两个实验研究了跨试验位置启动（V. Maljkovic & K。Nakayama，1994，1996，2000）在视觉弹出搜索中。实验我使用定期安排的目标和干扰显示，在以前的研究。当目标出现在先前的目标位置时，反应时间加快（相对于中性基线的易化），当目标出现在先前的干扰物位置时，反应时间减慢（抑制）。与易化相反，抑制只有在长期练习后才出现。实验2揭示了减少促进和抑制启动时，元素的空间排列是不规则的，这表明位置，特别是记忆启动关键取决于整个序列的审判的显示元素的配置。这些结果进行了讨论，相对于视觉弹出搜索中的跨试验启动的背景下的作用。
Two experiments examined cross-trial positional priming (V. Maljkovic & K. Nakayama, 1994, 1996, 2000) in visual pop-out search. Experiment I used regularly arranged target and distractor displays, as in previous studies. Reaction times were expedited when the target appeared at a previous target location (facilitation relative to neutral baseline) and slowed when the target appeared at a previous distractor location (inhibition). In contrast to facilitation, inhibition emerged only after extended practice. Experiment 2 revealed reduced facilitatory and no inhibitory priming when the elements' spatial arrangement was made irregular, indicating that positional-in particular, inhibitory-priming critically depends on the configuration of the display elements across sequences of trials. These results are discussed with respect to the role of the context for cross-trial priming in visual pop-out search.
