摘要

词频效应一直是阅读研究的兴趣所在,因为它在探索阅读行为背后的心理加工过程中起着至关重要的作用。词频信息的获取一直被认为是词汇加工开始的指标,也是研究大脑何时开始提取语义信息的最敏感标记 Sereno & Rayner, Brain and Cognition, 42, 78-81, (2000), Trends in Cognitive Sciences, 7, 489-493, (2003)。虽然词频效应已在大量眼动跟踪和使用 RSVP 范式的传统脑电图研究中得到广泛研究,但在自然阅读研究中却缺乏相应的证据。为了找到词频效应的神经相关因素,我们利用脑电图和眼动追踪核心定位技术对中文自然阅读进行了研究,以考察词汇加工的时间过程。我们的结果可靠地表明,词频效应首先出现在 N200 时间窗和双侧枕颞区。此外,词频效应还反映在 N400 时间窗中,并从枕叶区扩散到中央顶叶区和额叶区。我们目前的研究首次提供了汉语自然阅读中词频效应的神经相关性,为理解自然阅读中的词汇加工提供了新的启示,并可作为进一步阅读研究中考虑神经相关性的重要依据。

Neural correlates for word-frequency effect in Chinese natural reading.

Neural correlates for word-frequency effect in Chinese natural reading.

Word frequency effect has always been of interest for reading research because of its critical role in exploring mental processing underlying reading behaviors. Access to word frequency information has long been considered an indicator of the beginning of lexical processing and the most sensitive marker for studying when the brain begins to extract semantic information Sereno & Rayner, Brain and Cognition, 42, 78-81, (2000), Trends in Cognitive Sciences, 7, 489-493, (2003). While the word frequency effect has been extensively studied in numerous eye-tracking and traditional EEG research using the RSVP paradigm, there is a lack of corresponding evidence in studies of natural reading. To find the neural correlates of the word frequency effect, we conducted a study of Chinese natural reading using EEG and eye-tracking coregistration to examine the time course of lexical processing. Our results reliably showed that the word frequency effect first appeared in the N200 time window and the bilateral occipitotemporal regions. Additionally, the word frequency effect was reflected in the N400 time window, spreading from the occipital region to the central parietal and frontal regions. Our current study provides the first neural correlates for word-frequency effect in natural Chinese reading so far, shedding new light on understanding lexical processing in natural reading and could serve as an important basis for further reading study when considering neural correlates in a realistic manner.

期刊介绍: The journal Attention, Perception, & Psychophysics is an official journal of the Psychonomic Society. It spans all areas of research in sensory processes, perception, attention, and psychophysics. Most articles published are reports of experimental work; the journal also presents theoretical, integrative, and evaluative reviews. Commentary on issues of importance to researchers appears in a special section of the journal. Founded in 1966 as Perception & Psychophysics, the journal assumed its present name in 2009.
