-timeout interval. The results support the conclusion that timeout from reinforcement has functional properties similar to those of more commonly studied aversive stimuli (e.g., shock).  相似文献

Zuidas is a new city centre, which is emerging in the outskirts of Amsterdam. The ambitious project of developing a new international city centre has been carefully planned as the Netherlands has a strong and meticulous tradition for urban planning. The planning has however not only encompassed traditional urban planning aspects such as infrastructure, environmental factors and aesthetics, but has also dealt with the design of urban experiences. Through an introduction of the framework of the structure of experiences, this article examines how urban experiences can be understood and analysed, and deals with how urban experiences can be designed through careful consideration of how experiences are constituted. Taking the psychological structure of experiences into account when designing urbanity is not only interesting, but also highly relevant as Zuidas is competing with other international venues such as La Défense, the Docklands and Potsdamer Platz.  相似文献

Abstract: The reason Descartes cites for invoking the demon argument in addition to the dream argument is that the demon argument is intended to broaden the scope of Descartes' scepticism, to subsume additional beliefs under it. I present an additional, unfamiliar reason. There is, I argue, an important difference between the two sceptical arguments. It pertains not to their scope, but to their “depth”, to the kind of scepticism they are capable of inducing.  相似文献

In a laboratory simulation, a single-subject design was used to examine the effects of two types of social influence on children's eyewitness testimony, which has not been the subject of systematic behavioral analyses. This study replicates and extends findings from group-comparison studies, and shows that a topic of pressing social importance is amenable to analysis at the individual level, and therefore, potentially, to a behavioral analysis.  相似文献

The author attempts to integrate several perspectives within the field of infant observation that reflect the analyst's personal experience as a clinician, as a professor at the analytic institute and as a researcher in the field of psychoanalysis. Can infant observation contribute to analytic technique, theory and training? If so, what would be the nature of such contribution? To answer these questions, the author reviews the literature on infant observation from Freud to the present, highlighting Latin American contributions to this subject. She makes reference to the role of technological innovations, which have allowed videotaping, repeated observations, temporal segmentation and computerized programs, thus giving rise to microanalytic research. This discussion prompts the question about the contributions made by systematic research to clinical practice. To tackle this question, the author presents both a clinical vignette taken from her personal experience, and the current debate on this subject as it appears in the work of Daniel Stern and André Green. Finally, she presents some conclusions that are part of an ongoing debate in the psychoanalytic field.  相似文献

Recent controversies surrounding the discernment of design in the natural world are an indication of a pervasive disquiet among believers. Can God as creator/sustainer of creation be reconcilable with the belief that God's work is indiscernible behind secondary evolutionary causes? Christian piety requires that the order experienced in the natural world be evidence of God's love and existence. Theistic evolutionary models rarely examine this matter, assuming that God is indiscernible in the processes and order of the world because only secondary causes can be examined. This leaves antievolutionary perspectives to interpret and address the problem of seeing God in the world. I examine these issues in order to gain more credibility for the religious longing to discern God in nature while at the same time affirming the indubitable truth of an evolutionary history. I argue that God's trinitarian nature, hiddenness, and incarnation give us reason to believe that God's presence in the natural world will be discernible, but only within the natural processes, and thereby only in an obscured fashion. I also argue that newer understandings of evolutionary mechanisms are more consistent with theological appropriation than are strictly Darwinian ones.  相似文献

Abstract. Current teleology in Western biology, philosophy, and theology draws on resources from four main Western philosophers. (1) Plato's Timaeus shows how to interpret the universe as the handiwork of a purposive Creator who subordinates secondary, necessary, causes to primary, intelligent, causes. (2) Aristotle's Physics sets forth purpose as implicit in the nature of things. Purposes of different sorts inhere in different types of being, and everything has a natural function. Living things grow to actualize the potentials of the goal whose principle they bear within themselves. (3) Kant's Critique of Judgment denies that purpose is anything that human beings can know, strictly speaking. Nevertheless, purpose is a concept we must use to make sense of biological systems. (4) Hegel's Philosophy of Nature articulates organic systems as dialectically including and transcending mechanical and chemical systems. Teleological themes persist, in different ways, in contemporary discussions; I consider two lines of criticism of traditional teleology—by Richard Dawkins and Stephen Jay Gould—and one line that continues traditional teleology in an updated way—by Holmes Rolston, III.  相似文献

Kindergarten Ss were presented with 16 pictorial items in four category sets or a partially random ordem with one item from each category composing the four presentation sets. The pictures were presented either on conceptually related background pictures or on white backgrounds. The categorically grouped presentation facilitated free recall performance, both in terms of number of items recalled and the speed with which the items were recalled, and increased the amount of clustering in recall. Categorical clustering in recall was associated with shorter within- than between-category intervals and for those Ss who recalled items from each of four categories successively, the over-all temporal pattern in recall closely approximated that found with adults. No background effects were found.  相似文献

According to a common thesis about normative reasons for action, you have a reason to perform a given action only if you can act for that reason. This thesis has long had broad appeal and is intended to capture the practical character of practical reasons. I’ll call it the ‘Practicality Thesis’. Recently, however, various writers have developed subtly different objections to it, each designed to show that there can be actions you have a reason to perform even though you could not act for that reason – because, were you aware of the reason-giving facts in the ways needed to act for the reason, it would no longer be a reason for you to so act. This article defends the Practicality Thesis against such objections. It considers some extant defences but shows that these are inadequate. It then advances an alternative approach intended to counter any structurally similar objection.  相似文献
