Jonathan Westphal’s recent paper attempts to reconcile the view that propositions about the future can be true or false now
with the idea that the future cannot now be real. I attempt to show that Westphal’s proposal is either unoriginal or unsatisfying.
It is unoriginal if it is just the well-known eternalist solution. It is unsatisfying if it is instead making use of a peculiar,
tensed truthmaking principle.

Number sense and quantifier interpretation 总被引:1,自引:1,他引:0
We consider connections between number sense—the ability to judge number—and the interpretation of natural language quantifiers.
In particular, we present empirical evidence concerning the neuroanatomical underpinnings of number sense and quantifier interpretation.
We show, further, that impairment of number sense in patients can result in the impairment of the ability to interpret sentences
containing quantifiers. This result demonstrates that number sense supports some aspects of the language faculty.

The effect of Parkinson's disease on time estimation as a function of stimulus duration range and modality 总被引:2,自引:0,他引:2
The present research sought to investigate the role of the basal ganglia in timing of sub- and supra-second intervals via an examination of the ability of people with Parkinson's disease (PD) to make temporal judgments in two ranges, 100-500 ms, and 1-5 s. Eighteen non-demented medicated patients with PD were compared with 14 matched controls on a duration-bisection task in which participants were required to discriminate auditory and visual signal durations within each time range. Results showed that patients with PD exhibited more variable duration judgments across both signal modality and duration range than controls, although closer analyses confirmed a timing deficit in the longer duration range only. The findings presented here suggest the bisection procedure may be a useful tool in identifying timing impairments in PD and, more generally, reaffirm the hypothesised role of the basal ganglia in temporal perception at the level of the attentionally mediated internal clock as well as memory retrieval and/or decision-making processes. 相似文献

Studies have reported a right visual field (RVF) advantage for coherent motion detection by deaf and hearing signers but not non-signers. Yet two studies [Bosworth R. G., & Dobkins, K. R. (2002). Visual field asymmetries for motion processing in deaf and hearing signers. Brain and Cognition, 49, 170-181; Samar, V. J., & Parasnis, I. (2005). Dorsal stream deficits suggest hidden dyslexia among deaf poor readers: Correlated evidence from reduced perceptual speed and elevated coherent motion detection thresholds. Brain and Cognition, 58, 300-311.] reported a small, non-significant RVF advantage for deaf signers when short duration motion stimuli were used (200-250 ms). Samar and Parasnis (2005) reported that this small RVF advantage became significant when non-verbal IQ was statistically controlled. This paper presents extended analyses of the correlation between non-verbal IQ and visual field asymmetries in the data set of Samar and Parasnis (2005). We speculate that this correlation might plausibly be driven by individual differences either in age of acquisition of American Sign Language (ASL) or in the degree of neurodevelopmental insult associated with various etiologies of deafness. Limited additional analyses are presented that indicate a need for further research on the cause of this apparent IQ-laterality relationship. Some potential implications of this relationship for lateralization studies of deaf signers are discussed. Controlling non-verbal IQ may improve the reliability of short duration coherent motion tasks to detect adaptive dorsal stream lateralization due to exposure to ASL in deaf research participants. 相似文献

Rapid processing deficits have been the subject of much debate in the literature on specific language impairment (SLI). Hari and Renvall (2001) [Hari, R. & Renvall, H. (2001). Impaired processing of rapid stimulus sequences in dyslexia. Trends in cognitive sciences, 5, 525-532.] proposed that the source of this deficit can be attributed to sluggish attentional shifting abilities. That is, more time is required to shift attention between stimuli. To test this claim, 26 adolescents with SLI (divided into two subgroups to control for differences in non-verbal intelligence) and 14 controls were presented with a rapid serial visual presentation task. In this task participants were asked to detect two visual targets presented serially with distracter items with varying inter-target intervals (i.e., time difference between targets). This task was designed to elicit an attentional blink (AB). The AB describes the phenomenon whereby non-impaired individuals are less likely to report the second of two targets presented within 200-500ms of each other. After controlling for group differences in non-verbal intelligence, the SLI group was found to be significantly less accurate than the control group at successfully reporting the second target at inter-target intervals of 100, 200, 300, 400 and 800ms. The results were interpreted to suggest that adolescents with language impairments have an AB which differs from non-impaired individuals in both magnitude and duration. 相似文献

ABSTRACT— Despite evidence for memory skill early in development, the evidence reviewed here shows that early-acquired memories, in rats and humans, are frozen in time. That is, in the absence of opportunities for updating, early memories are only expressed via responses or words that were available at the time of encoding. We discuss the theoretical importance of these findings and their potential clinical and forensic implications. 相似文献

本研究旨在探讨以汉语为第二语言的学习者在提取汉字语义时是否受到形音信息的影响。实验以16名在华的韩国留学生作为被试,采用句尾歧义字实验范式,句尾字包括四种条件——符合句义的目标字、目标字的同音字、目标字的形近字和无关控制字,后三种类型的句尾字构成了歧义句。被试的任务是判断句义是否正确。实验结果发现,被试对同音干扰字的反应时明显短于对形近干扰字的反应时,对同音干扰字的判断正确率显著高于对形近干扰字和无关控制字的判断正确率,而形近干扰字和无关控制字无论在正确率还是反应时上均没有显著差异。这个结果表明,以汉语作为第二语言的韩国留学生在阅读汉语时,汉字的语音信息自动激活,并促进语义的提取。 相似文献

Abstract : A personal account of an analysis with Michael Fordham and subsequent conversations with James Astor. A number of themes are developed concerning the expression of feeling, use of language, and the relevance of aesthetic values to the practice and reporting of analysis. 相似文献

Even though Questions Answering and Database Querying have very different goals and frameworks, collaboration between the two fields could be mutually beneficial. However, the different assumptions in each field makes such collaboration difficult. In this paper, we introduce a query language with generalized quantifiers (QLGQ) and show how it could be used to help bridge the gap between the two fields. 相似文献
