Lexical activation is a core process in models of spoken word recognition. Specific words activated are candidates, with degree of activation determined by the match with sensory information. Once identified, lexical activation shifts to provide a meaningful representation, normally through activation of semantically related words. Activated words are assumed to acquire familiarity as a result of being activated, providing a basis for memories, both real and imagined. Three experiments showed a direct relationship between number of false recognitions and their presumed degree of activation. Results converge with those from spoken word recognition in implicating lexical activation during early stages of processing. For recognition memory, the message is that prerecognition lexical processing should be included in the memory equation.
词汇激活是口语单词识别模型中的核心过程。被激活的特定单词成为候选词,其激活程度由与感官信息的匹配度决定。一旦被识别,词汇激活通常会通过激活语义相关的单词来转向提供有意义的表征。被激活的单词被认为由于被激活而获得熟悉度,为真实和想象的记忆提供基础。三项实验表明错误识别的数量与其假定的激活程度之间存在直接关系。结果与口语单词识别的结果一致,表明在处理的早期阶段存在词汇激活。对于识别记忆而言,这意味着在记忆等式中应纳入识别前的词汇处理。
