Naloxone, haloperidol, and neurotensin suppress ACTH-induced grooming. The suppressive effects of naloxone and of haloperidol on ACTH-induced grooming are observed following subcutaneous as well as intracerebroventricular administration. The suppression of ACTH-induced grooming by these drugs is not accompanied by a change in the relative distribution of grooming elements. From previous data and from the results of the present study it is suggested that the underlying substrate involved in ACTH-induced excessive grooming may differ from that of bombesin-induced grooming. 相似文献

A Monte Carlo study was conducted to investigate the robustness of the assumed error distribution in maximum likelihood estimation models for multidimensional scaling. Data sets generated according to the lognormal, the normal, and the rectangular distribution were analysed with the log-normal error model in Ramsay's MULTISCALE program package. The results show that violations of the assumed error distribution have virtually no effect on the estimated distance parameters. In a comparison among several dimensionality tests, the corrected version of thex 2 test, as proposed by Ramsay, yielded the best results, and turned out to be quite robust against violations of the error model. 相似文献

In §66 ofPhilosophical Investigations Wittgenstein looks for something common to various games and finds only an interconnecting network of resemblances. These are family resemblances. Sympathetic as well as unsympathetic readers have interpreted him as claiming that games form a family in virtue of these resemblances. This assumes Wittgenstein inverted the relation between being a member of a family and bearing family resemblances to others of that family. (The Churchills bear family resemblances to one another because they belong to the same family, they don't belong to the same family because they resemble one another.) A close reading ofInvestigations gives no evidence that Wittgenstein made this mistake. Rather, family resemblances may play a role like the one criteria play for psychological terms. They give excellent but fallible evidence for membership in the extensions of some terms.Don't look only for similarities in order to justify a concept, but also for connexions. The father transmits his name to his son even if the latter is quite unlike him.1

The tradition of anthropological medicine in philosophy of medicine is analyzed in relation to the earlier interest in epistemological issues in medicine around the turn of the century as well as to the current interest in medical ethics. It is argued that there is a continuity between epistemological, anthropological and ethical approaches in philosophy of medicine. Three basic ideas of anthropologically-oriented medicine are discussed: the rejection of Cartesian dualism, the notion of medicine as science of the human person, and the necessity of a comprehensive understanding of disease. Next, it is discussed why the anthropological movement has been superseded by the increasing interest in medical ethics. It is concluded that the present-day moral issues cannot be interpreted and resolved without clarification of the underlying anthropological images. 相似文献

Green solved the problem of least-squares estimation of several criteria subject to the constraint that the estimates have an arbitrary fixed covariance or correlation matrix. In the present paper an omission in Green's proof is discussed and resolved. Furthermore, it is shown that some recently published solutions for estimating oblique factor scores are special cases of Green's solution for the case of fixed covariance matrices. 相似文献

Two hypotheses were contrasted. One posed a positive relationship between mere repeated exposure and preference for stimulus of concern; the other predicted that preference for stimuli would be modulated by their relative novelty and complexity. These hypotheses were tested within the context of a naturalistic play situation in which 40 4- to 5-year-old children were repeatedly exposed to and interacted with play settings differing in complexity. Overt preference for play objects declined with repeated exposure, the rate of decline being inversely determined by the complexity of the play stimuli. Preference for peers, however, increased as a function of repeated exposure, with the amount of increase being an inverse function of the complexity of the external setting. 相似文献

The contemporary philosophy of medicine may be characterized as a continuous struggle with the Cartesian heritage, in order to reach a more satisfying image of man. This paper outlines the influence of Cartesian dualism on the foundations of medicine. The notion of a real distinction between the mental and physical, particularly the mechanistic conception of the human body, made possible the development of the natural sciences as well as scientific medicine, not hampered any longer by the risk of colliding with religion or Church. The Cartesian machine model of man immediately appealed to seventeenth century physicians: Dutch Cartesians (Regius, Craanen) and followers of the iatrophysical school (Santorio, Borelli). Dichotomizing between mind and body, subject and object, self and world, self and other, knower and knowledge is constitutive for modern medicine conceiving itself as a natural science. 相似文献

Previous research has demonstrated that a sequence of tones that is alternated between ears is stretched out in echoic memory, as compared with monaural sequences. Although the stimulus onset asynchronies (SOAs) were the same in the interaural and monaural conditions, the perceptual onset asynchronies (POAs) differed by 24 msec. The present study investigated whether an analogous perceptual phenomenon exists for frequency-alternating tone sequences. It turned out that the POAs of coherent and even of streaming tone sequences were precisely the same as with nonalternating tone sequences. 相似文献
