本研究考察了词汇、句法和语义信息水平对句子启动在左半球和右半球的贡献。受试者做出词汇决定，在目标词之前横向呈现一致的、不一致的、句法的、随机的和中性的不完整句子，这些句子要么包含或不包含目标词的词汇联想。在左联测验中，同义联想句被促进，不一致联想句被抑制，目标词被广泛识别。在RH也发现了类似的模式，但减弱了。在左、右两组中，随机联想句对词目标识别的促进作用都非常温和。句法关联句素数包含嵌入在无意义消息中的词级信息，提供了RH受益而LH不受益的条件。LH区和RH区句子类型语境效应的不对称性表明，两个半球可利用的信息水平过程存在一些重要的差异。(C)2002爱思唯尔科学有限公司。保留所有权利。
The present study examined lexical, syntactic and semantic message-level contributions to sentence priming in the left (LH) and right (RH) hemispheres. Participants made lexical decisions to laterally presented target words preceded by congruent, incongruent, syntactic, random and neutral incomplete sentences that either contained or did not contain a lexical associate of the target. In the LH, congruent associated sentences facilitated, and incongruent associated sentences inhibited, target word recognition extensively. A similar pattern, but attenuated, was found for the RH. In both the LH and RH, random associated sentences benefited word target recognition very moderately. Syntactic associated sentence primes that contain word-level information embedded in a meaningless message provided the condition in which the RH was benefited but the LH was not. The asymmetry of sentence type context effects in the LH and RH suggests some important differences in message-level processes available to each hemisphere. (C) 2002 Elsevier Science Ltd.
