Three experiments are reported on lexical decision to target stimuli presented to the right or left visual field (RVF, LVF) following a variety of priming stimuli, words, incomplete sentences, and scrambled sentences. Lexical decision performance is always superior for stimuli presented to the RVF. Primes always facilitate the discrimination of words from nonword target stimuli presented to either visual field. However, when the prime is a sentence which is completed syntactically and semantically by a target word (normal, congruent sentence), the facilitation for RVF presented targets is significantly greater than for LVF targets. When the prime is either: (1) a single word, (2) a nonstructured (scrambled) sentence, or (3) a noncongruent-related sentence, the difference in facilitation between RVF and LVF presented targets is much smaller. These data are discussed with respect to (1) the nature of priming by sentences versus words, (2) language processing by the two hemispheres, and (3) modularity versus interactionism in language processing.
本文报告了三项实验，这些实验针对在呈现各种启动刺激（单词、不完整句子和打乱句子）之后呈现给右视野或左视野（RVF，LVF）的目标刺激进行词汇判断。对于呈现给右视野的刺激，词汇判断表现总是更优。启动刺激总是有助于区分呈现给任一视野的单词与非单词目标刺激。然而，当启动刺激是一个由目标单词在句法和语义上完成的句子（正常、一致的句子）时，对呈现给右视野的目标的促进作用明显大于对呈现给左视野的目标的促进作用。当启动刺激是以下情况之一时：（1）单个单词，（2）非结构化（打乱）句子，或（3）不一致相关句子，呈现给右视野和左视野的目标在促进作用上的差异要小得多。本文从以下几个方面讨论了这些数据：（1）句子与单词启动的性质，（2）两个半球的语言处理，以及（3）语言处理中的模块性与交互作用。
