Visual search is often facilitated when the search display occasionally repeats, revealing a contextual-cueing effect. According to the associative-learning account, contextual cueing arises from associating the display configuration with the target location. However, recent findings emphasizing the importance of local context near the target have given rise to the possibility that low-level repetition priming may account for the contextual-cueing effect. This study distinguishes associative learning from local repetition priming by testing whether search is directed toward a target's expected location, even when the target is relocated. After participants searched for a T among Ls in displays that repeated 24 times, they completed a transfer session where the target was relocated locally to a previously blank location (Experiment 1) or to an adjacent distractor location (Experiment 2). Results revealed that contextual cueing decreased as the target appeared farther away from its expected location, ultimately resulting in a contextual cost when the target swapped locations with a local distractor. We conclude that target predictability is a key factor in contextual cueing.
当搜索显示偶尔重复时,视觉搜索通常会变得更加容易,这显示出一种情境线索效应。根据联想学习理论,情境线索效应源于将显示配置与目标位置联系起来。然而,最近强调目标附近局部情境重要性的研究结果引发了一种可能性,即低水平的重复启动可能是情境线索效应的原因。本研究通过测试即使目标重新定位,搜索是否仍指向目标的预期位置,来区分联想学习和局部重复启动。在参与者在重复24次的显示中搜索L中的T之后,他们完成了一个转移阶段,其中目标被局部重新定位到先前的空白位置(实验1)或相邻的干扰位置(实验2)。结果显示,随着目标出现在离其预期位置更远的地方,情境线索效应会降低,最终当目标与局部干扰项交换位置时会产生情境成本。我们得出结论,目标可预测性是情境线索效应的关键因素。
