Quantitative analyses of stimulus control and reinforcer control in conditional discriminations and delayed matching-to-sample procedures often encounter a problem; it is not clear how to analyze data when subjects have not made errors. The present article examines two common methods for overcoming this problem. Monte Carlo simulations of performance demonstrated that both methods introduced systematic deviations into the results, and that there were genuine risks of drawing misleading conclusions concerning behavioral models of signal detection and animal short-term memory.  相似文献

This work presents a view of Christian repentance as a process analogous to the development of Winnicott's capacity for concern and illuminated by Rowan Williams' theology of the Resurrection. One begins with fear of forfeiting one's attachment to the divine good mother, confronts the evidence of one's destructiveness in the Passion of Christ, experiences the risen Christ's object survival and acceptance of reparations, and attains a desire to contribute-in to God and neighbor.  相似文献

Algebras of Intervals and a Logic of Conditional Assertions   总被引:1,自引:0,他引:1  
Intervals in boolean algebras enter into the study of conditional assertions (or events) in two ways: directly, either from intuitive arguments or from Goodman, Nguyen and Walker's representation theorem, as suitable mathematical entities to bear conditional probabilities, or indirectly, via a representation theorem for the family of algebras associated with de Finetti's three-valued logic of conditional assertions/events. Further representation theorems forge a connection with rough sets. The representation theorems and an equivalent of the boolean prime ideal theorem yield an algebraic completeness theorem for the three-valued logic. This in turn leads to a Henkin-style completeness theorem. Adequacy with respect to a family of Kripke models for de Finetti's logic, ukasiewicz's three-valued logic and Priest's Logic of Paradox is demonstrated. The extension to first-order yields a short proof of adequacy for Körner's logic of inexact predicates.  相似文献

Let each of several (generally interdependent) random vectors, taken separately, be influenced by a particular set of external factors. Under what kind of the joint dependence of these vectors on the union of these factor sets can one say that each vector is selectively influenced by “its own” factor set? The answer proposed and elaborated in this paper is: One can say this if and only if one can find a factor-independent random vector given whose value the vectors in question are conditionally independent, with their conditional distributions selectively influenced by the corresponding factor sets. Equivalently, the random vectors should be representable as deterministic functions of “their” factor sets and of some mutually independent and factor-independent random variables, some of which may be shared by several of the functions.  相似文献

The study of equivalence relations exhibited by individuals with mental retardation and language limitations holds the promise of providing information of both theoretical and practical significance. We reviewed the equivalence literature with this population, defined in terms of subjects having moderate, severe, or profound mental retardation. The literature includes 55 such individuals, most of whom showed positive outcomes on equivalence tests. The results to date suggest that naming skills are not necessary for positive equivalence test outcomes. Thus far, however, relatively few subjects with minimal language have been studied. Moreover, we suggest that the scientific contributions of studies in this area would be enhanced with better documentation of language skills and other subject characteristics. With recent advances in laboratory procedures for establishing the baseline performances necessary for equivalence tests, this research area is poised for rapid growth.  相似文献

This study examined demographic characteristics, social competence, and behavior problems in clinic-referred children with gender identity problems in Toronto, Canada (N = 358), and Utrecht, The Netherlands (N = 130). The Toronto sample was, on average, about a year younger than the Utrecht sample at referral, had a higher percentage of boys, had a higher mean IQ, and was less likely to be living with both parents. On the Child Behavior Checklist (CBCL), both groups showed, on average, clinical range scores in both social competence and behavior problems. A CBCL-derived measure of poor peer relations showed that boys in both clinics had worse ratings than did the girls. A multiple regression analysis showed that poor peer relations were the strongest predictor of behavior problems in both samples. This study—the first cross-national, cross-clinic comparative analysis of children with gender identity disorder—found far more similarities than differences in both social competence and behavior problems. The most salient demographic difference was age at referral. Cross-national differences in factors that might influence referral patterns are discussed.  相似文献

声旁与整字的音段、声调关系对形声字命名的影响   总被引:12,自引:3,他引:9  
采用命名任务研究了汉字形声字的声旁与整字的音段、声调关系对形声字命名反应时的影响,探讨声旁的音段、声调在汉字形声字发音中的作用。实验材料是180个汉字形声字。实验结果表明,汉字形声字的声旁与整字的音段关系对命名时间有重要影响。汉字形声字的命名存在着“规则效应”,声旁与整字音段相同时反应快,声旁与整字音段相异时反应慢。汉字形声字的命名也存在着“声调效应”。声旁与整字的声调关系对命名有重要影响。当声旁与整字声调相同时反应快,当声旁与整字声调相异时反应慢,这种效应不受字频影响。整个实验结果支持汉字认知中强的亚词汇成分自动激活的观点。  相似文献

The literature on international relations frequently refers to culture in broad, macro-level ways to explain what cannot be explained by economic or military power. The assumptions that culture is simple, uniform and the opposite of power are, in the view of the authors, erroneous. Also, the authors note that there is a lack of scholarly interaction among psychologists interested in cross-cultural phenomena and international relations specialists interested in questions of identity and foreign policy. As an introduction to a special section on culture and foreign policy, this article calls for more communication among these scholarly communities; provides a set of observations about foreign policy and culture understood as a complex, dynamic concept; and calls for specific kinds of studies to better understand foreign policy in the context of cultural complexity and richness.  相似文献

Object relations family therapy (ORFT) is a psychoanalytically based approach for the treatment of couples and families which stresses the importance of past relationships. The therapist assumes a parentlike role and provides a holding environment in which clients can explore unconscious motivations. This paper will discuss the applicability of this method to genetic counseling. The case of a couple seen for recurrent trisomies will be presented and used as an example to discuss how ORFT might serve as a framework in a genetic counseling session.  相似文献

Starting with Sigmund Freud, psychoanalysts have written on a variety of topics relating to the diplomatic and political realms; but thus far their contributions primarily have been theoretical in nature, and have offered little of practical use to most diplomats and politicians. Various psychoanalytic theories have been applied, resulting in diverse conceptualizations: Wars are inevitable because of our inherent aggressive drives; a nation-state serves a maternal function for its members; certain large groups exhibit behaviors similar to those of adolescents. Yet these ideas do not significantly help us understand day-to-day events around the world, practical political issues, or international relations and diplomatic decisions.  相似文献
