Larry Temkin challenged what seems to be an analytic truth about comparatives: if A is Φ-er than B and B is Φ-er than C, then, A is Φ-er than C. Ruth Chang denies a related claim: if A is Φ-er than B and C is not Φ-er than B, but is Φ to a certain degree, then A is Φ-er than C. In this paper I advance a context-sensitive semantics of gradability according to which the data uncovered by Temkin and Chang leave both statements intact. 相似文献

The role of central attention in visual short-term memory (VSTM) encoding and maintenance is well established, yet its role in retrieval has been largely unexplored. This study examined the involvement of central attention in retrieval from VSTM using a dual-task paradigm. Participants performed a color change-detection task. Set size varied between 1 and 3 items, and the memory sample was maintained for either a short or a long delay period. A secondary tone discrimination task was introduced at the end of the delay period, shortly before the appearance of a central probe, and occupied central attention while participants were searching within VSTM representations. Similarly to numerous previous studies, reaction time increased as a function of set size reflecting the occurrence of a capacity-limited memory search. When the color targets were maintained over a short delay, memory was searched for the most part without the involvement of central attention. However, with a longer delay period, the search relied entirely on the operation of central attention. Taken together, this study demonstrates that central attention is involved in retrieval from VSTM, but the extent of its involvement depends on the duration of the delay period. Future studies will determine whether the type of memory search (parallel or serial) carried out during retrieval depends on the nature of the attentional mechanism involved the task. 相似文献

In this study, we focused on marital adjustment among a sample of 101 Israeli women who had been married up to 3 years and
did not have children. We examined the contribution of variables from three ecological systems to marital adjustment: the
ontogenic system (attachment dimensions, and women’s perceptions of differentiation in the family of origin); the microsystem
(strategies for resolving marital conflicts); and the exosystem (characteristics of the husband’s employment). The findings
revealed that the higher the women’s levels in the two dimensions of attachment, the lower their levels of marital adjustment.
By contrast, the more the women used conflict resolution strategies of integration, concession, and compromise, the higher
their levels of marital adjustment. Conflict resolution strategies mediated the effects of attachment avoidance and family
differentiation on marital adjustment. To conclude, we offer practical recommendations for identifying couples at risk in
the first stage of marital life, and for professional interventions to improve marital adjustment at that stage. 相似文献

Morphological Processing in Adult Dyslexia 总被引:1,自引:0,他引:1
This study employed the masked-priming paradigm [Forster and Davis (J Exp Psychol bearn Mem Cogn 10: 680–698, 1984).], along with traditional methods of evaluation of morphological awareness and phonological processing, to obtain a finer-grained picture of the relationship between morphological abilities and reading in adult dyslexic readers. Participants were 21 dyslexic and 21 normally reading native Hebrew-speaking male college students. The results with masked priming demonstrated almost normal status of morphological knowledge in adult dyslexic readers with the presence of characteristic processing slowness. Phonological processing and morphological awareness were also shown to contribute primarily to word decoding in the regular and dyslexic group alike. At the same time, the contribution of different phonological skills to morphological priming effects (for pattern and root) dropped to zero. The findings demonstrated that weakness of dyslexic readers in morphological awareness tasks cannot be explained either by hypotheses on the structural deficit of morphological knowledge in dyslexia or by phonological deficit hypotheses. The explanation for this phenomenon seems to lie in the specific deficit of morphological processing, or even, more generally, in metalinguistic processing deficiency in dyslexia. 相似文献

The purpose of this research was to assess individual differences in students' retention of knowledge several years after studying the material. Assessment of retention of materials as a function of students' test anxiety can allow one to evaluate whether high test-anxious students' original deficient academic performance and organization of the materials are due to a retrieval deficit or a deficit in learning and knowledge organization. In two studies, students with different test-anxiety levels completed tasks that enabled us to evaluate both students' levels of knowledge and their cognitive organization of the materials. The tasks were administered either at the end of the course, or at different retention intervals up to 7 years after the end of learning. Results indicated that whereas high test-anxious students tested at the end of the courses performed worse than other students on tests of knowledge and cognitive organization, high test-anxious students tested at various retention intervals after the courses performed as well as other students. The theoretical and practical implications of these results are discussed. © 1997 John Wiley & Sons, Ltd. 相似文献

The controversy over the interpretative issue—is Thomas Reid a perceptual direct realist?—has recently had channelled into it a host of imaginative ideas about what direct perception truly means. Paradoxically enough, it is the apparent contradiction at the heart of his view of perception which keeps teasing us to review our concepts: time and again, Reid stresses that the very idea of any mental intermediaries implies scepticism, yet, nevertheless insists that sensations are signs of objects. But if sensory signs are not mental intermediaries, what are they? Hasn't Reid merely swapped the common ‘sensation’ for the notorious ‘idea’, ending up with indirect realism? 1 1This view is attributed to Reid by Hamilton (1865) and Mill (1877) , as well as Duggan 1960, Immerwahr 1978 , Chappell 1989 , Putnam 1994 , and Wolterstorff 2001 . Madden 1986 refuses to assign sensations any cognitive role. Others think that sensations are compatible with direct realism: See Cummins 1974, Daniels 1974, DeRose 1989, Pappas 1989, Haldane 1989, Copenhaver 2000 , and Van Cleve 2004 .
Current imaginative strategies answer negatively: Reid's sensory sign does not contradict direct perception, and those who think otherwise merely fail to understand what it means. 相似文献

Poststroke depression (PSD) is the most frequent psychological sequela following stroke. While previous studies describe the impact of age on brain infarct volume, brain edema, and blood–brain barrier (BBB) breakdown following ischemia, the role of age on PSD has yet to be described. Here, we examine the influence of age on PSD progression in a rat model of PSD by middle cerebral artery occlusion (MCAO). One hundred forty-three rats were divided into three groups. 48 rats 20 weeks of age underwent a sham procedure, 51 rats 20 weeks of age had MCAO, and 44 rats 22–26 months of age had MCAO. Groups were further divided into two subgroups. The first subgroup was used to measure infarct lesion volume, brain edema, and BBB breakdown at 24 h. In the second subgroup at 3 weeks after MCAO, rats were subjected to a sucrose preference test, two-way shuttle avoidance task, forced swimming test, and a brain-derived neurotrophic factor (BDNF) protein level measurement. Total and striatal infarct volume, brain edema, and BBB breakdown in the striatum were increased in older rats, as compared with younger rats. While both old and young rats exhibited depressive-like behaviors on each of the behavioral tests and lower BDNF levels post-MCAO, as compared with control rats, there were no differences between old and young rats. Although older rats suffered from larger infarct volumes, increased brain edema and more BBB disruption following MCAO, the lack of behavioral differences between young and old rats suggests that there was no effect of rat age on the incidence of PSD. 相似文献

A recalcitrant emotion is an emotion that we experience despite a judgment that seems to conflict with it. Having been bitten by a dog in her childhood, Jane cannot shake her fear of dogs, including Fido, the cute little puppy that she knows to be in no way dangerous. There is something puzzling about recalcitrant emotions, which appear to defy the putatively robust connection between emotions and judgments. If Jane really believes that Fido cannot harm her, what is she afraid of? This article seeks to show how recalcitrant emotion is possible. I argue that reductive theories that identify emotions with judgments, desires, or some combination thereof, cannot explain the possibility of emotional irrationality without contradiction. I then show that the appeal to sui generis attitudes also fails to solve the puzzle of recalcitrant emotions, and diagnose this failure as stemming from a misleading analogy between emotions and perceptions, and in particular, between recalcitrant emotions and perceptual illusions. The solution can be found in a different analogy: between emotions and actions; more specifically, between recalcitrant emotions and weakness of the will, akrasia. Like akratic actions, recalcitrant emotions entail responding to reasons, but to inferior reasons. Irrational but non-contradictory emotions are possible just as weakness of will is possible. 相似文献

This paper explores three cases of Do-It-Yourself, open-source technologies developed within the diverse array of topics and themes in the communities around the Public Laboratory for Open Technology and Science (Public Lab). These cases focus on aerial mapping, water quality monitoring and civic science practices. The techniques discussed have in common the use of accessible, community-built technologies for acquiring data. They are also concerned with embedding collaborative and open source principles into the objects, tools, social formations and data sharing practices that emerge from these inquiries. The focus is on developing processes of collaborative design and experimentation through material engagement with technology and issues of concern. Problem-solving, here, is a tactic, while the strategy is an ongoing engagement with the problem of participation in its technological, social and political dimensions especially considering the increasing centralization and specialization of scientific and technological expertise. The authors also discuss and reflect on the Public Lab’s approach to civic science in light of ideas and practices of citizen/civic veillance, or “sousveillance”, by emphasizing people before data, and by investigating the new ways of seeing and doing that this shift in perspective might provide. 相似文献
