扩散激活理论和复合线索理论都被提出作为启动现象的解释。根据扩散激活理论，在启动和目标之间传播的激活量应该是语义网络中启动和目标之间的中介链接数量和这些链接强度的函数。在词汇决策中，激活量应该决定启动对目标的促进量。为了预测易化程度，有必要测量记忆中启动和目标之间的联想联系。在以往的研究中，自由关联生产概率一直是这个测量选择的变量。然而，在3个实验中，作者展示了启动效应，这是自由联想产生概率无法轻易预测的。相反，他们认为启动的数量取决于启动和目标作为一个化合物的熟悉程度，其中化合物是由启动和目标作为一个测试项目同时出现在短期记忆中形成的。
Spreading activation theories and compound cue theories have both been proposed as accounts of priming phenomena. According to spreading activation theories, the amount of activation that spreads between a prime and a target should be a function of the number of mediating links between the prime and target in a semantic network and the strengths of those links. The amount of activation should determine the amount of facilitation given by a prime to a target in lexical decision. To predict the amount of facilitation, it is necessary to measure the associative links between prime and target in memory. Free-association production probability has been the variable chosen in previous research for this measurement. However, in 3 experiments, the authors show priming effects that free-association production probabilities cannot easily predict. Instead, they argue that amount of priming depends on the familiarity of the prime and target as a compound, where the compound is formed by the simultaneous presence of the prime and target in short-term memory as a test item.
