Stefano Predelli 《Journal of Philosophical Logic》2008,37(3):277-297
This paper argues in favor of a treatment of discourse about fiction in terms of operators on character, that is, Kaplanesque
‘monsters’. The first three sections criticize the traditional analysis of ‘according to the fiction’ as an intensional operator,
and the approach to fictional discourse grounded on the notion of contextual shifts. The final sections explain how an analysis
in terms of monsters yields the correct readings for a variety of examples involving modal and temporal indexicals. 相似文献

Kormi-Nouri, Moniri and Nilsson (2003) demonstrated that Swedish-Persian bilingual children recalled at a higher level than Swedish monolingual children, when they were tested using Swedish materials. The present study was designed to examine the bilingual advantage of children who use different languages in their everyday life but have the same cultural background and live in their communities in the same way as monolingual children. In four experiments, 488 monolingual and bilingual children were compared with regard to episodic and semantic memory tasks. In experiments 1 and 2 there were 144 boys and 144 girls in three school groups (aged 9-10 years, 13-14 years and 16-17 years) and in three language groups (Persian monolingual, Turkish-Persian bilingual, and Kurdish-Persian bilingual). In experiments 3 and 4, there were 200 male students in two school groups (aged 9-10 years and 16-17 years) and in two language groups (Persian monolingual and Turkish-Persian bilingual). In the episodic memory task, children learned sentences (experiments 1-3) and words (Experiment 4). Letter and category fluency tests were used as measures of semantic memory. To change cognitive demands in memory tasks, in Experiment 1, the integration of nouns and verbs within sentences was manipulated by the level of association between verb and noun in each sentence. At retrieval, a recognition test was used. In experiments 2 and 3, the organization between sentences was manipulated at encoding in Experiment 2 and at both encoding and retrieval in Experiment 3 through the use of categories among the objects. At retrieval, free recall or cued recall tests were employed. In Experiment 4, the bilingual children were tested with regard to both their first and their second language. In all four experiments, a positive effect of bilingualism was found on episodic and semantic memory tasks; the effect was more pronounced for older than younger children. The bilingual advantage was not affected by changing cognitive demands or by using first/second language in memory tasks. The present findings support the cross-language interactivity hypothesis of bilingual advantage. 相似文献

“语义错觉效应”是指读者在加工某些语义违例句子时,会暂时性地产生语义合理错觉,而只有通过继续加工或者再加工才能辨别出错误的现象,在脑电成分上表现为没有出现N400效应,却出现P600效应。“语义错觉效应”对传统的句子加工理论模型以及N400和P600的特异性功能意义提出了质疑。研究者在讨论此效应的基础上提出了多个句子加工模型,各模型对语义和句法加工的过程进行了探索,对语义和句法通道的关系做出了新的阐述,并对N400和P600的功能意义做出了新的解读。目前研究对N400功能的解释存在语义整合观和词汇激活观的分歧,而对P600功能的解释则从传统的句法功能转换到了更宽泛的加工过程。未来研究应关注词汇语义关系和跨语言差异,以期进一步揭示句子加工的认知及神经机制。 相似文献

4~7岁儿童绘画摹写的语义编码特点 总被引:2,自引:0,他引:2
以二维模型为主对儿童绘画编码特点及发展进程的探讨。研究对象为4—7岁儿童,按年龄分为4组,共163人。主要实验有二:一是选择同一实物的三维和二维两类模型让被试摹写;二是选择语义熟悉程度和语义多寡不同的二维模型让被试摹写。个别实验,实验顺序随机安排。研究结果表明:儿童对维度不同的模型绘画编码具有共同的特点,表现出三种编码形式:其一,将模型的各构件分离,各自独立编码;其二,依模型的典型特征编码;其三,按各模型真实形象编码。儿童对不同维度模型绘画编码发展的进程不同。对二维模型绘画编码水平和发展速度比三维模型提早1年。模型语义的多寡及熟悉程度影响儿童二维模型绘画编码。 相似文献

Self-focused attention has been found to facilitate task performance in some instances and inhibit it in others. Among chronically anxious individuals it appears to consistently hinder performance. Less is known about the impact of self-focus on the performance of normal individuals. The present study examines the role of task difficulty, task self-relevance, and presence of evaluation anxiety in the performance effects of self-focus among normal individuals. Participants performed a simple reaction time (RT) and a lexical decision task, in Experiments 1 and 2, respectively, with or without self-focus. Self-focus and evaluation anxiety resulted in faster responding in simple RT, but there was no significant effect of self-focus on performance in the more difficult lexical decision task. Participants' heart rate (HR) was monitored and indicated that orienting was associated with slower RT in both experiments, and less orienting was found during self-focus and evaluation conditions. Results are interpreted in light of several self-focus theories. 相似文献

该研究采用眼动追踪技术和分心阅读范式考察了句子理解中的抑制过程,以及外在干扰信息的性质如何影响阅读中的抑制效率。研究结果发现语义相关干扰词比语义无关干扰词的阅读时间、注视时间更长,注视次数更多。语义无关干扰词比无意义字符串的注视时间更长、注视次数更多。该结果说明阅读过程中干扰信息越有意义,与目标句语义联系越紧密,则越容易被激活,抑制效率也就越低,符合Hasher等人提出的一般认知过程中抑制加工的原理。 相似文献

作者通过实验考察了大学生被试对五种充分条件句语义关系知觉对其条件推理的影响。两个实验的结果表明,被试对条件句中前后件之间语义关系的知觉理解影响和调节其相应的条件推理的成绩。实验1新发现,被试对充分条件句后件对前件必要性的知觉理解存在难易差异,对许可句和定义句的后件必要性容易知觉,对偶然句、义务句和因果句的后件必要性难以知觉。实验2新发现,被试对充分条件句后件对前件必要性的知觉理解的难易差异导致被试在否定后件式推理成绩上的差异,对许可句和定义句的否定后件式推理成绩显著高于对偶然句、义务句和因果句的否定后件式推理成绩,对充分条件句否定后件式推理成绩随对后件必要性知觉增加而增加。 相似文献
