Earlier studies have examined the issues of brain spatial localization in human sentential inductive reasoning using PET/fMRI. However, the temporal characteristics of such reasoning remain unclear. In our present study, we have used ERP (Event-related Potential) to further study human inductive reasoning involving sentential tasks. For congruent induction tasks, in which premises and conclusions are related, participants need to synthesize semantic information from the premises, conclusions, as well as background knowledge, while for incongruent induction tasks (baseline), in which premises and conclusions are unrelated, participants can respond “no” immediately. Behavioral data have been obtained that is consistent with expectations. ERPs imply that participants may integrate semantic information within the time window of 350–650 ms. Statistical analysis in the frequency domain has revealed a significant increase in the power of the gamma band (30–50 Hz) for congruent induction tasks in contrast to incongruent induction tasks. 相似文献

Using the event-related potential (ERP) technique, this study examined the nature of syntactic priming effects in Chinese. Participants were required to read prime-target sentence pairs each embedding an ambiguous relative clause (RC) containing either the same verb or a synonymous verb. In Chinese, the word de serves as a relative clause marker. During reading a potential Chinese RC structure (either the prime or the target sentence), Chinese readers initially expect to read an Subject–Verb–Object (SVO) structure but the encounter of a relative clause marker de would make readers abandon the initial strategy and reanalyze the structure as a relative clause. A reduced P600 effect was elicited by the critical word de in the target sentence containing the same initial verb as in the prime sentence. No significant reduction of the P600 was observed in the target sentences in the synonymous condition. The results demonstrated that verb repetition but not similarity in meaning produced a syntactic priming effect in Chinese. The constraint-based lexicalist hypothesis and the argument structure theory were adopted to explain the syntactic priming effect obtained in the current study. 相似文献

通过统计模拟的数据分析发现:当以置信区间表示研究结果时,元分析的价值简单地表现为置信区间宽度的减小。在统计推断方面,这种区间宽度的减小会使得元分析能够通过降低样本观察值落在中间模糊区域的概率而提高检验效力;在效应估计方面,这种区间宽度的减小能够稳定地反映由元分析而促成的效应估计精度的增加。研究还揭示:当以置信区间表示研究结果时,元分析和单项研究在逻辑上是连贯的。 相似文献

For testlet response data, traditional item response theory (IRT) models are often not appropriate due to local dependence presented among items within a common testlet. Several testlet‐based IRT models have been developed to model examinees' responses. In this paper, a new two‐parameter normal ogive testlet response theory (2PNOTRT) model for dichotomous items is proposed by introducing testlet discrimination parameters. A Bayesian model parameter estimation approach via a data augmentation scheme is developed. Simulations are conducted to evaluate the performance of the proposed 2PNOTRT model. The results indicated that the estimation of item parameters is satisfactory overall from the viewpoint of convergence. Finally, the proposed 2PNOTRT model is applied to a set of real testlet data. 相似文献

Graham Priest 2002 argues that all logical paradoxes that include set-theoretic paradoxes and semantic paradoxes share a common structure, the Inclosure Schema, so they should be treated as one family. Through a discussion of Berry's Paradox and the semantic notion ‘definable’, I argue that (i) the Inclosure Schema is not fine-grained enough to capture the essential features of semantic paradoxes, and (ii) the traditional separation of the two groups of logical paradoxes should be retained. 相似文献

强化治疗是最近几年反复提到的话题。很多临床试验研究各种强化治疗对心血管疾病预后的影响,但结果显示强化治疗并未能带来更多的益处,甚至有害。因此我们必须理性地看待这些所谓的强化治疗。更应该倾向于个体化治疗、综合治疗,包括控制各种危险因素,改善生活的方式。把治疗的眼光放到疾病发生的早期,早治疗,以求更多获益。 相似文献

个人能具备美德是人们都能理解的,但制度能具备美德却是需要加以严密论证的.在当代社会中,制度具备美德是一种普遍的诉求,正义是社会制度的美德,而且是首要美德.在一个具备了正义秩序和正义美德的社会制度中,社会才能获得发展的前提,个人才能合理追求自己的幸福,同时其他美德也能得以塑造成型. 相似文献

全真道在王重阳创教初期,只是一个民间"隐修会",屡受金廷的打压甚至罢禁.至丘处机出任第五代掌教时,因得到蒙古国成吉思汗的尊崇而逐步走向兴盛.在丘处机等全真高道的努力下,全真道的经济实力日益壮大,教团管理日趋成熟,戒律体系和官观管理规制不断完善,遂道由组织松散的民间宗教逐渐转变为戒规完备、管理成制的官方宗教. 相似文献
