A number of experiments have shown that the magnitude of the associative priming effect increases substantially when there is a high proportion of associatively related pairs in the list when the stimulus-onset asynchrony (SOA) between prime and target is long (more than 400 ms). In the present series of experiments we manipulated the proportion of associatively related pairs when the SOA was very brief (less than 200 ms). If processing of a target word is facilitated automatically by the prior presentation of a related prime, the occurrence of priming should be unaffected by the proportion of related pairs in the list. Experiment 1 showed a robust relatedness proportion effect obtained in a double lexical decision task. Experiments 2-4 used the masked priming technique at several very short SOAs (66, 116, and 166 ms) in lexical decision and naming. The results showed a reliable associative priming effect in the two tasks, which did not differ as a function of the proportion of related pairs. Finally, Experiment 5 used unmasked primes at an 83-ms SOA in which the primes remained in view after the target presentation. As in Experiments 2-4, the associative effect was not modulated by the proportion of associatively related pairs. The implications of these results are discussed.
多项实验表明，当启动刺激与目标刺激之间的刺激呈现间隔（SOA）较长（超过400毫秒）且列表中联想相关对的比例较高时，联想启动效应的幅度会大幅增加。在本系列实验中，我们在SOA非常短暂（小于200毫秒）的情况下操纵了联想相关对的比例。如果相关启动刺激的先前呈现能自动促进目标词的加工，那么启动效应的出现应该不受列表中相关对比例的影响。实验1在双重词汇判断任务中显示出了显著的相关性比例效应。实验2至4在词汇判断和命名任务中，于几个非常短的SOA（66、116和166毫秒）下使用了掩蔽启动技术。结果在这两个任务中均显示出了可靠的联想启动效应，且该效应并未因相关对的比例而有所不同。最后，实验5在83毫秒的SOA下使用了非掩蔽启动刺激，其中启动刺激在目标呈现后仍可见。与实验2至4一样，联想效应并未受到联想相关对比例的调节。我们对这些结果的意义进行了讨论。
