Naturalistic research methods were used in this study to collect the voices, ideas, and opinions of rural, working poor, Appalachian families from Southeast Ohio about the stress of poverty in family life and family coping in the face of poverty. This data should be of interest to the professional family therapist who practices with the working poor. 相似文献

The central terms of certain theories which were valued highly in the past, such as the phlogiston theory, are now believed by realists not to refer. Laudan and others have claimed that, in the light of the existence of such theories, scientific realism is untenable. This paper argues in response that realism is consistent with — and indeed is able to explain — such theories' having been highly valued and yet not being close to the truth. It follows that the set of highly-valued past theories cited by Laudan, presumed to militate against realism, is in fact innocuous to the doctrine. The argument hinges largely on identifying the grounds on which theory-adoption is actually performed. 相似文献

This paper is concerned with the processing of informal arguments, that is, arguments involving probable truth. A model of informal argument processing is presented that is based upon Hample's (1977) expansion of Toulmin's (1958) model of argument structure. The model postulates that a claim activates an attitude, the two components forming a complex that in turn activates reasons. Furthermore, the model holds occurrence of the reason, or possibly the claim and the reason, activates values. Three experiments are described that provide support for the model.This research was supported by the Mellon Foundation and by the Office of Educational Research and Improvement of the Department of Education via an award for the Center for the Study of Learning to the Learning Research and Development Center.

Being unreasonable: Perelman and the problem of fallacies 总被引:1,自引:0,他引:1
James Crosswhite 《Argumentation》1993,7(4):385-402
Most work on fallacies continues to conceptualize fallacious reasoning as involving a breach of a formal or quasi-formal rule. Chaim Perelman's theory of argumentation provides a way to conceptualize fallacies in a completely different way. His approach depends on an understanding of standards of rationality as essentially connected with conceptions of universality. Such an approach allows one to get beyond some of the basic problems of fallacy theory, and turns informal logic toward substantive philosophical questions. I show this by reinterpreting three so-called fallacies - theargumentum ad baculum, equivocation and composition/division - in the light of Perelman's account. 相似文献

Wide-area computer networks provide a wealth of information services that have the potential to alter the approach toward scholarship taken by both students and researchers. Although it can be argued that the translation of information from hard copy to a publicly accessible electronic form has developed slowly, the total volume of text-based information that has been digitized is already staggering. Two major challenges facing psychologists wishing to develop their skills in network use are to identify and locate pertinent information that is accessible, and to find an easy way to retrieve it. This paper is an attempt to provide an overview of network resources and services that may be of particular interest to psychologists and psychology students. Its focus is on how to learn more about the available information services, as well as how to make access as user friendly as possible. 相似文献

Commercial database programs such as dBase and Paradox, although developed originally for business applications, are versatile and powerful tools that can be used for an academic purpose such as evaluating student performance. They can be used to write and store test questions, assemble and print classroom or on-line laboratory tests, and calculate grades, test statistics, and so forth. Databases are flexible, unlike textbook “ancillary” test bank programs that are inextricably bound to the strictly linear format and brief shelf life of specific textbook editions. A prototypical relational database program is described, with which an instructor can produce tests based on generic terms adapted from Boneau’s (1990) study of psychological literacy, as well as on behavioral learning objectives adapted from Bloom’s (1956) taxonomy of educational objectives. As a relational database, the program integrates terms, objectives, questions, tests, and test scores, and avoids unnecessary data duplication and waste of computer storage space. 相似文献

Abstract: I examine Derek Parfit's claim that it doesn't matter whether he survives in the future, if someone survives who is psychologically connected to him by “Relation R.” Thus, were his body to perish and be replaced by an exact duplicate, both physically and psychologically identical to him, this would be just as good as “ordinary” survival. Parfit takes the corollary view that replacement of loved ones by exact duplicates is no loss. In contrast, Peter Unger argues that we place nontransferable value in the lives of individual persons. I argue that the question of the preferability of Relation R over identity is unanswerable at present, as such hypothetical situations are too far removed from our experience to allow any reliable responses. I contrast cases involving artifacts, where we can make informed judgments concerning whether a given object's value would be transferred to a duplicate. 相似文献

A study is reported that tests the hypothesis that group members exhibit intergroup bias in response to the belief that outsiders will discriminate against them. To this end, two experimental conditions are included in which subjects anticipate either biased evaluations or fair evaluations respectively. In a control condition, subjects do not expect to be evaluated from an external source. Results indicated, as expected, that those who anticipated biased evaluations from an outgroup exhibited bias themselves, while those who anticipated fair evaluations exhibited outgroup favouritism. The fact that control subjects exhibited the same degree of bias as those who anticipated biased evaluations from the outgroup poses some difficulties for the hypothesized connection between anticipated discrimination and intergoup bias. Thus, it appears that intergroup bias is the rule and not the exception in an intergroup context. Nevertheless, it is clear that anticipated evaluations of outgroup members can effect intergroup bias. 相似文献
