This paper argues that the hypothesis proposed in the Meno is the proposition ‘virtue is good’ alone, and that its epistemic nature is essentially insecure. It has been an object of huge scholarly debate which other hypothesis Socrates posited with regard to the relationship between virtue and knowledge. This debate is, however, misleading in the sense of making us believe that the hypothesis that virtue is good is regarded as a truism in the light of the process of positing a higher hypothesis described in the Phaedo and the Republic. I argue that the hypothesis in question is presented as a result of the earlier discussion of Meno's third definition of virtue (77b2–79a2), which implies the consequence that morally correct actions are beneficial whether or not accompanied by conventional goods such as wealth and honour. The underlying role of presenting it as a hypothesis is therefore to postpone demonstrating the truth of a controversial thesis which needs a substantial justification. In conclusion, I suggest that Plato's real intention in introducing the method of hypothesis in the dialogue is not to answer the original question but to lead Meno to seek for knowledge. 相似文献

This study examined the relationships between contact frequency, experiences of intergroup contact and a number of demographic intergroup variables. A telephone survey was conducted among 544 blacks (57.5% male; 42.5% female) and 478 whites (44.6% male; 55.4% female). Three CHAID models with attitudes towards blacks and Afrikaans-speaking and English-speaking whites as dependant variables were investigated. Contact experience rather than frequency was the most significant predictor of racial attitudes. Age and geographical location were significant predictors of black attitudes towards the two white groups. A complex web of factors seems to influence intergroup relations in culturally heterogeneous societies. 相似文献

Business and public organisations hire fraud examiners to conduct private investigations when there is suspicion of misconduct or financial crime. Fraud examiners carry out their investigation based on a mandate. Often, individuals in the organisation are suspects. The blame game hypothesis is concerned with factors that cause blame attribution to some individuals but not to others. In this case study, only executives were blamed who had not disclosed corruption information to a major shareholder and to the chief executive officer. 相似文献

口语词汇产生过程中存在语义抑制和语义促进效应, 可能发生在概念准备和词汇选择或者后词汇水平阶段。本研究采用图画-词汇干扰实验任务, 变化图画与词汇出现点之间的时间间隔(stimulus onset asynchrony, SOA), 运用脑电技术考察口语词汇产生中语义效应发生的时间进程。结果显示, 当SOA为0 ms时表现出语义抑制效应, 语义效应发生在词汇选择阶段(344~418 ms); 当SOA为-400 ms时, 语义效应发生在概念准备阶段(0~76 ms)和词汇选择阶段(274~390 ms); 460~594 ms时间窗口内的语义效应可能表明讲话者对语义信息的自我监测。词汇产生中存在语义促进效应和抑制效应的权衡, 影响了行为结果中语义效应的方向, 上述发现支持了口语词汇产生的词汇竞争假说。 相似文献

A fundamental motor learning principle conveyed in textbooks is that augmented terminal feedback frequency differentially affects motor learning and performance. The guidance hypothesis predicts that relative to a reduced frequency of feedback, providing learners with feedback following every practice trial enhances practice performance but degrades subsequent motor learning. This change in effectiveness for each relative feedback frequency is called a reversal effect, and because it is thought that practice variables can have distinct impacts on learning and performance, delayed retention tests are considered the gold standard in motor learning research. The objectives of this meta-analysis were to a) synthesize the available evidence regarding feedback frequency, performance, and motor learning to test whether there are significant changes in effectiveness from acquisition and immediate retention to delayed retention, b) evaluate potential moderators of these effects, and c) investigate the potential influence of publication bias on this literature. We screened 1662 articles found in PubMed and PsycINFO databases as well as with reference tracing and a targeted author search. A final sample of 61 eligible papers were included in the primary analysis (k = 75, N = 2228). Results revealed substantial heterogeneity but no significant moderators, high levels of uncertainty, and no significant effect of reduced feedback frequency at any time point. Further, multilevel analyses revealed no evidence of a significant change in effect from acquisition or immediate retention to delayed retention. Z-curve analysis suggested the included studies were severely underpowered. These results suggest that robust evidence regarding feedback frequency and motor learning is lacking. 相似文献

重复知盲是在快速系列视觉呈现任务中对第二个重复刺激的加工缺陷。以汉语中反义字和成语为实验材料,采用全部报告任务,探讨刺激的语义关联性对重复知盲的影响。实验1以汉语单字为材料,采用单因素三水平(目标刺激之间的语义关系:无关、相同、相反)被试内设计,结果是重复字产生重复知盲效应,反义字产生语义启动效应。实验2以成语为材料,采用2(目标刺激之间的语义关系:相同、无关)×2(位置:前位置、后位置)设计,结果是语义关联性消解了重复知盲效应。结果表明:(1)反义字不产生重复知盲效应。(2)语义关联性消解成语中重复字的重复知盲效应。(3)实验结果支持竞争假设。 相似文献

Writing from experiences in the consulting room in private practice in Australia, the author refers to the layered complexity of a conflict of ethical duty which has legal and social implications. The paper explores how the ethics that are congruent with creating a safe vas bene claustrum can be diametrically opposed to the social and legal structures and processes on which we all rely. It is suggested that within the vas, analysts and analysands engage in a shared process of emotionally connected, layered, symbolic thinking. Subpoenas directed at analysts are seeking concrete evidence that will stand up in court. The paper argues that this is a category error based on ignorance and misconceptions of what analytic work entails. The intrusion of a subpoena into the vas has the potential to cause havoc in the mental health and the lives of already vulnerable, possibly traumatized and isolated individuals. It can undermine a fundamental human right and undermine the profession of psychotherapy as a whole. The paper proposes that analysts have an ethical obligation to protect the work contained within the vas from these category errors and to educate other professionals as to why we cannot provide the kind of evidence that the courts require. 相似文献

According to recent studies, people on both the political right and left show prejudice toward groups whose beliefs are in conflict with their own. This prediction applies to both cultural and economic dimensions of political beliefs. In three studies (N = 499) we demonstrate that people on both the cultural and economic right and left show negative attitudes toward groups on the other side of the given spectrum and that underlying this effect is the perception of value violation. In two out of three studies, we manipulated the extremity of target worldviews to further explore the causal chain between political beliefs, the perception of value violation, and prejudice. Our results showed a high degree of symmetry between the political left and right in their attitudes toward groups with dissimilar beliefs. However, although people on both sides of the political spectrum show prejudice toward each other, people on the cultural and economic right seem to be more sensitive to value violations than people on the left. 相似文献
