摘要

认知体现在语言、知觉、运动和情感系统中的多模态方法是概念表征的一个广泛认可的理论框架。然而，在健康和病理性衰老中，缺乏支持这一认知观点的工作，这与了解揭示脑病理中语义退化的因素的持续需求形成鲜明对比。本研究的目的是探讨感知强度(PS)的影响，即一个单词可以被多种感觉模式体验的程度，在阿尔茨海默病(AD)的视觉单词识别。36名健康受试者、22名轻度AD阶段受试者(AD1)和20名中度AD阶段受试者(AD2)分别参与高PS词和低PS词两种条件下的词汇决策任务。结果显示，只有健康对照组和AD1个体之间存在交互作用，后者处理高PS词的速度比处理低PS词的速度快，而健康个体则没有这种情况。此外，正是神经心理执行和词汇语义评估的评分预测了这些结果。然而，对于AD2的参与者，没有观察到任何结果，这表明词汇语义的退化过于严重，无法揭示PS效应。本研究证明了在检查概念系统时考虑感知维度的重要性，并为阿尔茨海默病的语义损伤探索开辟了新的途径。

期刊介绍： The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
