使用波斯纳空间线索范式的研究表明，参与者可以根据先前线索的预测性将注意力分配到特定的目标位置。四个实验进行了调查注意定向过程中操作的高概率条件（线索75%的预测）相比，使用各种类型的中央呈现的线索的低概率条件（线索50%的预测）。空间信息的线索（箭头和圆圈的差距），导致提示效果（CE）的概率条件下，显着更大的CE在高概率条件下比低概率条件。在高概率条件下的参与者报告说，很少或根本没有意识到任务完成后的线索-目标概率。我们的研究结果提供了支持的实验条件下，涉及空间信息的中央线索和相对较短的刺激起始时间（SOA）的内隐学习帐户的比例有效的效果。(C)2011 Elsevier Inc.

Studies using Posner's spatial cueing paradigm have demonstrated that participants can allocate their attention to specific target locations based on the predictiveness of preceding cues. Four experiments were conducted to investigate attentional orienting processes operating in a high probability condition (cues 75% predictive) as compared to a low probability condition (cues 50% predictive) using various types of centrally-presented cues. Spatially-informative cues (arrows and circles with gaps) resulted in cueing effects (CEs) for both probability conditions, with significantly larger CEs in the high probability conditions than the low probability conditions. Participants in the high probability conditions reported little or no awareness of cue-target probabilities after task completion. Our results provide support for an implicit learning account of the proportion valid effect under experimental conditions involving spatially-informative central cues and relatively short stimulus onset asynchronies (SOAs).
