Word pairs may be integrative (i.e., combination of two concepts into one meaningful entity; e.g., fruit-cake), thematically related (i.e., connected in time and place; e.g., party-cake), and/or taxonomically related (i.e., shared features and category co-members; e.g., muffin-cake). Using participant ratings and computational measures, we demonstrated distinct patterns across measures of similarity and co-occurrence, and familiarity for each relational construct in two different item sets. In a standard lexical decision task (LDT) with various delays between prime and target presentation (SOAs), target RTs and priming magnitudes were consistent across the three relations for both item sets. However, across the SOAs, there were distinct patterns among the three relations on some of the underlying measures influencing target word recognition (LSA, Google, and BEAGLE). These distinct patterns suggest different mechanisms of lexical priming and further demonstrate that integrative relations are distinct from thematic and taxonomic relations.
词对可能是整合性的（即，将两个概念组合成一个有意义的实体；例如，水果蛋糕）、主题相关的（即，在时间和地点上有联系；例如，派对-蛋糕），和/或分类相关的（即，具有共同特征且属于同一类别；例如，松饼-蛋糕）。通过参与者评分和计算方法，我们在两个不同的项目集中展示了每种关系结构在相似性、共现性和熟悉度测量方面的不同模式。在一个标准的词汇判断任务（LDT）中，启动刺激和目标呈现之间存在各种延迟（刺激呈现间隔），两个项目集在三种关系下的目标反应时间和启动效应大小都是一致的。然而，在整个刺激呈现间隔中，在一些影响目标词识别的潜在测量指标（潜在语义分析、谷歌和比格犬）上，三种关系之间存在不同的模式。这些不同的模式表明了词汇启动的不同机制，并进一步证明了整合关系与主题关系和分类关系是不同的。
