There has been conflicting evidence to date regarding the existence of non-strategic semantic priming based on semantic similarity, and in particular on visual-perceptual semantic features (e.g., button-coin: words refer to objects with the same global shape). Both event-related potential (ERP) and reaction time (RT) measures were employed to investigate visual-perceptual semantic priming in a word-pair lexical decision task designed to minimise the contribution of conscious strategic processing. While no RT priming effect was observed, a robust priming effect was obtained on the N400 component of the ERP. This result shows that semantic priming, as indexed by the N400 component, can be supported by nonassociative visual-perceptual semantic relations. The data are consistent with perceptual form information being accessed during the processing of concrete words, and provide support for models of semantic representation which incorporate semantic features and form information.
迄今为止，关于基于语义相似性，特别是视觉感知语义特征（例如，按钮 - 硬币：单词指代具有相同整体形状的物体）的非策略性语义启动的存在，存在相互矛盾的证据。在一项旨在最小化有意识策略加工贡献的词对词汇判断任务中，采用了事件相关电位（ERP）和反应时间（RT）测量来研究视觉感知语义启动。虽然未观察到反应时间启动效应，但在ERP的N400成分上获得了强烈的启动效应。这一结果表明，由N400成分索引的语义启动可以由非联想性视觉感知语义关系支持。数据与具体词汇加工过程中感知形式信息的获取一致，并为纳入语义特征和形式信息的语义表征模型提供了支持。
