Masked priming has long been used to demonstrate the impact of brief presentations of orthographically related stimuli on visual word recognition. The aim of the present study was to examine neural correlates of orthographic priming produced by pronounceable and unpronounceable anagram primes. Crucially, we examined relationships between these priming effects and individual differences on a battery of measures assessing orthographic processing ability, current reading ability, and verbal intelligence in university students. Our study demonstrated group-level priming effects on the N200 and N400, with both components being primarily modulated by unpronounceable, orthographically illegal primes. Relationships between the extent of priming as indexed by N200 amplitude and speed of orthographic processing emerged, as reaction time (RT) on an orthographic choice task was associated with priming effects. Priming effects on N400 amplitude were related to phonological decoding efficiency. Those individuals with less efficient orthographic or phonological processing were more sensitive to the orthographic relationship between primes and targets. These findings demonstrate that university students vary in their sensitivity to orthographic priming and the degree to which orthographic information is used during word recognition.

ERPs揭示了神经正字法启动效果与阅读技巧之间的关系

长期以来，遮罩式底漆已被用来证明拼字法相关刺激的简短介绍对视觉单词识别的影响。本研究的目的是检查由明显和不可发音的字谜素数产生的正字法引发的神经相关性。至关重要的是，我们通过一系列评估学生的正字处理能力，当前阅读能力和口头智力的措施，研究了这些启动效应与个体差异之间的关系。我们的研究证明了对N200和N400的组级启动作用，这两个分量主要受不可发音的，正交的非法启动量调节。出现了以N200振幅为索引的灌注程度与正交处理速度之间的关系，正字法选择任务的反应时间（RT）与启动效果相关。N400振幅的启动效应与语音解码效率有关。正交或语音处理效率较低的个人对素数和目标之间的正交关系更为敏感。这些发现表明，大学生对正字法启动的敏感性和单词识别过程中使用正字法信息的程度各不相同。
