Abstract

Visual features previously associated with reward can capture attention even when task-irrelevant, a phenomenon known as value-driven attention capture (VDAC). VDAC persists without reinforcement, unlike other forms of learning, where removing reinforcement typically leads to extinction. In five experiments, factors common to many studies were manipulated to examine their impact on VDAC and its extinction. All experiments included learning and test phases. During learning, participants completed a visual search task during which one of two target colors was associated with a reward, and the other with no reward. During test, 1 week later, participants completed another visual search task in which the reward association was not reinforced. When a rewarded feature remained task-relevant (Experiment 1), VDAC was observed. When the rewarded feature was made task-irrelevant (Experiments 2-5) there was no evidence of a VDAC effect, except when the target feature was physically salient and there was a reduction in the frequency of exposure to the reward-associated feature (Experiment 5). We failed to find evidence of VDAC in Experiments 2-4, suggesting that VDAC may depend on the demands of the task resulting in vulnerability to VDAC. When VDAC was observed, extinction was also observed. This indicates that VDAC is subject to extinction as would be expected from an effect driven by reinforcement learning.

摘要

先前与奖励相关的视觉特征即使与任务无关也能吸引注意力,这种现象被称为价值驱动注意力捕获(VDAC)。与其他形式的学习不同,VDAC 即使没有强化也能持续存在,在其他形式的学习中,去除强化通常会导致消退。在五个实验中,操纵了许多研究中常见的因素,以检验它们对 VDAC 及其消退的影响。所有实验都包括学习和测试阶段。在学习阶段,参与者完成一项视觉搜索任务,在该任务中,两种目标颜色中的一种与奖励相关,另一种与奖励无关。在一周后的测试阶段,参与者完成了另一项视觉搜索任务,其中奖励关联没有得到强化。当奖励特征仍然与任务相关(实验 1)时,观察到了 VDAC。当奖励特征变得与任务无关(实验 2-5)时,除了当目标特征在物理上突出且接触到与奖励相关的特征的频率降低时(实验 5),没有证据表明存在 VDAC 效应。我们在实验 2-4 中未能找到 VDAC 的证据,这表明 VDAC 可能取决于任务的要求,因此容易受到 VDAC 的影响。当观察到 VDAC 时,也观察到了消退。这表明 VDAC 像受强化学习驱动的效应一样,也会受到消退的影响。
