In previous studies, additive effects of masked repetition and word frequency on lexical decision latency have been reported. This additive pattern was replicated in Experiment 1 with the use of low-frequency words (range, 1-7 per million) selected at random. In contrast, in Experiment 2, in which low-frequency words known to be familiar to the subjects were used, the masked repetition priming effect was greater for low-frequency than for high-frequency words. It is suggested that the absence of an interaction between masked repetition and frequency observed in previous studies and in the present Experiment 1 was due to the fact that very-low-frequency words often have an unstable representation in the subjects' lexicon and, consequently, sometimes fail to produce repetition priming effects in full.
在先前的研究中，已报道了掩蔽重复和词频对词汇判断潜伏期的累加效应。在实验1中，使用随机选择的低频词（范围为每百万个词中有1 - 7个）再现了这种累加模式。相比之下，在实验2中，使用了受试者已知熟悉的低频词，低频词的掩蔽重复启动效应比高频词更大。有人提出，先前研究和本实验1中观察到的掩蔽重复和频率之间缺乏交互作用，是因为极低频率的词在受试者的词汇表中往往具有不稳定的表征，因此有时无法充分产生重复启动效应。
