It is generally assumed that the correlational cuing effect (CE) between targets and correlated flankers is due to learning association between the flankers and their correlated responses. The present study challenges this view. Experiment 1 shows that the CE for targets composed of color is eliminated as soon as the correlation is removed. Experiment 2 shows that the CE during training is not due to association of the flankers with responses. Experiment 3 shows that at least some of the CE during training with the correlation is due to repetition priming of the display. Experiment 4 replicates the results of Experiment 1 for orientation targets. In Experiments 5-7, more typical tasks with letter targets are examined, and it is demonstrated that preexperimental similarity between targets and correlated flankers is crucial. The CE for correlated but dissimilar target-flanker pairs, similar to that for color and orientation targets, is confined to on-line processes that occur during training. The CE is transferred, however, for correlated and similar target-flanker pairs. We propose that, at least for the simple stimulus to response mapping used in our study, the CE is not due to learning at all. Instead it is due to (1) on-line processes, such as repetition priming, that occur during training with the correlation and (2) a regular flanker effect (see, e.g., B. A. Eriksen & C. W. Eriksen, 1974) that occurs for similar target-flanker pairs.
一般认为,目标与相关侧翼刺激之间的关联提示效应(CE)是由于侧翼刺激与其相关反应之间的学习关联所致。本研究对这一观点提出了挑战。实验1表明,一旦相关性被消除,由颜色组成的目标的CE就会消失。实验2表明,训练期间的CE并非由于侧翼刺激与反应的关联。实验3表明,训练期间与相关性相关的至少部分CE是由于显示的重复启动。实验4重复了实验1中关于方向目标的结果。在实验5 - 7中,对更典型的字母目标任务进行了研究,并证明目标与相关侧翼刺激之间的实验前相似性至关重要。与颜色和方向目标类似,相关但不相似的目标 - 侧翼刺激对的CE仅限于训练期间发生的在线过程。然而,对于相关且相似的目标 - 侧翼刺激对,CE会发生转移。我们提出,至少对于我们研究中使用的简单刺激到反应的映射,CE根本不是由于学习。相反,它是由于(1)在与相关性相关的训练期间发生的在线过程,如重复启动,以及(2)对于相似的目标 - 侧翼刺激对发生的常规侧翼效应(例如,见B. A. 埃里克森和C. W. 埃里克森,1974)。
