The miracle argument for scientific realism can be cast in two forms: according to the miraculous theory argument, realism is the only position which does not make the empirical successes of particular theories miraculous. According to the miraculous choice argument, realism is the only position which does not render the fact that empirically successful theories have been chosen a miracle. A vast literature discusses the miraculous theory argument, but the miraculous choice argument has been unjustifiably neglected. I raise two objections to Richard Boyd's defense of the latter: (1) we have no miracle free account of the emergence of take-off theories and (2) the anti-realist can account for the non-miraculous choice of empirically successful theories by attributing mere empirical adequacy to background theory. I argue that the availability of extra-empirical criteria that are arguably truth conductive but not theory-laden suffices to answer (1), and the unavailability of extra-empirical criteria that are conductive to empirical adequacy but not necessarily to truth (and are also not theory-laden) constitutes to reply to (2). The prospects for a realist victory are at least somewhat promising, on a controversial assumption about the rate at which empirically successful theories emerge. 相似文献

In this paper, logics are conceived as two-sorted first-order structures, and we argue that this broad definition encompasses a wide class of logics with theoretical interest as well as interest from the point of view of applications. The language, concepts and methods of model theory can thus be used to describe the relationship between logics through morphisms of structures called transfers. This leads to a formal framework for studying several properties of abstract logics and their attributes such as consequence operator, syntactical structure, and internal transformations. In particular, we treat Belief Revision Systems (BRS) as our main example, defining the Wide Belief Revision Systems (WBRS's). This generalization allows us to define BRS's in an abstract setting for classical and non-standard logics. We also show how the concept of translation between logics can be obtained as a particular case of transfers. 相似文献

The psychometrics of many self-report measures of anxiety and depression have been established for patients with anxiety disorders, but little is known about use of these measures in patients with psychotic disorders. This study examined psychometrics of commonly used self-report measures. Self-report measures and interviewer ratings were collected on 33 outpatients diagnosed with schizophrenia disorders. A sample of 46 patients with anxiety disorders completed the same self-report measures. Internal consistency was high for the self-report measures in both samples. Test-retest reliability was moderate to high. Scores on self-report measures were correlated with interviewer ratings and with scores on other self-report measures of similar constructs, supporting the convergent validity of the measures. Reliable and valid information about anxiety and depression can be obtained through administering the self-report measures to outpatients diagnosed with psychotic disorders. There was more overlap among measures than was expected, possibly because of poor discriminant validity. One explanation of this may be that anxiety constructs overlap more in patients with schizophrenia or related disorders than in non-psychotic populations. 相似文献

The authors examined the roles of self-esteem and perceived social support in moderating the relationship between dual social expectations (instrumentality and expressivity) and well-being. Participants were 166 female and 87 male students in an urban community in the midwestern United States. After the authors controlled for the main effects of instrumental and expressive expectations, social support, as predicted, moderated the relationship between dual expectations and well-being: With higher levels of social support, higher levels of dual expectations were associated with higher levels of well-being; with lower levels of social support, higher levels of dual expectations were associated with lower levels of well-being. Contrary to predictions, however, self-esteem did not moderate the relation between dual expectations and well-being. The discussion focuses on the importance of social resources in enhancing the potential benefits of dual expectations in interpersonal contexts. 相似文献

One hundred ninety-five boys with attention-deficit/hyperactivity disorder (ADHD) were compared with 73 comparison boys (M = 9.83 years, SD = 1.30) on self-perceptions relative to a teacher-rated criterion. Emphasis was placed on ADHD subgroup comparisons according to level of aggression, academic achievement, and depression compared with control boys. Consistent with the authors' prediction, ADHD boys overestimated relative to teacher report, more than did controls, in the scholastic competence, social acceptance, and behavioral conduct domains. Examination of discrepancy scores (child rating - teacher rating) by comorbidity subgroups suggested that aggressive and low-achieving ADHD boys tended to overestimate their competence the most in the domains in which they were the most impaired. Results are discussed in terms of prior literature on "positive illusions" in ADHD children. 相似文献

Breast cancer remains a highly prevalent and extraordinarily stressful experience for hundreds of thousands of women each year in the United States and around the world. Psychological research has provided a picture of the emotional and social impact of breast cancer on patients' lives, and of factors associated with better versus worse adjustment. Psychosocial interventions have been beneficial in decreasing patients' distress and enhancing their quality of life. Recent research also suggests that psychological factors may be related to potentially important biological disease-related processes. In addition to providing an understanding of the psychological factors in breast cancer, research in this area has provided a framework for research on adaptation to health-related stress in general. 相似文献

Extracellular signal-regulated kinase activity in the entorhinal cortex is necessary for long-term spatial memory 总被引:2,自引:0,他引:2

Lesion studies have provided evidence that the entorhinal cortex (EC) participates in spatial memory. However, the molecular cascades that underlie memory-associated changes in the EC and its specific role in spatial memory, however, have not been clearly delineated. Recently, it has been shown that activation of extracellular signal-regulated kinase (Erk, a mitogen-activated protein kinase family member) in the dorsal hippocampus is necessary for spatial memory. To examine whether similar mechanisms are used for spatial memory storage in the EC, Erk activity was inhibited after training in the Morris water maze. Bilateral infusion of the mitogen-activated protein kinase kinase inhibitor PD098059 into the EC immediately after training resulted in a memory deficit observed during a retention test performed 48 h later. This deficit was abolished with pretraining in a different water maze in which animals were able to learn the general task requirements and the appropriate search strategies. The absence of a deficit indicates that Erk activity in the EC may be involved in storing the task requirements or the search strategies. The findings presented in this article are consistent with the idea that the EC is involved in spatial memory and indicate that Erk activity is necessary for memory consolidation in this structure. 相似文献

Psychotherapy researchers are increasingly engaged in collaborations with clinical practitioners and mental health administrators. Each party brings its own perspectives, values, and agendas to bear in these encounters. Viable research—practice collaborations depend on understanding and negotiating some of the tensions in these relationships. In this article, we discuss the contexts that prevail for various participants in a psychotherapy dissemination study as well as the values, goals, costs, and benefits related to research participation. This article is a collaboration among the researchers, mental health administrators, therapists, and clients involved in an ongoing treatment dissemination study. Our recommendations for research—practice collaborations are based on our experiences and dialogues over the course of this study. 相似文献
