Following hemispherectomy, patients performing dichotic listening tasks have great difficulty reporting items presented to the ear ipsilateral to their intact hemisphere. One possible cause is an attentional imbalance which, when competing inputs are received from both sides of space, restricts the patient's attention to the stimulus contralateral to his remaining hemisphere. If this explanation is true, then a similar ipsilateral ear decrement should occur when a competing visual stimulus is presented in the contralateral field. In the present study, however, hemispherectomy patients easily reported a digit presented to the ear ipsilateral to their intact hemisphere despite the concurrent presentation of a visual digit to their contralateral field. 相似文献

Alpha hemispheric asymmetries of nonstuttering males, nonstuttering females, and stuttering males were explored with electroencephalographic procedures during exposure to two lists of one-syllable words which the subjects were required to recall following presentation. One word list contained low-imagery words while the other contained high-imagery words. Stuttering males were found to have significantly less alpha in their right hemispheres, suggesting right hemispheric processing strategies. This finding was interpreted as supporting the “segmentation dysfunction” explanation of stuttering suggested by Moore and Haynes (1979b). Nonstuttering males showed less left than right alpha while nonstuttering females revealed no difference between their right and left hemispheres. Differences between nonstuttering males and females are discussed as being task and stimuli dependent relative to the segmental/nonsegmental nature of both task and stimuli. Differential hemispheric asymmetries for words of high or low-imagery were not observed. 相似文献

Right hemisphere appreciation of prosodic and linguistic indications of implicit attitude 总被引:4,自引:1,他引:3
Appreciation of attitudes conveyed through prosodic cues and lexical content was examined in subjects with temporal lobe seizure foci. One task involved auditory judgments of the consistency of verbal and intonational meaning of sentences. Errors on judgments of consistent verbal and prosodic stimuli were not only more frequent in the right temporal group than in left temporals or controls but were strongly related to neuropsychological indices associated with extent of right temporal involvement. Answering questions based on written narratives in which multiple attitude markers were either redundant or conflicting comprised the second task. Right temporal patients as a group had difficulty in answering inferential questions about paragraphs with inconsistent indicators of attitude. Even low-scoring right temporals were able, however, to answer inferential and factual questions when the verbal context markers consistently reinforced a particular attitude. 相似文献

This case report describes an unusual combination of speech and language deficits secondary to bilateral infarctions in a 62-year-old woman. The patient was administered an extensive series of speech, language, and audiologic tests and was found to exhibit a fluent aphasia in which reading and writing were extremely well preserved in comparison to auditory comprehension and oral expression, and a severe auditory agnosia. In spite of her auditory processing deficits, the patient exhibited unexpected self-monitoring ability and the capacity to form acoustic images on visual tasks. The manner in which she corrected and attempted to correct her phonemic errors, while ignoring semantic errors, suggests that different mechanisms may underlie the monitoring of these errors. 相似文献

"文"是中国古代文化研究中的一个关键词,值得引起学术界的足够重视。本文借鉴梭罗和杜威两位美国思想家的智慧,对在《周易·系辞》中出现的"文"的意义和用法进行了深入的探讨。本文认为,"文"体现了中国古代先哲对于真理锲而不舍的追求及其所取得的成就,而这不论是对于我们认识《周易》本身的价值,还是对中国当下的文化研究和文化建设,都具有不可忽视的意义。 相似文献

Lexical innovation--the creation of a word by combining existing morphemes in a novel way (e.g. "map ball" for "globe")--was evaluated as a method for circumventing word-finding difficulty in Broca's and Wernicke's aphasia. Aphasic groups were matched for naming performance and compared to a control group of normal adults matched for age and education. Lexical innovations were collected during the administration of a confrontation naming test, and were then analyzed in terms of the correctness of morpheme combination, semantic accuracy, novelty, and communicative effectiveness. An innovation was considered to be communicatively effective when its intended referent was understood by a naive judge. The lexical innovations of the two aphasic groups were diametrically opposed: as compared to both Broca's aphasics and normal adults, Wernicke's aphasics innovated significantly less often, and their innovations were significantly inferior in terms of: semantic precision, the proper construction of morpheme combination, and communicative effectiveness. This pattern suggests that lack of verbal fluency may be compatible with lexical creativity, while empty logorrheic speech may be an impediment to lexical creativity. Similarly, we conclude that the agrammatism of Broca's asphasia does not interfere with lexical innovation, while the paragrammatism of Wernicke's aphasia does interfere with lexical innovation, thus suggesting that paragrammatism affects morpheme combination at the word level as well as the sentence level. 相似文献

Kenneth M. George 《The Journal of religious ethics》2016,44(1):51-67
Just as recognition and pursuit of the human good take place in language and action, so too do they unfold in encounter with the material and visual. The ethical crises, projects, and striving we see in everyday religious life are worked out not just in the intersubjective play and politics of language but also in encounter with, in dwelling with, material and visual substances and forms. This essay considers the material conditions that make possible the “ethical pleasures” sought by Indonesian painter A. D. Pirous in making and displaying contemporary works of “Islamic art,” most especially works that make “visual recitation” of passages from the Qur'an. 相似文献

One of the most compelling questions still unanswered in neuroscience is how consciousness arises. In this article, we examine visual processing, the parietal lobe, and contralateral neglect syndrome as a window into consciousness and how the brain functions as the mind and we introduce a mechanism for the processing of visual information and its role in consciousness. We propose that consciousness arises from integration of information from throughout the body and brain by the thalamus and that the thalamus reimages visual and other sensory information from throughout the cortex in a default three-dimensional space in the mind. We further suggest that the thalamus generates a dynamic default three-dimensional space by integrating processed information from corticothalamic feedback loops, creating an infrastructure that may form the basis of our consciousness. Further experimental evidence is needed to examine and support this hypothesis, the role of the thalamus, and to further elucidate the mechanism of consciousness. 相似文献

Study the role of intellectual property protection in advanced manufacturing SMEs. Is it to protect the growth of advanced manufacturing SMEs, or to inhibit the growth of SMEs in advanced manufacturing? the paper brings the medium variable – technological innovation to explore acting paths of intellectual property protection in enterprises’ value improvement. Through analysis of panel data of 80 SMEs of advanced manufacture collected during the period from 2013 to 2015, Research results show that as for SMEs of advanced manufacture, the inverted-U relationship still exists in the influences brought by intellectual property protection to enterprise values. Meanwhile, U-shaped relations exist between intellectual property protection and technological innovation. Increase of technological innovation investment can promote increase of enterprise values. 相似文献
