生命性的范畴化从多个方面影响了语言的加工.名词的生命性信息不仅影响了句法形态标记和句法位置等句法线索的使用,而且在题元角色的分配中发挥一定的作用.较早的研究主要采用反应时和眼动技术,发现生命性信息促进了歧义句和句法复杂句的加工.近年来,随着认知神经科学技术的发展,研究者进一步探讨了生命性信息在题元角色分配中的神经机制.对于生命性作用机制的深入研究,促使新的语言加工模型的出现,这些模型对语言加工中句法和语义的关系,进行了越来越详尽的阐释.未来该领域的研究应重点关注生命性的即时性加工、题元角色分配中生命性信息与句法信息的交互作用以及汉语和其他语言的跨语言比较研究等,以进一步揭示语言加工的认知机制. 相似文献

We measured Chinese dyslexic and control children's eye movements during rapid automatized naming (RAN) with alphanumeric (digits) and symbolic (dice surfaces) stimuli. Both types of stimuli required identical oral responses, controlling for effects associated with speech production. Results showed that naming dice was much slower than naming digits for both groups, but group differences in eye‐movement measures and in the eye–voice span (i.e. the distance between the currently fixated item and the voiced item) were generally larger in digit‐RAN than in dice‐RAN. In addition, dyslexics were less efficient in parafoveal processing in these RAN tasks. Since the two RAN tasks required the same phonological output and on the assumption that naming dice is less practiced than naming digits in general, the results suggest that the translation of alphanumeric visual symbols into phonological codes is less efficient in dyslexic children. The dissociation of the print‐to‐sound conversion and phonological representation suggests that the degree of automaticity in translation from visual symbols to phonological codes in addition to phonological processing per se is also critical to understanding dyslexia. 相似文献

This paper explores the process through which children sort out the relations among verbs belonging to the same semantic domain. Using a set of Chinese verbs denoting a range of action events that are labeled by carrying or holding in English as a test case, we looked at how Chinese-speaking 3-, 5-, and 7-year-olds and adults apply 13 different verbs to a range of carrying/holding events. We asked how children learning Chinese originally divide and label the semantic space in this domain, how they discover the boundaries between different words, and how the meanings of verbs in the domain as a whole evolve toward the representations of adults. We also addressed the question of what factors make verb meaning acquisition easy or hard. Results showed that the pattern of children’s verb use is largely different from that of adults and that it takes a long time for children to be able to use all verbs in this domain in the way adults do. We also found that children start to use broad-covering and frequent verbs the earliest, but use of these verbs tends to converge on adult use more slowly because children could not use these verbs as adults did until they had identified boundaries between these verbs and other near-synonyms with more specific meanings. This research highlights the importance of systematic investigation of words that belong to the same domain as a whole, examining how word meanings in a domain develop as parts of a connected system, instead of examining each word on its own: learning the meaning of a verb invites restructuring of the meanings of related, neighboring verbs. 相似文献

心理模拟在语言理解中的作用逐渐受到人们重视。相关理论包括知觉符号系统理论、语言的神经理论和语言与情境模拟理论。行为研究发现感知觉运动信息与语言理解存在交互作用,而脑机制研究显示感知觉运动脑区参与语言理解。目前的研究对于心理模拟参与语言理解的机制仍缺乏细致探讨,导致结果存在矛盾之处。对隐喻语言里心理模拟作用的探讨也需加强。此外,心理模拟系统如何与语言学信息交互作用的相关假设也需要完善。 相似文献

In alphabetic writing systems, saccade amplitude (a close correlate of reading speed) is independent of font size, presumably because an increase in the angular size of letters is compensated for by a decrease of visual acuity with eccentricity. We propose that this invariance may (also) be due to the presence of spaces between words, guiding the eyes across a large range of font sizes. Here, we test whether saccade amplitude is also invariant against manipulations of font size during reading Chinese, a character-based writing system without spaces as explicit word boundaries for saccade-target selection. In contrast to word-spaced alphabetic writing systems, saccade amplitude decreased significantly with increased font size, leading to an increase in the number of fixations at the beginning of words and in the number of refixations. These results are consistent with a model which assumes that word beginning (rather than word center) is the default saccade target if the length of the parafoveal word is not available. 相似文献

Failure to initiate and remain engaged in academic tasks can have long-lasting effects for students. In this study, we investigated the effects of high-preference sequences on both digits correct per minute and latency to initiate nonpreferred mathematics problems for 3 students with emotional and behavioral disorders. We found that high-preference sequences had negligible positive effects on rate of problem completion but had larger effects on problem initiation. This study replicates and extends prior work on the effects of high-preference sequences on mathematics problem initiation and completion. 相似文献

Depressed women with sexual abuse histories have a heightened risk of suicidal ideation (SI), which may be only in part attributable to psychiatric symptoms of depression and posttraumatic stress disorder (PTSD). Emotions and SI were studied among 106 women with histories of childhood sexual abuse enrolled in treatment trials for major depression. Assessments were conducted at baseline, 10, 24, and 36 weeks. Sadness, guilt, and shame-proneness were associated with self-reported and observer-rated SI across time after adjusting for depressive and PTSD symptoms, suicide attempt history, and sociodemographic characteristics associated with SI. These findings highlight the need for clinical attention to self-directed negative emotions to potentially reduce suicide-related risk. 相似文献
