在上下文线索(CC)中,发现目标的反应时间在重复显示中比在从未见过的显示中更快。这已被证明使用目标干扰配置,全球背景颜色,自然的场景,和目标与干扰的协变。大多数CC研究都使用了目标始终存在的显示器。这项研究调查了当目标有时缺席时会发生什么。实验1表明,尽管当目标总是存在时,在显示器中出现了连续CC,但是当目标总是不存在时,没有CC。实验2表明,当同一空间布局在不同的实验中既有目标存在又有目标不存在时,不存在协同效应。在其他试验中包含目标的位置中存在干扰物似乎会干扰CC,甚至会破坏先前学习的上下文中CC的表达(Exps.第3-5段)。这些结果表明,目标干扰关联的重要因素,在产生CC和响应选择帐户,一致的,改变响应类型从定向任务到检测任务删除CC效应。
In contextual cuing (CC), reaction times for finding targets are faster in repeated displays than in displays that have never been seen before. This has been demonstrated using target–distractor configurations, global background colors, naturalistic scenes, and covariation of targets with distractors. The majority of CC studies have used displays in which the target is always present. This study investigated what happens when the target is sometimes absent. Experiment 1 showed that, although configural CC occurs in displays when the target is always present, there is no CC when the target is always absent. Experiment 2 showed that there is no CC when the same spatial layout can be both target present and target absent on different trials. The presence of distractors in locations that had contained targets on other trials appeared to interfere with CC, and even disrupted the expression of CC in previously learned contexts (Exps. 3–5). These results show that target–distractor associations are the important element in producing CC and that, consistent with a response selection account, changing the response type from an orientation task to a detection task removes the CC effect.
