动词语义和句子语法对代词加工的影响   总被引:6,自引:1,他引:5  
考察了动词语义和句子语法对代词加工的影响.结果表明,动词语义是影响代词理解的一个因素;相同语法功能假设尚需进一步验证,研究者还提出代词理解受社会文化因素影响的假设。  相似文献

犹太人只要交纳必需的赋税,只要不威胁国家安全,罗马政府就允许他们按照其祖先的律法生活。犹太人虽然不拥有完全的自治权,但有权裁决内部纠纷,其宗教自由也能够得到罗马政权的保障和宽容。自恺撒为这种政策奠定恰当的法律形式以来,它在基督教获得全面胜利以前具有很强的稳定性。由于有关犹太人的文献在罗马世界的地方文献中保存得最好,考察罗马的犹太政策为我们了解罗马的宗教政策和民族政策提供了独特的视角。  相似文献

ABSTRACT

Sequential modulations in symbolic cueing tasks have been attributed to complete versus partial repetition/alternation of stimulus features between consecutive trials. This feature-integration hypothesis is questioned by recent findings and further investigated in the present study. In the first two experiments, when the cueing axes switched between trials, only complete alternation of cue directions and target locations existed. Nevertheless, significant sequence effects were still found in this condition, which did not support the feature-integration hypothesis. Furthermore, although sequence effects were still significant when stimulus identities were manipulated in Experiment 3, it was abolished when different cue categories (gaze and arrow) were presented as cues in Experiment 4. The findings suggest that the integration of stimulus features is not the only source of the sequential effect and some higher level cognitive mechanisms, possibly as described in the task-file or task organization hypotheses, are involved in the sequential modulations of symbolic cueing.  相似文献

Humans conduct visual search more efficiently when the same display is presented for a second time, showing learning of repeated spatial contexts. In this study, we investigate spatial context learning in two tasks: visual search and change detection. In both tasks, we ask whether subjects learn to associate the target with the entire spatial layout of a repeated display (configural learning) or with individual distractor locations (nonconfigural learning). We show that nonconfigural learning results from visual search tasks, but not from change detection tasks. Furthermore, a spatial layout acquired in visual search tasks does not enhance change detection on the same display, whereas a spatial layout acquired in change detection tasks moderately enhances visual search. We suggest that although spatial context learning occurs in multiple tasks, the content of learning is, in part, task specific.  相似文献

In Korea, two number systems are in simultaneous use. One is somewhat irregular (like the English language number system), and the other regular (similar to the Chinese number system). This natural experiment allows a direct test of the hypothesis that structural regularity of the number system facilitates the acquisition of counting. Korean children initially suffer from their numerical ‘bilingualism’: they find it difficult to learn two counting systems at the same time. Yet, after this initial difficulty, they soon master the generative rules which are transparent in the regular system. The cognitive advantage provided by the regular number system then combines with other factors, like intensive teaching and parental pressure, to produce school achievement in mathematics superior to US children's.  相似文献

Operant devices have been used for many years in animal behavior research, yet such devices a regenerally highly specialized and quite expensive. Although commercial models are somewhat adaptable and resilient, they are also extremely expensive and are controlled by difficult to learn proprietary software. As an alternative to commercial devices, we have designed and produced a fully functional, programmable operant device, using a PICmicro microcontroller (Microchip Technology, Inc.). The electronic operant testing apparatus (ELOPTA) is designed to deliver food when a study animal, in this case a bird, successfully depresses the correct sequence of illuminated keys. The device logs each keypress and can detect and log whenever a test animal i spositioned at the device. Data can be easily transferred to a computer and imported into any statistical analysis software. At about 3% the cost of a commercial device, ELOPTA will advance behavioral sciences, including behavioral ecology, animal learning and cognition, and ethology.  相似文献

未来思考是前瞻性思考,旨在解决人生发展任务。人类的未来思考有多种类型。从是否具有现实性上来看,可以把未来思考分为两种主要形式:期望和幻想。幻想抑制动机和行为,但是,如果对幻想和不利现实因素进行心理对照,幻想就可以转变成执行性意图,这是因为心理对照过程能够产生美好未来和当前现实的同时通达。我们还探讨了习惯于不同自我监控思维模式的人对待时间、失败的人格差异,并提出了进一步的研究方向。  相似文献

Recently, it has been recognized that the commonly used linear structural equation model is inadequate to deal with some complicated substantive theory. A new nonlinear structural equation model with fixed covariates is proposed in this article. A procedure, which utilizes the powerful path sampling for computing the Bayes factor, is developed for model comparison. In the implementation, the required random observations are simulated via a hybrid algorithm that combines the Gibbs sampler and the Metropolis-Hastings algorithm. It is shown that the proposed procedure is efficient and flexible; and it produces Bayesian estimates of the parameters, latent variables, and their highest posterior density intervals as by-products. Empirical performances of the proposed procedure such as sensitivity to prior inputs are illustrated by a simulation study and a real example.This research is fully supported by a grant from the Research Grant Council of the Hong Kong Special Administrative Region, China (Project No. CUHK 4346/01H). The authors are thankful to the Editor, the Associate Editor, and anonymous reviewers for valuable comments which improve the paper significantly, and grateful to ICPSR and the relevant funding agency for allowing use of the data in the example. The assistance of Michael K.H. Leung and Esther L.S. Tam is gratefully acknowledged.  相似文献
