检查了选择性处理的语义和空间影响。在 1/3 的试验中，在一对屏蔽词与其中 1 个词相关之前，素数出现 250 毫秒或 1,000 毫秒。尽管实验 1 和 2 都需要报告两个单词，但处理是有选择性的；通常，只能报告 1 个单词。在实验 1 中，报告的单词通常是最上面的单词，显示出空间选择性，并且更常见的是与素数相关的单词，显示出语义选择性。实验 2 包括在这对之前 50 毫秒被忽略的外围线索。在这两种延迟下，相关词的报告频率更高，并且提示在 1,000 毫秒时产生了额外的好处。实验 3 只需要报告提示词并包括 100 毫秒的提示。提示词的报告频率更高，特别是在 1,000 毫秒和 100 毫秒提示时，但也出现了语义选择性。通过语义启动和通过位置的选择性反映了不同的注意机制。
Semantic and spatial effects on selective processing were examined. A prime presented 250 ms or 1,000 ms before a pair of masked words was related to 1 of the words on 1/3 of the trials. Although Experiments 1 and 2 required report of both words, processing was selective; typically, just 1 word could be reported. In Experiment 1, reported words were more often top words, showing spatial selectivity, and more often words related to the prime, showing semantic selectivity. Experiment 2 included to-be-ignored peripheral cues 50 ms before the pair. Related words were reported more often at both delays, and cuing produced an additive benefit at 1,000 ms. Experiment 3 required report of just the cued word and included 100-ms cues. Cued words were reported more often, especially at 1,000 ms and with 100-ms cues, but semantic selectivity also occurred. Selectivity via semantic priming and via location reflect separate attentional mechanisms.
