四个实验研究了元对比掩蔽素数对时序判断的影响。主要结果是：（1）掩蔽启动减少了掩蔽的有意识知觉的潜伏期（知觉潜伏期启动），（2）这一效应与启动是否遭受强掩蔽或弱掩蔽无关，（3）它不受启动和掩蔽之间的视觉相似程度的影响，（4）一致启动和不一致启动之间没有差异。结果（1）表明，位置提示不仅影响反应时间，而且影响有意识知觉的潜伏期。(2)这一发现，启动是不受总理的可检测性反对这种效果的反应偏见解释。(3)由于视觉相似性对启动效率没有影响，因此不太可能涉及感觉启动。(4)一致和不一致启动的效果之间缺乏分歧意味着时序判断任务中的判断与已经证明一致和不一致启动的差异效果的快速反应之间存在功能差异（例如，Klotz和Neumann，1999年）。这些结果可以通过假设启动通过启动注意转移来影响感知延迟来最好地解释，正如异步更新模型（AUM; Neumann 1978，1982）所建议的那样。
Four experiments investigated the influence of a metacontrast-masked prime on temporal order judgments. The main results were (1) that a masked prime reduced the latency of the mask's conscious perception (perceptual latency priming), (2) that this effect was independent of whether the prime suffered strong or weak masking, (3) that it was unaffected by the degree of visual similarity between the prime and the mask, and that (4) there was no difference between congruent and incongruent primes. Finding (1) suggests that location cueing affects not only response times but also the latency of conscious perception. (2) The finding that priming was unaffected by the prime's detectability argues against a response bias interpretation of this effect. (3) Since visual similarity had no effect on the prime's efficiency, it is unlikely that sensory priming was involved. (4) The lack of a divergence between the effects of congruent and incongruent primes implies a functional difference between the judgments in the temporal order judgment task and speeded responses that have demonstrated differential effects of congruent and incongruent primes (e.g., Klotz & Neumann, 1999). These results can best be interpreted by assuming that the prime affects perceptual latency by initiating a shift of attention, as suggested by the Asynchronous Updating Model (AUM; Neumann 1978, 1982).
