两个词汇决定实验比较了掩蔽词的语义启动和重复启动。实验1建立了具有在场-不在场检测判断的启动掩蔽刺激起始模型。启动检测阈值SOA产生相同的促进重复和语义相关的目标：26毫秒和24毫秒。实验2建立SOA与语义判断。以70%的语义阈值SOA呈现的启动模拟实验1的暴露条件，对重复目标产生略大的易化，但对语义相关目标产生抑制的趋势：38 ms和− 6 ms。这些结果证实了Dagenbach，卡尔和Wilhelmsen（1989）的报告，即阈值设置任务诱导的策略可以影响掩蔽启动。此外，实验2提出了一种机制，检索弱激活的语义代码进入意识，依赖于中心-环绕原则，以增强激活的搜索代码，并抑制存储在语义网络附近的相关代码。
Two lexical decision experiments compared semantic and repetition priming by masked words. Experiment 1 established prime–mask stimulus onset asynchronies (SOAs) with presence–absence detection judgments. Primes presented at detection-threshold SOAs produced equal facilitation for repeated and semantically related targets: 26 ms and 24 ms. Experiment 2 established SOAs with semantic judgments. Primes presented at 70% of the semantic-threshold SOA to mimic the exposure conditions of Experiment 1 produced slightly greater facilitation for repeated targets but a tendency toward inhibition for semantically related targets: 38 ms and− 6 ms. These results confirm Dagenbach, Carr, and Wilhelmsen's (1989) report that strategies induced by threshold-setting tasks can influence masked priming. In addition, Experiment 2 suggests a mechanism for retrieving weakly activated semantic codes into consciousness that relies on the center-surround principle to enhance activation of sought-for codes and to inhibit related codes stored nearby in the semantic network.
