虽然有助于个体感受到刺激物的感觉能动性的因素已经被广泛研究，但对刺激物的感觉能动性的认知影响却知之甚少。在这里，我们进行了三个实验，研究是否注意选择偏向于可控的刺激。在这三个实验中，参与者移动了四个圆圈刺激，其中一个是在他们的控制之下。然后，搜索目标出现在其中一个刺激上。在实验1中，目标总是在受控刺激上，但我们操纵了参与者的控制程度。在实验2中，控制刺激是50%的试验的目标。在实验3中，我们使用了一个中央箭头提示，告诉参与者按哪个箭头键（而不是使用自由选择任务），并使控制刺激的目标上的25%的试验，使其非预测目标的位置。在这三个实验中，我们发现视觉选择偏向于可控刺激。当参与者完全控制刺激时，这种注意力偏差更大，而不是部分，这表明代理感导致一个人优先考虑他们控制下的对象。事实上，代理影响注意力时，控制对象包含的目标在100%，50%，和25%的试验，甚至发生在参与者需要监视显示器的中心，以知道哪个箭头键按下，表明其影响并不依赖于任务的相关性或意志决策。
While the factors that contribute to individuals feeling a sense agency over a stimulus have been extensively studied, the cognitive effects of a sense of agency over a stimulus are little known. Here, we conducted three experiments examining whether attentional selection is biased towards controllable stimuli. In all three experiments, participants moved four circle stimuli, one of which was under their control. A search target then appeared on one of the stimuli. In Experiment 1, the target was always on the controlled stimulus, but we manipulated the degree of control the participant had. In Experiment 2, the controlled stimulus was the target on 50% of the trials. In Experiment 3, we used a central arrow cue to tell participants which arrow key to press (rather than using a free choice task) and made the controlled stimulus the target on 25% of the trials, making it nonpredictive of the target's location. Across the three experiments we found that visual selection was biased towards controllable stimuli. This attentional bias was larger when participants had full, rather than partial, control over the stimulus, indicating that sense of agency leads one to prioritize objects under their control. The fact that agency influenced attention when the controlled object contained the target in 100%, 50%, and 25% of trials, and occurred even when participants needed to monitor the center of the display in order to know which arrow key to press, suggests that its influence does not depend on task relevance or volitional decision-making.
