The size and font of target words were manipulated in a masked repetition priming paradigm with ERP recordings. Repetition priming effects were found in four ERP components: the N/P150, N250, P325, and N400. Neither a change in font nor a change in size across prime and target were found to affect repetition priming in the N250, P325, and N400 components. Changing font was, however, found to affect repetition priming in the N/P150 component, while the interaction between repetition priming and size was not significant in this component. These results confirm our interpretation of the N/P150 as a component sensitive to feature-level processing, and suggest that the type of prelexical and lexical processing reflected in the N250, P325, and N400 components is performed on representations that are invariant to changes in both font and size.
在一项带有事件相关电位(ERP)记录的掩蔽重复启动范式中,对目标词的大小和字体进行了操控。在四个ERP成分中发现了重复启动效应:N/P150、N250、P325和N400。在N250、P325和N400成分中,启动刺激和目标刺激之间的字体变化或大小变化均未被发现会影响重复启动。然而,改变字体被发现会影响N/P150成分中的重复启动,而在该成分中重复启动与大小之间的交互作用并不显著。这些结果证实了我们将N/P150解释为对特征水平加工敏感的成分,并表明N250、P325和N400成分中所反映的词前和词汇加工类型是在对字体和大小变化均不变的表征上进行的。
