問題詳情

四、閱讀測驗【請在下列各題中選出最適當的答案】People who speak more than one language and who develop dementia tend to do so up to five years later thanthose who are monolingual, according to a study.Scientists examined almost 650 dementia patients and assessed when each one had been diagnosed with thecondition. They found people who spoke two or more languages experienced a later onset of Alzheimer’s disease,vascular dementia and frontotemporal dementia. The bilingual advantage extended to illiterate people. The scientistssaid it confirmed the observed effect was not caused by differences in formal education. The study was conductedby Edinburgh University and Nizam’s Institute of Medical Sciences in Hyderabad in India.It is the largest study so far to gauge the impact of bilingualism on the onset of dementia, independent of aperson’s education, gender, occupation and whether they live in a city or in the country, all of which have beenexamined as potential factors influencing the onset of dementia.The team of researchers said further studies were needed to determine the mechanism which causes the delay inthe onset of dementia. The researchers suggested bilingual switching between different sounds, words, concepts,grammatical structures and social norms constituted a form of natural brain training, which was likely to be moreeffective than any artificial brain training program.However, studies of bilingualism are complicated in that bilingual populations are often ethnically andculturally different from monolingual societies. In places like Hyderabad, bilingualism is part of everyday life,knowledge of several languages is the norm and monolingualism is an exception.Thomas Bak, of Edinburgh University’s school of philosophy, psychology and language sciences said: “Thesefindings suggest that bilingualism might have a stronger influence on dementia than any currently available drugs.This makes the study of the relationship between bilingualism and cognition one of our highest priorities.”
