负启动效应(NP)被评估为在主目标加工中知觉负荷的函数，来自无关干扰物。参与者在显示器中央的不同数量的非目标字母中搜索目标字母，而忽略了无关的外围干扰。来自该干扰项的NP被发现依赖于相关的搜索集合大小，并且随着该集合大小的增加而减少。作者得出的结论是，在相关加工中耗尽注意力会减少不相关的加工(例如，N.Lavie，1995)，从而减少产生NP的分心加工。这一结论与最近对NP的反应抑制观点是一致的(例如G.Houghton，S.P.Tipper，B.Weaver，&D.I，Shore，1996)。
Negative priming (NP) effects from irrelevant distractors were assessed as a function of perceptual load in the processing of prime targets. Participants searched for a target letter among a varying number of nontarget letters in the center of the display and ignored an irrelevant peripheral distractor. NP from this distractor was found to depend on the relevant search set size, decreasing as this set size was increased. The authors conclude that exhausting attention in relevant processing reduces irrelevant processing (e.g., N. Lavie, 1995), leaving less distractor processing to produce NP. This conclusion is consistent with recent reactive inhibition views for NP (e.g., G. Houghton, S. P. Tipper, B. Weaver, & D. I, Shore, 1996).
