与年龄相关的语言处理能力下降在一定程度上归因于普遍的认知放缓。由于这种放缓,有人认为老年人的句子理解可能会通过降低说句子的速度来促进。然而,研究并没有可靠地表明慢语速能提高理解能力。目前的研究探索了一种假设,即工作记忆(WM)的下降实际上会抵消语言速度下降带来的任何好处。也就是说,在比正常语速慢的情况下,由于信息必须在更长的时间内保留,因此对WM提出了更多的要求。对三名阿尔茨海默病患者的正常和慢速语言的理解能力进行了测试,每个人都表现出独特的WM能力。结果表明,语速对理解能力的影响取决于语速的大小:语速慢只对语速保存最完整的被试有益;语速不影响…
Abstract Age-related declines in language processing have been attributed in part to generalized cognitive slowing. Because of this slowing, it has been suggested that older adults' sentence comprehension might be facilitated by reducing the rate at which sentences are spoken. Research, however, has failed to reliably show that speaking slowly enhances comprehension. the present study explores the hypothesis that declines in working memory (WM) would actually counteract any benefits derived from a reduction in speech rate. That is, at a slower than normal speech rate, more demands are placed on WM since information must be retained over a longer duration. the comprehension of normal and slow speech was examined for three Alzheimer's subjects, each presenting a unique profile of WM capacity. Results suggest that the effect of speech rate on comprehension is determined by the extent of WM capacity: A slow speech rate was beneficial only for the subject with the most preserved WM; speech rate did not affect ...
