Since Hume, philosophers of induction have debated the question of whether we have any reason for assuming that nature is uniform. This debate has always presumed that the uniformity hypothesis is itself coherent. In Part 1 of the following I argue that a proper appreciation of Nelson Goodman's so-called grue-green problem1 should lead us to the conclusion that the uniformity hypothesis, under its usual interpretation as a strictly ontological thesis, is incoherent. In Part 2 I argue that further consideration of the grue-green problem leads to the conclusion that certain popular versions of the thesis of physical supervenience/the primacy of physics, under their usual interpretation as strictly ontological theses, are false. In Part 3 I argue that the notions of natural kinds and nature's joints should not be taken as ontologically objective notions but as interest relative. Together Parts 1, 2, and 3 provide support for the Nietzsche-Goodman thesis that philosophers are prone to mistakenly identify as absolute, mind and language independent, features of the world which are in fact only features of a particular discourse, or of the world relative to a particular discourse. 相似文献

Recent findings have suggested that adults’ and children’s approximate number system (ANS) acuity may be malleable through training, but research on ANS acuity has largely been conducted with adults and children who are from middle- to high-income homes. We conducted 2 experiments to test the malleability of ANS acuity in preschool-aged children from low-income homes and to test how non-numerical stimulus features affected performance. In Experiment 1, mixed-effects models indicated that children significantly improved their ratio achieved across training. Children’s change in probability of responding correctly across sessions was qualified by an interaction with surface area features of the arrays such that children improved their probability of answering correctly across sessions on trials in which numerosity conflicted with the total surface area of object sets significantly more than on trials in which total surface area positively correlated with numerosity. In Experiment 2, we found that children who completed ANS acuity training performed better on an ANS acuity task compared with children in a control group, but they only did so on ANS acuity trials in which numerosity conflicted with the total surface area of object sets. These findings suggest that training affects ANS acuity in children from low-income homes by fostering an ability to focus on numerosity in the face of conflicting non-numerical stimulus features. 相似文献

An attractor network was trained to compute from word form to semantic representations that were based on subject-generated features. The model was driven largely by higher-order semantic structure. The network simulated two recent experiments that employed items included in its training set (McRae and Boisvert, 1998). In Simulation 1, short stimulus onset asynchrony priming was demonstrated for semantically similar items. Simulation 2 reproduced subtle effects obtained by varying degree of similarity. Two predictions from the model were then tested on human subjects. In Simulation 3 and Experiment 1, the items from Simulation 1 were reversed, and both the network and subjects showed minimally different priming effects in the two directions. In Experiment 2, consistent with attractor networks but contrary to a key aspect of hierarchical spreading activation accounts priming was determined by featural similarity rather than shared superordinate category. It is concluded that semantic-similarity priming is due to featural overlap that is a natural consequence of distributed representations of word meaning. 相似文献

It has been shown that when two arrays of Arabic numerals were briefly presented, observers could accurately indicate which array contained the larger number of a target numeral. This study investigated whether this rapid proportion comparison can be extended to other meaningful symbols that share some of notable properties of Arabic numerals. We tested mainly several Japanese Kanji letters, each of which represents a meaning and can work as a word. Using physically identical stimulus sets that could be interpreted as different types of letters, Experiment 1 first confirmed the rapid proportion comparison with Arabic numerals for Japanese participants. Experiment 2 showed that the rapid proportion comparison can be extended to Kanji numerals. Experiment 3 successfully demonstrated that rapid proportion judgments can be found with non-quantitative Kanji letters that are used frequently. Experiment 4 further demonstrated the rapid proportion comparison with frequently used meaningful non-letter symbols (gender icons). The rapid processing cannot be attributed to fluent processing of familiar items, because it was not found with familiar phonograms (Japanese Kana letters). These findings suggest that the rapid proportion comparison can be commonly found with frequently used meaningful symbols, even though their meaning is not relevant to the task. 相似文献

The role of the dynamic interactions between hydrogen in a solid solution and the stress-induced martensite transformation in hydrogen embrittlement has been investigated using trained Ni–Ti superelastic alloy. In a cyclic tensile test in the stress plateau region caused by stress-induced martensite and reverse transformations after hydrogen charging, a further decrease in the critical stress for the martensite transformation is observed. In addition, the number of cycles to fracture for a trained specimen is significantly larger than that for a non-trained specimen. Since most of the charged hydrogen is preferentially trapped in defects induced by training, the hydrogen embrittlement is considerably suppressed as a result of decreasing interactions between the hydrogen and the transformation. The present results indicate that hydrogen in a solid solution more strongly interacts with the stress-induced martensite transformation than hydrogen trapped in defects, thereby further enhancing the hydrogen embrittlement related to phase transformations. 相似文献

Long considered – perhaps naïvely – a relative oasis of Christian–Muslim calm, Kenya is seeing increased tension and conflict, mainly exacerbated by al-Shabaab militants, Kenyan military and Christian mobs. Concomitantly, the media and popular sentiment often vilify Somalis. This goes back to government agitprop during the ‘Shifta War’ of the 1960s. Among evangelical Christians, however, attitudes towards Somalis can prove more ambivalent. Drawing on interviews conducted with both Kenyan evangelical Christians and Somali Muslims, this article seeks to examine the theological shift among Kenyan evangelicals wherein they have re-cast Somalis as Samaritans and in doing so have made their primary approach to this conflict one of evangelization, not open hostility. This shift is due to a confluence of factors including community context, economic pragmatism and religious motivations, and the focus on evangelism does not necessarily preclude peace-building. What this article aims to present is a glimpse into the outlook of Kenyan evangelicals towards Somalis, particular Somali Muslims, and discuss these attitudes in the nexus of factors mentioned above. The article will reveal how, by re-casting the Somali ‘villain’ as Samaritan, some Kenyan evangelicals maintain boundaries and foster new identities in Eastern Africa for the sake of a longed-for peace. 相似文献

The present study addressed the issue of whether people who use perfume improve their “visual” interpersonal impression. This expectation comes from the possibility that those who wear perfume may modify their nonverbal behaviour through positive mood changes generated by the pleasant odour of perfume or through an increase of public self‐consciousness. Thirty‐one Japanese females were assigned to either a perfume or a no‐perfume group. A screening test held in advance confirmed that all the participants in the perfume group preferred the smell of the perfume used in this study. They participated in an interview and answered questions asked by a female confederate. In the middle of the interview, the interviewees in the perfume group put on the perfume. The improvement of their nonverbal behaviour in the latter half of the interview was evaluated by 18 neutral observers, who watched silent video clips of the interviews. The observers were not informed that some of the interviewees used perfume. The results of observer ratings showed that the interviewees in the perfume group showed significantly less nonsymbolic movement (touching their hair or nose, or shifting their posture such as rotating on a swivel chair) when wearing perfume. Analysis of the video clips showed that the interviewees in the perfume group decreased their nonsymbolic movement for about 6 s per minute after putting on the perfume. The female observers also rated the interviewees in the perfume group as more self‐confident. These findings suggest that wearing perfume inhibits behaviours that project negative impressions. Analysis of the subjective mood showed that the inhibition of an interviewee's nonsymbolic movement might have resulted from a wearer's positive mood change. Although several methodological issues limit the conclusions drawn from these results, the present study showed that wearing perfume has the potential to cause changes in nonverbal behaviour and to improve visual impressions. 相似文献
