In this paper, I develop a criticism to a method for metaontology, namely, the idea that a discourse’s or theory’s ontological commitments can be read off its sentences’ truth-conditions. Firstly, I will put forward this idea’s basis and, secondly, I will present the way Quine subscribed to it (not actually for hermeneutical or historic interest, but as a way of exposing the idea). However, I distinguish between two readings of Quine’s famous ontological criterion, and I center the focus on (assuming without further discussion the other one to be mistaken) the one currently dubbed “ontological minimalism”, a kind of modern Ockhamism applied to the mentioned metaontological view. I show that this view has a certain application via Quinean thesis of reference inscrutability but that it is not possible to press that application any further and, in particular, not for the ambitious metaontological task some authors try to employ. The conclusion may sound promising: having shown the impossibility of a semantic ontological criterion, intentionalist or subjectivist ones should be explored.  相似文献

The aim of the study is to evaluate the usefulness of the Bem Sex Role Inventory (BSRI; Bem, 1974), an overall measurement of the cultural construct of masculinity and femininity, in the psychological assessment of Spanish transsexuals. Seventy male-to-female transsexuals (MF), 51 female-to-male transsexuals (FM), 77 control men, and 79 control women completed the Spanish version of the BSRI. Statistically significant differences between groups were only found on the femininity scale, on which MF transsexuals and control women scored significantly higher than FM transsexuals and control men. The results indicate that (a) only the femininity scale of the BSRI appears to be useful today for evaluating differences in the sex-role identification in Spanish controls and transsexuals; and (b) MF and FM transsexuals score as a function of their gender identity instead of their anatomical sex on the BSRI femininity scale.  相似文献

Loneliness is a subjective and emotionally unpleasant experience of perceiving insufficient social relationships. Previous research has revealed that loneliness constitutes a psychosocial risk factor for depression, and is also related to unhealthy behaviors such as smoking. This study aims to examine the relation between loneliness, depression, and cigarette dependence, and to explore the role of sex in this relationship. A total sample of 275 adult treatment-seeking daily smokers (Mage = 45.3; 61.5% females) was used. Our results showed a significant correlation between higher scores of loneliness, depressive symptoms, and cigarette dependence. In addition, mediation analysis showed a significant indirect effect of loneliness on cigarette dependence, via depressive symptoms. Regarding the effect of sex, we found that this variable significantly moderated the relationship between depressive symptoms and cigarette dependence. Results of this study extend previous literature by showing that, in treatment seeking smokers, loneliness is a significant predictor of depressive symptoms, and through this relation, it predicts cigarette dependence. Additionally, sex was a significant moderator of this relation. These findings have several clinical implications, and also contribute to the understanding of cigarette dependence, which is a well-known barrier for smoking cessation.  相似文献

The purpose of this study was to analyze the effect of the media on individuals’ specific language use in relation to a news story on immigration: the influence of the news frame and group cue. Abstraction, complexity of language use, and negative affective language were evaluated. The 523 participants were randomly distributed to each of the four experimental conditions: news frame (crime versus economic contribution) by group cue (geographical origin of the immigrants involved: Moroccans versus Latin Americans). Through content analysis of the ideas and reflections that arose after the participants read the different news stories, using the Linguistic Category Model (LCM; Semin & Fiedler, 1991) to measure abstract language and the Linguistic Inquiry and Word Count (LIWC; Pennebaker, Booth, & Francis, 2007) to analyze complex language and negative affective language, it emerged that abstract language and negative affective language were more frequent in the participants assigned to the news frame on crime. Complex language was more commonly used when the news frame referred to the economic contribution of immigrants. Regression analyses showed the mediating role of attitude to immigration in the effects of news frame on negative affective language. The bootstrap method was used to assess the magnitude of the indirect effect. A significant mediator effect was also found through structural equation modeling. Analyses of covariance showed one interaction between news frame and group cue: Among those who read the news story in a frame linking immigration to crime and Moroccan origin, abstract language was more characteristic. The results are discussed from the theoretical perspective of framing.  相似文献

The goal of the present study is to develop a questionnaire, with proper psychometric properties and current norms, to evaluate the burnout syndrome in Spain. The operative definition of burnout proposed by Maslach and Jackson is used to define three dimensions (Emotional exhaustion, Depersonalization and Personal accomplishment). A total of 2,403 national Spanish police participated. Evidence of construct validity was checked through cross validation (showing a good fit of the three factors model to the data). Using the MBI, NEO-FII and CECAD evidence of convergent validity and criteria validity were developed (showing that the relations are similar to the ones that appear in other research). The discrimination, mean, standard deviation, and typical error of the average of the items composing the various dimensions were analyzed. Both the Cronbach's alpha coefficient and the conditional standard error of measurement (CSEM) were calculated for each of the dimensions. The results showed good internal consistency (all α values > .85). Finally, the questionnaire was scaled using T scores. The psychometrical properties reported here support the use of this new questionnaire for the burnout evaluation in Spanish police.  相似文献

Recent evidence from masked priming experiments has revealed that readers regularize letter-like symbols and letter-like numbers into their corresponding base letters with minimal processing cost. However, one open question is whether the same pattern occurs when these items are presented during normal silent reading. In the present study, we respond to this question in an eye-movement experiment that included sentences with words that had symbols and numbers as letters, as in “YESTERDAY I SAW THE SECRE74RY WORKING VERY HARD”. Results revealed that there is a greater reading cost associated with letter-by-number replacements than with letter-by-symbol replacements, especially when the replaced letters occur at the beginning of the word. We examine the implications of these findings for models of visual word recognition and reading.  相似文献

The paper makes a twofold contribution. Firstly, it advances a preliminary account of the conditions that need to obtain for constitutional rights to be democratic. Secondly, in so doing, it defends precommitment-based theories from a criticism raised by Jeremy Waldron—namely, that constitutional rights do not become any more democratic when they are democratically adopted, for the people could adopt undemocratic policies without such policies becoming democratic as a result. The paper shows that the reductio applies to political rights, yet not to non-political rights, such as reproductive, environmental, or privacy rights. The democratic status of the former is process-independent. The latter, by contrast, are democratic precisely when they are adopted by democratic means.  相似文献

Based on a transactional model of stress, this study aims to understand the role played by attributions in selecting surface acting as emotion regulation strategy when coping with emotion‐rule dissonance. A sample of primary health care professionals (n = 87) based in Madrid filled in a questionnaire. Hierarchical multiple regression analyses were conducted to test hypotheses on the moderating effects of attributions on the relationship between emotion‐rule dissonance and surface acting. Results showed that high levels of attribution to patients of responsibility for negative events, low levels of professionals' self‐accountability, and low attribution of being able to promote a positive change strengthen the positive association between emotion‐rule dissonance and surface acting. This could explain why professionals use a potentially damaging emotion regulation strategy.  相似文献

This article introduces the ArduiPod Box, an open-source device built using two main components (i.e., an iPod Touch and an Arduino microcontroller), developed as a low-cost alternative to the standard operant conditioning chamber, or “Skinner box.” Because of its affordability, the ArduiPod Box provides an opportunity for educational institutions with small budgets seeking to set up animal laboratories for research and instructional purposes. A pilot experiment is also presented, which shows that the ArduiPod Box, in spite of its extraordinary simplicity, can be effectively used to study animal learning and behavior.  相似文献

This paper explores consumers' commitment to and conviction about their beliefs in the form of attitude certainty. Based on a review of past research, we present a new framework for understanding attitude certainty and how consumers' attitude certainty is shaped by their resisting or yielding to persuasive messages, or even by their reflections on the evidence supporting their attitudes. We propose that attitude certainty is formed and changed largely through an attribution-based reasoning process linked to a finite set of distinct appraisals. Our framework is used to both organize past research and offer guidance for future research endeavors. In addition, we distinguish our framework of appraisal-based attitude certainty from past models in attitudes and persuasion research that have referenced or taken note of the attitude certainty construct. Implications and future directions for the study of consumer behavior are discussed.  相似文献
