阅读的神经生物学基础令人相当感兴趣，但在功能磁共振数据收集过程中，分析朗读单词的受试者的数据可能会很困难。因此，许多研究人员使用视觉匹配或押韵匹配等替代任务来消除对口语输出的需求。这些任务的使用已经被认为是正当的，因为当阅读时，与阅读相关的神经处理被假定为“自动激活”。我们通过直接比较进行视觉匹配任务和项目命名任务的受试者在单词、假词(无意义但合法的字母组合)和非单词(无意义和非法的字母组合)上的大胆活动，测试了使用非阅读任务来研究阅读效果的有效性。当直接比较时，在命名任务中，在“阅读相关”区域，如额叶下回和缘上回，有明显更多的活动。更重要的是，词汇性在任务中的作用是不同的。通过大胆的时间序列分析，通过大胆的时间序列分析，根据字符串类型(单词与假词与非单词)的全脑任务(匹配与命名)确定了显示这种三向交互作用的区域，包括左侧IFG和左侧角回(AG)。在大多数被识别的区域(包括左侧IFG和左侧AG)，命名中存在按时间顺序交互的字符串类型，但匹配任务中没有。这些结果表明，在特定区域进行的加工取决于任务，即使在与阅读相关的区域也是如此，因此是非自动的。当设计旨在调查阅读的研究时，这种差异应该被考虑在内。
The neurobiological basis of reading is of considerable interest, yet analyzing data from subjects reading words aloud during functional MRI data collection can be difficult. Therefore, many investigators use surrogate tasks such as visual matching or rhyme matching to eliminate the need for spoken output. Use of these tasks has been justified by the presumption of “automatic activation” of reading-related neural processing when a word is viewed. We have tested the efficacy of using a non-reading task for studying “reading effects” by directly comparing BOLD activity in subjects performing a visual matching task and an item naming task on words, pseudowords (meaningless but legal letter combinations), and nonwords (meaningless and illegal letter combinations). When compared directly, there is significantly more activity during the naming task in “reading-related” regions such as the inferior frontal gyrus (IFG) and supramarginal gyrus. More importantly, there are differing effects of lexicality in the tasks. A whole-brain task (matching vs naming) by string type (word vs pseudoword vs nonword) by BOLD timecourse analysis identifies regions showing this three-way interaction, including the left IFG and left angular gyrus (AG). In the majority of the identified regions (including the left IFG and left AG), there is a string type by timecourse interaction in the naming but not the matching task. These results argue that the processing performed in specific regions is contingent on task, even in reading-related regions, and is thus non-automatic. Such differences should be taken into consideration when designing studies intended to investigate reading.
