D.E.Huber、R.M.Shiffrin、K.B.Lyle和K.I.Ruys(2001)在一项短期启动任务中测试了两种选择、强迫选择(2-AFC)的知觉识别。用于重复启动。被动观看启动字导致选择重复单词的偏好，而对启动字的主动反应导致偏好选择重复单词。这些结果是用计算模型解释的，使用来源混淆和贴现的抵消机制，对未知证据来源(ROUSE)做出最佳反应。对Rouse的一项分析揭示了折扣效应应该减弱的条件，这导致了对启动词的偏好，即使在活跃的启动加工中也是如此。两项新的研究证实了两个这样的条件：目标闪光持续时间非常短，启动词和启动选择词之间的相似度非常低。这些先验预测与R.Ratcliff和G.McKoon(2001)开发的多项式模型的后验数据拟合形成了对比。
D. E. Huber, R. M. Shiffrin, K. B. Lyle, and K. I. Ruys (2001) tested two-alternative, forced-choice (2-AFC) perceptual identification in a short-term priming task. For repetition priming. passive viewing of primes resulted in a preference to choose repeated words, but actively responding to primes resulted in a preference against choosing repeated words. These results were explained with a computational model, responding optimally with unknown sources of evidence (ROUSE), using the offsetting mechanisms of source confusion and discounting. An analysis of ROUSE revealed conditions under which discounting efficacy should diminish, causing a preference for primed words even with active prime processing. Two new studies confirm 2 such conditions: very short target flash durations and very low similarity between primes and primed choice words. These a priori predictions contrast with the a posteriori data fits of a multinomial model developed by R. Ratcliff and G. McKoon (2001).
