Effects of prior exposure to the experimental chamber with levers present or absent and variable-time (VT) 60-s water deliveries arranged during one, five, or no 1-hr sessions were examined in rats during a 6-hr response-acquisition session in which presses on one lever produced water delivery immediately or after a 15-s resetting delay, and presses on the other lever canceled scheduled water deliveries. Response acquisition was (a) slower to occur when water deliveries were delayed, (b) most consistent in groups that had received five VT sessions, and (c) impaired by the presence of levers only when there had been five VT sessions and water deliveries were delayed during the acquisition session.  相似文献

Historiography of education is not only a question of construction but also of selection. In 19th century history of education was typically a genre of great educators, mostly male and only marginally female. This construct is influential up to now, at least in popular contexts of educational reasoning. The article discusses in the introductory section problems of selection of names and meanings within history of education, and then three types of historiographical writing that are not only concerned with great educators but have larger Philosophical impact. The first type is Herman Nohls history of German progressive education, the second one is Emile Durkheims history of Higher Education in France, and the third one is George Herbert Meads Movements of Thought in 19th Century. The article compares them and discusses their implications for further development of historical writing in education.  相似文献

A short overview of several saints, including Peter, Paul, John, George, Hilarius, Hubert, and Gaudentius, venerated in Christian tradition as protectors from snake bite, is offered as an introduction to a more substantial debate on the factors determining the choice of protectors in folk medicine, as well as on the possible adjuvant effect of (auto)suggestive therapy obtained by the invocation of saints.  相似文献

Summary  Big History – an integral conception of the past since the Big Bang until today – is a novel subject of cross-disciplinary interest. The concept was construed in the 1980–1990s simultaneously in different countries, after relevant premises had matured in the sciences and humanities.Various versions and traditions of Big History are considered in the article. Particularly, most of the Western authors emphasize the idea of equilibrium, and thus reduce cosmic, biological, and social evolution to the mass-energy processes; the informational parameter involving all mental and spiritual aspects are seen as epiphenomena of material structures” complication that do not play their own role in evolution. In Russian tradition ascending to A. Bogdanov, E. Bauer, I. Prigogine, and E. Jantsch, sustainable non-equilibrium patterns are used. This implies attention to the pan-material sources and evolution of mental capacities and spiritual culture (as basic anti-entropy instruments) and humans” growing intervention in the material processes on Earth and outside it.The non-equilibrium approach in the context of modern control and self-organization theories, alters the portrayal of the past, and still more dramatically, estimation of the civilization’s potential perspectives.  相似文献

The current debate in medical ethics on placebos focuses mainly on their use in health research. Whereas this is certainly an important topic the discussion tends to overlook another longstanding but nevertheless highly relevant question, namely if and how the placebo effect should be employed in clinical practice. This paper describes the way the placebo effect is perceived in modern medicine and offers some historical reflections on how these perceptions have developed; discusses elements of a definition of the placebo effect; and suggests some conditions under which making use of the therapeutic potential of the placebo effect can be ethically acceptable, if not warranted. An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research Today,” held in Warsaw, Poland on 12–13 April, 2003. Nikola Biller-Andorno, MD, PhD, is Assistant Professor in the Dept. of Medical Ethics and History of Medicine, University of Goettingen, Germany. Dr. Biller-Andorno also serves as an ethicist for the World Health Organization (WHO). This paper does not necessarily reflect the views of the World Health Organization.  相似文献

After Ferenczi's death of pernicious anemia in 1933 at the age of 59, Michael Balint became the greatest advocate of his late analyst, teacher, colleague, and friend. He was faced with widespread avoidance, a conspiracy of silence against Ferenczi in the psychoanalytic movement. Ernest Jones, in particular, an analysand of Ferenczi and fellow member of the Secret Committee founded by Freud before World War I, seriously attacked Ferenczi. In the third volume of the Freud biography, Jones alleged that in the last years of his life Ferenczi suffered mental deterioration caused by the pernicious anemia, and that this mental decline was the real cause of Ferenczi's technical experimentations, thereby belittling the importance of Ferenczi's independent work in the last phase of his life. This article answers whether Michael Balint, who later became the literary executor of Ferenczi, was devoted enough in countering the charges that lead to a fifty-year silence on Ferenczi's eminent place in psychoanalysis. Correspondence between Balint and Jones is cited, as are reports of Ferenczi's contemporaries; Balint's efforts are placed within the context of the psychoanalytic rivalries after Freud's death.  相似文献

A thorough understanding of Multiple Sclerosis (MS) is necessary to offer individuals informed options for treatment and planning. To assist in this quest, the following historical analysis examined how MS has been conceived from the 14th century through the early 20th century. Primary sources were consulted whenever possible, and many of the original archival materials were accessed by the first author (MB) during an on-site visit to the Rare Book Room of the New York Academy of Medicine. There is a striking similarity between how MS symptoms have presented throughout history compared with the 21st century. Sensorimotor and cognitive sequelae have been observed in patients since the 1800s. Cognitive symptoms were acknowledged in the 1800s, but disregarded in the early 1900s and were not given recognition again until the latter part of the 20th century. If conceptualizations of MS are inaccurate, patients will not be served well. In contrast to the shared symptomatology across time, early conceptualizations of etiology and treatment choices differed dramatically from today, a genuine reflection of the times in which they were created.  相似文献

Four experiments were conducted with pigeons to assess the experimental conditions necessary for the occurrence of resurgence. The general procedure consisted of the following conditions: Condition 1--reinforcement of key pecking; Condition 2--reinforcement of treadle pressing and concurrent extinction of key pecking; and Condition 3--the resurgence condition wherein resurgence was defined as the recovery of key pecking. In Experiments 1 and 2, the resurgence condition was conventional extinction. The effect of recency on resurgence magnitude was examined in Experiment 1 by manipulating the number of sessions of Condition 2, above. Resurgence was not a function of recency with the parameters used. Repeating the three conditions revealed resurgence to be a repeatable effect in Experiment 2. In Experiment 3, a variable-time schedule was in effect for the resurgence condition. Resurgence was not produced by response-independent food delivery. In Experiment 4, the resurgence condition was a variable-interval schedule for treadle pressing that arranged a lower reinforcement rate than in Condition 2 (92% reduction in reinforcers per minute). Resurgence was lower in magnitude relative to conventional extinction, although resurgence was obtained with 2 out of 3 pigeons. The results are discussed in terms of the variables controlling resurgence and the relations between behavioral history, resurgence, and other forms of response recovery.  相似文献

The year of Thorndike's dissertation on animal intelligence, 1898, may mark the beginning of the field that eventually became known as the experimental analysis of behavior. The dissertation began a major shift in thinking about animal and human learning, provided important methodological innovations, and carried the seeds of later research and theory, particularly by B. F. Skinner. Although Thorndike was an associationist in 1898, the dissertation began the systematic search for fundamental behavioral processes, and laid the foundation for an empirical science of behavior.  相似文献
