词频是一个重要的心理语言变量，它解释了语言处理过程中的巨大差异。许多神经成像研究已经检查了单个单词水平的频率，典型地表明频率与血流动力学反应之间存在强烈的负相关，有时甚至是正相关。在这里，40名受试者在核磁共振扫描仪中阅读文本段落，同时记录他们的眼球运动。我们使用与注视相关的分析来识别与每个注视单词的频率相关的神经活动。我们发现，与频率的负相关减弱，而在与语义相关的颞区和顶区发现强烈的正相关。我们认为，由于上下文线索的存在，低频词的处理成本降低了。高频词的含义更容易被访问并与上下文集成，从而增强了语义系统中的处理。实验结果显示了单词加工与自然文本加工的异同。
Word frequency is a central psycholinguistic variable that accounts for substantial variance in language processing. A number of neuroimaging studies have examined frequency at a single word level, typically demonstrating a strong negative, and sometimes positive correlation between frequency and hemodynamic response. Here, 40 subjects read passages of text in an MRI scanner while their eye movements were recorded. We used fixation-related analysis to identify neural activity tied to the frequency of each fixated word. We found that negative correlations with frequency were reduced, while strong positive correlations were found in the temporal and parietal areas associated with semantics. We propose that the processing cost of low frequency words is reduced due to contextual cues. Meanings of high frequency words are more readily accessed and integrated with context resulting in enhanced processing in the semantic system. The results demonstrate similarities and differences between single word and naturalistic text processing.
