Language is the most evolved and complex of cognitive functions. During recent years, its study has largely benefited from new medical imaging technologies among which positron emission tomography (PET), allowing for direct observation of in vivo human brain activity. This paper reviews some of the important advances in the understanding of single-word processing provided by PET, integrating them in the context of other fields of investigation such as cognitive neuropsychology. It also points out the limitations of the technique and some of its recent developments, opening the way for further comprehension of language processing.
语言是认知功能中最发达、最复杂的。近年来,对语言的研究在很大程度上受益于新的医学成像技术,其中正电子发射断层扫描(PET)能够直接观察活体人类大脑活动。本文回顾了PET在单字加工理解方面取得的一些重要进展,并将其置于认知神经心理学等其他研究领域的背景下进行整合。文章还指出了该技术的局限性及其近期的一些发展,为进一步理解语言加工开辟了道路。
