Abstract

The contextual cueing effect-where participants search repeated displays faster than novel ones-is often explained by the "attention guidance" account, which posits that repeated exposure helps individuals learn the context and attend to the likely target locations. Alternatively, the "generic procedural learning" account suggests that a general search strategy is developed for all displays, although repeated contexts play a higher weight in optimizing the strategy due to their higher presented frequency. This makes responses faster for repeated displays than novel displays. The current study examined these two mechanisms using a varied contextual cueing paradigm to analyze response time (RT) variability with the coefficient of variation (CV) and time-frequency analysis of RTs. Experiment 1 involved uninterrupted training with repeated and novel displays presented separately, followed by a test with randomly interleaved repeated and novel displays. Experiment 2 used interleaved displays for training before an uninterrupted test phase. Both experiments revealed faster RTs and reduced template-based variability for repeated displays early in the training, supporting attentional guidance. However, generic procedural learning, indicated by a late onset of lower cross-display variability for repeated displays, required more time and training to validate the cueing effect. These findings suggest that attentional guidance dominates early learning, but both mechanisms contribute to the contextual cueing effect overall.

基于模板的注意力引导和上下文引导视觉搜索中的一般程序学习:来自减少反应时间变异性的证据。
情境线索效应——参与者搜索重复展示的速度比搜索新展示的速度要快——通常用“注意力引导”的说法来解释,该说法认为,反复接触有助于个人了解情境,并注意到可能的目标位置。另外,“通用程序学习”的解释表明,一个通用的搜索策略是为所有显示开发的,尽管重复上下文在优化策略中发挥更大的权重,因为它们的出现频率更高。这使得对重复显示的反应比对新显示的反应更快。本研究使用不同的情境线索范式来分析反应时间(RT)的变异系数(CV)和时频分析,以检验这两种机制。实验1是不间断的训练,重复和新奇的展示分别呈现,然后是随机交错的重复和新奇的展示。实验2在不间断测试阶段之前使用交错显示进行训练。两项实验都显示,在训练早期,重复显示的快速反应和基于模板的变异性减少,支持注意力指导。然而,一般的程序性学习,表现为延迟出现的低交叉显示变异性,需要更多的时间和训练来验证提示效果。这些发现表明,注意指导主导着早期学习,但这两种机制都有助于整体的情境线索效应。
