Few studies have focused on language processing across modalities. Two experiments examined between-modality interactions across three prime-target intervals (0, 200, and 800 ms) in a cross-modal repetition priming paradigm. Event-related potentials were recorded to auditory targets following visual primes (Experiment 1) or visual targets following auditory primes (Experiment 2). In Experiment 1 robust repetition effects were found for auditory targets as early as 100 ms, and continued through the N400 epoch. Moreover, these visual-auditory repetition effects were large across all three prime-target intervals although they onset 200 ms later at the shortest interval. In Experiment 2 repetition effects to visual targets started later (at 200 ms), but also offset relatively later (approximately 1000 ms). These auditory-visual repetition effects were both smaller overall and absent for the two shortest prime-target intervals during the typical N400 window.
很少有研究关注跨模态的语言处理。两项实验在跨模态重复启动范式中，考察了三个启动-目标间隔（0、200和800毫秒）下的跨模态交互作用。在视觉启动后呈现听觉目标（实验1）或听觉启动后呈现视觉目标（实验2）时，记录事件相关电位。在实验1中，早在100毫秒时就发现了对听觉目标的强烈重复效应，并持续到N400时段。此外，尽管在最短间隔时延迟200毫秒出现，但在所有三个启动-目标间隔中，这些视觉-听觉重复效应都很大。在实验2中，对视觉目标的重复效应开始较晚（200毫秒），但结束也相对较晚（约1000毫秒）。在典型的N400窗口期间，这些听觉-视觉重复效应总体上较小，并且在两个最短的启动-目标间隔中不存在。
