Infants younger than 20 months of age interpret both words and symbolic gestures as object names. Later in development words and gestures take on divergent communicative functions. Here, we examined patterns of brain activity to words and gestures in typically developing infants at 18 and 26 months of age. Event-related potentials (ERPs) were recorded during a match/mismatch task. At 18 months, an N400 mismatch effect was observed for pictures preceded by both words and gestures. At 26 months the N400 effect was limited to words. The results provide the first neurobiological evidence showing developmental changes in semantic processing of gestures. 相似文献

In this paper I propose a model of metaphor interpretation that would account for the possibility that semantic processing of familiar metaphors no longer go through the sequential steps of alignment and projection, but may rather be established upon schematic semantic units allowing faster processing. The proposition is grounded on the notion that metaphors are formed based on peoples’ perception of what is typically associated with entities. It is suggested that in its most abstract form, these associations are essentially events, analyzed in terms of event structure. 相似文献

医学和哲学都是人类发展历史中的重要学科,随着医学模式的改变,微创医学作为医学的新兴理念迅猛发展.但是哲学作为最高科学,依然指导了微创医学的发展.手术范围的变迁、有所为有所不为、主要矛盾与次要矛盾的转变、否定之再否定等哲学理念都在微创医学的发展中得以体现.微创医学的发展,对外科医师提出更高的要求. 相似文献

汉字加工的基本单元:来自笔画数效应和部件数效应的证据 总被引:30,自引:8,他引:22
用命名作业和真假字判断作业考察了笔画数和部件数对汉字加工的影响,发现,当部件数保持恒定时,笔画数少的汉字较笔画数多的汉字加工快,这种笔画数效应和字频之间不存在交互作用;当笔画数被控制时,部件数效应也存在,但和字频有交互作用,表现在低频少部件汉字的加工要快于低频多部件汉字的加工,而高频汉字中的部件数效应不显著。实验还发现独体字(只有一个部件)的加工和合体字(部件数大于等于二)的加工有差异。作者认为,汉字的加工要经过笔画、部件和整字三个层次,其中单位部件的笔画数和部件数影响着汉字加工时间 相似文献

This article explores the implications of the prevalence of suicide attacks or ‘martyrdom operations’ in contemporary Islam. Historical and legal precedents from Islam and Christianity are adduced for the analysis and placed within the context of radical Islam. 相似文献

We examined whether semantic processing occurs without awareness using continuous flash suppression (CFS). In two priming tasks, participants were required to judge whether a target was a word or a non-word, and to report whether the masked prime was visible. Experiment 1 manipulated the lexical congruency between the prime-target pairs and Experiment 2 manipulated their semantic relatedness. Despite the absence of behavioral priming effects (Experiment 1), the ERP results revealed that an N4 component was sensitive to the prime-target lexical congruency (Experiment 1) and semantic relatedness (Experiment 2) when the prime was rendered invisible under CFS. However, these results were reversed with respect to those that emerged when the stimuli were perceived consciously. Our findings suggest that some form of lexical and semantic processing can occur during CFS-induced unawareness, but are associated with different electrophysiological outcomes. 相似文献

We study the semantic relationship between pairs of nouns of concrete objects such as “HORSE - SHEEP” and “SWING - MELON” and how this relationship activity is reflected in EEG signals. We collected 18 sets of EEG records; each set containing 150 events of stimulation. In this work we focus on feature extraction algorithms. Particularly, we highlight Common Spatial Pattern (CSP) as a method of feature extraction. Based on these latter, different classifiers were trained in order to associate a set of signals to a previously learned human answer, pertaining to two classes: semantically related, or not semantically related. The results of classification accuracy were evaluated comparing with other four methods of feature extraction, and using classification algorithms from five different families. In all cases, classification accuracy was benefited from using CSP instead of FDTW, LPC, PCA or ICA for feature extraction. Particularly with the combination CSP-Naïve Bayes we obtained the best average precision of 84.63%. 相似文献

涎腺肌上皮癌是一种发生于涎腺的罕见恶性肿瘤,随着研究的深入,对其生物学行为及治疗争议较大,其中牵涉到很多矛盾的思想观点,如涎腺肌上皮癌的恶性程度与分型,诊断,颈淋巴清扫的选择,术后辅助放化疗的选择等。本文对其中所蕴涵的哲学思想进行反思,以期引导对涎腺肌上皮癌的科学认识。 相似文献

We examine semantic conditioning in a consumer context. We subliminally paired neutral ideographs with attributes. In experiment 1, the ideographs served as primes during a lexical decision task and slowed down response times to target words with the opposite semantic meaning. In experiment 2, the ideographs served as brand names of beverages, and attitudinal responses to them were less favorable when the associated attributes were incongruent with existing schemas. These results showed that semantic conditioning (1) can occur unconsciously, (2) can have significant and meaningful consequences for brand evaluation, and (3) influences subsequent attitudinal responses via conceptual disfluency processes. 相似文献

本文在阐明詹姆斯心理学的出发点、并考察其心理学思想的探索和突破的基础上指出,詹姆斯关于心理学的思想历程无疑经历了一个根本的转向;又结合与胡塞尔现象学的比较认为,转向之后的詹姆斯的心理学思想的潜在意义,只有借用胡塞尔现象学的思想框架和概念工具,才能得到有效的表达和进一步的发展。文章最后还暗示了詹姆斯心理学思想的现象学转向对于理解并构建心理学的学科同一性的潜在意义。 相似文献
