The paper puts forward the thesis of conceptual pragmatism: that there are pragmatic choices to be made between distinct but similar concepts within various contexts. It is argued that this thesis should be acceptable to all who believe in concepts, whether the believers are platonists, realists or anti-realists. It is argued that the truth of the thesis may help to resolve many long-standing debates, and that in any case it will lead to an extension of philosophical method. The paper then briefly considers the concepts of belief and desire as a case-study, and argues for the recognition of the practical reasoner's stance (to stand alongside Dennett's intentional stance), relative to which we should select concepts of belief and desire which are broadly cartesian.I am grateful to the following for their help (varying from detailed comments and criticisms on earlier drafts, to general advice and encouragement): David Archard, Simon Blackburn, Jack Copeland, Dan Dennett, Susan Levi, Christopher McKnight, Derek Parfit, Michael Slote, Tim Williamson, and Crispin Wright. 相似文献

This is a report of the completion responses for 40 three-letter word stems (e.g., ABO) produced by 100 undergraduate students at the University of California at San Diego. The report includes a list of the different words that were written as stem completions, their frequency of occurrence as completions, and their frequency of occurrence in English according to published norms. This list of materials is useful for the construction of completion tests for future investigations of direct priming phenomena, and it may provide an important covariate in the analysis of performance on completion tests. Preliminary analyses of the results reveal three primary factors that determine overall performance on a stem-completion test: word frequency, word length, and meanings per word. Analyses of the completions produced for each individual word stem, however, reveal that usually only one of these factors makes a significant contribution to performance. 相似文献

In two experiments, we investigated the factors that influence the perceived similarity of speech sounds at two developmental levels. Kindergartners and second graders were asked to classify nonsense words, which were related by syllable and phoneme correspondences. The results support the existence of a developmental trend toward increased attention to individual phonemic segments. Moreover, one significant factor in determining the perceived similarity of speech sounds appears to be the position of the component correspondences; attention to the beginning of utterances may have developmental priority. An unexpected finding was that the linguistic status of the unit involved in a correspondence (whether it was a syllable or a phoneme) did not seem particularly important. Apparently, the factors which contribute to the perceived similarity of speech sounds in the classification task are not identical to those which underlie performance in explicit segmentation and manipulation tasks, since in the latter sort of task, syllables are more accessible than phonemes for young children. The present task may tap a level of processing that is closer to the one entailed in word recognition and lexical access. 相似文献

The term 'multi-agency' family is preferred to 'disorganized' family. Multi-agency family systems present special problems of the relationships (a) within the family, (b) between family and professional network, (c) among members of the professional network and (d) between family, network and treatment centre to whom the family is referred. Pressures on the family and professional workers can create a locked system which prevents natural development of the family or effective problem solving by the workers. A systems approach to such problems is presented which includes consultation to the family/professional network system. 相似文献

Axiomatizations of ordered preference differences typically assume that preferences are ordered. However, the mere assumption that preference differences can be ordered says nothing about whether preferences themselves are ordered. Utility representations for ordered differences without ordered preferences are investigated. 相似文献

This paper reviews the literature on scapegoating, elaborating on the underlying mechanisms before describing the process of scapegoating as it occurred in a neonatal nurse support group. Illustrative vignettes are used to discuss how scapegoating was used by group members to avoid painful feelings arising from their care of extremely ill infants. Group process is related to the stages of the group's development as feelings were addressed more directly and the need to use scapegoating as a defense decreased. 相似文献

Summary Subjects were shown eight-letter pseudowords tachistoscopically and were asked to report as many letters as possible. The pseudowords, examples of either first- or fourth-order approximation to English, were printed in normal or reversed spelling and were presented in either normal of mirror-imaged letters. Finally subjects were either free to report in any order they wished, or they were instructed to report from left to right or from right to left. With normal letters, the familiarity effect was controlled by the spelling direction, not by the direction of report or the match between direction of report and spelling direction. With mirrored letters, however, order of approximation to English had no effect. The results contradict two existing theories: Mewhort's theory claims that the familiarity of fourth-order materials aids processing at a postcategorical level; it has trouble explaining why the familiarity effect disappeared with mirrored letters and normal spelling. Wolff's theory claims that familiarity aids processing at the feature level; it has trouble explaining why the familiarity effect disappeared with mirrored letters and reversed spelling. 相似文献

This paper reports some preliminary data on a “window-pointer” technique for measuring word processing time in reading. In this technique, almost all of the letters are masked on a page of text shown on a video monitor. The letters can be seen only through a “window” showing one word on one line. Subjects control the horizontal location of the window by moving a pointer left and right. When subjects want to move the window to the next line, the window is moved off the right end of the current line, and the pointer is moved back to the left. The window then reappears at the beginning of the next line. After some practice, subjects can move the window in approximate synchrony with their eyes, and can read the passage without any difficulty. The length of time the window spends on each word can then be used as a measure of word processing time. An analysis of these window durations indicates that they are similar in many respects to the gaze durations obtained with eye-movement monitoring techniques. 相似文献
