采用相同-不同字母匹配任务来检验刺激强度对负启动的影响，当目标字母在前一试验中作为干扰字母呈现时，负启动的表现较差。在实验1中，刺激强度在被试之间被操纵，而在实验2中，刺激强度在被试内部随机变化。在实验1中，两种刺激强度的负启动是相等的。在实验2中，当刺激强度较弱时，重复强度刺激的负启动效应大于非重复强度刺激。对于重复强度刺激，当刺激所需的显性反应从启动重复到探测重复时，负启动效应增强。这些结果与负启动可能是由于记忆混乱的假设相一致，而不是由于干扰刺激的抑制。
A same-different letter-matching task was used to examine the effects of stimulus intensity on negative priming, which is poorer performance when target letters have been presented as distractor letters on the immediately preceding trial. In Experiment 1, stimulus intensity was manipulated between-participants, whereas in Experiment 2, it varied randomly from trial-to-trial within-participants. In Experiment 1, negative priming was equivalent for both stimulus intensities. In Experiment 2, negative priming effects were larger for repeated intensity stimuli than for nonrepeated intensity stimuli, when stimulus intensity was dim. Furthermore, for repeated intensity stimuli, negative priming effects were enhanced when the overt response required to the stimulus was repeated from prime to probe trial. These results are consistent with the hypothesis that negative priming may be due to memory confusion, rather than to inhibition of the distractor stimuli.
