A unique relationship exists between physicians and philosophers — one that expands on the constructive potential of the liaison between physicians and, for example, theologians, on the one hand, or, social workers on the other. This liaison should focus in the scientific aspects of medicine, not just the ethical aspects. Philosophers can provide physicians with a perspective on both the philosophy and the history of medicine through the ages — a sense of how medicine has adapted to the social cultural and ethical needs of each period. This perspective, while emphasizing medicine asscience, should not be limited to matters of methodology, or to criteria for distinguishing science from other intellectual pursuits, but should be concerned also with the history, sociology and politics of science. Both physicians and philosophers stand to gain from a strengthening of their active liaison now as never before; but most of all, the public will be the beneficiary. 相似文献

A paradigm for studying oral sensory tactile function through use of single frequency vibration applied to the dorsal surface of the tongue was administered to a group of 10 young black women and 10 young white normal-speaking women. Analyses showed no differences between groups with regard to lingual vibrotactile threshold of sensitivity or suprathreshold magnitude-estimation scaling responses. 相似文献

The purpose of this study was to investigate differences in function of the tactile sensory system between groups of normal-speaking children and children with articulation problems. This task was accomplished by studying possible tactile threshold shifts occurring during magnitude-estimation scaling of vibratory stimuli presented to the dorsal surface of the tongue. 10 normal-speaking children (M age = 7.8 yr.) and 9 children with articulation problems (M age = 7.5 yr.) participated. The normal-speaking children and articulatory defective children performed differently on the magnitude-estimation scaling task in which threshold was allowed to return to baseline after each stimulus presentation. These two groups of children also showed dissimilar threshold shifts for the suprathreshold intensities employed in the magnitude-estimation scaling. 相似文献

The possibility was explored that the informativeness of a specific region within a word can influence eye movements during reading. In Experiment 1, words containing identifying information either toward the beginning or toward the end were displayed asymmetrically around the point of fixation so that the reader was initially presented with either the informative or noninformative zone. Words were read with shorter summed initial fixation time when the reading was started from the informative zone. In Experiments 2 and 3, the target words were presented in sentences that were to be comprehended. More attention was given to the informative endings of words than to redundant endings. The latter were also skipped more often. The duration of the first fixation was not affected by information distribution within the word, whereas the second fixation duration was. The results of these experiments lend good support to the hypothesis of immediate lexical control over fixation behavior and to the notion of a convenient viewing position. 相似文献

In a study of the accuracy of recall of witnesses to a road accident, subjects watched a video recording of a natural scene for a few minutes. Two vehicles collided, and reports from the witnesses were taken using a version of the report form used by officers investigating road accidents in the UK. Witnesses were asked questions about the scene of the accident, about each of the two vehicles, and about the timing of the collision relative to a traffic signal. Does the accuracy of report depend upon the isolation of the witness? The study investigated this question by having some witnesses watch the video recording and complete the questionnaire alone, while other witnesses were encouraged to discuss their perceptions and recollections both while watching the recording and during an interval of a few minutes prior to administration of the questionnaire. All witnesses completed their reports in isolation. As a check on witnesses' expectancies, some of them, both individual and group witnesses, were informed prior to seeing the video recording that they would see a road accident and that they would be asked about it. The ‘uninformed’ witnesses were told to expect questions about the road scene. There was no overall difference between the recall accuracy of individual and group witnesses, but there was an interaction between groups and expectancy. When expecting to see a collision the group witnesses were more accurate than the individuals. Social facilitation in recall was restricted to occasions when the witnesses could anticipate the focus of the questions to be asked. 相似文献
