This paper discusses the possibility of an ethics of difference. It begins with an introduction to current poststructural and critical theories in order to show their significance for transcultural politics and ethics. Its theme is formulated in terms of the debate between the affirmation of ethical cognitivism cast in the form of universalism and the advocacy of moral skepticism in the mode of communitarianism. Distancing itself from the idea of universal morality, this paper attempts to respond to the challenge of both communitarians and deconstructionists in contemporary French poststructuralism. In the end, it argues for transversality in place of universality.  相似文献

The present study addressed limitations of a recent confirmatory factor analytic study challenging the hypothesized factor structure of the Beavers Interactional Scales. That dataset (n = 97) was reanalyzed and two additional datasets (n = 95, n = 91) were explored. With all three samples, taken separately and together, the Beavers Systems Model, when operationalized in the BIS, was not supported. A body of evidence is accumulating which suggests that clinicians and researchers should be wary of the BIS.  相似文献

The relationship between inspection time (IT) and paper-and-pencil tests of cognitive ability is well documented. However, the extent to which IT relates to cognitive ability through general intelligence or through group factors such as performance has not been fully addressed. Another unresolved issue is whether IT relates to psychometric intelligence independent from other elementary cognitive tasks. The current study examined these issues in a sample of 6–13-year-old twins drawn from the Western Reserve Twin Project (WRTP) (n=568 participants). Analyses suggest that IT and other elementary tasks predict general intelligence. IT also predicts Performance ability while other elementary tasks do not. Furthermore, IT contributes variance to cognitive ability independent from other elementary tasks. These suggest that multiple indices of elementary cognitive ability are necessary to fully understand their relationship with complex psychometric measures.  相似文献

In a study designed to investigate the respective roles of religious fundamentalism and right‐wing authoritarianism as predictors of prejudice against racial minorities and homosexuals, participants (47 males, 91 females) responded to a series of questionnaire measures of these constructs. Data were analyzed using multiple regression. Consistent with previous research, authoritarianism was a significant and strong positive predictor of both forms of prejudice. With authoritarianism statistically controlled, however, fundamentalism emerged as a significant negative predictor of racial prejudice but a positive predictor of homosexual prejudice. In a second study, we conducted parallel multiple regressions using the correlations from two previously published studies. The Study 1 results were replicated exactly, except that fundamentalism was a nonsignificant predictor of homosexual prejudice. We interpret the results as evidence that Christian fundamentalism consists of a second major component other than authoritarianism—related to Christian belief content—that is inversely related to some forms of prejudice (including racial prejudice) but not others (e.g., homosexual prejudice).  相似文献

This questionnaire study was designed to confirm and further explore an earlier finding of a gender difference in post-termination patient-analyst contact, as well as to assess whether practices regarding post-termination contact have changed in the five-year interval since the first study. The hypothesis that women analysts are more likely to have post-termination contact with their analysands than men analysts was confirmed by the present study. Analysts who report thinking frequently about their most significant analyst are contacted by a much larger proportion of prior patients than those who rarely think about their analyst. Further, women analysts are more likely to feel they benefited from the analysis they consider their most significant analysis, and to feel positively about that analyst. In 1994, analysts were much more accepting of and more likely to propose post-termination contact than in 1989. What the analyst reports he/she says to the patient is associated with the likelihood of such contact.  相似文献

This paper presents a model of the cognitive processes that precede decisions to help another person. The empathy‐prospect model predicts that potential helpers make decisions in much the same way as decision makers in other contexts do (i.e., they evaluate prospects) and that perceptions of need and the empathic reactions and intentions to help that they generate will be stronger for people observing losses rather than gains. The model also predicts that intentions to help should increase when (a) the predicament is serious, (b) money is not involved, or (c) help entails few costs for the potential altruist. The results from 2 experiments provide clear support for these predictions. The findings suggest that (a) the gains or losses of another person contribute to perceptions of that person's needs and feelings of empathy, (b) empathy is the primary proximal determinant of prosocial motivations, and (c) potential losses that are serious accentuate altruistic reactions.  相似文献

In this paper I argue that the ontological interpretation of the concepts of reduction and emergence is often misleading in the philosophy of science and should nearly always be eschewed in favor of an epistemological interpretation. As a paradigm case, an example is drawn from the philosophy of chemistry to illustrate the drawbacks of “ontological reduction” and “ontological emergence,” and the virtues of an epistemological interpretation of these concepts.  相似文献

Pigeons were trained on a concurrent-chains procedure in which the initial link associated with the shorter terminal-link delay to food changed unpredictably across sessions. In the minimal-variation condition, delays were always 10 s and 20 s, whereas in the maximal-variation condition delays were generated pseudorandomly for each session. On some terminal links, food was withheld to obtain measures of temporal control. Measures of choice (log initial-link response ratios) and timing (start and stop times on no-food trials) showed temporal control and stabilized within the 1st half of each session. In the maximal-variation condition, choice was a nonlinear function of the log delay ratio, consistent with a categorical discrimination but contrary to models based on the matching law. Residuals from separate regressions of log response and log start and stop time ratios on log delay ratios were positively correlated. Overall, results support cognitive models that assume that initial-link choice is based on an all-or-none decision process, and that choice and timing are mediated by a common representation of delay.  相似文献

The role of drug expectancy in the control of human drug seeking   总被引:2,自引:0,他引:2  
Human drug seeking may be goal directed in the sense that it is mediated by a mental representation of the drug or habitual in the sense that it is elicited by drug-paired cues directly. To test these 2 accounts, the authors assessed whether a drug-paired stimulus (S+) would transfer control to an independently trained drug-seeking response. Smokers were trained on an instrumental discrimination that established a tobacco S+ in Experiment 1 and a tobacco and a money S+ in Experiment 2 that elicited an expectancy of their respective outcomes. Participants then learned 2 new instrumental responses, 1 for each outcome, in the absence of these stimuli. Finally, in the transfer test, each S+ was found to augment performance of the new instrumental response that was trained with the same outcome. This outcome-specific transfer effect indicates that drug-paired stimuli controlled human drug seeking via a representation or expectation of the drug rather than through a direct stimulus-response association.  相似文献

We address points raised by Zajonc and Sulloway, who reject findings showing that birth order has no effect on intelligence. Many objections to findings of null birth-order results seem to stem from a misunderstanding of the difference between study designs where birth order is confounded with true causal influences on intelligence across families and designs that control for some of these influences. We discuss some of the consequences of not appreciating the nature of this difference. When between-family confounds are controlled using appropriate study designs and techniques such as multilevel modeling, birth order is shown not to influence intelligence. We conclude with an empirical investigation of the replicability and generalizability of this approach.  相似文献
